摘要： An apparatus for controlling the timing of fuel injection into a diesel engine, including means for computing a target time at which injection should occur and means for sensing when injection actually occurs, with respect to a reference crankshaft position, feedback control means for adjusting the actual injection time to bring this into coincidence with the target injection time, means for sensing when firing of fuel within an engine cylinder actually occurs and for computing a target firing time based on the current operating status of the engine. A compensation factor is computed based on the difference between the actual and target firing times, and is utilized to modify the actual fuel injection time such as to bring the actual and target firing times into coincidence. Means are included for judging whether the engine operating status will permit reliable firing time data to be acquired, and for selectively enabling and inhibiting computation of successive new values of compensation factor based on this judgement.

摘要： In a diesel engine controlling system having a fuel injection pump, a fuel injection timing adjusting device is controlled by a drive pulse signal whose duty cycle is controlled by a microcomputer. The duty cycle is determined such that a basic duty cycle obtained by using engine rotational speed and injection quantity, is modified or corrected by way of a correction factor and a forecast correction factor. The-first mentioned correction factor comprises an integration component and a proportional component both derived from the difference between a measured fuel injection or ignition timing and a desired or reference fuel injection or ignition timing, which is calculated by using the engine rotational speed and the injection quantity. The forecast correction factor corresponds to a differential value of the basic duty cycle or the desired fuel injection or ignition timing. In order to detect the fuel injection or ignition timing a timing detector is employed, where the state of an output signal from the detector is monitored to prohibit calculation of the difference or error, thereby correcting the basic duty cycle by only the forecast correction factor when the detector is in abnormal condition.

摘要： A fuel injection arrangement for a diesel engine. An overflow passage for high pressure fuel is provided in the engine's fuel injection pump. A solenoid valve is disposed in the overflow passage for controlling the fuel injection amount through its on-off operation. The time when the fuel injection pump starts injecting fuel is detected by an injection start detector. To this injection starting time point is added a target injection period to determine an injection end time. At this injection end time the solenoid valve is opened to discontinue the fuel injection. The target injection period is determined according to operating conditions of the engine. Since this apparatus detects the actual injection start point and controls the injection period on the basis of the result of the detection, the fuel injection amount can be controlled extremely accurately.

摘要： The intake pressure and temperature of a Diesel engine equipped with a supercharger are sensed and the sensed intake pressure value is divided by the sensed intake temperature value to obtain an intake density. A value indicative of the intake density is divided by a value indicative of the air-excess ratio computed in accordance with the operating condition of the engine producing a smoke-limit injection amount. The smoke-limit injection amount is compared with the injection amount corresponding to a part-load condition of the engine and the smaller one of the values is applied to a linear solenoid for controlling the fuel injection amount adjusting member in the fuel injection pump of the engine.

摘要： An optimum control method for internal combustion engines uses the values of an engine control variable, such as engine timing, which are arranged in a map and stored in a memory. During normal operation, the engine is operated in accordance with one of the mapped engine control variable values related to engine operating conditions. During a fuel consumption minimization operation, the mapped engine control variable value is changed by an incremented amount to operate the engine therewith, and the mapped engine control variable value is replaced by the changed engine control variable value, if it is detected that the change by the incremented amount is in a direction to reduce the fuel consumption rate of the engine. This optimum engine control method can compensate for changes in the characteristics of engines caused during the manufacture or caused by changes over time during their operation, thereby ensuring the operation of an engine at a minimum rate of fuel consumption.
