機関。 A fuel activation chamber in which a fuel injection valve is installed is formed in the cylinder head, and a squishing valve is provided passing through this fuel activation chamber, and the squishing valve connects the fuel activation chamber and the main combustion chamber. In a diesel engine with a fuel activation chamber configured to open and close a nozzle hole between the fuel activation chamber and the fuel activation chamber, the squish valve is configured to sit on a seating surface on the upper surface of the fuel activation chamber when the nozzle hole is opened. A diesel engine with a fuel activation chamber, characterized in that the distance between the lower edge of the squish valve and the upper edge of the injection hole in the seated state is set to about 1/4 of the diameter d of the injection hole.
