Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] like figure 1 As shown, the present invention provides a kind of technical scheme:

[0027] The new two-stroke engine includes a piston 1 and a piston cylinder 2. The top of the piston cylinder 2 is equipped with a high-pressure intake valve 3 and an exhaust valve 4. The ECU controls the connection of the high-pressure intake valve 3 and the fuel injection nozzle 5. Its work The process is as follows:

[0028] One stroke: when the piston 1 moves towar...

Abstract

The invention discloses a novel two-stroke engine, and belongs to the technical field of engines. The novel two-stroke engine solves the problems that mixed burning of engine oil and fuel oil is carried out on an existing two-stroke engine, emission pollution is serious, and the working efficiency of a four-stroke engine is not high enough. The novel two-stroke engine comprises a piston and a piston cylinder block, a high-pressure air inlet valve and an exhaust valve are arranged at the top end of the piston cylinder block, the novel two-stroke engine is characterized in that an ECU is in control connection with the high pressure air inlet valve and an oil spraying nozzle, and the working processes include a first stroke completing air inlet, oil spraying and compression stroke and a second stroke which enables high-pressure air left in the piston cylinder block to be discharged out through the exhaust valve; and the first stroke and the second stroke work in a circulated and reciprocated manner, an engine crankshaft only needs to work by one circle for the first stroke and the second stroke. The novel two-stroke engine has the beneficial effects that the engine power is increasedby one time, the engine size is reduced, the oil-gas proportion is best, and energy saving is achieved; and the good economic benefit and the broad market prospect are achieved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a novel two-stroke engine. Background technique [0002] At present, there is a certain difference between the two-stroke engine and the four-stroke engine in the prior art. In the two-stroke engine, the exhaust port is arranged on the side wall of the piston cylinder, and when the piston moves to the bottom of the piston cylinder, the exhaust port is exposed. Exhaust, such a two-stroke engine must use oil-gas mixed combustion for lubrication, so the emission pollution is serious; the existing four-stroke engine overcomes the defect of insufficient exhaust volume, but it is in the process of exhaust , needs the piston to do work, and the exhaust gas in the piston cylinder is extruded from the piston cylinder. Therefore, it must be provided with four strokes, and the work efficiency still cannot be improved efficiently. Contents of the invention [0003] (1) Solved technical pr...
