摘要： In a structure or method of installing an injector in a delivery pipe of a common rail, the injector on which a seal member and a clip member are mounted is inserted into an interior of the delivery pipe in such a manner that the clip member comes in contact with the delivery pipe after the seal member comes in contact with an interior wall of the delivery pipe. This structure or method has an advantage of preventing the foreign material, which is a part of the protection layer peeled off from the delivery pipe due to contact between the clip member and the delivery pipe, from being lodged between the seal member and the inner wall of the delivery pipe.

摘要： An object of the present invention is to obtain a consistently stable needle lift damping effect in an injector 8b for fuel injection. In an injector 8b that relieves fuel pressure inside a pressure control chamber 37 and lifts a needle valve 36, there are provided a damper member 62 that is slidably mounted to the needle valve 36, a damping chamber 63 formed between the damper member 62 and the needle valve 36, a leak passage 64 for extracting and leaking out the fuel in the damping chamber 63, and a stopper member 41 to restrict the lift position of the damper member 62. Damping of the lift of the needle valve 36 is carried out by extracting and leaking out the fuel in the damping chamber 63 through the leak passage 64. The needle valve 36 functions as a guide for the damper member 62, and prevents vibration of the damper member 62, allowing a consistently stable damping effect to be obtained.

The fuel injector includes at least one capillary flow passage, the at least one capillary flow passage having an inlet end and an outlet end, a fluid control valve for placing the inlet end of the at least one capillary flow passage in fluid communication with the liquid fuel source and introducing the liquid fuel in a substantially liquid state, a heat source arranged along the at least one capillary flow passage, the heat source operable to heat the liquid fuel in the at least one capillary flow passage to a level sufficient to change at least a portion thereof from the liquid state to a vapor state and deliver a stream of substantially vaporized fuel from the outlet end of the at least one capillary flow passage and means for cleaning deposits formed during operation of the apparatus. The fuel injector is effective in reducing cold-start and warm-up emissions of an internal combustion engine.

摘要： An injector driving control apparatus operates with minimum power consumption, while ensuring linearity (proportionality between the current supply duration and fuel injection volume of the injector) in a wide fuel pressure range. A coil current feedback circuit is provided for controlling the current feedback duration according to the fuel pressure after applying the current at a boost voltage. This enables optimal control of the injector, and, hence, an improvement in the fuel injection volume characteristics (linearity) and a reduction in the heat generated in the injector driving control circuits.

摘要： A throttle opening range is divided into regions corresponding to the opening positions, and a deviation between an actual intake air suction state and a predetermined suction state provided for each of the divided regions is calculated. Intake system abnormality such as air cleaner clogging or intake pipe leakage is determined, if the deviation changes in a predetermined increasing or decreasing direction over a plurality of the divided regions. The air suction state may be represented by an intake pipe pressure or intake air flow quantity.

摘要： Experiment shows that a diesel engine discharges more smoke at a lower rate of increase of an engine rotation speed. Reducing an amount of fuel to inject into the engine when the rate of increase of the engine rotation speed is slow can prevent smoke generation. To be more specific, a controller (1) computes the rate of increase of the engine rotation speed by using signals from sensors that detect a vehicle condition. The controller (1) contains maps that indicate a correction coefficient corresponding to the rate of increase of the engine rotation speed. The controller (1) calculates the amount of fuel to inject based on the correction coefficient. Using the calculated amount of fuel, the smoke discharge from the diesel engine is suppressed.

摘要： Even if the engine is started from any crank angle position, it is possible to correctly determine the rotational direction of a crankshaft, so that fuel injection or ignition can be stopped when the crankshaft is rotating in the reverse direction. A measurement member has a plurality of angular position detection portions arranged at equal intervals in a circumferential direction of the crankshaft and a plurality of reference position detection portions at which a part of the angular position detection portions is missing. A crank angle sensor is arranged near the measurement member for generating a crank angle signal representative of the rotational position of the crankshaft. A period detector detects periods of pulses of the crank angle signal. A reference position determiner determines a plurality of reference positions based on the signal periods. A counter counts the pulses of the crank angle signal. A rotational direction determiner detects the rotational direction of the crankshaft from the number of pulses counted between a plurality of reference positions.
