Problems solved by technology

The disadvantage of this kind of working cycle is that there are many strokes, and more strokes will take up more time share. Therefore, the time for doing work is only 1 / 4; the work efficiency is low; more strokes lead to more friction losses of the mechanism. The inertia of the power mechanism consumes a lot of power; for this reason, we have analyzed that the third stroke and the fourth stroke can be completely omitted, only the first and second strokes need to be reserved
In addition, since the crankshaft rotation feedback is used as the motion control of the four strokes, the motion modes of the four strokes are exactly the same, which cannot be optimized separately according to the needs, which is another disadvantage

Abstract

The two-stroke working method of two-stroke engine includes the following steps: a. the first stroke is expansion stroke, including air admission, closing admission valve, ignition, combustion, piston movement to move screw rod to drive scroll cover and make it rotate, clutch combination, clutch drives the output mechanism and makes it rotate and outputting powder; and second stroke is exhaust stroke, including: releasing clutch and back-pushing piston to the original position by reset spring. Said invented two-stroke engine includes engine body, air admission and exhaust valves controlled by electromagnetic valve, conversion component for converting linear movement into rotary movemkent, reset spring and clutch, etc.

Description

technical field [0001] The invention belongs to the field of internal combustion engines and engines. Background technique [0002] Existing engines used in automobiles, trains, ships, etc. all use crank-link mechanism to complete the conversion from linear motion to rotary motion. This mechanism is not only a component for converting power, but also a work cycle control component. The movement is fixed as the first stroke-work, the second stroke-exhaust, the third stroke-suction, and the fourth stroke-compression air, which has become a classic of piston movement. The disadvantage of this kind of working cycle is that there are many strokes, and more strokes will take up more time share. Therefore, the time for doing work is only 1 / 4; the work efficiency is low; more strokes lead to more friction losses of the mechanism. The power consumed by the inertia of the power mechanism is large; for this reason, we have analyzed that the third stroke and the fourth stroke can be om...
