Abstract
A motor vehicle having a transversely positioned engine in a forwardly disposed engine compartment. The exhaust manifold is formed rearwardly of the engine and supplies exhaust gases to a catalyzer so that the engine will shield the exhaust manifold and catalyzer from cooling air flow. An intake manifold extends forwardly from the engine and engine accessories are disposed beneath the intake manifold and forwardly of the cylinders of the engine so as to shield the occupants of the vehicle from the noise of the accessories. In addition, a crushable plenum chamber extends across the front of the intake manifold and forwardly of the accessories for silencing and also to absorb impacts. The crushability of the plenum chamber causes it to slow the engine on impact for further safety protection.
