Abstract: This internal combustion engine includes a piston, an oil jet that operates at a predetermined operating pressure to supply oil to the piston, and a hydraulic controller provided upstream of an oil passage including the oil jet. The hydraulic controller includes a constantly opened first passage through which the oil having a pressure lower than the predetermined operating pressure is supplied to the oil jet, a second passage provided alongside of the first passage and being openable and closable, through which the oil having a pressure higher than the predetermined operating pressure is supplied to the oil jet in combination with the first passage in a state where the same is opened, and an opening-closing control portion that controls the second passage to be in an open state when actuating the oil jet, and controls the second passage to be in a closed state when stopping actuating the oil jet.

Abstract: The present invention refers to a method for controlling a piston cooling circuit of an internal combustion engine wherein said circuit comprises at least a circulation pump and means for emitting cooling oil connected to the delivery of the pump. According to the method, said pistons are cooled by a jet generated by said emitting means only during the upward stroke of said pistons from the bottom dead center to the top dead center.

Abstract: Embodiments for a lubrication system for an internal combustion engine are provided. In one example, a lubrication system for an internal combustion engine comprises a lubricant circuit, a radiator for cooling the lubricant, a heat accumulator arranged upstream of the engine for warming up the lubricant, the heat accumulator connected in parallel to the radiator, and a valve for switching over the lubricant circuit between the radiator and the heat accumulator. In this way, the oil may be rapidly heated during cold engine start conditions.

Abstract: In a two-stroke engine including a scavenging port (43b) having an open end (42d) opening out in a side wall of the cylinder bore (3a) and communicating with a crank chamber (2a), the open end being configured to be closed and opened by the piston (22), a fuel injection device (71) is mounted on the engine main body so as to inject fuel onto a back side of the piston and/or a part of the side wall of the cylinder bore located under the piston via the open end of the scavenging port or via the open lower end of the cylinder bore. The fuel deposited on the surfaces of the piston and the cylinder inner wall promotes the cooling of such parts.
