What is the fault of neutral automatic throttle boom?

The neutral automatic throttle may be caused by the dirty throttle, so the car is on the verge of stalling. At this time, the on-board computer will intervene to prevent the speed from being adjusted after the flameout. The fault of the throttle sensor leads to the wrong feedback information, and the speed is automatically adjusted.

When the throttle hits neutral, the engine often rotates too fast because there is no resistance limit. In fact, in the neutral state, the engine speed will quickly climb to a very high level by lightly stepping on the accelerator. This is not good for the engine. Because high speed is easy to cause abnormal wear. So it is not recommended to hit the throttle in neutral. It is recommended to go to the 4S shop for inspection and maintenance as soon as possible.

Harm of neutral automatic throttle lever of automobile:

When the car is in neutral, the engine has no power output. Then boom throttle, engine speed rose sharply, piston,

When moving parts such as connecting rods are accelerated rapidly, they will produce great acceleration and bear great alternating load. The stress of piston, piston pin, connecting rod, connecting rod bolt and crankshaft will exceed the stress during normal operation.

Affect the reliability and life of the engine. At the same time, the speed increases sharply when stepping on the gas pedal. The lubrication of each friction pair will also fail to keep up, which will easily lead to cylinder pulling, lava and other failures. Therefore, neutral throttle should be avoided.

Booming the throttle after starting in the cold state is also very harmful to the automobile engine. If the lubricating oil does not cover the oil film of the internal parts, it will excessively wear the metal mechanical parts of the engine. If the cooling system is not circulating well, it is easy to overheat the engine. After excessive grinding of piston ring and cylinder barrel, the sealing performance will be weakened, and there is a danger of cylinder explosion when burning engine oil or even dry grinding.
