Engine control refers to the system that manages the performance of an engine in vehicles, ensuring it runs efficiently and meets emission standards. This system uses various sensors to monitor factors like air intake, fuel flow, and engine temperature. By processing this data, the engine control unit (ECU) adjusts parameters to optimize power output and fuel efficiency. The ECU is a crucial component in modern vehicles, often referred to as the brain of the engine. It communicates with other systems, such as the transmission and exhaust, to enhance overall vehicle performance. Proper engine control helps improve longevity and reduces environmental impact.
