[OEvan]

Occasional abnormal noises in cars may be caused by engine malfunctions, transmission issues, or abnormal window materials. Below is a detailed introduction about car engines: Overview: A car engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems, among others. Others: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have lower manufacturing costs. Diesel engines have higher compression ratios, better thermal efficiency, and superior fuel economy and emission performance compared to gasoline engines.
