Abstract
Abstract A supercharger control system is installed at the bottom front end of the engine, directly onto the crankshaft. An accessory drive belt around the accessory belt pulley rotates continuously to keep vehicle accessories operating. A second belt around a larger pulley drives the supercharger blower. When the dashboard mounted switch is turned on, electricity from the engine energizes an electromagnet, which compels engagement of the rotating accessory pulley with the supercharger pulley by means of a slide plate. The belt around the supercharger pulley then rotates, operating the supercharger. If the driver does not require extra power and performance delivered by the supercharger, the switch is turned off, stopping the flow of electricity. This shuts down the magnetic field, causing the pulleys to be disengaged and disconnecting the supercharger, while still allowing the crankshaft to operate the accessories.
