Getting a diesel started if you live on a hill is easy, roll it down the hill, gently slipping the clutch ( we are NOT bump-starting which could cause problems ). After a short while, stop the car on what little brake power you have, and turn the key.
By turning the engine on the way down, you are compressing the air in the cylinders, but not enough to ignite it. This compression heats up the cylinder a little, and will help starting ( ie. you're being a rubbish glowplug ).
Done this before when I had a couple of dodgy plugs, worked a treat until I managed to replace them.

hahaha some funny stories here.[:D] I have also witnessed the amazing 10,000 rpm diesel. Funny thing is you cant even switch them off until they have burnt the 'fuel'. Have seen a good one with a can of 'choke and carb cleaner' - big can shake, sprayed for probably 1.5 secs into intake before it got to engine (turbo), cue drop can and run in opposite direction!!
Referring to "light the blue touch paper . . . " The Volvo diesels i describe (everything from 6 litre straights to 25 litre V12's) use air preheating for cold starts. They are all direct injection with unit-injectors and very high pressure pumps. The preheater is basically a square box through which the induction air is forced (they are turbo-charged as well). The box contains an electrical heating element which heats up the induction air. So Phil's description is far off what the professionals use.

In my truck driving days of the early seventies we didn't have glow plugs (eeh by gum etc). The Ford trucks had a 'cold start' lever which was accessed through the radiator grill and needed a second person to operate it. The Bedfords didn't even have that. Most people ignored the cold start lever and there was much cranking over in the early mornings and clouds of white smoke for breakfast. You knew if the cold start lever was stuck by the clouds of black smoke in your mirrors and the dirty looks of passing car drivers. A few years into the job we got new Transits for the 'express' runs and they had these wonderful glow plugs and the engine stopped when you turned the ignition off (we had to make do with the stop cables in our trucks, many of which didn't work and we had to stall with the brake pedal). High tech stuff.

My boat engine has a Lucas Thermostart device which consists of an electrical element and a pipe from the injector leak offs, this is cunningly placed in the inlet and the starting drill is, press button for ten seconds then crank starter in four second bursts, diesel hits the hot element and produces gouts of flame in the inlet tract, inbuilt burning rag! still produces clouds of smoke on startup though.

My introduction to diesel started back in 1974 with a Ford 9 seater Transit fitted with a 2.5 York engine. It didn't have glowplugs, just a reservoir of diesel high up on the bulk head. When a switch was pressed, a coil fitted in the manifold glowed red whilst diesel dripped onto it. After a minute the starter was used and if compression was good, the engine fired with clouds of smoke. Try starting with the air cleaner removed and the flames coming from the manifold were alarming. After a couple of years I changed the head for a new model with holes for glowplugs. The plugs were wired through a relay, straight off the battery. Preheater time was just a matter of trial and error. To stop the engine, a knob similar to a choke cable was used.

My parents have a late 1950's Fordson diesel tractor that starts (sometimes) using a similar method. There's a button near the fuel tank which has to be pressed repeatedly and squirts diesel onto a heating coil in the manifold. I have heard of farmers starting old tractors by stuffing a rag soaked in diesel into the manifold then lighting it !

Yep, my grandad had one of those. He said the only way it would start on cold/damp mornings was to take the spark plugs out the night before and leave them in the aga oven until required.
Before then there were those tractors that needed a point on the manifold heated with a blowlamp for several minutes until they would consider starting....

The system NiSk refers to was also used in the 10-and12-litre Turbo 6 engines in trucks and coaches.These carried dire warnings
of fatal mechanical and/or personal damage if an easy starting spray was used due to the eplosive consequences when the spray vapour came into contact with tht heating element.Easy start and any kind of heating device......Definitely not!

Beezer and Nick - I've still got a 1952 Ferguson TE20 petrol/TVO (Tractor Vapourizing Oil = paraffin). It runs OK on petrol but isn't very powerful on paraffin, whats more, paraffin costs more than petrol over hear so the whole thing is just for the sentiment of it!
What really shook me, especially concerning the difficulty there is in getting parts for "recently deceased" Citorëns, was that while on holiday in the UK a couple of years ago I went into the combined Post Office /General store/ Agricultural workshop of the village where my parents lived in Cornwall (Rumford) and casually asked if they had a head gasket for a TE20. Imagine my surprise when they offered me a choice of Low compression petrol, High compression petrol or Petrol/TVO! Amazing - for a vehicle that was built over 50 years ago!
