What is engine management?

Engine management refers to the systems and processes that control and optimize the performance, efficiency, and emissions of an engine, typically in vehicles. Modern engine management systems use electronic control units (ECUs) to monitor and adjust fuel injection, ignition timing, air intake, and exhaust output. These systems help ensure the engine runs smoothly, meets emission standards, and delivers the best possible fuel economy and performance. Technicians and engineers working in engine management design, maintain, and troubleshoot these complex systems.
