Compression combustion type methane engine combustion system and control method

Abstract

The invention provides a compression combustion type methane engine combustion system which comprises a methane engine, a methane storer, a fuel supply system which provides a gasified methane fuel toa mixer, an igniter supply system which provides a dimethyl ether igniter to the mixer and the mixer which mixes the gasified methane fuel, the dimethyl ether igniter and air in proportion into mixedgas and inputs the mixed gas into the methane engine through an intake manifold. After compression combustion of the dimethyl ether ignite by compression combustion, the compression combustion type methane engine combustion system provided by the invention then ignites the gasified methane fuel, so that a problem that it is hard to cold-start the methane engine can be solved effectively. A nozzleon a conventional air cylinder can be replaced to play a role of granulating the methane fuel, so that the combustion effect and the utilization ratio of the methane fuel in the air cylinder are guaranteed. The invention further provides a control method of the compression combustion type methane engine combustion system.

Description

technical field [0001] The invention relates to the technical field of methanol engines, in particular to a combustion system and a control method of a compression ignition type methanol engine. Background technique [0002] With the continuous improvement of people's living standards, environmental awareness is gradually increasing. With the increasing shortage of oil resources on the earth, various new energy vehicles are also produced and mature with the development of science and technology. Methanol is a substance synthesized from raw materials such as coal, natural gas, wood and garbage, and is considered to be the preferred clean fuel to replace petroleum fuels. Methanol has received widespread attention due to its extensive methanol supply chain in China, and its advantages of low price and low emissions from combustion in engines. However, the methanol engine is difficult to start at low temperature, which is one of the main reasons why the methanol engine cannot ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings of the existing compression ignition methanol engine combustion system that it is difficult to start at low temperature, that is, the cold start time is long and difficult, and the methanol fuel must enter the cylinder through the nozzle, and the methanol fuel is not fully combusted.
