'hot bulbs' and glow plugs are only used before the engine is started to preheat the cylinder. kerosene is also known a 'diesel #1' because it is basically 'diesel #2' with the 'waxes' and other lubricating chemicals that are part of the fuel removed. it 'gels' or starts thickening to a Jello consitancy at a lower temperature (-40 F versus -20 F). They Probably use Detroit Diesel Engines. Detroit (GM) has been making the same basic engine design since before WWII. they were used in WWII American tanks, and most American tanks until the M-1 which uses a 'gas' turbine (still burns diesel, but can burn about any hydrocarbon based fuel.)
Back in the 60's and 70's, 'hot rodders' started modifying 4 and 6 cylinder Detroit 'blowers' to use as superchargers on Gasoline V-8 engines. On the diesel engine, it is used to do what the crankshaft does on a small gas 2-stroke, and 'push' the exhaust out of the cylinder while filling the cylinder with fresh air. the incoming charge is around 4psi, so it's not considered 'supercharged.' In a 'supercharged' engine, the cylinder is filled with a charge at least 7psi above atmospheric pressure. The '92' series Detroits (all 'V's', V-6 or V-8, 92cid per cylinder) used a TURBOCHARGER feeding into the'blower' to supercharge the engine.
If you truly want to be bored to death about how diesels work, e-mail me. Spent about 1/4 of my classes in Auto diesel tech on How diesels work. Cummings,Caterpillar, Detroit,Mack, and the 'off-brands' like Lister (air-cooled 4-strokes), GM, Isuzu, Mercedes....
