Final answer:
Car and truck engines typically have four, six, or eight cylinders, which influence the vehicle's performance and efficiency.
Step-by-step explanation:
Normally, car and truck engines have either four, six, or eight cylinders. Internal combustion engines are a crucial part of automobiles and are designed to generate power by burning fuel, such as petroleum, in the presence of oxygen to produce a high-pressure gas. This gas exerts force on a piston, causing it to move, and powering the vehicle. The number of cylinders in an engine affects the vehicle's performance and efficiency, as each cylinder provides an individual power cycle during operation.
