What is the cause of air leakage before the accelerator of Zotye t600?

The air leakage in front of the throttle of Zotye t600 in Pacific Auto Network is due to excessive carbon deposition on the inner wall of the throttle, which leads to air leakage at the throttle. It is necessary to clean the throttle valve to eliminate this problem. After cleaning, wipe the inside of the throttle with a paper towel, and then put the air inlet of the air cleaner back in its original position, and the operation is completed.

The air leakage of automobile throttle is mostly caused by the air leakage at the interface between throttle seat and intake seat. In severe cases, air leakage here will blacken the corresponding parts of the hood. This is because the intake pipe joint seat is made of plastic, and only four screws are fastened on the throttle seat, or the screws are loose or improperly fastened after the throttle valve is disassembled and cleaned, resulting in deformation and air leakage of the intake pipe joint seat.

1. Simple methods can be used for maintenance. Take a thin piece of oil-resistant rubber, cut out the outline and through hole according to the die print of the inlet pipe interface seat, add it to the interface between the throttle seat and the inlet pipe, and fasten it with screws. However, be careful not to apply sealant to the rubber to avoid damaging the oxygen sensor.

2. Improve the starting performance of A-type in-line pump with packing. After replacing the starting enrichment solenoid valve, it is difficult to start the engine because of improper pump adjustment or different pump hole sizes in the valve, and the working stroke of the starting shaft is not enough. In this case, the starting performance of the fuel injection pump can be improved by appropriately adding 2mm thick gaskets at the solenoid valve (starting enrichment) and the governor housing to increase the working stroke.
