Connected type mechanical supercharging two-stroke internal combustion engine of air intake system

Abstract

The invention relates to a connected type mechanical supercharging two-stroke internal combustion engine of an air intake system in the technical field of internal combustion engines. The connected type mechanical supercharging two-stroke internal combustion engine comprises air cylinders, pistons, a connecting rod, an air intake mechanism, an air intake valve, air release mechanisms, an air release valve, connecting pipes and a crankshaft, wherein one end of a first connecting pipe is connected with a third connecting pipe, and the other end of the first connecting pipe is communicated with the side wall face of a first air cylinder; and one end of a second connecting pipe is connected with the third connecting pipe, and the other end of the second connecting pipe is connected with a first air release mechanism. In the working process, a third piston and a fourth piston can utilize the mechanical energy of a first piston and a second piston through a crankshaft connecting rod mechanism. The timing of the air intake valve and the air release valve is controlled, so that a third air cylinder and a fourth air cylinder can supercharge the sucked air, therefore the first air cylinder and a second air cylinder can suck more air, and the effective power of the engine is increased. The connected type mechanical supercharging two-stroke internal combustion engine has a reasonable design and a simple structure and is suitable for mechanical supercharging devices of two-stroke engines.

Description

technical field [0001] The invention relates to a supercharging device in the technical field of internal combustion engines, in particular to a mechanically supercharged two-stroke internal combustion engine connected to an intake system 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 ...
