Exhaust Gas Recirculation (EGR) The EGR system directs exhaust gases into the inlet manifold to be used in the combustion process. The principal effect of this is to reduce combustion temperatures, which in turn reduces Nitrous Oxide (NOx) emissions. The aluminium EGR valve is fitted at the inlet to the intake manifold. It is supplied by cooled air via the intercooler. + ENGINE MANAGEMENT SYSTEM – Td6, DESCRIPTION AND OPERATION, Description.
