Exhaust gas recirculation valve seems to be witnessing major traction in light commercial and heavy commercial vehicles

 

The exhaust gas recirculation (EGR) valve is a device used to control the quantity of poisonous gas produced during the combustion of fuel. It helps in reducing the pollutants that are released into the atmosphere after combustion. A closed EGR vented system gives excellent emissions and is usually installed at the point where the muffler joins the exhaust system. The reason for selecting this type of system is to maximize the performance and efficiency of the exhaust system.

The main purpose of an exhaust gas recirculation valve is to act as a bleed-off or outlet for unwanted gases produced by the exhaust system. If there is an open exhaust system, then these valves help in bleeding off excess exhaust gasses from the vehicle. Furthermore, it helps in maximizing the power of the engine and at the same time reduces the amount of noise created by the exhaust system. Generally, an exhaust gas recirculation valve is placed close to the catalytic converter, which is also known as a catalyst. The purpose of the valve is to close when the car is on its way to the destination and open again when the car comes back. This helps in protecting the catalytic converter and is thus essential for ensuring the proper performance of the exhaust system.

In case of any malfunction in the EGR, then the valve automatically closes. However, there are certain parameters that need to be met for the auto-closing of the valve. Generally, all cars come with the standard EGR valve, which does not require any type of openers or shutters. However, there are many parts of the vehicle that can cause the failure of the exhaust gas recirculation valve such as a faulty oxygen sensor, exhaust pipe, and many others. If the part that fails has a metallic component, then it is very important to replace the part in time because the failure of this part may cause a fatal gas leak. Recently, in September 2020, WVE Vehicle Electronics introduced 472 new part numbers for variety of sensors, switches, and fuel injection products.
