A fuel injection control device of an engine is disclosed, that is provided with a fuel injection valve configured to inject a fuel according to a target pulse width into an intake passage, an intake flow rate detection unit arranged to detect a flow rate ...

To provide a fuel injection amount calculation method and a fuel injection controlling apparatus wherein, even if a displacement appears at opening and closing timings of valves due to an assembly error or time-dependent variation of the tappet clearance, ...

A control unit (7) calculates a quantity of air that is taken into an engine (2) from an output current from an air flow meter (14) that is located downstream from a throttle valve (12). The control unit (7) then determines the quantity of fuel to be injec...

An engine control system (1) measures an amount of air sucked by an engine (2) based on the output of an air flow meter (14) provided in an air intake passage (4), on the downstream side of a throttle valve (12), calculates an injection amount of fuel base...

A control apparatus is for an engine (1) of a direct cylinder fuel-injection type that directly injects a fuel in a combustion chamber of a cylinder. The control apparatus includes an air flow meter (28) which is positioned downstream from a throttle valve...

A control unit (7) calculates a quantity of air that is taken into an engine (2) from an output current from an air flow meter (14) that is located downstream from a throttle valve (12). The control unit (7) then determines the quantity of fuel to be injec...

The method involves calculating the flow of air in an engine (1) and flow of input air. The flow of the air in the engine is calculated from engine speed and the temperature of the air in an intake manifold (3). The mass of air in an intake circuit is calc...
