Optical engine

Abstract

The invention relates to an optical engine, wherein a transparent cylinder sleeve is arranged between a cylinder body and a cylinder cover of the engine, a piston is the original piston of the engine, and the length of the transparent cylinder sleeve is greater than the stroke of the engine. The invention specifically provides the optical engine which is based on rapid transformation of a multi-cylinder prototype machine and is applicable to researching the formation of a flow field, spray and mixed gas in the cylinder of the engine, in particular to researching the formation of the mixed gasof the optimized engine and a direct-injection engine in the cylinder.

Description

technical field [0001] The invention relates to the field of engines, in particular to an optical engine. Background technique [0002] At present, there are few optical engines in China, which are mainly used to study the combustion situation in the cylinder. According to the position of the transparent window, there are mainly two types. One type uses a transparent piston. Due to the fixed problem of the transparent piston, the transparent piston can only be as large as possible. Therefore, in this way, the optical engine can only see part of the flow field in the combustion chamber or combustion. The other type is based on the use of transparent pistons, adding a very short transparent quartz cylinder liner, because the transparent quartz glass cylinder liner is very easy to be scratched by the general piston ring, and it is very difficult for the piston ring to move between two different media. Ensuring smooth movement is also easy to damage the piston ring or the opti...
