FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

Data was collected with the stock ignition system with a representative ignition strategy, followed by comparison to a drop-in replacement with the TPS nanosecond pulsed power ignition system (coil and plug). The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. Conclusions. slow charge.

EV myths busted: Are electric vehicles actually good for the environment?

Drive Electric

Because EVs run on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components in ICEVs. In comparison, EV engines run on lithium batteries. The best part about this method of repurposing is that the next generation of EVs would in turn be powered by a ‘cleaner’ grid.
