Three-circle concentric eccentric rotor homogeneous charge compression ignition engine

Abstract

The invention relates to a three-circle concentric eccentric rotor homogeneous charge compression ignition engine. The internal combustion engine structurally comprises a cylinder barrel, a piston, aneccentric rotor, a sealing roller, a sealing roller fulcrum shaft, a combustion chamber body, only one high-pressure air valve in an air distribution mechanism and a gear transmission system, round grooves are formed in the inner sides of the two cylinder barrel covers, the two grooves are concentric with the inner wall of the cylinder barrel, the piston is installed in the eccentric rotor groove, the two rolling bearings on the piston roll in the round grooves of the two cylinder covers, and therefore the piston and the cylinder barrel are separated from each other. (the eccentric rotor andthe piston slide back and forth by 60 mm every 360 DEG C). By means of the homogeneous charge compression ignition technology, the fuel heat efficiency can be improved by 1.5 times or above compared with 32.3% of fuel heat efficiency of a reciprocating gasoline engine on the market at present, and meanwhile NOx content is reduced by 95%.

Description

technical field [0001] The invention relates to a three-circle concentric eccentric rotor homogeneous compression ignition engine. Background technique [0002] The piston reciprocating gasoline engine is thrown away from the exhaust gas when the exhaust gas pressure is still high during work, which wastes a lot of energy in the exhaust gas discharge and produces very loud noises. The mechanical working pressure angle of the reciprocating engine in the mutual conversion from rotary motion to linear motion is very large, and from a mechanical point of view, the loss is quite large. (According to page 54 of the book "Automotive Engine Design" [by W.H. Krauss (USA)], "Mechanical friction loss accounts for 10% of the total energy of the fuel"). The reciprocating engine can release the most heat energy only after the combustible mixture reaches homogeneity and then is compressed and ignited to achieve energy saving and environmental protection; however, the gasoline engine only ...

AI Technical Summary

Problems solved by technology

The reciprocating engine can release the most heat energy only after the combustible mixture reaches homogeneity and then is compressed and ignited, which realizes energy saving and environmental protection; however, the gasoline engine only completes the mixing of oil and gas during suction and pressure, and cannot achieve homogeneity. The combustion is even less homogeneous, and the exhaust gas contains a lot of carbon particles that are discharged into the atmosphere
