Supercharger test bench combustion chamber air inflow proportion adjusting device and method

Abstract

The invention discloses a supercharger test bench combustion chamber air inflow proportion adjusting device. The device comprises a control device; a gas detector arranged at the outlet of the combustion chamber; a stepping motor, in control connection with the control device and controlled by the control device; a crank-link mechanism, the power input end of the crank-link mechanism being connected with the output shaft of the stepping motor; a driving gear, connected with the power output end of the crank-link mechanism; a gear transmission mechanism, the power input end of the gear transmission mechanism being in driving connection with the driving gear; a plurality of driven gears, in driving connection with the power output end of the gear transmission mechanism; and air guide wheelblades, coaxially connected with the driven gears and are driven by the driven gears to deflect. The invention further discloses a supercharger test bench combustion chamber air inflow proportion adjusting method. According to the invention, the ratio of primary air to mixed air in the combustion chamber can be adjusted, so that the effect of fully combusting fuel is achieved.

Description

technical field [0001] The invention relates to the technical field of ratio adjustment of the intake air volume of a combustion chamber, in particular to a device and method for adjusting the intake air volume ratio of a combustion chamber of a supercharger test bench. Background technique [0002] Exhaust gas turbochargers have been widely used in commercial vehicles, passenger vehicles, construction machinery and fans. Turbocharging technology not only saves energy and reduces emissions, but also is an important way to restore engine power in plateau areas. [0003] With the continuous maturity of turbocharging technology, the replacement speed of turbochargers is getting faster and faster. Designing a new turbocharger requires a lot of tests to verify its performance and reliability. Due to the experimental work The conditions are complex and changeable, and it is often necessary to make the supercharger operate under ultra-high temperature or low temperature conditions...

AI Technical Summary

Problems solved by technology

To make the supercharger operate under ultra-high temperature conditions, the only way to increase the fuel supply is to cause the air-fuel ratio of combustion to be too small, causing a large amount of incomplete combustion of fuel, which not only wastes fuel, but also increases the emission of pollutants such as CO Emissions, pollute the atmosphere, and affect the environment; and to make the supercharger operate at low temperature, the only way to reduce the fuel supply will cause the air-fuel ratio of combustion to be too large, resulting in excessive fuel air combustion and increasing NOX emissions

[0004] In view of the above problems, there is no special method to solve the domestic
