What is the reason for Mazda Artz's idling jitter?

Cause analysis The direct cause is the low idle speed. For example, the idle speed was around 700 in the fifth national emission reduction era, and it was also reduced in the sixth national emission reduction era, reducing a certain proportion of emissions. But don't speed up. Using a computer to brush the speed, the vehicle inspection will encounter emission problems after a long time.

However, the working condition of the engine has not been improved because of this emission requirement, but the vibration of the engine has increased, leading to the idling jitter of the car. At this time, if we improve the lubrication conditions of the engine or improve the combustion efficiency, the vibration of the engine will be significantly reduced and the corresponding idle jitter will disappear.

At present, most of the methods to improve engine working conditions quickly are to realize super lubrication of engine oil, that is, after the lubrication state of the engine is improved during working, the vibration of the cylinder will be obviously reduced. This kind of lubrication generally changes the lubrication mode of oil into rolling lubrication mode, just like bearings, which are lubricated with small balls instead of lubricating oil directly.

Solution 1. Improve the anti-wear performance of the engine and change ordinary lubrication into super lubrication.

At present, the popular way is to add general extreme pressure antiwear agent to the original engine oil. This kind of antiwear agent can complete rolling lubrication protection within tens of kilometers, and then the working condition of the cylinder will be obviously improved, the throttle will be light, the noise will be obviously reduced, and the power output will be obviously stronger because of super lubrication at the same speed. At this time, the engine vibration is obviously improved, and the idling jitter will be greatly improved.

2. Improve the combustion efficiency and improve the engine working condition after improving the combustion performance.

Combustion efficiency is also an important factor leading to the working condition of the engine. High-efficiency combustion will make the piston of the engine run completely in super-lubrication state under the action of extreme pressure antiwear agent, and the upper and lower dead points will run completely every time the piston works. So that idle jitter does not occur due to low idle speed. Generally, the fuel tank is also added with Sioupu stock solution to improve the combustion efficiency.
