Method and device for increasing engine power and reducing tail gas emission

Abstract

The invention relates to a method and a device for increasing engine power and reducing tail gas emission. The method for increasing engine power and reducing tail gas emission includes utilizing a throttle valve slice which is composed of a plurality of air valve blades; making use of a center of a transverse section of a pipe controlled by a throttle to serve as a driving point at one end of each air valve blade; enabling each air valve blade to move around a shaft lever of the air valve blade and to be unfolded by inclining towards one direction, and forming vortex by air obliquely entering the pipe through the gaps reserved among the air valve blades inclined. The swirl flow is easy to be formed in an air inlet manifold to directly pressurize the air inlet manifold, so that stratified combustion and lean burn are easier to be formed, the fuel can be completely combusted, emissions of CO (carbon monoxide), HC (hydrocarbon) and NOx (nitrogen oxides) can be lowered, consumption of oil can be reduced, and the running cost of cars in slow running condition can be reduced.

Description

technical field [0001] The present invention relates to a method and device capable of improving engine power and reducing exhaust emission. Background technique [0002] As the driving situation of the car is constantly changing, the required engine power should also change accordingly. The change of the engine power during the driving process of the car is realized by changing the amount of combustible gas supplied. For this reason, the carburetor is equipped with a section The throttle valve is usually a circular or elliptical sheet valve that can rotate at a certain angle around its short axis. The throttle valve is connected to the accelerator plate in the cab by a series of rods. The driver steps on the accelerator pedal to the lowest position, the throttle valve is fully opened, and the channel cross-sectional area of ​​the mixture is the largest at this time. When the driver fully relaxes the accelerator pedal, the throttle valve minimizes the cross-sectional area o...

AI Technical Summary

Problems solved by technology

When the mixture concentration drops, when the mixture is burned again, its combustion value is reduced, so that the design power cannot be fully utilized

For a long time, the formation of carbon deposits and incomplete combustion make the power unable to reach the design value, thereby reducing the power and consuming more energy. Incomplete combustion also significantly increases the exhaust gas index, causing engine pollution and air pollution
