Internal combustion engine nitrogen-reducing and oxygen-increasing air inlet device and control method thereof

Abstract

The invention discloses an internal combustion engine nitrogen-reducing and oxygen-increasing air inlet device and a control method thereof. The internal combustion engine nitrogen-reducing and oxygen-increasing air inlet device comprises nitrogen filter pipes, a control system and an exhaust gas turbine connected with an exhaust pipe, wherein the wall pipe of the nitrogen filter pipes is provided with a first oxygen sensor, a low oxygen air exhaust valve and an air straight-through valve electromagnetic valve; one end of a turbine air pressing device is connected with an air filter; an air inlet manifold is connected with a plurality of air inlet manifolds of an engine; the air inlet manifold is provided with a second oxygen sensor. The air filter is used for filtering mechanical impurities in air, the turbine air pressing device is used for pressing each nitrogen filter pipe, oxygen in air is successfully filtered through the nitrogen filter pipes to enter an air cylinder under the combined action of the pressing of the turbine air pressing device and the air inlet suction of an engine, but the nitrogen is inhibited to pass through, so that the content of the oxygen in air entering the air cylinder through the nitrogen filter pipes is greatly increased, and then higher power can be achieved through oil burning, the burning is improved at the same, and the energy saving and environmental protection of the engine are really achieved.

Description

technical field [0001] The invention relates to an engine in the field of power engineering, in particular to an intake device for reducing nitrogen and increasing oxygen for an internal combustion engine and a control method thereof. Background technique [0002] On the one hand, the rapid development of the automobile industry has brought great convenience to human life and work, but on the other hand, it has caused a series of contradictions related to the living environment of human beings, the most important of which is that the exhaust pollution of the engine has seriously damaged the ecological environment of human beings. , high energy consumption has accelerated the depletion of petrochemical energy, and these contradictions will intensify over time. With the rapid increase of car ownership, the proportion of vehicle exhaust (engine emissions) in urban air pollution is increasing. When vehicles are driving on the road, due to the large amount of dust on the road sur...

AI Technical Summary

Problems solved by technology

As we all know: nitrogen in the air accounts for 78%, and oxygen only accounts for 21%. On the original air intake device, although people try every means to increase the amount of air entering the cylinder into the limited cylinder volume, as in "A Kind of Nitrogen The supercharging device proposed in the patent (ZL200720050064.8) of Oxygen Supercharging Device, in fact, the increase of oxygen is not much, but the increase of nitrogen is a lot. It can be seen that the technology of increasing the amount of air entering the cylinder has no effect of increasing oxygen. Not noticeable and contributes to NO in combustion engine emissions x increase
