5-year-old car valve cleaning valve

Throttle is a controllable valve to regulate the air entering the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and then it will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. Then, do you want to clean the valve of the five-year-old car?

Introduction to knowledge classification

There are two kinds of throttle valves: traditional cable throttle valve and electronic throttle valve. The traditional engine throttle control mechanism works through a pull wire (soft steel wire) or a pull rod, one end of the pull wire is connected with an accelerator pedal, and the other end of the pull rod is connected with an accelerator linkage plate. The key of electronic throttle is to adjust the throttle opening according to the energy required by the engine through the throttle position sensor, so as to adjust the intake air.

Brief introduction of knowledge maintenance methods

How to clean and prevent should pay attention to:

1. Demolition and cleaning should be done well;

2. Correct some misunderstandings of throttle cleaning;

3. Through development and change.

The key cause of throttle scaling is oil vapor, followed by particles and moisture in the air, that is to say, using qualified air filter and removing crankcase ventilation pipe, throttle scaling speed will be much slower.

The crankshaft is built in the crankcase, and its lower side is connected with the oil pan. The working temperature of the module is100℃ ~180℃; Up and down.

Introduction to knowledge failure

The composition of electric throttle can be roughly divided into the following parts: throttle, electromagnetic driver, potentiometer, regulator (part of which is not directly controlled by ecu) and bypass valve. Its fault characteristics are divided into two categories: hard fault and soft fault. Hard fault refers to mechanical damage, and soft fault refers to dirt, dislocation, etc.

Ok, today, the rider editor briefly introduced that the car with a car age of 5 years needs to clean the valve. That's all. I wonder if they have a deeper understanding of the necessity of cleaning the valve after listening to the brief introduction of the car editor. I hope the profile of Bianxiao Automobile can help my friend. If you want to know more, pay attention to this website. Bian Xiao's car is waiting for you here!
