Question

Which of following is the most accurate description of a piston in an internal-

combustion engine?
A shaft that converts the up-and-down motion into a rotary motion
A plug that protrudes through the cylinder head and makes sparks that ignite the
air-and-fuel mixture
A can-shaped component that moves smoothly up and down and is the main
moving part
O A hollow metal tube drilled into the solid metal engine block

Answer 1

C. A can-shaped component that moves smoothly up and down and is the main

moving part
