How can a compression stroke be shorter than a power stroke? Are the con-rods variable length or the crankshaft morphs?
Also, why haven't gasoline engines been DI from the beginning, with no spark plug?
Last question, what is the difference between OTTO and Atkinson?
It seems to me the most efficient car would have a puny motor (3 cylinder 1L perhaps) and a turbo charger. Make this diesel with electric assist and regen and you would have one heck of an efficient vehicle.
