Description
Technical Field
The invention belongs to the technical field of automobile engines, and particularly relates to a full-visual optical engine.
Background
As the world is increasingly depleted in petroleum resources and the available petroleum resources are limited, and fuel economy is becoming more and more important in engine design and development. In addition, with the improvement of the living standard of people, the awareness of environmental protection is gradually enhanced, in order to meet the requirements of people on the green environment, the country continuously upgrades the emission regulations, and stricter requirements are put forward on the emission performance of the engine from the previous national third emission standard to the national fourth emission standard and then to the current national fifth emission standard. Under the driving of factors such as fuel economy and emission of the engine, the performance index of the engine is continuously updated.
The working process of the engine is a very complex process and mainly comprises a series of physical and chemical processes such as fuel injection, evaporation, mixing, ignition and the like under a turbulent state. This extremely complex process is accomplished in a very short time and with very limited working space, with high requirements for the controllability of the combustion. Optimizing the fuel injection and air intake control strategy, reasonably organizing the air flow motion in the cylinder, and using diversified fuels has greatly reduced the emission level of the traditional engine and continuously improved the combustion efficiency. Some new combustion modes are also being proposed, mainly Homogeneous Charge Compression Ignition (HCCI), premixed compression ignition (PCCI), etc. These combustion modes have higher combustion efficiency and economy and lower emissions.
For these combustion models, the conventional engine diagnosis means mainly measure and analyze the external characteristics of the engine, and then make a conjecture on the internal combustion state by combining with the calculator simulation, so that the combustion process of the engine cannot be analyzed on a visual microscopic level. In order to further understand and study the in-cylinder combustion process, information such as a temperature field, a speed field, a component composition and concentration thereof in the cylinder needs to be detected, and thus various optical means are needed to perform microscopic diagnosis on the internal combustion condition of the engine. At present, the optical means at home and abroad mainly comprise: mie, rayleigh, and spontaneous Raman scattering (Raman), coherent anti-Stokes Raman scattering, laser induced incandescent light techniques (LII), planar laser induced fluorescence techniques (PLIF), chemiluminescent methods, and optical tracers methods, among others.
For these optical diagnostic techniques, different types of optical engines have been designed, mainly with optical passages through the cylinder head, as in 1969 Scott realized optical passages on a two-stroke single cylinder diesel, so as to obtain visualizations of combustion and spray; the university of brinell in united kingdom has implemented visual engines of engine side and top surfaces on one IDI diesel engine. In addition, there are optical passages through the side wall, optical passages through the piston, etc. However, the existing optical engine still has the problems of difficult installation of the transparent quartz cylinder sleeve, inconvenient wiping of quartz glass and the like.
