Spark ignition refers to the process of initiating combustion in an internal combustion engine using an electric spark generated by a spark plug. This method is commonly used in gasoline engines, where the air-fuel mixture is ignited to produce power, and it contrasts with compression ignition used in diesel engines. Spark ignition systems are crucial for the efficient operation of dual-fuel and flex-fuel combustion systems, allowing for versatility in fuel choices and optimizing performance.
