Resistance reducing and supercharging device of engine air intake channel

Abstract

The invention discloses a resistance reducing and supercharging device of an engine air intake channel. Smooth transition is adopted at a turning corner position, a guide plate is added in a corner channel, the guiding portions of air guiding sheets are punched, and accordingly eddy structures at vortexes A, B and C produced in a buffering air channel are damaged to make local flowing resistance loss effectively reduced. In addition, the length of a straight through air pipe is shortened to reach the front edge of a vortex D area, high-speed airflow in the straight through air pipe is utilizedto destroy an original vortex structure, accordingly the energy consumption problem of a vortex D in the prior art is solved, and thus local flowing resistance loss is effectively reduced. By adopting the air channel structure, airflow speed can be improved, air intake pressure is increased, and the supercharging purpose is achieved. When an engine is at low rotating speed, oil and gas in a combustion chamber are fully stirred and mixed due to increase of air-intake kinetic energy, and energy conservation and emission reduction effects are played.

Description

technical field [0001] The invention relates to the field of engine intake boosting, in particular to a drag reduction and boosting device for an engine intake passage. Background technique [0002] General automobiles, locomotives, ships or lawn mowers use internal combustion engines such as reciprocating engines as power sources. Qi and other four programs, and then generate power output. [0003] The energy crisis caused by the limited stock of fossil fuels and the air pollution caused by combustion emissions have continuously deteriorated the living environment of human beings. With the mass popularization of automobiles, the technical innovation of energy saving and emission reduction is the main way for the sustainable development of society. [0004] During the intake stroke of the engine, the air flowing into the intake passage of the engine will produce an inevitable flow loss, which can be divided into along-course resistance loss and local resistance loss. The i...

Problems solved by technology

[0005] like Figure 1 to Figure 3 As shown, it can be clearly seen from the velocity vector diagram that there are several typical structures (vortex A, B, C, D) that generate relatively large local resistance in the original airflow channel, and these local structures in the figure obviously appear large Vortex, the formation of these vortices makes the mechanical energy of the air flow irreversible dissipate at these positions, resulting in a large loss of intake kinetic energy, which can reduce the intake air velocity and intake pressure, and cannot achieve the purpose of boosting
