How to clean the throttle of diesel engine

Cleaning method of engine throttle: 1. First, remove the intake throat to expose the throttle, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle, and then carefully scrub the deep part of the throttle with a polyester rag or a high-spin "non-woven fabric". You can hold the rag and scrub it carefully. 2. After cleaning, it is necessary to start the initialization of the throttle according to the disassembly procedure just now. After cleaning the throttle valve, it needs to be initialized, because the computer has a memory function when adjusting the throttle valve opening, because there was sludge blockage before. In order to ensure the air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state; 3. There is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, it will lead to excessive intake air. As a result, the engine jitter and acceleration are weak when starting, and the engine fault light may be on.
