Abstract
Abstract A fuel saving device for increasing the fuel mileage of a moving vehicle is disclosed. The number of miles per gallon of fuel is increased by the present invention through a device mounted on top of a vehicle, which device includes a housing having a length substantially equal to the width of the vehicle, an air intake at the front of the housing and a motor driven rotor having blades which are further driven by the oncoming wind pressure created by the moving vehicle. The device also includes means for deflecting the air from the housing over the remaining portion of the vehicle and positioned in cooperative relationship with the rotor to not only reduce air friction but also to create a propulsion of air at the rear of the housing to drive the vehicle forward. A motor means drives the rotor independently of the forward speed of the moving vehicle.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
a fuel saving device for increasing fuel mileage on a moving vehicle comprising: (a) a housing mounted on top of said moving vehicle, (i) said housing having an air intake opening at the front of said housing and an exhaust opening at the rear of said housing for the flow of air therethrough, (b) a motor driven rotor disposed within said housing and positioned in cooperative relationship with said air intake opening and exhaust opening of said housing so that said rotor rotates at various rotational speeds in response to a forward wind pressure generated when said vehicle is moving in a forward direction, and (c) rotor drive means for rotating said rotor at a greater speed than said various rotational speeds to decrease said forward wind pressure at said intake opening of said housing.
Claim 2
Dependent Claim
135 words
a fuel saving device for increasing fuel mileage on a moving vehicle comprising: (a) a housing mounted on top of said moving vehicle, (i) said housing having an air intake opening at the front of said housing and an exhaust opening at the rear of said housing for the flow of air therethrough, (b) a motor driven rotor disposed within said housing and positioned in cooperative relationship with said air intake opening and exhaust opening of said housing so that said rotor rotates at various rotational speeds in response to a forward wind pressure generated when said vehicle is moving in a forward direction, and (c) rotor drive means for rotating said rotor at a greater speed than said various rotational speeds to decrease said forward wind pressure at said intake opening of said housing.
