The spark plug is a key component of the internal combustion engine that plays a role in generating flames so that the combustible mixture in the cylinder can be burned in optimal condition.
Glow plug is installed in the combustion chamber of a diesel engine to assist in cold start, and recently operates during idling after start, thus reducing emissions by assisting in stable combustion.
The oxygen sensor measures the oxygen concentration in the exhaust gas discharged from the vehicle, delivers the results to the ECU, improves air-fuel ratio (A/F) control, and exhaust gas purification rate to minimize the emission of harmful gases.
Air heater improves cold start-up performance and reduces white smoke and emission after start-up by heating the suction air of the direct injection diesel engine to assist combustion.
