| 20080229743 | TURBOCHARGER SYSTEM - A turbocharger system for an engine includes first and second turbochargers, having air intake impellers which rotate in opposite directions. This enables the first and second turbochargers to be mounted on opposite sides of an engine in a symmetrical fashion, resulting in an aesthetically pleasing arrangement as well as air intake and exhaust piping being of the generally same length and configuration to optimize engine performance. | 09-25-2008 |
| 20080236162 | Supercharger control system - A compact, solid mount unit supercharger control system is installed at the bottom front end of the engine, directly onto the crankshaft of a vehicle. An accessory drive belt around the accessory belt pulley of the system rotates continuously to keep vehicle accessories (alternator, water pump, etc.) operating. A second belt around a larger pulley drives the supercharger blower. A switch mounted with the vehicle dashboard controls engine generated electrical current to the system. In order to activate the supercharger, the switch is turned on. Electric current flows to the system and energizes an electromagnet, creating a magnetic field 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. When activated, the supercharger forces air into the engine cylinders for greater horsepower output with fuel/air explosions within the cylinders. This provides greater acceleration and top-end speed for the driver. If the driver does not require extra power and performance, the switch is turned off, stopping the flow of electric current. This shuts down the magnetic field, causing the pulleys to be disengaged and disconnecting the supercharger, while still allowing the crankshaft to operate the other accessories. In this mode, gasoline consumption is reduced and there is less exhaust being emitted. The control system of the present invention also reduces wear and tear on the crankshaft and other engine components for greater reliability and extended engine life. It also reduces stress and wear on the supercharger itself, while keeping it running cooler. | 10-02-2008 |

| 20090260357 | SERVO-ACTUATED SUPERCHARGER OPERATING MECHANISM - The present invention provides a servo actuated operating mechanism for a lobed rotor positive displacement supercharger combining a low cost and capacity electromagnetic clutch with a small oil pump internal to the supercharger unit. The oil pump supplies on demand oil pressure from oil in a hydraulic clutch housing or the supercharger timing gear case and acts as a servomechanism to actuate an internal hydraulic clutch. The hydraulic clutch can be engaged over a much wider range of speeds and loads than is possible with an electromagnetic clutch alone. The addition of an accumulator enables even faster engagements. The electro-hydraulic servomechanism provides improved highway fuel economy relative to an electromagnetic clutch as the engagement speed could be moved to a higher rotational speed (rpm).
