摘要： PROBLEM TO BE SOLVED: To provide a piston structure for an internal combustion engine that can circulate oil to an oil return hole through a circumferential groove by scraping the oil on an inner wall of a cylinder bore in an entire circumference, and can prevent oil consumption from increasing.SOLUTION: The piston structure for the internal combustion engine configures a piston moving means for moving a piston 3 in a direction almost perpendicular to an axial line direction of the cylinder bore 2 so that an oil ring 15 in conjunction with rotation of a crankshaft 21 alternatively deflects to one side and the other side in the axial line direction of the crankshaft 21 to the cylinder bore 2. The piston moving means is composed of a pin groove 5a formed in a piston pin 5 and an alignment pin 23 provided in a small end portion 19 of a connecting rod 18 and fitting into the pin groove 5a.

摘要： PROBLEM TO BE SOLVED: To secure the reliability of oil properties detected by an oil property sensor, by suppressing dirt adhesion onto the oil-property sensor.
SOLUTION: This oil-property detection device 3 includes a fixed member 4, a stay 5, a float 6 and the oil property sensor 7. The stay 5 includes a connector part 51, fixed to a sidewall 2 of an oil pan 1 through a fixing member 4, a link 52 whose one end is rockably mounted on the connector part 51, and a sensor mounting part 53 mounted on the other end of the link 52 rockably. As for the sensor mounting part 53, a plurality of floats 6 are mounted on the upper part thereof, and the oil property sensor 7 is mounted on the lower part. In the oil-property sensor 7, a light is emitted from a light-emitting unit 71 traveling toward oil in an oil chamber 75, and the quantity of transmission light transmitted through the oil is detected by a light-receiving unit 72. In an operation part 10, a transmission rate through the oil is calculated based on the quantity of received light detected by the light receiver 72. An angle sensor for detecting a relative angle therebetween is provided on a connection part between the connector part 51 and the link 52.
