Novel pumping pressure four-stroke four-cylinder layering vortex combustion energy-saving gasoline engine

Abstract

A novel pumping pressure four-stroke four-cylinder layering vortex combustion energy-saving gasoline engine is especially suitable for big automobiles, small automobiles and motorcycles with large discharge capacity and characterized in that compared with the existing four-stroke upright four-cylinder gasoline engine, a first small piston pump (3) is additionally arranged on the rear sides of a first cylinder (42) and a second cylinder (41), and a second small piston pump (1) is additionally arranged on the rear sides of the third cylinder (39) and the fourth cylinder (26). The two small piston pumps (3 and 1) are arranged in reversed mode, and rear sides of the two small cylinders (88 and 97) and a fourth cylinder head (6) are of an integral structure. 12 valves are distributed in four combustion chambers (80, 76, 73 and 28), namely eight air inlet valves (71, 75, 78 and 83), four air outlet valves (82, 77, 74 and 29), and the twelve valves are arranged in upright mode. The engine achieves pumping pressure fuel oil vortex and air layering vortex combustion, and aeration quantity is further increased. The structure is simple, lubricating conditions are good, service life is long, a fuel oil thermal atomization effect is good, combustion is stable, work is reliable, the engine has large high-power output, fuel oil is saved by about 40%, and emission is reduced by 80%.

Description

Technical field [0001] The patent of the present invention relates to a four-stroke upright four-cylinder gasoline engine, in particular to a novel pump pressure four-stroke four-cylinder stratified vortex combustion energy-saving gasoline engine. Background technique [0002] The structure of the currently known four-stroke upright four-cylinder gasoline engine is composed of a crankshaft, a crankcase, a gearbox, a speed change mechanism, four chain rod assemblies, four piston assemblies, four cylinders, four cylinder heads, and a gas distribution mechanism. . The combustion chambers of currently known four-stroke upright four-cylinder gasoline engines adopt different valve quantity settings, and each combustion chamber of some engines has adopted two valves, three valves, four valves, and five valves. There is an engine combustion chamber that uses three valves, namely: two intake valves, one exhaust valve, and three valves in a radial setting in the combustion chamber. T...

Problems solved by technology

[0003] In order to overcome the technical problem of insufficient fuel saving in existing four-stroke upright four-cylinder gasoline engines, the patent of the present invention provides a new type of pump-pressed four-stroke four-cylinder stratified vortex combustion energy-saving gasoline engine. Moreover, the small crankshaft rotates 180° every time, so that the fuel in the small cylinder is forced into the platform fuel injection port of each cylinder, enters the large cylinder to rotate, and the pure air that has entered is layered and swirled for combustion, and the residual exhaust gas in each combustion chamber can be discharged from the engine. In addition, it also uses a quality rocker arm
