However, this stop/start function builtin will certainly save a lot of fuel, because you do need to inject Diesel into the cylinders to keep the engine alive. pro and con with the system then, however, I do see why they omitted the auto start/stop function in Diesel models. quote "The power output of a diesel engine is controlled by regulating the quantity of fuel that is injected into the cylinder. Because the engines do not need to control air volumes, they lack a butterfly valve in the intake tract. " [/QUOTE]
