  1. Yes , compression ignition with more energy dense fuel in a Diesel , hence the Lower Fuel Ratio . However Diesel fuel burns Slower , AND , diesels do not have an Advance curve , as such . What happens is , the Injection Cycle STARTS earlier and runs Longer at High Output demand . THAT is the advance , right there . And the Longer Injection Cycle keeps fuel going in longer needless to say . The Fuel Injection Pressure on ANY Diesel FAR exceeds any pressure you can get inside the cylinders . Up to 1200 plus Bar . Positive displacement fuel delivery . A 16 litre Truck Turbo-Diesel making 600 bhp and 2850 ft-lb torque can get around 2.4 km per litre economy under load . But up to 12 -14 km per litre just pushing the Prime Mover itself . Americans would know that as the Tractor Unit . Weighs 7 - 10 tonne and uses less fuel than the Family car . Pretty good fuel figures .
