4. Identify the part or item associated with the internal-combustion engine that the statement is
describing. Choose from the following parts: cylinder, engine block, piston, cylinder head,
combustion chamber, intake valve, exhaust valve, spark plug, stroke, and crankshaft.
a. The metal cover that seals the top of the cylinder
b. The valve that allows burned gases (waste products) to vent out of the cylinder
c. A solid metal into which the cylinder is drilled
d. The total distance that the piston moves from the top of the cylinder to the bottom
e. A can-shaped component that can move smoothly up and down inside the cylinder
f. The valve that allows the air-and-fuel mixture to be delivered to the cylinder
g. A hollow metal tube drilled into the solid metal engine block
h. The open area located above the piston, positioned at the very top of the cylinder (This is
where the air and gasoline mix and burn to produce power.)
i. Piece connected to the piston by a connecting rod (With the rod, this part converts the up-and-
down motion of the piston to rotary motion, which makes the car move forward.
j. Part screwed into a hole in the cylinder head and used to make sparks that will ignite the air-
and-fuel mixture in the cylinder and cause it to burn.
