ゼルエンジン。 An activation chamber that communicates with the main combustion chamber formed between the cylinder and the piston and faces the fuel injection nozzle is formed in the cylinder head, and the main combustion chamber and the activation chamber are connected in synchronization with engine rotation during the compression stroke. In a diesel engine, a diesel engine is provided with a ski valve that lifts so that a valve head portion is located in a communicating portion with the piston, and a protruding portion that has a gap in the communicating portion and can freely come and go is provided on the top surface of the piston, and the protruding portion Immediately before the top dead center of the piston enters the communication portion, lift control means is provided for lifting the squishing valve until the upper surface of the valve head portion of the squishing valve is seated on the top wall of the activation chamber. A diesel engine with an activation chamber.
