IPC: F02B21/02
Filed: 1992-02-04
Abstract: PURPOSE:To activate diffusive combustion in a main combustion chamber at the late stage of combustion and improve combustion efficiency by communicating an accumulator with the main combustion chamber, to which fuel is directly injected, via a restrictor and increasing or decreasing pressure in the accumulator later than that in the main combustion chamber. CONSTITUTION:In a diesel engine, the fuel is directly injected from a fuel injection nozzle 4 to a main combustion chamber 9. With the self-ignition of compressive heat, flame 10 surrounding injected fuel 9 occurs. In this case, a cylinder head 3 is provided with an accumulator 11. The accumulator 11 is communicated with the main combustion chamber 8 via a restrictor 12. Inner pressure P2 iut the accumulator 11 is increased or decreased later than inner pressure P1 in the main combustion chamber 8 due to distribution resistance of the restrictor 12. As a result, at the late stage of combustion, when the flame 10 surrounding the injected fuel 9 swirls, gas in the accumulator 11 is injected to the main combustion chamber 8 to give disturbance to gas in the main combustion chamber 8. It is thus possible to activate diffusive combustion and improve combustion efficiency.

Abstract: PURPOSE:To perform a phase lock-in operation at a high speed and also to improve the noise characteristic in a lock-in state by providing a resistor between a phase comparator and a loop filter and a means which short-circuits the resistor in response to a control signal. CONSTITUTION:A resistor R1 is connected to a phase comparator 13, and a switch SW1 is connected in parallel to the resistor R1.
