Abstract

The invention relates to an infinitely variable intake resonator system of a gas engine and belongs to the technical field of engines. The infinitely variable intake resonator system aims to solve theproblems that the effective volume of an intake resonant cavity of an existing gas engine cannot be adjusted along with the rotating speed of the engine and relatively good power cannot be obtained in a full rotating speed range. According to the infinitely variable intake resonator system, An inner cavity of the resonant cavity is divided into a left side divided cavity, a right side divided cavity and a middle divided cavity by using dividing plates and a rotating shaft; the rotating speed of the engine is obtained according to model of the gas engine; the rotating speed of the gas engine is divided into a low speed interval, a medium speed interval and a high speed interval; the volumes of resonance boxes in different rotating speed intervals are calculated separately, and the left-right distances of the three divided cavities are calculated, so that the resonance boxes are selected; when the engine is in different rotating speed intervals, the states of the dividing plates are controlled, so that the resonance boxes have different volumes; when the rotating speed of the gas engine is in the low speed interval, the volume of the resonance box is the largest; and when the rotating speed of the gas engine is in the high speed interval, the volume of the resonance box is the smallest. The infinitely variable intake resonator system is used for the gas engine.

Description

technical field [0001] The invention relates to an infinitely variable 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 available energy, known as the third largest energy after coal and oil. As a gaseous fuel, natural gas is rich in resources and low in cost, and when it is applied to engines in the form of compressed natural gas and liquefied natural gas, it has the advantages of small changes to the internal combustion engine structure and little change in working indicators, and has become an important alternative The fuel is widely used in the field of internal combustion engines. [0003] With the rapid development of economy and science and technology, gas engines are becoming more and more perfect. However, with the increasing shortage of energy and people's increasing concern about environmental pollution, people continue to put forward new requirements for the ...
