The EGR valve (exhaust gas recirculation valve) is a mechatronic product installed on a diesel engine to control the amount of exhaust gas recirculation fed back to the intake system
The EGR valve is a mechatronic product installed on a diesel engine to control the amount of exhaust gas recirculation fed back to the intake system. It is usually located on the right side of the intake manifold, near the throttle body, and is connected to it by a short metal tube leading to the exhaust manifold. Its function is to control the amount of exhaust gas entering the intake manifold, so that a certain amount of exhaust gas flows into the intake manifold for recirculation. The EGR valve is a very important and critical component in the exhaust gas recirculation device.
EGR valve is divided into two types: mechanical type and electronic control type.
The EGR valve reduces the temperature of the combustion chamber by guiding the exhaust gas discharged from the combustion of the engine to the intake manifold to participate in the combustion, improving the working efficiency of the engine, improving the combustion environment, and reducing the burden on the engine, effectively reducing the emission of NO compounds, reducing knocking, and prolonging the time of each component. service life.
The full name is Exhaust Gas Recirculation, that is, exhaust gas recirculation [1] The system is used to reduce the discharge of nitrogen oxides (NOX) in the exhaust gas. Nitrogen and oxygen react chemically only under high temperature and high pressure conditions, and the temperature and pressure in the combustion chamber of the engine meet these conditions, especially during forced acceleration. When the engine is running under load, the EGR valve opens, allowing a small amount of exhaust gas to enter the intake manifold and into the combustion chamber along with the combustible mixture. The EGR valve is closed at idle, and little exhaust gas is recirculated to the engine. Automobile exhaust gas is a non-combustible gas (without fuel and oxidant) that does not participate in combustion in the combustion chamber. It reduces the combustion temperature and pressure by absorbing part of the heat generated by combustion to reduce the production of nitrogen oxides. The amount of exhaust gas entering the combustion chamber increases with engine speed and load
Exhaust gas recirculation is a method in which part of the exhaust gas is introduced into the inhaled fresh air (or mixture) during the working process of the engine, and returned to the cylinder for recirculation to participate in combustion. Its function is to reduce the emission of NOx. NOx is a very harmful gas to the human body, which is mainly generated under high temperature and oxygen-rich conditions. During the working process of the engine, if part of the exhaust gas is reintroduced into the cylinder in a timely and appropriate manner, because the main component of the exhaust gas has a relatively large specific heat capacity, CO2, the exhaust gas can absorb part of the heat generated by combustion and take it out of the cylinder, and has a good effect on the mixture. A certain dilution effect, thus reducing the maximum temperature and oxygen content of the engine combustion, thereby reducing the formation of NOx compounds.
However, excessive exhaust gas recirculation will affect the normal operation of the engine, especially when the engine is running at idle speed, low speed and low load and the engine is running in a cold state, and when the engine power is required at full load (full throttle), the recirculation Exhaust gas will have a serious impact on the performance of the engine. Therefore, the amount of exhaust gas participating in the recirculation should be automatically adjusted according to the actual working conditions of the engine and changes in working conditions. Practice has proved that, according to different engine structures, the amount of exhaust gas involved in recirculation generally varies between 6% and 13%.
In order to make the amount of exhaust gas recirculation not have an excessive impact on the engine performance, modern electronically controlled engines also adopt a closed-loop control strategy for exhaust gas recirculation, and an EGR valve position sensor is installed at the exhaust gas recirculation valve (some models also use exhaust gas temperature sensors). or pressure sensor), the closed-loop correction feedback control of the actual exhaust gas recirculation amount is carried out.Business travel space.
