Lotus Omnivore Engine 1st Test Phase Complete

British carmaker Lotus announced it has completed the first testing phase of its new two-stroke engine, dubbed Omnivore, successfully running the engine on gasoline.

According to Lotus, at 2,000 rpm and up to approximately 2.7 bar IMEP (Indicated Mean Effective Pressure), the ISFC (Indicated Specific Fuel Consumption) proved to be 10 percent better in terms of fuel economy than the best current gasoline engines. As far as emissions go, the Omnivore achieved 20 ppm NOx at less than 2.3 bar load.

These impressive results represent an important step-forward in Lotus Engineering’s strategy of developing an array of more efficient multi-fuel combustion systems," Simon Wood, Lotus Engineering technical director said.

"Omnivore lays the foundations for a novel and pragmatic vision of a variable compression ratio engine concept suitable for production. A multi-cylinder version is practical for a wide variety of vehicles and offers greatest benefit to C and D class passenger cars which can take advantage of
the low cost architecture and significantly improved fuel economy and emissions.
"

The Omnivore uses variable compression ratio system and two-stroke operating cycle with direct fuel injection that allows it to increase fuel efficiency for sustainable alcohol based fuels.

For the future, Lotus plans to begin testing how the engine works on alternative renewable fuels (ethanol or methanol).

"We are continuing our discussions with other manufacturers and eagerly anticipate the development of multi-cylinder demonstrations of this revolutionary engine configuration,” Wood added.
