Exam 32: Intake and Exhaust Systems

What materials are exhaust pipes typically made from?

Many mufflers are produced with drain holes to allow condensation to drip out.

A restricted exhaust system can cause ______.

Engine vacuum may be used to operate the ______.

Boost pressure is measured with a pressure gauge ______.

What are the two ways of artificially increasing the amount of airflow into the engine?

Exhaust manifold gaskets are being discussed. Technician A says many modern vehicles are built without gaskets between the cylinder head and exhaust manifold. Technician B says when performing any service on theses engines that will require removing the manifold from the head, a new gasket should be installed.

What are the primary component parts of a turbocharger?

Atmospheric pressure appears as ____________________ on most pressure gauges.

How is vacuum created inside the engine?

Technician A says proper tuning of the exhaust manifold tubes can create a partial vacuum that helps draw exhaust gases out of the cylinder, improving volumetric efficiency. Technician B says combined headers allow the cylinders next to each other in the firing order to be combined. This increases exhaust efficiency. Who is correct?

What is the function of the exhaust flex joint?
