Vortex exhaust structure of automobile engine

Abstract

The invention discloses a vortex exhaust structure of an automobile engine. The vortex exhaust structure comprises a flow regulation cylinder, wherein a gas introducing cylinder which is coaxial with the flow regulation cylinder is arranged at one end of the flow regulation cylinder; the vortex exhaust structure further comprises a cladding which is coaxially fixed outside the flow regulation cylinder; a plurality of guide plates are further mounted between the cladding and the flow regulation cylinder and twisted with the axis of the flow regulation cylinder serving as a central line in an Archimedes spiral manner, and every two adjacent guide plates form a spiral channel; and a plurality of gas distribution holes are formed in the side wall of the gas introducing cylinder. According to the vortex exhaust structure, an exhaust gas vortex is formed in the outlet of the spiral channel, so that the flowing of air flow is accelerated, dead angles in the bent position are changed into gas flowing areas, the problem of dead angles on an exhaust pipeline is solved, the exhausting is facilitated, pressure loss is avoided during low twisting of exhausting, high and middle twisting can be performed more smoothly, exhausting smoothness is improved to promote gas inlet smoothness, the burning rate of injected fuel is increased, and the fuel can be burnt and utilized for maximum efficiency.

Description

technical field [0001] The invention relates to an exhaust structure of an automobile engine, in particular to a vortex exhaust structure of an automobile engine. Background technique [0002] The engine is the heart of the car, which provides power for the car to run, and is related to the power, economy and environmental protection of the car. To put it simply, an engine is an energy conversion mechanism, that is, the thermal energy of gasoline, diesel or natural gas is transformed into mechanical energy by pushing the piston to do work through the expansion of the combustion gas in the sealed cylinder. This is the most basic principle of the engine. All the structures of the engine are for energy conversion. The engine has been with the car for more than 100 years. It has been greatly improved in terms of design, manufacture, technology, performance and control, but its basic principle remains the same. No change. This is an era full of creativity. The designers of thos...

AI Technical Summary

Problems solved by technology

At present, the engine of a car is exhausted in this way during use: the air entering the engine is fully mixed with gasoline and then compressed or ignited, and the gas volume expands rapidly during rapid combustion, and the pressure increases. When the exhaust valve is opened, the high-pressure and high-temperature post-combustion exhaust gas is pressed into the exhaust pipe and discharged from the chimney. During the exhaust process, the structure such as the bend of the exhaust pipe is likely to cause a dead angle of the air flow, making it difficult for the exhaust gas to be discharged.
