Novel four-stroke layered double-swirling combustion energy-saving internal-combustion engine with new air distribution mechanism

Abstract

The invention relates to a four-stroke layered double-swirling combustion energy-saving internal-combustion engine with a new air distribution mechanism, and is particularly suitable for various internal-combustion engines for seas, land and space. A cylinder (28) and a cylinder oil nozzle gasket (32) are arranged on a crankcase (85) of a conventional four-stroke single-cylinder gasoline rod ejector, the new air distribution mechanism is arranged in a small cylinder head (12), and a small cylinder (40) is arranged inversely. The front of the wall of the small cylinder (40) is provided with two ports (34), and a small piston (38) slides up and down to suck air and exhaust air. The sucked air rotationally enters along the walls of the big cylinder (28) and the small cylinder (40), the inlet fuel oil rotationally enters, the big and the small pistons apply work at the same time, and the exhausted air pushes a suction-exhaust turbine (51) to apply first work. The internal-combustion engine has the advantages of simple structure, good lubricating condition, long service life, stable work, high revolution rate and no noise; and the engine realizes layered double-swirling combustion of the fuel oil swirled in the middle of an hot air interlayer, and realizes three-time work application in one-time combustion, so that the engine has higher high-power output, saves the fuel oil by about 50 percent and reduces the emission by 85 percent.

Description

New four-stroke new gas valve mechanism stratified double-swirl combustion energy-saving internal combustion engine Technical field The patent of the present invention relates to a four-stroke internal combustion engine, in particular to a novel four-stroke new valve mechanism layered double-swirl combustion energy-saving internal combustion engine. Background technique The structure of present known four-stroke single-cylinder gasoline engine is made up of crankshaft gearbox, crankshaft, speed change mechanism, chain rod assembly, piston assembly, cylinder, cylinder head, valve train etc. At present, the valve trains of domestic four-stroke single-cylinder internal combustion engines are composed of camshafts, rocker arms, rocker shafts, intake valves, exhaust valves, valve seat rings, and valve springs. These parts are the indispensable moving parts of the current four-stroke engine, and they are also the mature gas distribution mechanism of the four-stroke engine. It h...

Problems solved by technology

In order to overcome the trouble caused by high-temperature vibration, deformation and noise of the existing four-stroke single-cylinder internal combustion engine valve train parts in China, and the technical problem of insufficient fuel saving, the patent of the present invention provides a new four-stroke new valve train layered double The vortex combustion energy-saving internal combustion engine is a new type of four-stroke new gas distribution mechanism layered double vortex combustion energy-saving internal combustion engine. Not only are there two ports in front of the small cylinder wall of the new gas distribution mechanism, the two ports are advanced by the small piston sliding up and down. Air, exhaust, and the residual exhaust gas of the combustion chamber is blown out of the machine, and the intake and exhaust passages are very smooth, which can reduce the suction loss of large and small pistons, and the resistance of pushing exhaust gas, and the wind from supercharging It can cool the intake and exhaust turbines, and the hot air entering the two ports is rotated into the cylinder, and the fuel enters the cylinder through the platform fuel injection port so that it rotates into the cylinder
