Disclosed is an intake gas adjusting system of a gas engine. The intake gas adjusting system of the gas engine comprises an air inlet pipe, a gas engine speed governor and a PLC. The air inlet pipe is divided by a metal plate into a first cavity and a second cavity in the radial direction, a first air valve and a second air valve are arranged in the first cavity and the second cavity respectively, the first air valve is connected with the gas engine speed governor, and the second air valve is connected with the PLC. The PLC is connected with a rotating speed measuring instrument and a temperature sensor, the rotating speed measuring instrument is arranged on the side of a flywheel of the gas engine, and the temperature sensor is arranged on the inner wall of an exhaust pipe of the gas engine. By the adoption of the intake gas adjusting system of the gas engine, accurate adjustment of the air-fuel ratio of the gas engine can be achieved, the working efficiency of the gas engine is improved, then the output power of gas per unit is increased, and safety is higher.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an air intake adjustment system of a gas engine. Background technique [0002] The engine is a mature mechanical device for generating power. People use more internal combustion engines including gasoline engines and diesel engines. However, in today's increasingly serious environmental pollution, people begin to use more other types of engines, such as gas engines. Gas engines can use natural gas, liquefied petroleum gas, etc., and carbon emissions are greatly reduced. [0003] The gas burned by a gas engine is a mixture of air and gas. The mixing ratio (referred to as the air-fuel ratio) has a relatively large impact on the performance of the gas engine, and the amount of mixed gas is different at different speeds and different output powers. The air intake volume needs to be adjustable, and it needs to be adjusted synchronously with the gas volume. [0004] The biomass power...
