Exhaust Gas Recirculating Valve

A small amount of exhaust gas is taken from left rear exhaust flange and cooled in a cooling coil. Any coarse impurities are filtered out by cyclone filter. Exhaust gas which has been cleaned by filter passes into intake manifold by way of vacuum controlled exhaust recirculating valve. A relay gives signals to valve when proper conditions exist for exhaust gas recirculation. Exhaust gas recirculating valve controls exhaust gas flow, depending on throttle valve position, so that mixing is only possible during partial load operation.
