For example, there is neither an intake or exhaust manifold on the motor.

Lotus says the integrated exhaust manifold reduces weight, improves durability and eliminates 18 parts.

That means the engine block, cylinder head and exhaust manifold are a single casting.

He then bolted the exhaust manifold over the intake so the muffler connection barely touched the hub cap.

The exhaust manifold is cast into the cylinder head, a one-piece design that reduces the temperature of exhaust gases.

GM said some of the vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold under hard braking.

Solomon told the civilians of matching vacuum in intake manifolds to pressure from exhaust manifolds.

The principal carbon-steel pressed parts used on the Liberty engine were the water jackets and the exhaust manifolds.
