The EGR valve for less pollution?

EGR Meaning : Exhaust Gas Recirculation
The EGR valve is an important component in internal combustion engines. It is used to reduce exhaust emissionsThis is particularly true of nitrogen oxides (NOx), which are harmful to the environment and human health. In this article, we'll explain how the EGR valve works and how it helps to reduce emissions.
The EGR valve is a valve located between the intake manifold and the exhaust manifold. Its role is to reduce temperature of combustion by reinjecting part of the exhaust gases into the intake manifold. This reduces the amount of oxygen available for combustion, thereby lowering the engine's fuel consumption. production of nitrogen oxides.
The EGR valve is controlled by the engine ECU, which opens and closes the valve according to various parameters such as engine load, engine temperature, engine speed and gas pedal position. When the EGR valve opens, part of the exhaust gas is re-injected into the intake manifold, reducing the amount of oxygen available for combustion.
However, reducing the amount of oxygen can also have an impact on engine performance, particularly at low revs. For this reason, some vehicle owners remove the EGR valve to improve engine performance.
Is it illegal to remove an EGR valve?
It should be noted that the removal of the EGR valve is illegal in many countries due to its effect on exhaust emissions. However, a clogged EGR valve has negative effects on engine life, as well as fuel consumption.
In conclusion, the EGR valve is a key component in internal combustion engines, helping to reduce exhaust emissions, particularly nitrogen oxides. Although it has negative effects on engine performance, it is important to keep it in good working order to reduce the environmental impact of motor vehicles.
