Control unit for synchronizing fuel injection in an internal combustion engine

An engine control unit 31 which synchronizes fuel injection of a cylinder 11 of an internal combustion engine, eg a diesel engine, comprises a port for receiving an in-cylinder pressure measurement, a port for receiving information, eg rotational angle, of a crankshaft 22, and a storage unit for storing the in-cylinder pressure measurement. Further, the engine control unit 31 comprises a determination unit for determining a run-time parameter of the cylinder 11 using the in-cylinder pressure measurement and the information of the crankshaft 22, and a cylinder control unit for controlling a run-time parameter unit using the determined run-time parameter. The run-time parameter can include the timing and amount of fuel injection, ignition timing and valve movement timing. Engine production cost can be reduced as a camshaft sensor is not required.
