How long does it take to clean up the carbon deposit on the accelerator?

30 minutes \x0d\ 1. Turn off the ignition switch, remove the accessories and connecting pipes around the throttle, and remove the throttle body; \x0d\2。 Spray oil sludge and dust in the main channel of throttle body with special cleaning agent; \x0d\3。 Open the valve plate of the throttle body by hand, and the part that cannot be cleaned is blocked by the edge of the valve plate before cleaning; \x0d\4。 Open the valve plate of the throttle body by hand and clean the part blocked by the edge of the valve plate before; \x0d\5。 In some parts of the main channel, the dirt will gradually harden after a long time, and it is difficult to completely remove it with special cleaning agents. At this time, it can be wiped repeatedly with a soft cloth, and it must not be scraped off with a hard object, which will cause physical damage to the surface of the channel and change the air flow. \x0d\ After cleaning the electronic throttle, you need to make basic settings to learn the idle speed of the electronic throttle, otherwise the engine speed may be reduced after reinstallation. \x0d\ Reasons for carbon deposition on throttle \x0d\ The reasons for throttle scaling mainly come from oil vapor, followed by particles and moisture in the air, that is to say, using qualified air filters and removing crankcase ventilation pipes will slow down the throttle scaling. \x0d\ 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. Engine oil will be heated and volatilized during use. The longer the use time, the higher the temperature and the stronger the volatilization. In addition, the compressed gas of 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. \x0d\ The reason why the crankcase ventilation pipe is connected to the throttle valve is that on the one hand, it is an environmental protection requirement, and on the other hand, it uses the negative pressure of intake air to extract gas from the crankcase. 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 gap where the throttle valve is opened has the largest air flow, small space and low gas temperature, this part is the easiest to condense.
