Engine with integral mounted EGR cooler

An internal combustion engine of the V-type having a dual bank of cylinder blocks joined at the bottom crankcase end and spaced laterally from each other at their top cylinder head ends to provide a V-shaped valley therebetween, the valley nestledly receiving therein in a mating manner a single engine intake manifold connecting the blocks, and an engine exhaust gas recirculation (EGR) gas cooler mounted integral to the underside of the manifold in the valley, the intake manifold including an EGR system including exhaust gas flow passages totally contained therein connecting engine exhaust gases to carburetor air/fuel flow inlet riser bores integral with the manifold and adapted to be connected to an EGR control valve mechanism operable to control flow through the passages, the cooler having an engine coolant inlet and an outlet each connected to the engine coolant flow passages, the cooler also having an EGR gas inlet and outlet connected to the exhaust gas flow passages for cooling of the EGR gases by the engine coolant.
