Why Does the Engine Make Abnormal Noises When Accelerating?
2 Answers
Possible causes include issues with the filter, spark plugs, ignition wires, gasoline, fuel filter, carburetor, or fuel pump. Below are some related explanations about the causes of abnormal engine noises: 1. Abnormal noises caused by irregular operation: After starting the vehicle, the noise can be heard even from a distance, and the engine runs extremely unevenly during operation. It also consumes engine oil and coolant quickly. This is caused by early ignition timing and requires adjustment of the engine's ignition timing. 2. Cylinder gasket noise: Cylinder gasket noises mostly occur when the engine is cold and are less noticeable when the engine is warm. The cause is excessive valve clearance, which leads to collisions between the valve stem and the rocker arm, requiring timely adjustment of the clearance.
When stepping on the accelerator to speed up, the engine makes abnormal noises, which I've experienced several times and it's quite annoying. The most common causes are aging spark plugs or excessive carbon buildup, leading to uneven ignition and producing knocking sounds during acceleration. A hole in the exhaust pipe is another common reason, with high-speed airflow impacting the metal. Loose or worn belts, such as the timing belt or alternator belt, can squeal under increased load. Low fuel pump pressure or clogged injectors can cause the engine to make gasping-like noises. Don't forget that a dirty air filter restricting airflow can also trigger noise. It's recommended to first check the spark plugs and belts; replacing spark plugs yourself is easy, cheap, and effective. If that doesn't work, quickly visit a repair shop to inspect the exhaust and fuel systems, otherwise, increased noise can lead to higher fuel consumption and damage to the car.
