  • Compressed air engine and power train system
    Patent number: 8893488
    Abstract: An engine and drive train system suitable for personal or commercial transportation vehicles. The system converts the expansive energy of compressed air or gas into mechanical energy to produce motion or force. The engine of the present invention further uses the intrinsic kinetic energy of the vehicle in motion to generate and store compressed air or gas for in-situ or later use. The engine may also be used for braking by the introduction of high pressure air or gas at maximum displacement.
    Type: Grant
    Filed: January 7, 2013
    Date of Patent: November 25, 2014
    Inventor: Frederick Michael Shofner, II
