A fuel injection system for an engine, the fuel injection system includes injectors (20, 30) and an electronic control unit (50). The injectors include needle valves (36); and the ECU is configured to: (i) execute partial lift injection and full lift injec...

The invention, while reducing noise, suppresses a load increase in a processor and a delay in drive control. An engine control unit includes a processor, a driving circuit including a switching element to drive a load such as a fuel injector and an ignitio...

When the rotational speed of the diesel engine 1 exceeds the reference rotational speed, the fuel injection amount calculation processing is not completed at the first crank angle. Thus, the fuel injection amount calculation processing is interrupted and t...

A sensor device includes a failure diagnosing circuit configured to determined if a driving circuit, a detecting circuit or a processing circuit is normal or abnormal. An output circuit correlates the failure detection signal with the sense signal supplied...

A sensor device includes a time point determining part that determines time point information, and adds the time point information to the output supplied from a part subjected to failure diagnosis and related to generation of a failure detection signal, an...

A real-time control system for executing exactly a cyclic task, preventing a delay of the processing start time due to accumulation of a plurality of overhead times, thereby executing control enabling a more detailed response and control enabling a quick a...

The method involves assigning an actuator to each cylinder of an internal combustion engine for injecting fuel into the cylinder. Time of pre-injection caused by the actuator is simultaneously programmed with main injection depending on number of revolutio...

ÄProblemÜ To provide an engine control unit which can solve the problem of current leakage from an ignition system or the like due to attachment of water drops or the like when washing a vehicle. ÄMeans for ResolutionÜ An power circuit (110) receiving ...
