How to Clean Engine Throttle of Kia k3 Automatic Transmission

One: first remove the air filter, then remove the throttle, unscrew the four screws, remove the throttle, then spray the cleaning agent and rinse it with water.

Two: The main cause of throttle scaling is engine oil vapor, followed by particles and moisture in the air. In other words, using qualified air filter and removing the crankcase ventilation pipe will slow down the throttle scaling. The crankshaft is built in the crankcase, and the lower part is connected with the oil bottom. The working temperature of this part is about 100 ~ 180.

Three: oil will volatilize when used. The longer it takes, the higher the temperature and the stronger the volatilization. In addition, the compressed gas in the cylinder will squeeze into the crankcase through the gap of the piston ring, so there must be a channel for the gas to escape, otherwise the oil bottom will form positive pressure. The reason why the crankcase ventilation pipe is connected to the throttle valve is the requirement of environmental protection on the one hand, and the gas is pumped out of the crankcase by using the negative pressure of intake air on the other hand. When the oily steam reaches the intake pipe and cools, the oil in it will condense on the intake and throttle valve, and then the carbon deposit in the steam will also be deposited on these parts. Because the air flow is the largest in the gap where the throttle valve is opened, the space is small and the gas temperature is low, this part is the easiest to condense.
