Embodiment approach

[0045] Compression work independent chamber reciprocating four-stroke engine contains at least one set of compression chamber and work chamber, and engines with more than four cylinders are composed of half sets of compression chambers and work chambers. And the engine that contains a group of compression chamber and work chamber contains two cylinders and existing reciprocating piston type four-stroke two-cylinder engine is structurally similar, just take the engine that contains a group of compression chamber and work chamber as example to illustrate embodiment below. Engines with more than four cylinders consist of the following units with half the number of cylinders.

[0046] As shown in Figure 1 and Figure 2:

[0047]The left part of the cylinder head body (1) forms a compression chamber (23) with the compression cylinder liner (19) and the compression piston (20), and the right part of the cylinder head body (1) forms a compression chamber (23) with the working cylinder...

Abstract

Two adjacent combustion chambers of existing four-stroke engine, one is only used for inspiration to compress, another is only used for expansion apply work to exhaust, the cylinder cover for compressing is not provided with an exhaust fungus valve and an exhaust passage for exhausting waste gas of the existing engine, the cylinder cover for apply work is not provided with an air intake fungus valve and an air intake channel for snifting of the existing engine, a channel is on the cylinder cover to communicate two cylinders, and is provided with a one way air valve for draining compressed gas into the channel on cylinder end for compressing, and is provided with an air valve with certain time obstruct channel closing to the cylinder end for apply work, catalysts are coated on the channel wall of the cylinder end for apply work or a heat accumulator is provided in the channel. The engine adopts catalysis or heat accumulation ignition, the combustion is completely exhausted, the structure is more simple than that of the existing reciprocating type four-stroke engine, the weight is lost and the efficiency is improved to realize that the expansion volume is larger than the compression volume.

Description

Technical field: [0001] The engine belongs to a four-stroke reciprocating piston internal combustion engine. Background technique: [0002] In 1883, Gottlieb Daimler made the first four-stroke reciprocating piston gasoline engine, and in 1897 Diesel first made a diesel engine. Existing four-stroke reciprocating piston engine is to complete the air intake, compression, combustion expansion work, and exhaust cycle of the engine in one cylinder. During the intake process, the cold air absorbs the heat on the cylinder wall, piston, and cylinder head with high temperature during the suction and compression process, and the work consumed by the compressed air is equal to the adiabatic compression work plus the compression work increased by the heat absorbed by the air; combustion expansion works During the process, the heat of the high-temperature gas is transferred to the low-temperature cylinder wall, piston, and cylinder head, and the expansion work done by the gas is equal to...
