Car engine noise can be attributed to the following reasons: 1. The engine produces a sound similar to "popping": This unpleasant engine noise is most likely caused by the engine being either too hot or too cold, or there is a high probability of insufficient oil. 2. Engine overheating leading to a loss of engine power: If the engine operates for an extended period, causing the surface to overheat, the cooling system may fail. The first step in this situation is to check the cooling system. If the cooling system malfunctions, it could lead to exhaust blockage, as the vacuum tube might be prone to cracking. At this point, steam or hot air may escape from the engine, resulting in a "hissing" sound.
