  • Hybrid vehicle and energy storage system and method
    Patent number: 6834737
    Abstract: A system for providing a hybrid vehicle with a practical source of auxiliary power. The system includes two electric motor/generators connected to each other in such a fashion so that when one electric motor/generator functions as a motor, the other becomes a generator with their roles being reversed depending on whether the system is in an auxiliary power mode or energy storage mode. Connected to one motor/generator is the vehicle drive train. Connected to the other motor/generator is a pressure energy storage system, which in the energy storage mode converts the force of rotation into pressurized gas for storage in an energy system and delivered in the form of electric current by the one motor/generator, and in the energy delivery mode converts the stored energy of the energy storage system into electric current for delivery to the one motor/generator which is part of the vehicle drive train to provide auxiliary power for practical hybrid vehicles.

  • System for monitoring and improving motor vehicle operating efficiency
    Patent number: 4280457
    Abstract: A system responsive to engine manifold pressure for monitoring engine operating efficiency and reducing engine load during periods of low operating efficiency is disclosed. The system includes a switch which actuates a first relay when manifold vacuum pressure drops below a threshold level. In this condition, the first relay activates a time delay relay in the control circuit of the air conditioning compressor to remove this load from the engine after a first interval and maintain it in the off condition for a second interval.
