08/28/25 5:57am
Car engines are the power-generating devices for automobiles, serving as the heart of the vehicle and determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. There are many reasons for engine misfires, which can be broadly divided into two main aspects: 1. External components: Damage to external parts, primarily components around the combustion chamber such as valves, valve seats, valve guides, and spark plugs. 2. Internal: Misfires caused by the failure to ignite or delayed ignition of the air-fuel mixture inside the cylinder.
