    The problem with Diesels in cold weather has nothing to do with the temperature of the air being taken in (The colder the better, as far as internal combustion engines are concerned), but it has everything to do with the fact that Diesel fuel has the nasty tendency to turn to jelly in very cold weather.

    not true Gyrene, it has everything to do with the temperature of air being taken in, because Deisel engines have no spark plug to ignite the fuel, a combination of what is called a glow plug, and the rapid compression of air is intended to heat the air to over 700 degrees F. if the origional air is very cold, <0 F. than those two actions will not be enought to heat the air and therefore start the engine

  2. Deisel engines use something called a glow plug, instead of a spark plug, which is used in petrol engines. THe difference is that the glow plug minimally heats the air coming into the engine, the majority of heat to ignite the fuel is created when the air is compressed very fast and very hard. This compression is intended to heat the air to over 700 degrees f. Often times in cold areas, most often in WWII on the eastern front, the air would be too cold and the compression of the air would not cause sufficient heating, therefore the deisel would not ignite, and the engine would not start. In situations like this, it was necessary to use a specially designed starter to heat the air, and because these were few and far between, it would sometimes take hours just to start a small company of armor or transport.

    The advantage of deisel over petrol is taht first, they get much better mileage, and therefore can go farther on each gallon. Also a deisel engine has far fewer moving parts, and therefore requires less maintenance.

    "A bigger question is why the pre-invasion aerial bombardment was planned so far back from the headlands over the

    beaches. As it was, the preponderance of the bombers struck miles inland,tearing up orchards and killing livestock but precious few Germanans." -gunnergoz

    --------------------------------------------

    The reason the bombardments happened inland was so that the airborne paratroop divisions would be able to sucessfully land.
