A diesel engine having a piston chamber and a combustion chamber communicating through a port with the piston chamber; a temperature sensing means which is responsive to temperature in the combustion chamber and which controls a valve to permit fuel flow to the combustion chamber only when the temperature in the combustion chamber has reached a predetermined level to support combustion; a supercharger responsive to engine speed and arranged to deliver pressurized air to the combustion chamber when the engine is operating; and a protrusion mounted on the piston and arranged to extend into the port so as to form an annular passageway through which air blows from the piston chamber into the combustion chamber to cause better mixing of fuel and air in the combustion chamber.
