According to a report in Autobloggreen (http://www.autobloggreen.com/2009/02/25/geneva-preview-lotus-to-unveil-omnivore-concept-engine/), Lotus Engineering will unveil its Omnivore concept engine at the Geneva Motor Show. The Omnivore is a flex fuel engine that is designed to extract the maximum amount of work regardless of what type of fuel is used.
The concept engine uses a mono-block layout with a single hunk of metal comprising the cylinder block and head and no poppet valves. Instead the ports are exposed by the piston's motion. Variations in timing between intake and exhaust are achieved by valve in the exhaust port that traps the exhaust. And it is a two-stroke design with an air assisted direct injection system.

The goal of the project is to allow engines to go as far as possible on every gallon fuel regardless of the fuel type. Ultimately this design should even be able to accommodate diesel-like HCCI combustion (http://www.autobloggreen.com/2007/08/26/abg-tech-analysis-and-driving-impression-gms-hcci-engine/).
