Modern combustion engines become increasingly economical and clean. Engine developers, however, are now facing the technical conflict of whether fuel consumption or exhaust gas emission is to be further reduced. This Gordian knot might be cut by chemists' and engineers' further development of sophisticated fuels that help optimize combustion in the engine.
