Moottorinohjaus, often translated as engine control, refers to the system responsible for managing and optimizing the operation of an internal combustion engine. This system, commonly known as the Engine Control Unit (ECU) or Powertrain Control Module (PCM), is a sophisticated computer that receives data from various sensors throughout the engine and vehicle. These sensors monitor parameters such as engine speed, air intake temperature and pressure, throttle position, oxygen levels in the exhaust, and coolant temperature.

Based on this sensor data, the ECU calculates and executes commands to various actuators. The primary functions of moottorinohjaus include controlling fuel injection timing and quantity, ignition timing, idle speed, and emissions control. By precisely managing these aspects, the system aims to achieve optimal engine performance, fuel efficiency, and reduced emissions. Modern engine control systems are highly complex, often incorporating strategies for turbocharger boost control, variable valve timing, and even integration with other vehicle systems like the transmission and anti-lock braking system. The continuous advancement in sensor technology, processing power, and software algorithms has led to increasingly sophisticated and efficient engine control solutions.
