The exhaust pipe of Suzuki Kaiyue taxi dual-fuel car suddenly made noise.

1, there is a lot of water in the exhaust pipe. The reason for water accumulation is that there is too much water in the fuel used, which can be solved by replacing the fuel with better quality.

2. Too much carbon deposit in the combustion chamber, too much carbon deposit in the air inlet, and the cross-sectional area of the air passage changes. The control unit of the automobile can not accurately control the idle intake, which leads to the mixture being too rich or too lean. In this case, there will be abnormal noise in the exhaust pipe of the car, which will also lead to engine jitter, which can be solved by cleaning the throttle.
