Disclosed are an ignition timing control device and ignition timing control system capable of easily performing ignition timing control on an internal combustion engine so as to suppress the occurrence of engine knocking even in the case where the internal...

An apparatus and a method for controlling engine RPM (Revolutions Per Minute) for a construction machine are disclosed, which can compulsorily decrease the engine RPM when an air filter clogging signal is generated. The method for controlling engine RPM fo...

A control process for controlling an engine speed governor of an engine is provided. The process comprises the steps of calculating the current engine power (102) being developed by the engine, and determining an appropriate engine speed (104) for the curr...

To provide a control apparatus for a vehicle, capable of obtaining information indicating a relationship between an instruction value to be given to an actuator in accordance with a driving condition of a vehicle and a torque capacity of a clutch. A contro...

A current is supplied to a driving relay 27 that drives a bypass relay 24 when restarting an engine after idle reduction, and the current supply to the driving relay 27 is interrupted when the engine is started for the first time based on operation of a dr...

Provided is an engine rpm control device which gradually reduces the output speed of an engine drive object when reducing the engine rpm. The engine rpm control device (20) includes a target engine rpm correction means used upon detection of an engine fail...

An unstable idling state immediately after engine start is stabilized. The difference between a target idling engine speed corresponding to the cooling water temperature and an actual engine speed is integrated. The ignition timing is changed toward advanc...

The method involves enriching the fuel-air mixture in the start phase to ensure that the engine runs up, whereby fuel is deposited in the induction pipe as a wall film. A choke flap is opened to a constant setting in the start phase and in the post-start p...

There is described a control device (10) for controlling the speed ( omega eng) of an engine (1) of a vehicle (4), and having a tracer block (13) which receives a target engine speed ( omega targ) indicating the desired engine speed ( omega eng), and a max...

A method of controlling the operation of an engine fuel system including at least one fuel injector (14), a high pressure fuel pump (10) for delivering fuel to the injector (14) and a pressure sensor (18) arranged to provide an output signal indicative of ...
