  • Hybrid motor unit with energy storage
    Patent number: 3986575
    Abstract: An automotive engine unit comprises an internal combustion engine adapted to meet the power requirements of a vehicle under steady speed running conditions, a hot air turbine unit of higher power output than the internal combustion engine adapted to meet the additional power requirements for accelerating the vehicle, an air compressor driven directly or indirectly by power supplied by the internal combustion engine, and an air storage reservoir. During acceleration of the vehicle, air from the reservoir is fed to the turbine through a heat exchanger where it absorbs heat from the exhaust gases of the internal combustion engine.
