Opposed mechanical supercharging four-stroke internal combustion engine

Abstract

The invention relates to an opposed mechanical supercharging four-stroke internal combustion engine in the technical field of the internal combustion engine. The opposed mechanical supercharging four-stroke internal combustion engine comprises air cylinders, pistons, connecting rods, air inlet mechanisms, air inlet valves, air bleeding mechanisms, air bleeding valves, a connecting pipe and a crankshaft; the air inlet mechanisms and the air bleeding mechanisms are arranged at the top ends of the air cylinders; the air inlet valves are arranged in the air inlet mechanisms; the air bleeding valves are arranged in the air bleeding mechanisms; the two ends of the connecting pipe are respectively connected with the first air inlet mechanism and the second air bleeding mechanism; and the two ends of the connecting rods are respectively connected with the crankshaft and the pistons. In the working process, the second piston can use the mechanical energy of the first piston through a crankshaft connecting rod mechanism; by controlling the timing of the air inlet valves and the air bleeding valves, the second piston can be used for supercharging air sucked by the second air cylinder, thereby enabling the first air cylinder to suck more air and improving the effective power of an engine. The opposed mechanical supercharging four-stroke internal combustion engine is reasonable in design and simple in structure and is suitable for a mechanical supercharging system of a four-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 four-stroke internal combustion engine of a four-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 cylinde...
