  • High efficiency vehicle and engine
    Patent number: 5819702
    Abstract: The efficiency of a vehicle having a body and a reciprocating piston four-stroke internal combustion engine is increased substantially by greatly reducing the size of the engine relative to the weight of the body. The great reduction in engine size relative to the weight of the body causes the engine to operate in a much more efficient range during almost all of the time of its operation. Peak power needs are satisfied by turbocharging and varying the compression ratio.
