Opposed-piston engine

Abstract

Belonging to the field of internal-combustion engine, the invention in particular relates to an opposed-piston engine, comprising a cylinder, a working piston, a crank shaft and the like; wherein the cylinder is provided with an air piston which is opposite to the working piston and moves in opposite direction; the cylinder block face at one side of the air piston is provided with an intake valve and an outtake valve; the intake valve is communicated with the atmosphere, the air piston is provided with a mechanism which can enable the air piston to reset; the air outtake is connected with an air storage mechanism for storing high pressure gas by an oil-gas separating device; the middle part of the cylinder is provided with a combustion chamber which is provided with an air inlet, an air outlet, a fueling injection device and an ignition unit; the air inlet is connected with the gas storage mechanism by a first electromagnetic valve. With the opposed-piston engine adopted, oil fuel consumption and vibration can be reduced by big margins and motorcycles or single-cylinder automobiles with even smaller vibration than the vibration of 4-cylinder automobiles can be produced; in addition, the engine of the invention can serve as auxiliary power of hybrid vehicles.

Description

【Technical field】

[0001] The invention belongs to the field of internal combustion engines, in particular to an opposed piston engine. 【Background technique】

[0002] The operation process of a traditional internal combustion engine consists of four parts: 1. The intake stroke, the piston is driven by the crankshaft to move from the top dead center to the top dead center, and at the same time, the intake valve opens and the exhaust valve closes. When the piston moves from the top dead center to the bottom dead center, the volume above the piston increases, and the gas pressure in the cylinder drops, forming a certain degree of vacuum. Due to the opening of the intake valve, the cylinder communicates with the intake pipe, and the mixture is sucked into the cylinder. When the piston moves to the bottom dead center, the cylinder is filled with fresh mixed gas and exhaust gas not discharged in the previous working cycle. 2. In the compression stroke, the piston moves from the ...
