Which statement is true regarding an engine's longer stroke?

Explanation:
A longer stroke in an engine generally correlates with an increase in torque output compared to a shorter stroke engine. This phenomenon occurs because a longer stroke allows for a greater displacement of air and fuel during the intake phase, which can lead to more energy being produced during combustion. Torque is essentially a measure of rotational force, and with a longer stroke, the engine can produce more leverage and enhance its ability to turn the crankshaft. This results in a stronger torque curve, particularly beneficial in scenarios such as towing or hauling where low-end power is advantageous. In addition, the longer stroke often combines with a larger cylinder bore to enhance overall engine efficiency and responsiveness, further contributing to torque production. While other factors, such as engine design, induction methods, and tuning, also play significant roles in torque output, it is generally accepted that a longer stroke can contribute positively to an engine's torque capabilities.
