エンジン。 An activation chamber is formed in the cylinder head that communicates with the main combustion chamber formed between the cylinder top surface and the piston top surface and faces the fuel injection nozzle. In a diesel engine equipped with a ski valve that lifts so that the valve head portion is located in the communication portion between the main combustion chamber and the activation chamber, the valve head portion is located in the communication portion between the main combustion chamber and the activation chamber. An air inflow passage is provided that allows air to flow in from the main combustion chamber along the wall surface of the activation chamber when the valve head is located in the communication area, and an air inflow passage is provided that allows air to flow in from the main combustion chamber along the wall surface of the activation chamber. Activation characterized in that a gap communicating with the activation chamber is formed sufficiently smaller than the cross-sectional area of the air inflow passage, and a fuel injection nozzle is made to face a wall surface of the activation chamber in the air inflow direction in the air inflow passage. Diesel engine with interior.
