PURPOSE:To adjust the injection timing properly, improve the fuel consumption thereof and reduce discharged poisonous substances in the exhaust gas thereof by a method wherein a hydraulic pressure in a hydraulic pressure chamber at the side of a driving piston driven by an engine is transmitted to the hydraulic pressure chamber at a timer piston side through a choke. CONSTITUTION:The driving piston 1,003 is driven through a revolving shaft 1,001, driven by the engine, and a fly weight 1,002 to increase the pressure of the hydraulic pressure chamber 1,005. When the engine is accelerated suddenly, a much amount of operating oil is sent from a pipe 1,006 to the hydraulic pressure chamber 1,021, the pressure of the hydraulic pressure chamber 1,021 is increased by the effect of the choke 1,025 and a driven piston 1,023 is driven to the left direction. The driven piston 1,023 drives the timer piston 13 to advance the injection timing. Thus, the injection timing may be adjusted properly, therefore, the fuel consumption may be improved and the discharged poisonous substances in the exhaust gas thereof may be reduced. |
