In the structure of a diesel stacker engine, what is the machine part that transmits the reciprocating motion of the piston to the crankshaft?

The machine part that transmits the reciprocating motion of the piston to the crankshaft is the connecting lever, often referred to as the connecting rod. This component plays a crucial role in the operation of an internal combustion engine. The piston moves up and down within the cylinder as fuel is ignited, creating pressure. This linear motion is then transferred to the crankshaft via the connecting rod.

The connection between the piston and the crankshaft allows the rotational motion of the crankshaft to be generated, which ultimately drives the vehicle. This is a key aspect of the engine’s mechanics, as it converts the linear movement generated by the pistons into usable rotational force needed to power the drivetrain.

While the piston rod, cylinder head, and camshaft are all essential parts of an engine, they serve different functions. The piston rod is directly associated with the piston itself, while the cylinder head contains the combustion chamber and valves. The camshaft operates the opening and closing of valves but does not directly link the piston to the crankshaft. Thus, the connecting lever is correctly identified as the component that performs this essential function.
