The idea of heating I assume is to increase the temperature of the combustion chamber.

I think the other issue is that if the entire block is SO cold that all heat created by the glow plug is immediately absorbed by the very cold block, it's going to be hard to start.

Notice, even in a 240D with low low compression, if you warm the block to even 60 degrees, it will fire up.

The heat in the combustion chamber is not robbed, so the diesel principle of compression-ignition combustion can take place :-)

Used to be pretty common when I was doing off-road heavy equipment (cranes, dozers, graders, etc.). We'd have an old 30 gallon oil drum, cut off to about 6-12" tall, a hole cut in the side and a long hook to move it about with. Fill the drum about 3-4" with charcoal, light it, let it burn down and then slide it under the engine block (we had a thick mesh over the charcoal to stop any flames). We called it a "Cummins Pre-heater". We usually reserved this wonderful task to whoever was in the "dog-house" that week. Miserable arsed job. Standing around freezing, surrounded by the pungent aroma of charcoal, old engine droppings and whatever the operators managed to run over the day before.

I remember a guy on another forum mentioning pointing a heat gun into the intake of his Unimog to get it started in cold weather.

Yeah.......



But hey it worked

I had no trouble starting it the night before after it sat for 8 hours and i've always been good down to around 15 F. However yesterdays -2 for 10 hours was just a bit too much. At first I thought my battery was drained (Slow cranking) but I quickly realized that the 15W 40 was so thick that it was inhibiting the engine from turning. (Yes I know I should be running a lighter weight oil but I didn't realize until it was too late that it would be getting this cold) Even worse I never got around to fitting a new plug to my block heater.

Thankfully the bucket was nearby and there were plenty of dry sticks to be burned. The flames are low on purpose (I only wanted hot air hitting the bottom of the oil pan, not flames) After 5 minutes I tried and got a cough and decided to keep going. Ten or fifteen minutes later I tried again and the starter turned as fast as a summers day and she fired on the first shot without hesitation.

I wired a new plug to my block heater and this morning I was off after 2 seconds of cranking

Back in the day on college Christmas break 2 friends and I drove cross country to ski Vail. On of the guys went to SoCal to pick up a friend's VW Beetle to drive back East. An overnight stay in Vail thickened the SoCal oil to a sludge so the car wouldn't start. Had to call a tow truck to heat up the oil with a heat blower to start it. What did we know, we were college kids...

Experience is often a hard teacher.

I noticed the picture of the Mongolian Engine heater isn`t here in post #1, so here it is, found it on Google. Can`t make the picture any larger, and clicking on it just get`s you back in this thread.

I have been looking for one of these engines for a long time. Where can I find one?

Google is your friend. here is a boat load of them for you.

https://www.google.com/search?q=perkins+4+108+diesel+engine&biw=914&bih=610&source=lnms&tbm=isch&sa=X&ei=TS9tVJmPOuWbigLi_IAg&ved=0CAcQ_AUoAg


Actually looks like they were used in a lot of boats.

Check e-bay and CL.

There's a kerosene engine heater for sale near here:

ANTIQUE KEROSENE AUTO MOTOR HEATER ENGINE WARMER

I inquired, owner says it's mostly just decoration and he doesn't feel it would be functional, or safe.

I've also seen engine warmers for warming airplane engines on remote Alaska runways, looked like a Primus stove with some metal dryer ducting to direct the heat into the engine cowl.

Might be safer and more reliable than building a fire under a vehicle.

Yup, they're called Herman Nelson Heaters. There are different sizes.
That's what most use for heating trucks and industrial equipment too.

Had a bad glo plug last winter, singles or teens (F). Used a small propane grille and an aluminum cookie sheet to get some heat under the engine, got it toasty. The propane bottle got REAL cold.

PNW, I long for thee. My heart briefly lived in SFO, but I hear it's gotten extra douchey, so I've come around.

Come on down. We got 8" snow last year, getting that much was a pretty big deal.
