Abstract

The invention provides an energy-saving gas engine. A pressure stabilizer, a gas pressure control valve, an electronic control unit, a temperature sensor and an oxygen concentration detecting sensor are arranged, the concentration of input air and oxygen can be controlled in real time according to exhaust port temperature data and oxygen concentration data, and therefore closed-loop control can be achieved, and more intelligent control is achieved. Sufficient combustion of gas is guaranteed, pollution caused by insufficient combustion is prevented or insufficient output power caused by excessive combustion is prevented. A phase sensor is further arranged, it can be guaranteed that ignition is conducted when a piston of the engine reaches the maximum compression point, insufficient combustion is prevented, and fuel is saved. A load detection module is further arranged, the pressure of mixed gas is adjusted in real time according to the load situation, closed-loop control is achieved, the energy-saving gas engine is more intelligent, and output power is guaranteed.

Description

technical field [0001] The invention relates to a gas engine, in particular to an energy-saving gas engine. Background technique [0002] The types of gas mainly include CNG compressed natural gas, LNG liquefied natural gas, pipeline natural gas, biogas and LPG liquefied petroleum gas. The main component of natural gas is methane, and also contains a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc. Biogas is a combustible gas mainly composed of methane produced by anaerobic fermentation of organic waste under certain conditions of temperature, pH and airtightness. It usually contains 45-70% methane and is a good gas fuel that can completely replace gasoline or diesel for power generation. [0003] The current gas engine is not precise enough to control the input of air and gas, and it is difficult to adjust the mixing ratio of air and gas in real time according to the load, resulting in a low gas conversion rate and a relativ...
