Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0019] Including: hydrogen nozzle 5, spark plug 6, gasoline nozzle 8 and other components are installed on the cylinder block of the rotary engine of the device, wherein the gasoline injection pressure is maintained at 14MPa ± 0.5MPa, and the gasoline nozzle 8 is placed at the right end of the long axis of the rotary engine, in the direction of the long axis. The included angle is 40°, and the included angle of the gasoline nozzle can ensure that the gasoline fuel spreads toward the spark plug area after injection, which is conducive to the formation of a stratified mixture near the spark plug; the hydrogen fuel injection pressure is maintained at 5MPa±0.5MPa, and the hydrogen nozzle is placed on the left side of the spark plug. The side is close to the short axis, and the included angle with the short axis is 50°. This placement method can ensu...

The invention designs a hydrogen-gasoline dual-fuel stratified combustion rotary engine and a control method thereof, in particular to a stratified combustion control method for regulating the hydrogen and gasoline injection strategies according to the rotary engine speed signal. The device mainly uses the output signal of the rotary engine speed sensor (7) as the control basis, judges the operating speed range of the rotary engine, and reasonably adjusts the injection strategy in combination with the hydrogen and gasoline direct injection nozzles in the cylinder, so as to improve the intake efficiency and realize the rotary engine. Dual-fuel stratified combustion can effectively improve the combustion process and reduce emissions, and realize the application of low fuel consumption and low emission rotary engines.
Description
technical field [0001] The invention designs a hydrogen-gasoline dual-fuel stratified combustion rotary engine and a control method thereof, in particular to a stratified combustion control method for regulating hydrogen and gasoline injection strategies according to a rotary engine speed signal, belonging to the field of internal combustion engines. Background technique [0002] With the increasingly stringent emission regulations, people's research on vehicles with various driving forms is increasingly in-depth, and the rotary engine, as a driving machine different from traditional internal combustion, has gradually entered people's field of vision. The rotary engine has the advantages of simple structure, small size, light weight, large power-to-weight ratio, and high power density, and is suitable as a power source to provide power for automobiles. This leads to problems of low combustion efficiency and high emissions. [0003] As a clean fuel, hydrogen does not contain...
