Novel four-stroke four-cylinder layered dual-vortex combustion energy-saving internal combustion engine with new gas distribution mechanism

Abstract

The invention provides a novel four-stroke four-cylinder layered dual-vortex combustion energy-saving internal combustion engine with a new gas distribution mechanism. In the internal combustion engine, four cylinder nozzle gaskets (14) and four small cylinder heads (13) with the new gas distribution mechanisms are arranged on four cylinders (28) of the conventional four-stroke vertical four-cylinder double overhead camshaft gasoline engine, and four small cylinders (37) are arranged inversely; two ports (35) are arranged in the front of the wall of each small cylinder (37); gas enters and is exhausted by up and down sliding of a small piston (39); and when big and small pistons (32, 45, 48, 52, 39) apply work simultaneously, gas exhaust is to push each small piston (39) and intake and exhaust turbines (66, 69, 73, 77) to apply work. The internal combustion engine has the advantages of simple structure, good lubricating condition, stable work, realizes that fuel vortex performs layered dual-vortex combustion in hot air interlayer, thereby having larger high-power output, saving fuel by about 50 percent, and reducing emission by 85 percent.

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 four-stroke four-cylinder stratified double-swirl combustion energy-saving internal combustion engine with a new valve mechanism. Background technique [0002] The structure of present known four-stroke four-cylinder gasoline engine is made up of crankshaft, crankcase, gearbox, speed change mechanism, four chain rod assemblies, four piston assemblies, four cylinders, four cylinder heads, valve train etc. At present, the valve trains of domestic four-stroke four-cylinder internal combustion engines all adopt camshafts, rocker arms, rocker shafts, intake valves, exhaust valves, valve seat rings, valve springs, etc. to form. 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 has its disadvantages, such as when the en...

Problems solved by technology

[0003]In order to overcome the troubles caused by high-temperature vibration, deformation and noise of the parts of the existing four-stroke four-cylinder internal combustion engine valve mechanism in China, and the technical problem of insufficient fuel saving, The patent of the present invention provides a new four-stroke new gas distribution mechanism four-cylinder layered double-swirl combustion energy-saving internal combustion engine, the new four-stroke new gas distribution mechanism four-cylinder layered double-swirl combustion energy-saving internal combustion There are two ports in front of each small cylinder wall, and the two ports slide up and down by the small piston for intake and exhaust, and the residual exhaust gas of each combustion chamber can be blown out of the machine, in the intake port and exhaust port It is very smooth, which can reduce the suction loss of the large and small pistons and the resistance of pushing the exhaust gas. The wind from the supercharger can cool the intake and exhaust turbines, and the hot air entering the two ports is rotated into the cylinder, and the fuel enters through the platform fuel injection port. The cylinder is entered by rotation, and the supercharged engine fuel swirl is layered in the middle of the hot air swirl interlayer for double swirl combustion. The combustion pressure pushes the large and small pistons to do work at the same time, and the exhaust pushes the small piston and the intake and exhaust turbines to do work once respectively. Stroke once, burn four times to do work
