摘要： In order to perform fuel injection control for a diesel engine, data read by an ignition timing data reading means is compared with a reference data to calculate an ignition timing difference. The ignition timing error is compared with a predetermined threshold value to decide whether or not the ignition timing difference exceeds the predetermined threshold value. A pilot injection timing correction data is generated in accordance with the result of the decision. The pilot injection timing control data is instructed in accordance with the pilot injection timing correction data, and pilot injection timing control is performed in accordance with the pilot injection timing control instruction. A feedback control of a signal based on an output from the ignition timing detector is used for control of a pilot injection timing, so that ignition at a desired ignition timing is performed.

摘要： An internal combustion engine has an evaporated fuel purge system for directly feeding evaporated fuel of a fuel tank into an intake pipe of the engine during the engine is running. This system comprises a purge control valve for opening or closing a flow line which connects an upper space of the fuel tank with the intake pipe, a controller for controlling the operation of the valve, a throttle section formed in series with the purge control valve, and pressure and temperature sensors which are located on the upstream side of the throttle section for detecting a pressure and a temperature of the evaporated fuel. When a value detected by the pressure sensor exceeds a predetermined value of pressure for providing a critical pressure ratio at which a flow rate of the evaporated fuel at the throttle section substantially equals to a sonic velocity, the controller opens the purge control valve to cause a purged flow of the evaporated fuel whose flow rate is constant. Simultaneously, the controller calculates a purged flow rate of the evaporated fuel from the detected values of the pressure and temperature sensors and a time period during which the purge control valve is opened. On the basis of the calculated purged flow rate, a reduction correction is made to an amount of the fuel to be supplied to the engine in order to maintain an air-fuel ratio in the optimum condition. The calculated purged flow rate may be indicated.

摘要： A fuel injection system in which a fuel injector having a fuel pressure control chamber formed therein to create a pressure which forces a needle valve in the closing direction to open and close the nozzle hole, an accumulator to retain fuel discharged from the nozzle hole, and a fuel injector provided at each of the cylinders of the engine, are connected to the fuel injection pump by a single piping system without utilizing a special distribution mechanism. The volume of the fuel pressure control chamber in the fuel injector can be changed by a piezo-actuator. A check valve is provided at a half way point of the piping which leads the fuel fed under pressure from the fuel injection pump to the fuel injector into the fuel pressure control chamber and the accumulator, so that the fuel is fed through the check valve into the fuel pressure control chamber and the accumulator.

摘要： A pump including a plunger slidably disposed in a pump body, a transmitting member connected to the plunger, a coil spring which urges the plunger, and a cam urging the plunger against the coil spring. The plunger defines a pump chamber in the pump body. The coil spring urges the plunger in a direction such that the plunger contracts the pump chamber. The cam rotates in synchronization with the rotation of the engine and engages with the transmitting member for part of the cycle of the rotation of the engine so that the plunger increases the volume of the pump chamber. The cam releases the plunger in the remaining cycle of the rotation of the engine to allow the coil spring to urge the plunger so that the plunger displaces in a direction to reduce the volume of the pump chamber.

摘要： A piezoelectric fuel injector for use in fuel injection systems of spark-ignition engines is provided with a normally closed valve assembly in the form of a reed valve. The valve assembly includes a valve plate having one or more outlet ports having an overall cross-sectional flow area sufficient to ensure an unobstructed flow path therethrough. The valve assembly also includes a generally flat, thin, resilient closure member cooperating with the valve set of the valve plate. The pressure wave created in the fuel in the pumping chamber upon excitation of the piezoelectric actuator propagates into the outlet ports to directly reach the thin closure member, which readily resiliently yields to permit a desired amount of fuel to be injected into the engine cylinders. The fuel injector is particularly suitable to be operated by a high-frequency drive signal in order to ensure precise metering of fuel quantity over a wide range of engine operating conditions.

摘要： A fuel injector for an internal combustion engine, the injector being actuated by a piezoelectric actuator. The piezoelectric actuator operates a piston, which changes the volume of a pump chamber formed between the piston and a nozzle needle. The nozzle needle moves up and down in response to a pressure in the pump chamber to open and close a port for injecting fuel. The piston is pressed toward the pump chamber by a fluidic force or a spring force and so on.
