Crankshaft Reluctor Wheel Caterpillar 6366284

The Crankshaft Reluctor Wheel also known as a tone wheel, is mounted on the crankshaft of an internal combustion engine. It features a series of precisely spaced teeth or notches that are used to generate signals for the Engine Control Unit (ECU). As the crankshaft rotates, the reluctor wheel's teeth pass by a sensor, producing a signal that is utilized for ignition timing, fuel injection, and engine speed calculations.Attributes:• Precisely indicates the crankshaft's position and speed, the reluctor wheel enables the ECU to optimize combustion, improve fuel efficiency, and reduce emissions• Provides smoother engine operation, reduced vibration, and improved overall drivabilityApplications:The Crankshaft Reluctor Wheel is mounted on the crankshaft so that as the crankshaft rotates the magnetic sensor is triggered by notches in the reluctor ring. The magnetic sensor provides position information to the electronic control module, which governs ignition timing.
