High-ignition-point fuel compression ignition and combustion regulation and control device based on flame jet flow control

Abstract

The invention discloses a high-ignition-point fuel compression ignition and combustion regulation and control device based on flame jet flow control. The high-ignition-point fuel compression ignition and combustion regulation and control device comprises a spark plug (1), a pre-combustion chamber ejector (2), a main combustion chamber ejector (3) and a pre-combustion chamber body (4). The pre-combustion chamber main body (4) is arranged on the main combustion chamber (6), a pre-combustion chamber cavity (5) is formed in the pre-combustion chamber main body (4), the pre-combustion chamber ejector (2) and the pre-combustion chamber spark plug (1) are installed at two different positions on one side of the pre-combustion chamber main body (4) respectively, and the head of the pre-combustion chamber ejector (2) and the head of the pre-combustion chamber spark plug (1) extend into the pre-combustion chamber cavity (5). The pre-combustion chamber cavity (5) is communicated with the main combustion chamber (6) through a spray hole; the main combustion chamber ejector (3) is fixed to the other side of the pre-combustion chamber body (4), and the head of the main combustion chamber ejector (3) extends into the main combustion chamber (6). The use performance of the low-carbon zero-carbon fuel can be effectively widened, and wide popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a high ignition point fuel compression ignition and combustion control device based on flame jet control. Background technique [0002] As the greenhouse effect continues to intensify, and driven by the domestic goals of "carbon neutrality" and "carbon peaking", engines use low-carbon / zero-carbon fuels (natural gas, hydrogen, ammonia, etc.) to replace traditional fossil fuels to reduce Carbon emission has become a trend of industry development and a research hotspot. However, for low-carbon fuels / zero-carbon fuels, the chemical reaction activation energy is high, the low-temperature activity is weak, and the thermodynamic conditions for self-ignition are relatively harsh; especially for ammonia fuels, there are also high ignition energy and slow free radical propagation speed. , Narrow flammable limit and other issues. Therefore, at present, the ...
