Engine Principles 1

When the piston is at its highest point in the cylinder it is known as:

•             Top dead center (TDC) 

•     bottom dead center (BDC )

• After top dead center  ( ATDC )

• Before top dead center ( BTDC )

Crankshaft oil seals keep oil from leaking out the:

• front

• rear

• Both front and rear

• Basepan

Crankshaft turns at _____the Speed of the Camshaft

• 2x

• 3x

• 1/2x

• 1x

The Component that stops the piston from tipping in the cylinder is the

• Piston Ring

• Piston Skirt

• Connecting Rod

• Piston pin

What component ensures the synchronization of the crankshaft and camshaft?

• Timing Belt

• Oil Pump

• Water Pump

• Fuel Injector

What is the function of the camshaft in an engine?

• To control exhaust emission

• To control the intake and exhaust valves

• To increase fuel efficiency

• To monitor engine temperature

Which component is responsible for converting the linear motion of the pistons into rotational motion?

• Camshaft

• Crankshaft

• Connecting Rod

• Piston Ring

What is the main purpose of the valve spring in an engine?

• To seal the combustion chamber

• To return the valve to its closed position

• To inject fuel into the cylinder

• To monitor exhaust gases

The component that hold the Valves in the head

• Camshaft Lobes

• Valve Spring

• Valve Stem

• Keepers

What is the role of the piston pin in an engine?

• To connect the piston to the crankshaft

• To seal the combustion chamber

• To connect the piston to the connecting rod

• To lubricate the piston movement
