What is the octane improve agent

What is the octane improve agent? What does it do? Octane improver is to increase the octane rating of automotive additives, can be used OBD Diagnostic Tool to check out the car's octane, octane improve agent is a kind of common gasoline additives, which is popular in the additive products.

The most effective way to improve the engine efficiency is to improve the engine's compression ratio, but the compression ratio of an increase, knocking combustion significantly enhanced, higher-octane gasoline can reduce detonation, as the engine compression ratio continues to improve, This forced refineries to produce high-grade gasoline. Octane increase only to reduce engine knock, and reduce fuel consumption, thereby increasing the economic efficiency, Launch X431 V Pro or Launch X431 PAD tool inspection data show: Improve the gasoline octane number 1 unit, saving gasoline 1.3%.

For a long time, oil prices have been stubbornly high, bring the owners a little cost pressures, how to reduce the fuel consumption has been a concern. In addition to source fuel from outside, how can the existing fuel play to the best effect is also very important. Presumably this is the octane value improver where it! Improving fuel quality, to the full combustion, reducing fuel consumption.

Of course, as a gasoline additive, in the selection or according to the specific circumstances of their own car, everything from reality, the effect of the additive to play to the largest , you can use the Autel MaxiScan VAG405 or Autel MaxiDiag FR704 tool to check, it will prompt you to use what kind of gasoline additive.

Audi A6 engine abnormal sound fault analysis

Audi C5A6 equipped with 1.8T engine and automatic transmission, driving mileage of 50000 km. Car owners reflect the engine in 2,3 gear acceleration have abnormal noise, the abnormal noise has lasted about half a month's time, through the OBD Diagnostic Tool to check, the sound becomes apparent.

After testing, in 2, 3 block accelerated heard engine abnormal noise, listen to the voice really like engine knock, but the power of the engine were not affected by any effect, accelerate the engine sound all normal. Combined with the failure analysis, the engine at 2,3 gear acceleration can send different sound There are several reasons:

(1) variable valve timing mechanism fault. Because in the 2,3 gear acceleration engine has entered the medium-load conditions, according to the characteristics of the engine, the valve timing should have entered the adjustment position, adjust the mode by changing the position of the chain tensioner to achieve. According Launch X431 V Pro or Launch X431 IV GX4 tool check, found that when the chain camshaft adjustment, if the chain tensioner lack of strength will make the chain in a relaxed state in the adjustment process and beep.

(2) Since the engine knock sound is generated. That there are several possibilities: ① fuel octane low lead to knock. This car's engine may be use 93 unleaded gasoline, it is best to use 95 unleaded gasoline, otherwise it will produce detonation. ② ignition timing is premature detonation. To further understand the failure, you can use Autel MaxiScan MS509 or Autel MaxiScan VAG405 tools to detect, which can quickly check out the car parts problem.

Automobile brake system five common sense

The brake system is the guarantee of a car can at any time according to the driver's intention to slow down or even stop system, brake system is very important so that you can use the OBD diagnostic tool to check to ensure that the brake system to work properly. Look for Car Brake System 5 tips:

1, ABS warning light in the instrument lights up, please as soon as possible to the 4S shop inspection and handling, to avoid affecting traffic safety and travel delays. If you have Launch X431 IV GX4 Master or Launch X431 Diagun III diagnostic tool, you can check your car's problem, no need to 4S repair shop.

2, Loosen the brake after start, heard a friction brake pads and brake discs, this is normal phenomenon.

After starting the engine, the driver will be put on the brakes to shift after operation, loosen the brake vehicles running start, after gear hangs in the brake pads and brake discs have been carried out under normal temperature conditions, but did not produce great friction, vehicle gear will produce forward or backward driving force, this time release the brake pedal, the brake pad and the brake disc will produce sound. If the brake disc at the car wash water this voice will be more obvious.

3. The parking brake cable growth after a period of time: This is normal. Handbrake cable is composed of multiple sets of wires, the force after a certain ductility, in use for some time, it will have a certain elongation than the length of new car, and will not have any impact on the parking brake .

4, Brake disc rusty: the brake disc main component is iron, the vehicle is not used for a long time, the disk surface will have some rust, but the vehicle is in motion through the work of the braking system, would eliminate rust, does not affect the normal use.

5, The brake disc after the use of fever: a normal phenomenon. Brake is by friction brake pads and brake discs to achieve, is the kinetic energy is converted into heat energy in the process, it will generate heat. Keep your hands after touching the parking brake discs, to avoid burns. If you're still worried, you can use Autel MaxiDas DS708 or Autel MaxiScan VAG405 tool checks to ensure road safety.

How to prevent and timely maintenance of automobile oil spills

In the use of the car, often leak failure occurs, it will directly affect the technical performance of the car, leading to oil, fuel waste, power consumption, the impact of the car clean and tidy, causing environmental pollution. Because oil spills, reduce internal engine oil, resulting in poor mechanical lubrication, insufficient cooling, can cause mechanical damage early, even leaving accidents.

First, The common main reason for the vehicle oil spill

1, the product (accessories) quality, material or workmanship is poor; structural design problems.

2, improper assembly of high speed, with the dirty surface, liner damage, displacement or failure to standardize procedures for installation.

3, tighten the nut force uneven, slippery silk buckle or break off as a result of work Songkuang failure.

4, after long-term use of the sealing material wear off limits, aging metamorphism, deformation failure.

5, lubricants add too much oil too high or mistake of oil.

6, parts (side cover type, thin-walled parts) engagement surface deflection, the housing is damaged, so that oil leakage.

7, vent plug, after the check valve plug, due to the pressure difference inside and outside the enclosure role, often lead to seal leakage weaknesses.

Second, Oil spill prevention measures of vehicle

1, emphasis on cushioning effect. Automotive standing parts (such as the end face of each engagement, each cover, shell, cover mats, flat enamel cover, etc.) gasket leak-proof seal between components plays a role. If the materials, production quality and installation does not meet the technical specifications, leak-proof seal would not achieve the role, and even accidents. Such as the oil pan or valve cover, due to the large contact area and difficult to compaction, the resulting oil spill. Note that when handling properly placed, carefully check the press specification assembly.

2, various types of fastening nut torque the car are tightening regulations required. Too loose, not tight pressure pads would leak; they will screw around tight metal bumps or threaded twist slip caused oil spills. In addition, the oil pan drain plug back if not tighten or loosen off, likely to cause oil loss, and subsequent "bush-burning axle" of engine damage accident.

3, the timely replacement of seal failure. Many parts of the car moving home (such as oil seals, O-rings) due to improper installation, journal and seal edge misalignment, yaw and dumped oil. Some seals used for a long time due to rubber aging and loss of elasticity of the canal. Found leakage should be updated.

4, auto parts used for a long time will produce excessive wear limit (eg, such as piston and cylinder), resulting in the combustion chamber of high pressure gas into the crankcase, and forcing the oil leakage. Therefore, when added to the oil filler cap emissions at channeling serious, should try to repair or replace worn parts.

5, to avoid a one-way valve, vent valve blocked. The resulting temperature rise within the housing, oil filled the entire space, not the canal discharge, increased pressure within the housing so that oil consumption growth and replacement cycles. After the engine ventilation system is blocked, increasing the resistance movement of the piston, so that the fuel consumption increases. Due to the pressure difference inside and outside the enclosure role, often lead to seal leakage weaknesses. Hence the need for regular inspection of the vehicle, and clear, clean.

6, various types of pipe joints sealed properly addressed. Car union nut often removable, easy to slip off the buckle and loose wires; two joint bell poor accuracy, the two do not coincide with the center line of the cone and the bad; not coincide different taper, which will cause oil leakage . Replace the union nut with grinding solve its cone seal, compression nut and resolve seal.

7, to avoid rejection oil hub. Wheel bearings and grease cavity excessive or improper seal assembly, poor quality and aging failure; wheel brake frequently caused by high temperatures; axle nut loose, and this will lead to rejection of the oil hub. So useful "cavity lubrication" vent clear, strict selection of high-quality accessories, according to the high-speed assembly and process specifications.

Third, the maintenance and overhaul of the main points of the vehicle

In extremely clean conditions for assembly, parts work surface no bump, no scratches, burrs and other fixtures; strict rules, seals should be properly installed, do not be put in place to prevent deformation; grasp performance specifications and requirements of the seal timely replacement of failed parts; side cover classes for thin-walled parts, the use of sheet metal cold do correction; easy to wear shaft hole type parts can be metallized, repair welding, gluing, machining and other processes in order to achieve the original size; try using a sealant, if necessary, can paint to achieve the desired sealing effect of alternative; slide wire nut off button, release should be repaired or replaced with new parts, and tighten to the specified torque; should be carefully examined before the appearance of quality rubber seal assembly; use press with specialized tools, to avoid distortion beat; filling grease required regular cleaning to clear the vent and check valves. Just do the above, the vehicle is completely leak problems cure.

Some car diagnostic tools will help you test out your vehicle on your own, for example: Launch X-431 PAD, Launch X431 Diagun III, Autel MaxiDas DS708, Autel MaxiScan VAG405 and so on.
