Independent controllable intake-exhaust two-stroke (capable of being changed into four-stroke) internal-combustion engine system

Abstract

The invention discloses an independent controllable intake-exhaust two-stroke (capable of being changed into four-stroke) internal-combustion engine system which is used for solving the defects including low fuel efficiency, large emission pollution, participation of engine oil in combustion and the like of a two-stroke internal-combustion engine by applying the independent controllable intake-exhaust system, so that the energy is saved, the emission is reduced, the pressurized working conditions of the two-stroke internal-combustion engine are realized, the defect that the power per liter of a four-stroke internal-combustion engine is lower than that of the two-stroke engine is solved, and a completely new function of freely converting between the two strokes and the four strokes in one internal-combustion engine is creatively realized. Moreover, the independent controllable intake-exhaust two-stroke internal-combustion engine system is simpler in structure, lighter, provided with theoretical maximum power which is twice that of the conventional four-stroke pressurizing internal-combustion engine, integrated with the advantages of the two-stroke internal-combustion engine and the four-stroke internal-combustion engine and capable of making up the defects of the two-stroke internal-combustion engine and the four-stroke internal-combustion engine, and therefore, the independent controllable inlet-exhaust two-stroke internal-combustion engine system is an internal-combustion engine system with a completely new principle and a completely new manufacturing method, and a novel power choice is provided for the vehicle industry and other equipment manufacturing industries.

Description

Technical field [0001] The invention relates to the operating principle and manufacturing method of a novel independent controllable intake and exhaust two-stroke internal combustion engine, in particular to a 2 / 4 variable-stroke internal combustion engine system. Background technique [0002] Due to the structural principle of the traditional two-stroke internal combustion engine, there are defects such as low fuel efficiency, large emission pollution, and engine oil participating in combustion. The invention patent "00136557.6 Two-stroke structure / four-stroke internal combustion engine system" (the inventor is Luo Xianan, one of the applicants for this patent) The above problems have been solved, but the system cannot use the supercharging function, thereby limiting the further improvement of its power per liter; the present invention discloses a two-stroke supercharged internal combustion engine, and innovatively invented an independent controllable intake device And an i...

Problems solved by technology

[0005] Principle and manufacturing method 1 is: "independent controllable intake and exhaust two-stroke internal combustion engine"; the intake air of the traditional two-stroke internal combustion engine is separated, an independent controllable intake device is set, and combined with the mature direct fuel injection in the cylinder technology, it can solve the traditional two-stroke internal combustion engine oil participating in the combustion, and the use of mixed gas containing fuel for ventilation, so that it can achieve the same environmental protection working mode as the four-stroke internal combustion engine, and double the working efficiency of the four-stroke internal combustion engine (720° is reduced to 360° for one working cycle), and then by setting a controllable exhaust device, the exhaust port is controlled to close in advance, and the time difference between it and the lagging closing time of the intake port is used to pressurize the gas in the cylinder to solve the problem. It overcomes the defect that the air intake port and the exhaust port of the traditional two-stroke internal combustion engine are directly connected to each other and cannot be supercharged, and realizes a new working principle of an environmentally friendly two-stroke supercharged internal combustion engine. cost, increased reliability and service life of internal combustion engines
