No mention of diesel engines in that article. The statement that 99% of gasoline does go through combustion doesn't hold true for diesel. Even if it's close to that, not all of the combustion of diesel fuel happens in the chamber. Diesel fuel burns slowly, and some combustion happens after...

So, a gas that is below LEL can still be lit with a spark or flame?

I had noticed the higher ignition temp of methane and thought to myself "if I could harness cow farts, I'd be set." But if the surface temp. inside the chamber is well over (or even approaching) 800°C, then it would seem that ANY gas that was mixed with the intake air would pre-ignite. I did...

Seems to me that the stated use exactly matches the technology. I didn't see anything in the article (that SF posted) about replacing cruise missles. They want to replace the MK45, a sea-to-land gun. Also, while the test resulted in 10.6 Megajoules, the gun is designed for 32 Mj, and...

If it is not difficult, then please tell me how. There are smoke suppressors in the additives they put into #2 diesel before it reaches the pumping station. I don't know for sure how they work, but I doubt they help the combustion. After all, the point of all of this is to cause a more...

I would think that all three of those factors would have an influence. Problem is adjusting those factors. Increasing the amount of time in the chamber means you advance the timing. Thats not a good idea in and of itself, but they (the people trying to sell these electrolyzers) actually...

Let me start off by saying that I understand conservation of energy and the laws of thermodynamics. I know you can't use water for fuel, and you can't power a vehicle soley on hydrogen produced by an onboard electrolyzer. But... I have read quite a few claims that using an onboard...

WOW! What sir, if I may ask, do you believe IS my reason? I don't know how many different ways I could possibly say this: I never even suggested MOI BE neglected! The only reason I breezed over it was, first of all, you had already mentioned it. And second, The fact that HE considered drag...

When I said "one would assume..." I meant that, given his consideration that drag and friction are negligible, I would assume that he also considers MOI negligible. Again, only he knows what his tolerances are.

Look, this is silly to argue about. You're acting as though by not factoring in MOI in my explanation that I am discounting MOI altogether and calling you a fool for suggesting it. If MOI isn't classified as a resistance, then so be it. It IS opposing the acceleration of the vehicle, which...

Ok, so the moment of inertia is opposing the acceleration of the vehicle. "Resistance" or not, I'm not going to argue semantics. My original reply was a direct answer to the very specific question posed, "Mainly what I am asking for is an equation that would allow me to convert torque into...

If you read my last paragraph, I do acknowledge that NO friction, resistances (MOMENT OF INERTIA BEING ONE OF THEM) or inefficiencies were factored in. However, now that you mention it... While I would not necessarily consider moment of inertia "negligable", I certainly think it is far less a...

The simple answer to your main question would be Newtons second law: acceleration = force / mass. First, let's convert all measurments to metric. 7000 lbs = 3175 kg. 14 inches (the radius of your tires) = .3556 meters. 88 inches (circumference of tires) = 2.235 meters. Lets first...

thanks for your replies guys. i do understand how to achieve a particular wattage and amperage, and the wire comes labled with its resistance in ohms/foot. ultimately, i need to decide what wire i want to get, as there is a huge variety. what i need to know is, will 1 foot of 2 ohm/foot...

newbie here, I've been searching many forums and cannot find the questions/answers I am looking for (close, but not quite). so, I am going to ask my question in a very specific, detailed manner. i want to use nichrome wire to make 8 heating elements. they will each be a single strand...
