How to clean EFI engine fuel injection system

EFI engine is currently on the vehicle use a very wide range of equipment, compared with the conventional carbureted fuel system, EFI engine fuel supply system, not only complex, but also parts with precision. When using Auto Diagnostic Tool maintenance necessary to pay special attention.

During cleaning maintenance, some parts can not be disassembled and dismantled, some parts assembly requirement is high, which makes gasoline injection system than the carburetor type vehicles are more vulnerable to the dangers of gasoline in the colloid, sediment, the cleaning is very complex.

The engine fuel supply system, the air inlet and exhaust system are clean and have a decisive influence on the driving performance of the vehicle. Due to the impact with the environment and fuel quality injectors, intake manifold, intake and exhaust valves and the combustion chamber is easy to produce gelatinous precipitates, etc., affect the normal fuel supply, cause by fuel injection quantity control is not accurate, the fuel spray is bad, the oil pressure regulation failure, which causes the engine idle speed instability, the acceleration bad, knock, lack of fire, fuel consumption, exhaust emissions exceed the failure phenomenon. These faults can be using the Launch X-431 PAD or Launch X431 Creader VIII tool checked out.

In order to clean the oil supply system to solve the problem from the inside, they usually avoid demolition clean way. Vehicle cleaning jobs by special Autel MaxiDas DS708 or Autel Maxidiag Elite MD701 tools and equipment and cleaning agents, under certain pressure and flow control, intake manifold, fuel injectors, intake and exhaust valves and combustion chamber thorough cleaning to restore the normal operation of the fuel system, to ensure good driving performance of the car.

How to maintain your car sunroof

Car sunroof is a very common configuration comfort. So the question is, did you use Auto Diagnostic Tool maintenance skylight? Here we come to the maintenance of the skylight and note to do a simple introduction.

One. Skylights use a long time, at its rails, the gap will be deposited in a lot of sand or foreign objects, such as occasional clean-up, will wear the sunroof member. It should be cleaned regularly lubricated around and avoid sand deposition, to extend the service life of the sunroof seals. Generally every six months, to use gauze or cotton dipped in water to wash the sealing tape or slide, rub after a little grease can be applied. Can be used for a fine talc, can prolong the service life of the sealing ring.

Two. Use skylights biggest concern is leaking, proper use and maintenance of skylights can effectively avoid leakage. Before entering the rainy season, in addition to clean up slide, seal gap is the foreign body, but also a harness protector or talcum powder sprayed on the seals and other components.

Three. Before turning on the skylights, should pay attention to whether the roof has obstacles to the operation of the glass panel. Sunroof panel design has isolated the heat and ultraviolet function, please use a soft cloth and cleaning agent cleaning, never sticky or have corrosive cleaning agent, you can also use Launch X431 V+ Pro3 or Launch X431 V Pro tools to detect the sunroof.

Four. On the very bumpy road best not to completely open the sunroof, otherwise may have skylights and slide rail vibration between related parts deformation caused by the too big to even make the motor damage. In addition, rain or cleaning vehicle when it is forbidden to open sunroof.

Skylight is not just a piece of glass so simple, its structure is quite complex, once skylight some failures,  using Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool maintenance and replacement costs is too high, panoramic sunroof maintenance costs even higher. Therefore, the maintenance of skylights not be ignored.

Replace the automobile ATF fluid matters needing attention

Due to the popularity of cars, so many people will be familiar to car maintenance, but some people are not very understanding, so the use of Auto Diagnostic Tool maintenance vehicles, for some small details do not in place.

Replace automatic gearbox transmission fluid, it is often said that ATF fluid. Most of the cars are highly sophisticated automatic transmission power transmission device, mostly controlled by computer, equipped with a lot of precision components: torque converter, a sun gear, a planetary gear and a complex and fine oil passages and, it is very sensitive to temperature changes and other pollutants. If there is no maintenance, automatic transmission will be difficult and other gear shift. And most of the automatic transmission failure is caused by the transmission fluid pollution.

In the replacement of transmission fluid will generally in hydraulic variable torque converter and transmission cooling pipe is provided with a residual, and the residual amount is more, even with the new then residues were old contamination. In this case the use of automatic transmission cleaning agent completely remove the old fluid, to ensure that no residual old transmission fluid, can completely replace the new transmission fluid.

Under normal circumstances, each driving 50,000 kilometers, it should be connected to the device and the car's power, and the use of the Launch X431 PAD or Launch X431 V+ Pro3 adapter to connect the device and the transmission cooling tube. Start the car and let the engine is running at idle, then add the automatic transmission cleaner, slam the brakes, in order to remove harmful substances, and one by one, replace all gear of the automatic transmission, and finally with the help of automatic transmission oil equipment comprehensive replacement.

If you want an automatic transmission protective agent is added, it is preferably added in the proportion of 5% of this, If it is used for a long time, then it is best to add some stop leakage, to prevent the aging of transmission seals can also achieve the purpose of preventing leakage.

So, for the transmission fluid is a small thing, which can be a lot of things to note, the owner replaced when we must pay more attention to, and need to use professional Autel Maxidiag Elite MD701 or XTOOL VAG401 tools to detect car.

Car over speed humps Tips

Cars over some speed humps, the normal speed through the speed humps, through OBD Diagnostic Tool detection show that it will damage to the vehicle, and ride comfort have influence, encountered deceleration zone how to through?

The effect of speed humps just as its name implies is to make the vehicle to slow down, even if the vehicle is not loose throttle or brakes, the vehicle up and down motion of the reason will be because certain rate weakened. Of course, the main role of the deceleration zone or let the driver subconsciously reduce vehicle speed by this section, the initiative allows the driver to pay attention to the road conditions ahead, generally in front of the school may be crossing or continue downhill.

1. Before experiencing the deceleration zone, the first driver's consciousness is closing the throttle and tap the brakes, and pay attention to road conditions ahead, and through the rear of the rearview mirror to observe road traffic conditions, if trailing behind the vehicles more, close the throttle to reduce speed must not to slam on the brakes. It is easy to cause behind the vehicle rear end collision, you can use Launch X431 GDS or Launch X431 IV GX4 Master tool detection of brake system.

2. For automatic transmission vehicles, as well as from the deceleration zone after a short distance, according to the vehicle damping performance and road driving conditions, the vehicle speed control at 30Km / h or less, but not too low. Although the lower rate turbulence weaker sense, but it will affect the overall rate of road traffic. Vehicle speed control to a certain speed, the rear wheels begin to spin down when the band can throttle speed.

3. For manual transmission car with a manual transmission car is relatively complicated. Before entering the deceleration zone when some began to collect the oil from the deceleration and observed the traffic situation around the vehicle, and based on the vehicle speed sequential shift into low, generally 1, 2 block can be relatively stable through the deceleration zone.

In the vehicle rate below 30Km/h or lower through the deceleration zone, according to the Autel MaxiSys MS908 or Autel Maxidiag Elite MD701 detection. To a file through the deceleration zone, light step on the clutch to do linkage and throttle idle speed, the rear wheel through deceleration zone, observe the road in front, slowly lift the clutch and lightly on the accelerator, according to the speed or engine speed a step on the clutch shift into high gear. At last, the car speeds of up to normal driving state.

How to effectively prevent the car rust oxidation

Tip 1: alert subtle small flaws
Car paint surface often corroded, in addition to the common collision, scratching, driving tires up small stones to play in the paint, make the emergence of dots of a peeling paint, a long time will produce a small rust. And these small scars because most of the small, easy to be ignored. Therefore, usually to regularly use the Auto Diagnostic Tool inspection car, bonnet and body around, once found to promptly to the professional beauty shop for processing.

Tip 2: ground investigation easy to water at humidity
Vehicles traveling on the way, passing through muddy puddles, and some gaps at the underbody and interior floors, etc. are easy to accumulate sludge, such as the owner does not promptly cleaned, which makes cars rust. Thus, for doors, trunk bottom corner of the door frame of the key hole and the wipers moving parts, etc., should always use the Launch X431 V+ Pro3 or Launch X431 IV GX4 Master tool to check, while maintaining the smooth flow of the doors and body departments drainage holes, check the car cover Humidity matter , such as carpets, floor parts to prevent rust.

Tip 3: the soft paint do seal glair
Some paint softer vehicle traveling at high speed during the sand particles hit the car body may also result in a fine relying marks. For this kind of cars, glaze to body, it can form a mesh of solid protective film, improve the surface hardness, the effect can be stay for about a year. And the coating can also achieve a similar effect. Also for the bottom of the vehicle can chassis armor or a plastic sealing, which can protect chassis acid rain, corrosion protection, the original protective layer is not easy to dry and fall off, can also prevent the driving small stones the impact of the chassis.

Tip 4: Toothpaste can be temporary anti-rust coating
To deal with ordinary toothpaste. When found a new small scars, and gently wipe the toothpaste applied circle scratches. Rain or after washing, apply it. This generally reduce scratch mark, you can simply play a role in isolation, to prevent rust, through Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD702 tools to detect no problem in the short time.

Timely attention to automotive air filter maintenance

Replace "three filter" according to the use of the car, maintenance and oil quality grade circumstances, automotive air filter equivalent to the human nose, the air entering the engine to go through the first hurdle, Filter the air through the blocking effect of filter paper. When the dust of the filter paper surface of the pores, it will cause blockage, which directly affect the car's engine, unimaginable consequences occur. Because the air filter and direct contact with the outside world, so it is easy to be blocked, through Auto Diagnostic Tool check found engine will accelerate the powerless and idle instability, and other symptoms, the normal work of the air filter can avoid premature engine wear and maintain the best working condition.

The density of the atmosphere contains three different basic particle contaminants that dust, debris and soot. Open highway dust content is low, but emissions from vehicles concentrated, so that the content of carbon particles in the air is significantly higher, and therefore frequently used Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the air filter. The dust concentration in the larger areas such as construction sites, sand area, air filter inspection and replacement frequency to be higher. Also now the majority of automotive air filter is made of paper, when the damp air filter, intake blocked, weak acceleration of the vehicle becomes more serious when the water is drawn into the interior of the engine into the cylinder, since water is incompressible, seriously damaged will cause the engine internal moving parts, engine even scrapped.

Few people noticed it, but auto parts Once the problem occurs, the result is the most serious threats to travel safety, not because these small parts and components affecting the active force of the car, so regular use Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool to check car engine working conditions.

Regular maintenance and check car handbrake

In the big city in the congestion of the car, the vehicle before and after the gap is basically less than one meter, and the slope of the overpass is very large, parking brake is particularly important. However, due to various reasons, the handbrake will appear when no use. In the daily inspection and maintenance of the vehicle, don't forget to use Auto Diagnostic Tool to check the performance of regular handbrake.

First, determine the operating position of the handbrake lever. Generally, when the handle is pulled three-quarters of the entire trip, the hand brake system should be in a normal brake position. Should first find out the work point, the general 5~7 case is normal position. Then check the brake mechanism efficiency, also is have a look handbrake to work effectively. The car drove up to the steep, good road conditions of the slope, step on the brake pedal, the neutral gear, pull the hand brake handle to just to determine the position of. Slowly loosen the brake pedal, if the car did not happen sliding, that means the hand brake performance is good.

Check the handbrake sensitivity, since it is very important to the slope. On flat roads slow driving, slowly pulling handbrake handle and feel the sensitivity and the junction of the handle. If it is found that the brake braking efficiency or sensitivity is not ideal, can regulate the handbrake thread through Launch X431 PAD or Launch X431 GDS tools to solve.

Adjust the hand brake wire. If found in the test the brake is not sensitive, can be solved by adjusting the handbrake arrows, below the hand brake handle with an adjustable compensation institution. Adjust the need to remove the handle decoration cover first, then use tools to adjust the length of stay, in order to ensure the hand brake is in the best working state.

Ordinary driving, the handbrake usage is very high, but the handbrake is not universal insurance, its performance will decline with the increase of using the number of times. Most of the time, because the system failure or improper use and don't effect, this is also the major hidden danger of the accident, so owners should regularly use the Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools maintenance check handbrake.

What causes a car to knock and car knock solutions

New buy the car engine appears knock phenomenon. I believe that there are some people who have a little in-depth understanding of the working principle of the automotive engine, should understand the engine appears knock whether quality problem. if you don't have any information about the engine of the car, then we look together, what is knocking? Why the engine will knock? What effect does the knock have on the engine? How to avoid the engine knock? Why use the OBD Diagnostic Tool to check the engine knock?

The so-called "knock" is not to say that engine would explode or violent shaking, but refers to the gasoline engine before the spark plug without ignition, sprayed into the cylinder fuel is because of the cylinder body and the high temperature and the occurrence of spontaneous combustion of a non normal phenomenon. The spontaneous combustion will not only cause engine cylinder in local temperature is too high, can not let fuel to participate in the work of the engine, resulting in power output in serious decline, resonance between the piston and cylinder wall, because of abnormal vibration caused by explosion is called "knock".

Engine knock is actually the most important reason is that gasoline grade is too low, we often say that the number 92, number 95 refers to the grade of gasoline, Gasoline label is neither refers to the purity, nor does it imply a lot of people often say that the so-called octane number, but gasoline anti-knock index, also known as anti-knock index.

Focus, Mazda 3 and other vehicles encountered the "knock", the manufacturers solution is to use Autoboss V30 SPX or AUTOBOSS V30 Elite tool for trip computer upgrade, the knock problem is solved.

Engine knock is not the most important step to upgrade software part, the modern automobile engine through hardware modifications also cannot let knock disappear, essentially the only solution is based on the actual demand of the engine, the correct selection grade of gasoline .

Recommend vehicle appear knocking, first switch to high-grade gasoline, suppress the occurrence of knocking fundamentally. Try to avoid prolonged idling stop, avoid high gear low speed driving, automatic models accelerate to overtake, use low gear when climbing or manual shift mode, can effectively reduce the production of coke, to suppress detonation engine protection is also very favorable. Timely use Autel Maxidiag Elite MD701 or Autel MaxiDiag EU702 tool to check the engine, regularly clean the throttle, using high-grade synthetic oil can also reduce the incidence of carbon, the same can effectively avoid the generation of knock.

Paper air filter installation and maintenance guide

Through Auto Diagnostic Tool checking data found paper air filter has the following advantages:
1) Filter efficiency up to 99.5% (oil bath air filter 98%), dust transmittance of only 0.1% -0.3%;
2) structure compact, can be installed in any orientation, not by vehicle parts layout constraints;
3) when maintenance is not consume fuel , but also save a lot of cotton yarn, blankets and metal materials and other substances;
4) the quality of small, low cost.

Based on the above advantages, car engines use air filter paper core is becoming more common. The key of good paper air filter is to keep its sealing performance, prevent unfiltered air from bypass entering the engine cylinder.

Paper air filter installation and maintenance guide
1. During installation, air filter and the engine intake pipe between rubber pipe coupling or direct coupling must be tight and reliable, to prevent leakage, the filter must be installed at both ends of the rubber gasket surface; fixed wing air filter housing nuts can not be tightened too much, so as not to crush paper filter.

2. In use, the air filter to prevent rain water paper, because once a large amount of water adsorbed paper, will greatly increase the intake resistance, shorten the service life.

3. Some vehicle engine is equipped with Tornado air filter, paper filter ends of the plastic cover is shroud cast blades rotating air, Launch X431 IV GX4 Master or Launch X431 V+ Pro3 tool data showed that: 80% of the dust separated by centrifugal force and collected in collection Dust arms, to dust paper filter for inhalation of dust was 20%, the total efficiency is about 99.7%.

4. During maintenance, paper filter never use oil cleaning, otherwise the paper filter will be failure, but also easily lead to accidents. When maintenance, use only the vibration method, soft brush division (which folds down to brush) or compressed air cleaning methods remove the attachment surface of the filter paper dust, dirt. Part of the strainer, should be promptly removed the dust parts, pipes, etc. of leaves and cyclone dust. Even if every time meticulously maintained, the paper filter can not completely restore the original performance, the intake resistance will increase, therefore, generally when the paper filter is required when the 4th maintenance, it should be replaced with a new air filter. If the paper filter rupture, perforation or unglued paper and cover other issues, should be replaced immediately.

Air filter is the air enters the engine from the first hurdle, automobile engine is very precise parts, the tiny impurities will damage the engine. Therefore, in the air into the cylinder before, must first go through the fine filtration of air filter, can enter the cylinder. You can use the Autel Maxidiag Elite MD701 or Autel MaxiTPMS TS601 tool regularly to check the engine, and the air filter status is related to the engine's life.

What are the reasons for auto body shake

Auto Body slight jitter situation many owners often encountered. If the owners to start the vehicle or the vehicle is not suspended off the engine case, if you find a slight shake the car body, it may mean that the following three conditions exist vehicle:

If the driving process, found the body there is a slight jitter or offsets, it is generally caused by tire failure. First, the tire may be poor balance, you need to go as soon as to the car repair shop to do the wheel alignment and balancing, there is a simple way, using Auto Diagnostic Tool to do a correction.

Another condition is more serious, possibly because rim distortion, which requires owners to go to a professional repair shop to check. This situation generally occurs in the use of five-year vehicles. General motors to replace the new tires, new rims when to do a tire balance, otherwise the weight does not mean when the steering wheel is prone to jitter phenomenon. The body jitter can have an effect on driving comfort and control judgment. There is also a simpler way, using the Launch X431 GDS or Launch X-431 PAD tool to check whether the tire is balanced, if the balance, is not required to the repair shop.

The third case is because the transmission shaft deformation caused by the imbalance, it typically occurs in the chassis of the car had a collision.

If there is to start car the body shaking, the fault is for equipment manual transmission vehicles, such as: from static started and slowly lift the clutch pedal, the vehicle vibration. This is due to a clutch three piece suit (flywheel, clutch plate and pressure plate) the irregular wear, in which one or a few pieces to produce deflection caused by, in the bonding process, clutch disc can not be smoothly joined, but a joint, a little and release of the engine power is just beginning to transfer, and suddenly slipped, replace the clutch three sets of damage, in using Autel Maxidiag Elite MD701 or Autel AutoLink AL609 tool for the detection of gearbox is working properly.
