Question about 1996 Mercedes-Benz C-Class
An engine control unit (ECU) is an electronic control unit which controls various aspects of an internal combustion engine's
operation. The simplest ECUs control only the quantity of fuel injected
into each cylinder each engine cycle. More advanced ECUs found on most
modern cars also control the ignition timing, variable valve timing (VVT), the level of boost maintained by the turbocharger (in turbocharged cars), and other peripherals.
ECUs determine the quantity of fuel, ignition timing and other parameters by monitoring the engine through sensors. These can include, MAP sensor, throttle position sensor, air temperature sensor, oxygen sensor and many others. Often this monitoring and control is done using a control loop (such as a PID controller).
Before ECUs, most engine parameters were fixed. The quantity of fuel per cylinder per engine cycle was determined by a carburetor or injector pump.
