Problems solved by technology
Due to fluid dynamics, when natural gas and air are mixed in the mixing device, there may be certain inhomogeneity. This inhomogeneity of mixing will lead to differences in the combustion state in each cylinder of the engine, thus affecting the engine performance. overall performance
[0003] The mixing uniformity of natural gas and air affects the combustion in the cylinder of the engine, and the combustion analyzer and other equipment cannot effectively mix the mixing ratio of the gas in the cylinder
It is impossible to evaluate the design of the mixing device and the mixing performance of the engine, so it is impossible to optimize the mixing device, which becomes one of the difficult problems in the combustion process of the engine cylinder

Description
technical field [0001] The invention relates to an analysis device for the mixing uniformity of engine intake air, and also relates to a specific analysis method of the analysis device. Background technique [0002] At present, domestic natural gas engines generally adopt pre-mixed single-point injection technology, that is, natural gas is injected into a mixing device through the gas rail, and mixed with air. The mixed gas then enters each cylinder of the engine, and then burns to release heat. Due to fluid dynamics, when natural gas and air are mixed in the mixing device, there may be certain inhomogeneity. This inhomogeneity of mixing will lead to differences in the combustion state in each cylinder of the engine, thus affecting the engine performance. overall performance. [0003] The mixing uniformity of natural gas and air affects the combustion in the cylinder of the engine, and the combustion analyzer and other equipment cannot effectively mix the mixing ratio of t...
