Causes of weak car engines
There are many different reasons why a car runs weakly and accelerates slowly.
Fuel filter clogged
This is considered one of the common causes of weak cars and slow acceleration.
If the fuel filter is not cleaned for a long time, it will accumulate dirt. Therefore, users need to pay attention, regularly check and replace it periodically.
Regular inspection will prevent the filter from becoming clogged, causing the amount of fuel pumped into the combustion chamber to be insufficient, affecting the engine's performance.
Clogged injector
Injectors are parts that are often covered with dust, affecting the vehicle's performance. Therefore, users need to pay attention to cleaning them periodically.
Failure to clean regularly will cause the injector to become clogged, affecting the fuel flow and timing. This problem will significantly affect the efficiency of the engine ignition process, leading to the car accelerating slowly, the car losing gas, the car being difficult to start...
Low cylinder pressure
To operate stably and at full capacity, the cylinder must have high pressure. The higher the cylinder pressure, the higher the compression. If the compression is low, the power generated will be low, leading to the vehicle running weakly, accelerating slowly, and not being able to accelerate.
Worn spark plug
Worn spark plugs will result in insufficient spark and ignition timing. This problem will reduce operating performance, especially the combustion of the air-fuel mixture, thereby reducing engine power, causing the vehicle to accelerate poorly.
The exhaust pipe is clogged.
Catalytic converters help reduce the amount of pollution in exhaust gases. If the catalytic converter fails, it can cause the exhaust pipe to become clogged. When the exhaust pipe is clogged, the engine will use more energy to push the exhaust gases out. This reduces engine power. In addition, a clogged exhaust pipe can cause reverse flow, the exhaust gases cannot escape and return to the combustion chamber, affecting the engine's ignition process, causing the car to accelerate slowly, the engine to become weak, etc.
