The EGR (exhaust gas recirculation) system returns part of the exhaust gas to the intake manifold. This lowers combustion temperature and therefore the amount of nitrogen oxides (NOx) the engine produces. The EGR cooler cools the gas before it is recirculated so the effect is stronger.
VOLTREK supplies EGR valves and EGR coolers designed for precise flow control and for resistance to high temperature and soot deposits. The components are intended for direct fitment in place of the original part.
