摘要： The fuel injection pump comprises a cam ring (46) mounted for angular adjustment by means of a piston (50) to control injection timing. A fluid chamber (921 on one side of the piston (50) is in communication with a source of fluid under pressure correlated with engine speed and acting against the bias of a spring (80) arranged in a chamber (98) at the other side of the piston (50). The chamber (98) at the other side of the piston being also in communication with a fluid under pressure and a drainage passage (106) controlled by a valve (104) being provided to control release of fluid from the chamber (98). The valve (104) is actuable by a failsafe stepper motor (108) through a non-reversible drive in response to at least one set of continuous measurements of an operating parameter of an associated engine indicative of engine temperature, altitude, fuel density, or fuel injection angle.

摘要： A fuel injection detecting system is used with a diesel engine having a fuel injection nozzle, the nozzle including a movable member for effecting fuel injection into the engine when the valve member is displaced from its normal position and interrupting fuel injection when the valve member is returned to its normal position. The detecting system includes a sensor for sensing displacement of the valve member and generating a signal indicative thereof. A comparator is provided to compare the signal from the sensor with a reference signal and to generate a signal indicative of fuel injection via the nozzle. The detecting system also includes a device for preventing the fuel injection signal from including components unrelated to fuel injection via the nozzle. This device may disable the sensor for a predetermined period immediately after the first major displacement of the valve member. Alternatively, the device may adjust the reference voltage so as to hold the voltage thereof at a level exceeding that of all features of the sensor signal except the signal largest peak during each fuel injection.

摘要： A fuel injection control apparatus for an internal combustion engine for supplying an additional amount of fuel in addition to a basic amount of fuel when an acceleration condition is detected in accordance with a throttle opening change rate. The apparatus stops the injection of the additional amount of fuel when a deceleration state is detected in a state where both of the basic and additional amount of fuel are injected.

摘要： According to the present invention, control parameters for the amount of fuel to be injected and the fuel injection timing respectively are derived from the fuel injection command from an accelerator pedal and operation parameters fed back from an engine, and control quantities are calculated from the operation parameters for controlling actuators (11, 16) so that there are no differences between the actually controlled quantities fed back from the actuators (11, 16) and the calculated control quantities respectively.

摘要： A fuel metering system for a gas turbine engine with a low pressure drop fuel vaporizing system includes an engine driven centrifugal pump (10) supplied with fuel at a given absolute pressure (Pi) from a tank. The pump discharges fuel to a rapidly pulsed, solenoid operated ball valve (20) which functions as a metering valve in controlling flow to the engine. The solenoid of the metering valve receives periodic voltage pulses of appropriate width from an electronic control (24) which senses selected engine parameters and computes the required fuel flow and the pressure differential (Pr-Pp) across the metering valve. Since the pressure differential across the metering valve (20) increases with engine speed, favorable flow turndown ratios may be achieved without operating the metering valve at high or low values of duty cycle.

摘要： A method and apparatus for controlling fuel to be supplied from a motor-driven fuel pump to fuel injection valves of a fuel injected engine, the time period during which the fuel injection valves are kept open and the power duty cycle for driving the fuel pump motor are both calculated by a microcomputer responsive to one or more engine operating conditions. Reduced power consumption of the pump motor is achieved, thus resulting in reduction in the load applied to the battery and therefore improving the fuel consumption rate. The apparatus comprises an input unit, an injector drive unit, and a pump drive unit in addition to the microcomputer, and includes circuits for converting both the time period and the power duty cycle according to the battery voltage and the degree of engine acceleration.

摘要： An injection pump includes a rotor (10) having a central axial bore (48) and a radial bore (16) and rotated in relationship with an engine. A free piston (46) reciprocably inserted in the central axial bore (48) defines a first and second chamber (44, 50). The first chamber (44) includes a plurality of first radial passages (58-68) and a radial spill port (56) and communicates with the radial bore (16) and the second pressure chamber (50) includes a plurality of second radial passages (72) and a discharge passage (54). A pair of plungers (12, 14) which is disposed in the radial bore (16) is so constructed as to produce, in accordance with the revolution of the rotor (10), a compression period in which the liquid fuel is pressurized in the first pressure chamber (44) and pressurized fuel in the second pressure chamber (50) is supplied to the engine through the discharge passage (54), and a suction period in which the liquid fuel is supplied to the pressure chambers (44, 50).

Diese besteht aus einem mit der Düsennadel zusammenwirkenden Nadelhubindikator mit Steuerschaltung sowie einer daran angeschlossenen, ihrer seits mit einer Alarmeinrichtung und oder der Brennstoffab sperrvorrichtung verbundenen, elektronische Auswertor gane aufweisenden Überwachungseinrichtung. Die Überwa chungseinrichtung ist dabei in der Lage, praktisch alle an der Düsennadel und deren Bewegungsablauf möglicherweise entstehende, durch den Nadelhubindikator signalisierte Stö rungsfälle auszuwerten und im Störungsfalle ein Notstopp- Signal abzugeben, durch das entweder nur der oder die Zylin der mit dem eine defekte Düsennadel aufweisenden Ein spritzventil oder alle Zylinder der Brennkraftmaschine abschaltbar sind. Außerdem wird durch das Notstopp-Signal eine nachgeschaltete Alarmeinrichtung aktiviert, die exakt den Ort der Störung signalisiert und somit eine rasche Scha densbehebung vor Ort ermöglicht.

摘要： A method and a system for engine control are disclosed in which an engine control signal is generated on the basis of a signal produced at each moment from at least one sensor (24 or 27) for detecting the operating condition of the engine while being driven, said control signal being used for engine control. In order to attain the proper engine operating condition, the detection signal from the sensor is adjusted in advance, and data (QA I or Δθ) for correcting the sensor output is calculated from said adjustment value, said correction data being stored in a memory (122). While the engine is running, the detection signal from the sensor is corrected by the correction data stored in the memory, and this corrected detection signal is used to produce the control signal.
