What is an EGR Cooler
For the good part of the last half-century, automotive engineers have worked hard to reduce emissions and make cars more environmentally friendly. They found several solutions, in that regard, like using unleaded fuel, introducing catalytic converters, opting for electronic fuel injection and adding an Exhaust Gas Recirculation (EGR) system to the mix. The EGR system is the least understood by the masses out of all these solutions. We are about to change that with this article. Here we will talk about the EGR system and one of its important components, the EGR cooler . So, without further ado, let’s dig in! The EGR System Before we start talking about the EGR Cooler, it is important to first explain the workings of the EGR system. The Exhaust Gas Recirculation system sucks in the byproduct of combustion and sends it back into the air intake system, practically reducing the amount of oxygen going into the cylinders. Less oxygen leads to incomplete combustion, lower combustio...
