​ (a)   are the parts of the engine where the pistons circulate. They are made of very resistant materials, since they have to withstand the bursts of energy that move the engine.

• Cylinders
• Inlet valves
• Connecting rods
• Camshafts

The​ ​ (a)   is the glue that connects the parts of the engine. Its purpose is to turn the linear (up and down) motion of the pistons into rotational motion. One end is attached to the camshaft, via a timing belt.

• inlet valve
• crankshaft
• timing belt
• camshaft

The​​ ​ (a)   is a power management device for the engine. It is connected to the clutch, which is connected to the transmission.

• inlet valve
• camshaft
• flywheel
• exhaust valve

The​​ ​ (a)   is a reinforced rubber belt with teeth on one side. It connects the engine's crankshaft and camshaft, ensuring the valves open and close perfectly with the pistons.

• connecting rod
• timing belt
• inlet valve
• camshaft

The​​ ​ (a)   is a device that manages the timing of the engine. Its job is to regulate when fuel is let into the engine, and when exhaust is let out.

• camshaft
• inlet valve
• connecting rod
• exhaust valve

A crankshaft's job in an engine is to:

• deliver fuel to the cylinders

• change linear motion into rotational motion

• keep cylinder heads in place

What are the three common ways to arrange an engine's cylinder?

• V-6, V-8, HEMI

• inline, V, flat

• inline, flat, rotary

Which of the following connects the connecting rod to the piston?

• Rod Cap
• Connecting Rod
• Piston Pin
• Rod Bolt

When the cylinder head is bolted to the block, a ________________ is installed between the head and block to maintain an airtight and watertight seal.

• Manifold
• Head Gasket
• Crossover
• Header
