Abstract: An internal-combustion engine includes a cylinder, a piston, a spark plug, and a fuel injection device. The piston includes a top surface, a guiding protrusion, and a cavity. The cavity is provided at a position closer to the fuel injection device than the guiding protrusion when viewed from above the top surface of the piston. The guiding protrusion includes a guiding surface to guide the fuel mist toward the spark plug when the fuel mist is injected from the fuel injection device at a first predetermined timing in a compression stroke. The cavity includes a guiding wall portion to guide the fuel mist toward the spark plug when the fuel mist is injected from the fuel injection device at a timing in the compression stroke between the first predetermined timing and a second predetermined timing.

Abstract: A control device for an internal combustion engine is provided which enables control of dilution of oil by fuel and water drops, i.e., control of the amount of so-called oil dilution. The control device for an internal combustion engine that is lubricated or cooled by oil includes: a variable displacement oil pump capable of varying the amount of discharge of the oil; an air-fuel ratio sensor for sensing an air-fuel ratio of the internal combustion engine; and an ECU for controlling the amount of discharge of the variable displacement oil pump. The ECU controls the amount of discharge of the variable displacement oil pump, based on the air-fuel ratio sensed by the air-fuel ratio sensor.

Abstract: An internal combustion engine cooling system, including: an internal combustion engine; a cooling circuit in which cooling fluid for cooling the internal combustion engine is circulated; a radiator for cooling the cooling fluid; a radiator circuit that branches from the cooling circuit to guide the cooling fluid to the radiator and return the cooling fluid having passed the radiator to the cooling circuit; a thermostat that is provided in a portion where the cooling circuit and the radiator circuit are connected to each other and that opens and closes a path between cooling circuit and the radiator circuit; a heater for heating the thermostat; and a control device for controlling the heater.
