On a turbocharged diesel engine this can be achieved either by using the geometry of the turbine vanes (VGT) or by fitting a throttle on the intake manifold. WebThe exhaust gas passes through this small radiator and lowers the exhaust gas to a temperature that it is able to be introduced into the intake system at. On the 6.0 Powerstroke engine, it is an extremely simple system consisting only of a cooler and a valve. When the engine’s computer decides the egr valve should open under certain ... cyclops tricycle
