  • High pressure fuel injection device for engine
    Patent number: 4969442
    Abstract: A high pressure fuel injection device including an accumulator type fuel injection nozzle for an internal combustion engine. High pressure fluid is delivered to the accumulator chamber by a reciprocating pump and the amount of fuel discharged is controlled by controlling the discharge pressure of the high pressure pump. This is done by varying the timing phasing of the pump.

  • Actuator for accumulator type fuel injection nozzle
    Patent number: 4964571
    Abstract: An accumulator type fuel injection nozzle including a resistor in the actuating electromagnet of the relief valve for controlling the operation of the valve. In the illustrated embodiment, there are provided two electromagnets, one of which opens the relief valve and the other of which closes the relief valve. In addition, a thermistor is provided in the circuit to the electromagnet so as to render the device substantially temperature insensitive.

  • Diesel engine
    Patent number: 4962736
    Abstract: A combustion chamber and method of operating a diesel engine to insure maximum air utilization. The engine has a main chamber and a subchamber that communicates with the main chamber through a communication passageway. Fuel injection into the subchamber is begun at a time when the throat area of the engine by which the main chamber communicates with the communication passageway is equivalent to approximately the effective flow area of the communication passageway so as to insure maximum air utilization.

  • Emission preventing system of evaporated fuel for internal combustion engine
    Patent number: 4395991
    Abstract: An internal combustion engine in which a fuel evaporated in a fuel tank is stored in a crankcase, including a system for preventing the evaporated fuel from being emitted into the atmosphere. The crankcase is in communication with an intake passage through a breather passage and with the atmosphere through an atmospheric vent. Change-over means provides communication between the crankcase and the intake passage while the engine is running, and vents the crankcase to the atmosphere when the engine is stopped.
