Omnivore concept engine by Lotus

Lotus developed an single-cylinder alcohol-fueled engine going to be shown at the Motor Show in Geneva. It takes the idea adding lightness a bit too far, it's pretty cool, amazing to have the lawnmower poses an 'Engineered by Lotus' sticker.

Mike Kimberley, the Chief Executive Officer of Group Lotus plc affirmed: 'We are delighted to unveil this major milestone in the development of an engine configuration for a new breed of more efficient multi-fuel engines. The automotive sector is focusing on its environmental obligations to improve efficiency, minimise reliance on fossil fuels and reduce harmful emissions and Lotus continues to be an industry leader through our work on all aspects of future fuels. Sustainable alcohol based fuels have the potential to reduce the overall CO2 footprint of internal combustion engines towards zero and for this reason, need to be embraced as future fuels for road transport.'

In this agreement with Orbital Corporation Limited Australia and Queen’s University Belfast, with DEFRA/DECC / DOE NI sponsorship via the programme Renewables Materials LINK, Lotus Engineering is now in the ultimate stages commissioning the single-cylinder Omnivore research engine. This utilizes the fuel injection Orbital FlexDI™ system that makes fine fuel in-cylinder preparation that's irrespective of the fuel type, plus together having air pre-mixing it allows efficient 2-stroke combustion plus low-temperature starting, offering high tech HCCI control singular opportunity.

Geraint Castleton-White, the Head of Powertrain at Lotus Engineering affirmed 'The absence of poppet valves in two-stroke engines makes the incorporation of a variable compression ratio system relatively straightforward. Our research into these systems on four-stroke engines has led us to the conclusion that while thermodynamically it is a desirable technology to incorporate, practically it is very difficult, particularly taking into consideration production feasibility. This two-stroke engine could solve these practical difficulties and simultaneously permits a much larger range of compression ratio adjustment, with the potential to perform at a much higher efficiency when running on renewable fuels.'
