1, the exhaust pipe is leaking. When air leaks from the intake and exhaust pipes, the vehicle will accelerate and the exhaust speed will increase. At this time, there will be a loud roar of vehicles.
. The throttle is dirty and blocked. When the car accelerates, the load on the engine begins to increase. At this time, it is necessary to increase the throttle opening and increase the fuel quantity. If the throttle opening is not opened to the optimal position due to dirty blockage, it will cause poor engine mixing ratio and make noise when accelerating.
The engine cylinder is missing. Engine cylinder shortage mainly refers to the abnormal operation of one or more cylinders of the engine, which is usually manifested as: insufficient power of the vehicle, and serious jitter of the exhaust pipe, and the engine can obviously hear the "sudden" or plop, plop roar.
In addition to the roar, there is often a buzz when the engine accelerates.
Reason:
1, gearbox problem: the hum generated during acceleration is not necessarily from the engine, but may also be caused by the wear of gearbox bearings, the reduction of lubricating fluid and the friction.
2. Engine problem: If it is indeed the hum of the engine, see if the speed is very high. If the speed increases and the vehicle speed increases slowly during acceleration, this situation is generally that the clutch slips and the clutch kit needs to be replaced.
3. Other problems: If noise occurs during steering, check whether the ball head and booster pump are faulty. If there is noise when braking, it may be that the brakes will wade, resulting in rust or debris residue on the brake pads. If there is noise when turning on the air conditioner, consider checking whether the air conditioner compressor pulley slips.
