Problems solved by technology

[0002] Most of the coal mine gas has been evacuated recently, and it has not been successfully used in reciprocating piston engines. The main reason is that the performance of the mixer cannot adapt to the wide range of changes in the methane content of the gas, and the air-fuel ratio cannot be guaranteed.

Abstract

The electrically controlled fuel gas mixer features that the cylinder temperature signal, the engine load signal and the limiting switch signal are fed to CPU, and the signal from CPU is fed to parameter display and step motor driver circuit to control the on-off and rotation in different direction. The mixer installed coaxially with the step motor consists of the upper cylinder, the middle Venturi tube, the T-junctor with fuel gas inlet, air inlet and mixed gas outlet, step motor installed vertically with universal coupling on its shaft, air regulating valve and the lower slide valve. The present invention controls the air-to-fuel gas ratio electromechanically.

Description

technical field [0001] The invention relates to an electronically controlled gas mixer for a gas engine. Background technique [0002] Most of the coal mine gas has been evacuated recently, but it has not been successfully used in reciprocating piston engines. The main reason is that the performance of the mixer cannot adapt to the wide range of changes in the methane content of the gas, and the air-fuel ratio cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide an electronically controlled gas mixer capable of ensuring that the engine works at a reasonable air-fuel ratio. [0004] Technical scheme of the present invention is realized in the following manner: [0005] Electronically controlled gas mixers include: [0006] Central processing unit, cylinder temperature measurement circuit, engine load measurement circuit, parameter display circuit, stepper motor drive circuit, stepper motor and mixer. Cylinder temperat...
