Embodiment Construction
[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0031] see figure 1 , which is a hydrogen pilot ignition type methanol engine combustion system provided by the present invention. The hydrogen pilot ignition type methanol engine combustion system uses methanol fuel as the base fuel and hydrogen as the igniter, and heats and gasifies the methanol fuel during the transportation process, and then mixes it with the hydrogen igniter and air in the gas. The mixture is mixed in the device 8 to form a mixed gas, and the hydrogen igniter in the mixed gas is ignited by the spark provided by the spark plug 3 in the cylinder 2 of the methanol engin...

The invention provides a hydrogen ignition ignition type methanol engine combustion system which comprises a methanol engine and a methanol storage device. The fuel supply system is used for providing gasified methanol fuel for the gas mixer; the ignition agent supply system is used for providing a hydrogen ignition agent for the gas mixer; the mixed gas is formed by mixing the gasified methanol fuel, the hydrogen ignition agent and air input by the gas inlet pipe in proportion; and then the mixed gas is input into the methanol engine cylinder through the gas inlet manifold and the gas inlet channel. A methanol fuel high-pressure injection system on a methanol engine is omitted. In the hydrogen ignition ignition type methanol engine combustion system provided by the invention, the ignition agent supply system can immediately provide the hydrogen ignition agent for the gas mixer when the methanol engine is started, and the spark plug provides electric sparks to ignite the hydrogen ignition agent in the mixed gas to form ignition flames; and the residual mixed gas is ignited by ignition flame, so that the problem that the cold start of the methanol engine is difficult can be effectively solved. The invention further provides a control method of the hydrogen ignition ignition type methanol 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 hydrogen pilot 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 and natural gas, and is considered to be the preferred clean fuel to replace petroleum fuels. Methanol has received widespread attention due to its extensive supply chain in China, 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 be widely used on a large scale, and it is ...
