Abstract

PURPOSE: To remove diesel knocking caused by the delayed ignition by providing an injection nozzle to inject fuel for pilot in a pre-combustion chamber and a main injection nozzle near the opened position of an injection hole from the pre-combustion chamber into a main combustion chamber.
CONSTITUTION: A pre-combustion chamber 2 is provided above a main combustion chamber 1, and connected to the main combustion chamber 1 through a passage 3 opened into the main combustion chamber 1 by an injection hole 4. An injection nozzle 5 is provided in the pre-combustion chamber 2 to inject fuel for pilot, while a main injection nozzle 6 is provided in the main combustion chamber 1 toward the circumference of the opened position of the injection hole 4. At this stage, the injection nozzle 5 is used to inject a part of fuel for pilot previously, and the main injection nozzle 6 is used to inject the main part of fuel of over 50% of all at a time point when a flame is jetted out from the pre-combustion chamber 2 into the main combustion chamber 1 together with unburned fuel by the ignition and combustion of the fuel which has been injected for pilot.
