i mean from off state to ON State,the amount of diesel it reqiures to burn out.
I have never heard. But it can't be very much. There's a primer button back in the long hood area. Priming is necessary because the fuel runs back down into the fuel tank when not running. After priming for about 6 to 10 seconds, a start switch is flipped that turns the generator into a magnetic starter motor. The engine only turns over just a couple times (usually) before it fires and is pleasantly idling on its own. Starting can't require very much fuel. On the newer GEs and EMDs with auto shut down, these starting functions are all automatic electronically of course.
the injection systems only variable is for the control of rpms during operation. during the start up process rpms are less than operation. yet the system delivers the same amount of fuel as the lowest setting. the fuel system, much like any other machine, is a constant. feed rate and pipe i.d. do not change magically. to throw in more fuel than the cyclinder can take would be destructive. variances can occur during hard starting situations (cold climates). this is the same as the choke on a car. diesels do not have this as they employ whats known as glow plugs which are essentially little plugs inside the cyclinders that preheat the chambers making it easier to start. since locomotives do not use this technique, this is why you will see them idling when not being used in a cold environment. in essence, its a royal b***h to start one when cold. never the less, to accurately know the fuel consumption rate (gph) at start up, you will have to contact the manufacturer to see if these figures are available. highly unlikely they would have these figures as opposed to actual operational gph which is where the do their testing.
Very little. Less than it takes to run at power while underway. The fuel lines are only so big, and it can't flow fuel any faster than that. There is a myth that machines take a LOT of energy to start up. Some people say it takes as much power to start your PC as it does to run it for 30 minutes. The same is often said of fluorescent lights. That is not true - it is essentially never true. It is used as an excuse to avoid shutting the thing down. Why can't they? Because the pipe or wire supplying the fuel/energy is only so big. If a PC took that much energy to start up, it would trip the circuit breaker. The energy also would have to go somewhere, and energy always goes away as heat. A massive surge of startup energy would be a massive surge of heat, which usually burns or explodes a thing. So no -- devices generally do NOT use massively more energy to start up than they do to stay running. Some times might have a startup surge of double, or perhaps triple - such as a hard drive or compressor spinning up. But nothing more than that, and only for an instant - too fast for most circuit breakers to trip.
