EGR Coolers, found within the Engine Miscellaneous section of Engine Parts, are critical components in modern passenger car and commercial vehicle emissions control systems. These coolers are positioned within the Exhaust Gas Recirculation (EGR) circuit, responsible for reducing NOx (nitrogen oxides) emissions. EGR Coolers function by lowering the temperature of recirculated exhaust gas before it re-enters the engine's intake manifold, enhancing combustion efficiency and further minimizing pollutant formation. Typically constructed from robust materials like cast iron or stainless steel to withstand high temperatures and pressures, these coolers are essential for maintaining regulatory compliance and optimal engine performance. Examples in this category include coolers for Volvo Construction equipment (MPN VOE21905787), Volvo Trucks, and various MAN applications like MPN 81473016067 or 51055040122, as well as coolers for Auger.
