The 85 kW / 115 PS gasoline-fired engine is the first of its kind to be combined with a four-way catalytic converter and installed in the up! It also comes with a gasoline particulate filter. With a pressure of 350 bar (high for a gasoline engine), the fuel mixture is injected directly into the combustion chambers.
Hydrogen is not currently an option for small vehicles such as electric scooters and motorcycles, since the pressure surge during refilling would be too great. This means that POWERPASTE can offers a range comparable to—or even greater than—gasoline. POWERPASTE, on the other hand, the researchers suggest, would be ideal.

If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. The authors compared these results to a range of fuel economies from an EV that was charged from electricity produced from the US mix and a range of natural gas turbines with varying efficiencies. —Curran et al.
