AI Technical Summary

Problems solved by technology

When the gas engine currently used is working, the gas and the combustion air are mixed according to a fixed ratio, which cannot be adjusted and changed according to the working conditions of the engine. The engine power can only be controlled by controlling the intake air according to the working conditions of the engine. The output of the engine increases the energy consumption of the engine and reduces the power performance of the engine

Embodiment

[0015] Embodiment: As shown in the accompanying drawings, the fuel gas supply device for a gas engine includes a mixer 4, the intake end and the gas outlet end of the mixer 4 are respectively provided with throttle valves, and the intake air volume is controlled by the throttle valve at the gas outlet end of the mixer 4 , through the throttle valve at the intake end of the mixer 4, the size of the gas entering the mixer 4 can be controlled, so that the mixing ratio of the gas and the combustion air can be adjusted, so that the engine can be provided with different mixing ratios of gas according to different working conditions of the engine, the mixer The gas outlet of 4 links to each other with combustion chamber 2.

[0016] The quantity of the mixer 4 is two, and after the two mixers 4 are connected in parallel, they are connected in series with the throttle valve at the intake end of the mixer 4, and the quantity of the mixer 4 can be increased or decreased as required.

Abstract

The invention relates to a gas supply device for a gas engine, which comprises a mixer. A throttle is respectively arranged at a gas inlet end and a gas outlet end of the mixer, the throttle at the gas outlet end of the mixer is used for controlling the gas inlet capacity, and the throttle at the gas inlet end of the mixer is used for controlling the capacity of gas entering the mixer, so that the mixing proportion of the gas and combustion air can be controlled. According to different working conditions of the gas engine, the gas with different mixing proportion is provided for the gas engine, energy consumption of the gas engine is reduced greatly, and power performance of the gas engine is improved.

Description

technical field [0001] The invention relates to a gas supply device, in particular to a gas engine gas supply device. Background technique [0002] At present, gas engine, as an economical and environmentally friendly power equipment, has been recognized by people and has been widely used in various industries such as power and power generation. When the gas engine is working normally, the gas and combustion-supporting air need to be mixed first and then sprayed into the cylinder of the gas engine to ignite and burn for work. People usually solve this problem by setting a mixer on the intake pipe of the gas engine. The mixer The air outlet end is provided with a control valve to control the intake air volume. When the gas engine currently used is working, the gas and the combustion air are mixed according to a fixed ratio, which cannot be adjusted and changed according to the working conditions of the engine. The engine power can only be controlled by controlling the intake...
