Abstract
An intake system is disclosed for conducting air to a v-configured, internal combustion engine. The engine includes an engine coolant crossover conduit which extends between cylinder heads and has coolant passages which operate to conduct coolant therebetween. A throttle body mounting flange extends outwardly from a side of the conduit and includes a throttle body mounting surface which surrounds an opening extending through the flange. A throttle body is mounted to the throttle body mounting surface of the throttle body mounting flange with the opening of the flange aligned with the throttle body bore for conducting inlet air from said throttle body and to a conduit extending between the flange and the intake manifold of the engine. An exhaust gas passage within the engine coolant crossover conduit extends from an exhaust gas source to an outlet in the throttle body mounting flange opening which, with an associated exhaust gas metering valve, regulates the flow of exhaust gas to the outlet where it is introduced into the intake air flow passing to the intake manifold. The throttle body mounting flange operates as a sink for heat from the coolant passages in the engine coolant cros…
