What effect does the throttle have on the car?

The neutral throttle of Pacific car network will make the moving parts of the engine bear great inertial force, which will 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.

When the car is in neutral, the engine has no power output. At this time, when you step on the accelerator, the engine speed rises sharply, and the moving parts such as piston and connecting rod accelerate rapidly, which will produce great acceleration; Therefore, the piston, the piston pin, the connecting rod, the connecting rod bolt and the crankshaft bear great alternating load, and the stress will exceed the normal working stress.

According to the different settings of different models, some manufacturers have restrictions on the speed of neutral engines, which can be increased to about 3000 rpm at the highest; However, some manufacturers have no restrictions and can increase the maximum speed of the engine. If it is an old model, you can step on the red line to cut off the oil, because the engine computer of many old models can't perceive whether the vehicle is driving, so you can step on the speed very high. But the new car can't. The new engine computer can sense the driving state of the vehicle. When the maximum speed of the new model is about 4000, the engine will automatically cut off the oil.

But you can slam on the accelerator once in a while. Because when the engine is running at low speed, the mixture is often not fully burned, which will cause carbon deposition for a long time, affecting vehicle performance and environmental protection parameters. Booming the throttle from time to time can make the mixture burn more fully and effectively avoid carbon deposition.
