Opposed mechanical supercharging two-stroke internal combustion engine

Abstract

The invention provides an opposed mechanical supercharging two-stroke internal combustion engine, belonging to a technical field of the internal combustion engine. The engine comprises: cylinders, pistons, a connecting rod, an air inlet mechanism, an inlet valve, an air-releasing mechanism, an air release valve, a connecting pipe and crankshafts. The air inlet mechanism and the air-releasing mechanism are installed on the top of the second cylinder, the inlet valve is installed in the air inlet mechanism, the air release valve is installed in the air-releasing mechanism, one end of the connecting pipe is connected with the air-releasing mechanism, the other end of the connecting pipe is connected to a side wall surface of the first cylinder, and two ends of the connecting rod are respectively connected with the crankshaft and the piston. In the working process, the second piston can utilize mechanical energy of the first piston through a crankshaft connecting rod system; the second piston can carry out supercharging to inlet air of the second cylinder by control timing of the inlet valve and the air release valve, thus the first cylinder is enabled to intake more air, and effective power of the engine is improved. The internal combustion engine provided in the invention has advantages of reasonable design and simple structure, and the engine is suitable for mechanical supercharging system of the two-stroke engine.

Description

technical field [0001] The invention relates to a supercharging system in the technical field of internal combustion engines, in particular to an opposed supercharged two-stroke internal combustion engine of a two-stroke engine. Background technique [0002] With the development of modern society, people have higher and higher requirements on the power and economy of the engine. In the case of a certain displacement, the most effective way to increase the output power of the engine is to provide more fuel for combustion. It is easy to provide more fuel to the cylinder through the injector, but it is not so easy to provide the amount of air to match the increased amount of fuel at the same time; The effect is poor. When the fuel injection volume is constant and the cylinder air intake volume is large, the combustion is better, and the fuel consumption and emissions are lower. The traditional naturally aspirated engine completely relies on the vacuum formed in the cylinder ...
