yes, it's true that fuel only burns as a vapor and that 98% or more of the fuel is vaporized and burnt in the engine, but just like with propane injection on a diesel working by making the fuel ignite faster and burn faster, increasing the downward pressure on the piston increases torque and the power to fuel used ratio improves because there is more flame and pressure at the top of the stroke, it would be good to know how warm/thin the fuel is as it passes through the injectors, but that is hard information to gather.
