Diesel engines, unlike gas engines do not have any spark plugs. The reason that they do not need a spark plug is because in diesel engines, the air is compressed much, much more than in a gas engine. The more that you compress the air, the more that the air is heated. Diesel engines have so much compression that the air inside of your cylinder becomes super heated and there is no need for a spark plug. The air is so hot that when the diesel fuel is injected into the cylinder, the diesel fuel ignites and the piston is pushed down via the "explosion" that takes place when the piston reaches tdc(top dead center).
Because of this, diesel engines need to warm up. This is why diesel engines have glow plugs. The glow plugs warm the block and help the engine to heat up faster.

What can cause white smoke from a diesel?
Moisture in the exhaust, or a cold running engine.
Is running a diesel engine for 5 minutes enough of a warm up in cold weather?
yupps
Why is my Caterpiller 3406 diesel engine running rough when cold with misfire and has excessive white smoke?
i have a 3406b inframed new head injectors runs rough and pours white smoke had pump and timeing advance off timeing advance rebuilt put back on. now its worse
On a 2004 F-250 Power Stroke 6.0 diesel why does is shoot out black smoke first thing in the A.M. from the exhaust pipe and runs rough and smooths out about half hour after running engin?
Seeing as it is a diesel engine it has to warm up first in the colder weather. You say that you are starting the engine early in the morning? Well the black smoke may be caused by he motor being cold or simply by the fact that it is a big diesel engine. The rough ride you are referring to is caused by the motor being under-heated, and then as the engine heats up it smooths out.
Mercedes sprinter diesel engine hard to start when cold?
Most diesel engines are hard to start when it is cold. Plugging the diesel engine block heater in will help the engine start.
You had your 94 4runner engine rebuilt 15000 miles ago It started running rough when cold now it is running rough all the time even at idle and began backfiring at little any troubleshooting ideas?
check your ignition timing.
Does cold diesel make your car go better?
No, never put diesel in a gasoline engine it will foul up the sparkplugs in your engine, clog it up, and make it smoke alot. Cold Diesel in a diesel engine isn't too good either because when diesel gets cold it gels up, that is why most diesel engines have a built in heater to warm up the engine and fuel before starting. Hope this helps
2001 dodge 2500 cummins will not go when it is cold?
How cold is it. Most diesel engine do not responed properly when the engine and fuel is cold.
What causes your 1996 power stroke diesel to idle rough at times but not all of the time?
This depends on the temperature outside and if your starting it cold. If you start it cold even in 60 degree weather it may idle rough for the first few minutes. You can solve this by letting the Wait to Start light to go out and then pressing the Throttle down slightly and letting off. This engages the high idle which should stop your vehicle from running rough for so long, as it lets the engine warm up faster.
Diesel engine runs cold does it use more fuel?
It can and probably will
What will cause a diesel engine to smoke?
when it get really humid or very cold
What does a Glow Plug Do crde engine?
A "glow plug" preheats the cylinder. Diesel engines do not have spark plugs (Diesel's goal was to make an internal combustion engine that could run on anything; he specifically had in mind a kind of slurry made from coal), instead using the heat of compression to ignite the fuel. This usually works fine when the engine is actually running, but it can be difficult to cold start a Diesel engine since the cylinder and block absorb some/most of the compression heat (it's not a problem once the engine's been running, because by then they're already hot). The glow plug exists to preheat the ignition chamber and/or the fuel, making it easier to start the engine from a cold state.
