HP2g.com 110mpg V8 Engine Motor
What makes the HP2g get such incredible gas mileage without a significant loss of power?
For lack of a better description: marriage and frugality.
HP2g technological achievement has been the marriage of an electric motor into his E85-powered V-8 internal combustion engine, and controls that allow the combined powerplant’s output to range from more than 400 horsepower to as little as 15 horsepower, depending on what is required at the time by the accelerator.
This phenomenal range of energy output is accomplished by the HP2g E-85 fueled engine can transition from running on all eight cylinders down to firing on just one.
We in the auto industry call it “variable displacement” — shutting down normally half of an engine’s cylinders when not under load — to improve fuel economy. But unlike other designs, HP2g has discovered a way to vary which cylinders are shut down, so that when his engine is operating on a single cylinder, the cylinder that is firing rotates between the eight in his engine. This avoids excessive carbon buildup in part because we are using clean-burning E85 ethanol as his fuel source instead of a standard gasoline blend.
HP2g powerplant also picks up added efficiency because his incorporated electric motor — greatly responsible for the 500 ft. lbs. of torque the powerplant generates — operating on a pulse basis, instead of at what is called full saturation. In other words, the electric field used to generate power to the vehicle’s wheels can rapidly cycle on and off as required, saving energy. The vehicle uses just two “spiral core gel” batteries, common in racing, one on each side of the vehicle, and also reclaims some energy from more established manners, such as regenerative braking, which captures energy that would otherwise be lost as a vehicle decelerates.
The HP2g design picks up added efficiencies because of tight tolerances and sturdy design that reduces engine vibration and heat, all of which drain energy output from traditional vehicles.
Also the HP2g has log more than 22,000 miles of real-world driving on his 3,250 lb. 1987 Ford Mustang over the last 18 months with an average fuel economy of 109.7 mpg.
Standard EPA testing on the vehicle in Cleveland in May confirmed that — without the benefit of a catalytic converter, which his design does not require — the Mustang’s tailpipe emitted 86.6 of hydrocarbons and 0.46 percent carbon monoxide, both well below the newly imposed EPA standards for all automakers.
