What happened to the car that accelerated the filming?
1, ignition system failure.
If the spark plug is aging or invalid, deep stepping on the accelerator may make the fuel unable to ignite, resulting in cylinder loss and sound shooting in the exhaust pipe;
2. Improper adjustment of valve clearance
Improper adjustment of valve clearance will affect the intake and exhaust efficiency of vehicles. At this time, the power of the vehicle is weakened and the exhaust pipe will make abnormal noise;
3, exhaust pipe perforation
If the exhaust pipe is perforated, the back pressure of the vehicle exhaust will be reduced, and at the same time, the exhaust will overflow at the perforated position, resulting in shooting sound.
4. Three-way catalytic converter is blocked
Three-way catalytic converter mainly filters and catalyzes pollutants in exhaust gas, which is easy to be blocked after being used for a period of time and will affect the exhaust efficiency of vehicles.
Methods to solve the problem of exhaust pipe shooting
First look at the choke valve, and then look at the main nozzle. If oil leakage is found, it means that the oil level in the float chamber is higher than normal and should be adjusted to a normal and appropriate range. In addition, the air filter should also be replaced. If a lot of black smoke is found in the exhaust pipe, the ignition timing should be corrected.
Second, simply check the spark plug, clean the lower throttle and injector, and check the ignition timing and crankshaft position sensors, mainly oxygen sensors and intake pressure sensors.
