EGR DELETE VOLVO

VOLVO EGR DELETE

In Volvo engines, the EGR (Exhaust Gas Recirculation) system is designed to reduce emissions of nitrogen oxides (NOx) by recirculating a portion of the exhaust gas back into the engine’s intake. The exhaust gas is cooled and then routed back into the intake manifold where it is mixed with the incoming air. This serves to lower the combustion temperature in the engine, which helps to reduce the formation of NOx.

In Volvo engines, the EGR system is typically made up of several components, including the EGR valve, EGR cooler, and EGR pipe. The EGR valve is used to control the amount of exhaust gas that is recirculated into the intake. The EGR cooler is used to cool the exhaust gas before it is recirculated, and the EGR pipe is used to route the exhaust gas from the exhaust manifold to the intake manifold.

Like many other EGR systems, in the long term the EGR in volvo engines may suffer from a build up of carbon, which can lead to reduced performance and fuel economy, as well as engine misfires and increased emissions of other pollutants.

In order to fix this issues, a common solution is to perform an EGR delete, which is the removal or disabling of the EGR system. This can be done by either removing the EGR components or by reprogramming the engine control module to not use the EGR system. However, as i’ve mentioned earlier, this may not be legal in all jurisdictions, and can void the vehicle’s emission warranty, so it’s important to check the laws and regulations before doing any modification.
