How often does Mazda cx4 throttle have to be cleaned?
Throttle is a controllable valve, which controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. 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 electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, so as to adjust the intake air.
There are four types of electronic throttles: electro-hydraulic type, linear electromagnet type, stepping motor type and DC servo motor type. However, electro-hydraulic type and stepping motor type are rarely used in automobiles because of their low control accuracy, and linear electromagnetic type is rarely used in automobiles because of its high power consumption. DC servo motor can overcome the above two situations well, so it is widely used in automobiles. In addition, the throttle valve also needs to be replaced regularly, and the length of time mainly depends on the quality of the air filter, oil quality, vehicle road conditions and other factors.
Throttle fouling is mostly caused by poor air quality and poor oil quality. Due to the negative pressure, the carbon deposit produced in the process of gasoline combustion will infect the throttle valve, which will make the throttle valve not close well, thus increasing the intake air, causing signal transmission errors, leading to high fuel consumption and engine idling jitter.
