Problems solved by technology

However, because the exhaust gas of the two-stroke engine is not fully discharged, and the scavenging port is closed before the exhaust port, additional exhaust gas is generated, and the air pressure is difficult to increase; in fact, the performance of the two-stroke engine is not ideal, and the oil is discharged without burning out, causing waste and pollution

Embodiment Construction

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] Such as figure 1 As shown, in a two-stroke engine modified from a four-stroke engine, high-pressure compressed gas is provided outside cylinder 1, which combines the intake stroke and the power stroke into one stroke, plus an exhaust stroke, so that the two strokes are completed A working cycle of the engine.

[0019] Compared with the four-stroke engine, the two-stroke engine has two strokes less, the...

Abstract

The invention relates to a two-stroke engine transformed from a four-stroke engine. Compared with a traditional multi-stroke engine, the method that the inlet gas is compressed externally is adopted, so that the compression stroke of the engine is omitted, and accordingly the four-stroke engine has the possibility of the two-stroke mode. Compared with the four-stroke engine, two strokes are omitted, so that the power performance is better, the structure is simple, the size is small, and the weight is low; compared with the traditional engine, the compression stroke is omitted, advanced ignition is not needed, and therefore the knocking phenomenon is eliminated; and the independent combustion chamber space is omitted, exhaust is thorough, and the combustion efficiency is substantially improved.

Description

Technical field [0001] The invention belongs to the technical field of piston internal combustion engines, and particularly relates to a two-stroke engine modified from a four-stroke engine and a working method thereof. Background technique [0002] According to the number of strokes required to complete a working cycle, engines can be divided into four-stroke engines and two-stroke engines. In a four-stroke engine, for every two revolutions of the crankshaft (720 degrees), the piston reciprocates twice, and the engine completes a work cycle, that is, each stroke completes a work cycle. In a two-stroke engine, every time the crankshaft rotates one revolution (360 degrees), the piston reciprocates once, and the engine completes a working cycle, that is, every two strokes complete a working cycle. [0003] The existing four-stroke engine has an intake stroke and a compression stroke. Its existence fundamentally reduces the working efficiency of the engine, increases the load, and it...
