摘要： PURPOSE:To simplify the processing of injection quantity control, by storing the period from a reference time to the time when an overflow solenoid valve is opened by dividing the period into a pre-stroke period when fuel is not injected substantially and a period when fuel is injected actually. CONSTITUTION:Processing of interruption is started when a signal is furnished from a pump bottom dead point sensor 13 to an ECU9 during operation of an engine. That is, a solenoid valve 8 is at first de-energized to stop overflow of high-pressure fuel in a pump chamber 5, and then a time thetae corresponding to the injection quantity of fuel is searched from a prepared map on the basis of the output signals of an engine-speed sensor 10, a sensor 11 for detecting the position of an accelerator pedal, an idle-position sensor 12, sensors 14, 15 for detecting the ambient pressure and temperature of the engine, etc., and the time thetae is corrected appropriately according to the temperature, pressure, etc. Then, by reading a pre-stroke period thetaR and adding thetaethetaR to it, the total time (crank angle) is detected and the solenoid valve 8 is energized when the period from the time when the solenoid valve 8 is de-energized becomes equal to said total time.

摘要： In a diesel engine comprising a fuel injection pump which supplies pressurized fuel by a plunger to a fuel injection nozzle, fuel properties such as fuel viscosity are determined. A fuel supply start timing by the plunger and fuel injection start timing by the fuel injection nozzle are respectively detected, a difference between them is computed as an injection retardation period, and the fuel viscosity is determined based on the injection retardation period. A fuel injection amount, injection timing or exhaust recirculation amount are corrected based on the determined fuel viscosity, therefore errors in their control do not arise due to differences of fuel viscosity.

摘要： An apparatus for controlling an exhaust gas is disclosed. A recirculation device (40) includes an EGR passage (41) connecting an air exhaust passage (22) with an air intake passage (16) to control the exhaust gas flowing to the intake passage (16) by opening or cloning an EGR valve (42) in the EGR passage (41) to suppress smoke caused by the exhaust gas. The apparatus includes a valve (25) disposed in the intake passage (16). The valve (25) controls the air flowing to the engine (11). The apparatus includes a speed sensor (56), a pressure sensor (59) and a gas pedal sensor (61) for detecting a driving status of the engine (11). The apparatus also includes an electronic control unit (39) for computing a target amount of the air to be supplied to the engine (11) based on the detected driving status of the engine (11). The apparatus further includes a vacuum pump (32) for controlling the intake restriction valve (25) to adjust the amount of the air based on the computed target amount. The electrical control unit (39) determines generation of the smoke based on the detected driving status of the engine (11) and corrects the amount of the air supplied to the engine (11). The electrical control unit (39) also controls the intake restriction valve (25) to increase the amount of the air with respect to the computed target amount for a predetermined time period after determining the generation of the smoke.
