4 cycle engine |
| abstract |
(57) [Abstract] [Problem] To improve the output of the engine by reducing the compression height by thinning the top land, reducing the size and weight of the piston, suppressing the swing and reducing the sliding resistance, Provided is a four-stroke engine capable of improving emission and reducing noise. SOLUTION: In a four-stroke engine provided with a piston 27 having valve recesses 1a, 1b on an intake side and an exhaust side of a top surface 27a, at least a peripheral portion of the valve recess 1b on the exhaust side and a corner of the piston including a periphery of the top ring 5a. Was composed of a high-temperature high-strength material 3 made of a powder metal alloy. |
