ENERGY-SAVING IC ENGINE

The utility model discloses an energy saving inner combustion engine using gasoline, diesel oil or kerosene. The utility model is arranged in a combustion chamber and other limiting surfaces contacting high-temperature gas and coated or inlaid with high-temperature resistant ceramic or an alloy heat insulating layer. The piston compression ratio is improved to 1: 20 (suction stroke) and 1: 30 to 50 (application work stroke). A crank is arranged on the size of the 3, 4 quadrants of a cylinder centerline in biasing. Meanwhile, a manual control mechanism used for adjusting the oil supply angle is also provided. The thermal transmission loss, the exhaust thermal loss and the piston sideways frictional loss are greatly reduced and the best combustion condition of the fuel is provided. The total thermal efficiency of the inner combustion engine can be improved to 50% to 60% in order to save the fuel energy resource. Various fuel oil can be used.
