Example Embodiment

[0043] The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0044] Please refer to Figure 1a-Figure 1c The internal combustion engine power plant includes a cylinder 100, a cylinder head 110 is provided on the cylinder, an intake port 111 is formed on the cylinder head, and an exhaust port 120 is provided under the cylinder.

[0045] The piston 200 cyclically reciprocates in the cylinder 100 driven by the crankshaft and the connecting rod. A movable part 300 is also provided in the cylinder. The movable part 300 can move between an initial position and an end position, and the initial position is higher than the top dead center, and the end position is higher than the bottom dead center. The movable member 300 has a first surface 310 and a second surface 320 opposite to each other.

Abstract

The invention discloses an internal combustion engine power device. The internal combustion engine power device comprises an air cylinder, a piston and a movable piece. The piston is arranged in the air cylinder and can reciprocate between an upper stopping point and a lower stopping point. The movable piece is arranged in the air cylinder and moves between the initial position and the tail end position. The initial position is higher than the upper stopping point, and the tail end position is higher than the lower stopping point. The movable piece is provided with a first surface and a second surface which are opposite. The movable piece is provided with gas channels capable of being closed or opened. By means of the additionally-arranged movable piece, the movable piece is provided with the gas channels capable of being closed or opened, waste gas and fresh gas are isolated in the air inlet and outlet process of the internal combustion engine power device, and the problems that due to the fact that fresh gas and waste gas are mixed in an existing two-stroke engine, the combustion efficiency is low and pollution is high are solved. The invention further discloses an engine and two running methods of the internal combustion engine power device.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an internal combustion engine power device, an engine and an operating method of the internal combustion engine power device. Background technique [0002] Existing internal combustion engines can be roughly divided into four-stroke engines and two-stroke engines according to the working process. A four-stroke engine includes four action processes of suction, compression, power and exhaust. This type of engine has stable operation and high gas combustion efficiency, and is widely used in various types of vehicles. However, there is no power output in the intake and exhaust strokes of this type of engine, but there is energy loss. [0003] The working process of the existing two-stroke engine includes two strokes: the first stroke: the piston moves upward from the bottom dead center, after the intake hole, exhaust hole and ventilation hole are closed simultan...
