There is disclosed a fuel adjustment device, including an ECU (10) and a catalyst (53) downstream oxygen sensor (SE4); ECU (10) controlling a fuel injection device (61) that causes an engine (5) to work; the catalyst downstream oxygen sensor (SE4) being pr...

An engine control unit (ECU) (10) of a common rail type fuel injection system of an internal combustion engine (1) determines that an abnormality failure of a fuel supply pump (4) is generated, if an abnormally high-pressure state in which a common rail pr...

The present invention relates to an engine protecting apparatus for preventing the inflow of moisture, which drops the RPM (revolutions per minute) of an engine by generating an RPM drop request signal when moisture drain does not occur, wherein a time is ...

An engine control unit (ECU) (10) of a common rail type fuel injection system of an internal combustion engine (1) determines that an abnormality failure of a fuel supply pump (4) is generated, if an abnormally high-pressure state in which a common rail pr...

In an internal combustion engine in which fuel injection valves are arranged on the upstream side and on the downstream side of the throttle valve respectively, process values such as the engine speed and the vehicle speed will be restricted at upper limit...

A method of operating a reciprocating internal combustion engine reduces friction power loss in an indicated power to increase net power and to reduce brake specific fuel consumption. A reciprocating internal combustion engine having an output characterist...

The invention relates to a control apparatus for a fuel priority type internal combustion engine (20), including a means of directly or indirectly detecting a variation in air density, for correcting a maximum value of the desired fuel volume on a basis of...

The control for an agricultural tractor power output Diesel engine has a sensor to produce a signal in dependence on the vehicle speed for the control. The control selectively produces an engine power increase in dependence on the vehicle speed. The sensor...
