Four-stroke internal combustion engine bidirectional air inlet method and device thereof

Abstract

The invention discloses a four-stroke internal combustion engine bidirectional air inlet method and a device. The device comprises a cylinder provided with a cylinder chamber which leads gas in to carry out combustion and explosion; the cylinder is provided with an air inlet valve and an exhaust valve which are respectively connected with the cylinder chamber; a crank shaft chamber is communicated with the cylinder chamber and is provided with a crank shaft and a connecting rod which are connected with each other; the connecting rod is connected with a piston which moves in the cylinder chamber; the crank shaft chamber is provided with an air inlet port of the cylinder adjacent to the cylinder chamber; a first air inlet manifold is communicated with the air inlet valve; an exhaust manifold is communicated with the exhaust valve; a second air inlet manifold is connected with the crank shaft chamber; so that the four-stroke internal combustion engine can implement air inlet stroke, secondary air inlet, compression stroke, power stroke, exhaustion and blow down and exhaustion stroke in a circulating manner so as to overcome the defects that waste gas exists in the exhaustion stroke of the traditional four-stroke internal combustion engine and the air inlet stroke can not reach 100% of volume efficiency, thereby efficiently improving power and performance of the four-stroke internal combustion engine, reducing pollution emission, and achieving desired operation effect.

Description

technical field [0001] The present invention relates to a structure of a four-stroke internal combustion engine, in particular to a newly designed intake stroke and exhaust stroke, which can effectively improve the power and performance of the four-stroke internal combustion engine, so that the four-stroke internal combustion engine can accelerate the discharge of the cylinder after the power stroke. Method and device for exhausting gas inside a chamber. Background technique [0002] Due to the preciousness and shortage of energy, the current international research on high-efficiency energy utilization and how to generate higher power internal combustion engine (engine) performance has always been an important topic for continuous research and development breakthroughs. The basic structure of the existing four-stroke internal combustion engine (engine) is as follows: Figure 12 Shown, it comprises a cylinder 80, and this cylinder 80 has a cylinder chamber 81 and is connected...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: after the explosive stroke and the exhaust stroke of the existing four-stroke internal combustion engine, the exhaust gas residue cannot be effectively discharged, which interferes with the combustion of the next cycle, thereby reducing the due intake volumetric efficiency and thermal efficiency; The gas in the intake stroke cannot achieve 100% volumetric efficiency of the intake
