PURPOSE:To prevent the abnormal rise of the temperature in the combustion chamber of a diesel engine by delaying an injection timing as a first stage and reducing the quantity of injection as a second stage. CONSTITUTION:A temperature sensor 14 is fitted to a vortex flow chamber 8, and the pressure of fuel working to a timer is reduced and the injection timing is delayed as the first stage when the temperature exceeds critical temperature. The quantity of injection is reduced as the second stage when the temperature does not drop. Accordingly, the temperature of the combustion chamber can be lowered rapidly. |
