Abstract

The gas engine infinitely variable intake resonance system belongs to the technical field of engines. The invention solves the problem that the effective volume of the existing gas engine intake resonant cavity cannot be adjusted with the engine speed, and better power cannot be obtained within the full speed range. The problem. The invention adopts the grid plate and the rotating shaft to divide the inner cavity of the resonant box into the left grid cavity, the right grid cavity and the middle grid cavity; the engine speed is obtained according to the gas engine model; the gas engine speed is divided into low speed range, medium speed range speed range and high speed range; respectively calculate the volume of the resonance box in different speed ranges, then calculate the left and right distances of the three grid cavities, and select the resonance box; when the engine is in different speed ranges, control the state of the grid plate so that the resonance box is in the different volumes. When the speed of the gas engine is in the low-speed range, the volume of the resonance box is the largest; when the speed of the gas engine is in the high-speed range, the volume of the resonance box is the smallest. The invention is used in gas engines.

Description

technical field [0001] The invention relates to a stepless variable air intake resonance system of a gas engine, which belongs to the technical field of engines. Background technique [0002] Gas fuel is an important part of the available energy and is known as the third largest energy source after coal and oil. As a gas fuel, natural gas is rich in resources and low in cost. When it is applied to engines in the form of compressed natural gas and liquefied natural gas, it has the advantages of small structural changes to the internal combustion engine and little changes in working indicators, and has become an important alternative. Fuels are widely used in the field of internal combustion engines. [0003] With the rapid development of economy and science and technology, gas engines have become more and more perfect. However, with the increasing shortage of energy and people's increasing attention to the problem of environmental pollution, people continue to put forward n...
