。 The engine is equipped with an oil injection device capable of injecting oil, and the oil injection device includes a first oil nozzle directed toward the inner wall surface of the cylinder bore, and a second oil nozzle directed toward the back side of the piston. The inside of the oil injection device is equipped with a nozzle that switches the flow of oil according to the oil pressure, so that when the oil pressure is low, the first nozzle is installed.
The piston is characterized in that it has a built-in oil switching mechanism so that oil is injected only from the second oil nozzle, and when the oil pressure is high, the oil is injected from at least the second oil nozzle. Cooling and cylinder bore lubrication system.
