The Electromotive Strategic Power Assist Hybrid design delivers smooth, high power performance while decreasing harmful exhaust emissions and maximizing fuel economy. Lets look at how the Electromotive system executes these classic hybrid goals with exceptional efficiency.

Mechanically Simple, Electronically Sophisticated

Other parallel designs use complicated clutches, gearboxes or differentials to couple the engine and the motor to the drive train. Such mechanical linkages are heavy, expensive and can be unreliable. They also contribute to `parasitic drag' which robs horsepower from your engine, horsepower that could used more efficiently for propulsion. With the Patented Electromotive System, the engine and electrical motor are coupled in a simple, seamless, reliable design.

Hybrid developers have experimented with designs that operate the internal combustion engine (ICE) and the electric motors at different times. Some use electric motors for starting and low speeds, some use the ICE for highway use. Some have attempted to operate them together but proper monitoring and control was problematic. Problematic until now.

Electromotive tested a variety of power train combinations and powering schemes. The winning combination is the Strategic Power Assist. With this system, the electric motor is controlled to output power under certain operating conditions to assist the ICE. In particular, the electric motor provides a "Load Leveling" function that results in ultra-efficiency. This complementary system matches the strengths and weaknesses of both electrical and fossil fuel propulsion to provide an overall power plant that performs significantly better than either an electrical motor or an internal combustion engine alone.

During high load, the electric motor produces `free' torque to overcome the need for the ICE to satisfy rapidly changing power demands. This is the strength of the electric motor. Once conditions are met and favorable, the ICE operates at peak efficiency in the "Sweet Spot" that we discussed earlier. While operating during the Sweet Spot and other conditions that produce excess power, the electric motor resupplies the batteries with energy making this system `Charge-Sustaining'. Also a smaller engine may be used because of the additional torque provided by the electric motor which of course contributes to improved fuel economy.

Some hybrid enthusiasts feel that the more the vehicle operates on electricity the better it must be for economy and emissions. Some hybrid systems attempt this but in reality, without comprehensive engine monitoring and computerized real time adjustments, the starting and stopping of the ICE in conjunction with operating the engine under unfavorable load conditions actually hurt emission reduction. The Electromotive Strategic Power Assist System utilizing small assisted engines running `good and lean', monitoring all engine functions while seamless living in the Sweet Spot, produce impressively low emissions and significantly reduce fuel consumption.

Here is a Test of the Electromotive Strategic Power Assist System. The test vehicle is a `93 Honda Civic VX with a 1.5 Liter engine. The Experiments were conducted at the EPA Test Lab.

Test Results with the Electromotive Strategic Power Assist


NOTE: The test result graphs may seem similar, however the unassisted test graph has a 0 to 36 mg/s scale on the right, whereas the assisted test graph uses a 0 to 8 mg/sec scale.
Conclusions:

• The peak transient emissions were dramatically reduced.
• The low-end, off throttle response is smoother and faster
• The use of a small amount of electricity to augment the ICE while idling is the most energy efficient.
• Tail pipe emissions are reduced as a result of using the electrical motor to `load level' the engine.

Until sometime in the future when newer technologies can be developed, the Hybrid Electric car with the ICE running at near perfect conditions thanks to advanced computer controlling, will reign as the most efficient and environmentally conscience vehicle available. The Electromotive Strategic Power Hybrid System can make this a reality with its ease of fitment into current vehicles or in retrofitting. The engine/motor/system management computer is the key to the success of your model. Electromotive has been perfecting its system since 1981 and will be available at fair and reasonable prices.
