PURPOSE:To prevent explosive combustion in case of the starting of combustion by mounting two injectors, valves thereof are opened at supply pressure, one part thereof is lower than the maximum combustion pressure, the remainder thereof is higher than the maximum combustion pressure and which is lower than the maximum fuel supply pressure and which inject fuel. CONSTITUTION:When ignition operation is conducted, fuel is injected instantaneously to result in ignition combustion because the valve only of a fuel injector 14 is opened first under the state of low pressure. When the supply pressure of fuel rises close to the maximum value with slight time delay, the valve of a fuel injector 15 is opened, and fuel injection is started at the full flow rate. Since combustion is already started through fuel injection from the fuel injector 14 in a combustion chamber 1 at that time, ignition in case of the injection of the full flow rate is rapidly conducted, and a large amount of fuel not burnt is not stored in the combustion chamber 1. Accordingly, the generation of sudden explosive combustion can be prevented. |
