Abstract

The invention discloses a spray turbulence device for air flow in an internal combustion engine cylinder. The device comprises a shell mechanism, an ignition mechanism, a crank-link mechanism and a spray turbulence mechanism. The ignition mechanism is arranged in the shell mechanism, and the crank-link mechanism is arranged on the lower side of the ignition mechanism. And the spray turbulence mechanism is arranged between the ignition mechanism and the crank-link mechanism. According to the spray turbulence device, lateral low-pressure and forward high-pressure airflow can be formed through an acceleration valve and a conical acceleration block, so that oil mist is accelerated, the oil injection effect is improved, the turbulent flow effect is improved through the spiral structure of a turbulent flow groove, the atomization impact effect can be improved through the situation that a lower opening is large, the diffusivity of the oil mist is guaranteed, and the combustibility is improved.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a spray turbulence device for airflow in a cylinder of an internal combustion engine. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller jet engines, but the internal combustion engines generally refer to piston internal combustion engines. Piston type internal combustion engine is the most common with reciprocating piston type. The piston-type internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expansion of th...
