Visual experiment system for opposed-piston engine cylinder

Abstract

The invention discloses a visual experiment system for an opposed-piston engine cylinder. The visual experiment system comprises an optical engine, a motor, a power dynamometer, a visual cylinder body, an original piston, a visual lengthened piston, a reflector, a high-speed camera, a PC end, a cylinder pressure sensor, an angle marker, a fuel injector, a spark plug, an oil rail, an oil pump, an oil tank, an ECU and a charge amplifier. According to the visual experiment system, a quartz glass window is arranged on the visual cylinder body and the visual lengthened piston, so that the internalcondition of the cylinder body of the optical engine is conveniently observed; and meanwhile, the high-speed camera is used for shooting and then transmitting to the PC end for analysis processing, thereby data of various aspects of spray mixing and combustion process organization analysis in the engine cylinder are obtained, so that the effect of improving the performance of the engine is achieved, and the engine is more efficient in combustion and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the related field of internal combustion engine research, in particular to a visual experiment system in cylinder of an opposed piston engine. Background technique [0002] Cars have become an indispensable means of transportation in people's daily life. Cars are indispensable in people's lives, but there are also many environmental problems caused by cars. With the continuous deterioration of the environment, the concept of low-carbon environmental protection is becoming more and more popular, and the environmental pollution caused by automobile emissions is becoming more and more serious. my country's automobile pollution problem has become a major pollution source of the atmospheric environment, affecting human health. The emission regulations of countries around the world are becoming increasingly stringent, and the large number of engines has led to excessive consumption of non-renewable energy such as fossil energy. How ...

Problems solved by technology

However, these methods have certain defects. For example, the dynamometer diagram can only give an average of the entire combustion process, and cannot reflect the combustion characteristics of a certain moment or a certain area in the combustion chamber in detail; while using CFD software When simulating the working process of the engine, in order to make the simulation results accurate, one must ensure that the selected model is correct in advance, otherwise the error of the results will be large

It is generally difficult to accurately give the properties of various aspects of the engine on the current existing models, so most of the time it is impossible to better guide our actual work
