In most cases, an engine is designed to rotate in a specific direction, which is determined by the arrangement of the engine's pistons, valves, and other internal components. However, some engines can be rotated in the opposite direction by changing the timing of the spark plug ignition or fuel injection.
If you need to rotate the engine in the opposite direction for maintenance or other purposes, you can use a special tool called a "reverse rotation adapter." This tool changes the direction of rotation by altering the timing of the spark plug or fuel injection.
As for how a reverse gear works, it is a gear in the transmission system that allows the vehicle to move in the opposite direction. In most vehicles, reverse gear is engaged by shifting the transmission into a separate position, which changes the direction of power flow to the wheels. This causes the vehicle to move in the opposite direction of the forward gear. The reverse gear is typically slower than the forward gears, allowing for more precise maneuvering in tight spaces.
