Diesel engines use heat and compression to ignite fuel. Although not needed in more modern diesel's many had glow plugs in a similar placement that is used to add the required heat for starting, but are not needed once at temperature. With higher injection pressures allowing a finer mist of fuel, thus requiring less heat and compression, glow plugs have largely been eliminated (but still have other heaters for cold weather starts.)

Do diesel engines require spark plugs?
No diesel engines use the "heat of compression" to cause fuel to ignite not electrical ignition.
What is the glow plugs for?
Glow plugs provide the heat for combustion in diesel engines, just like spark plugs are used to ignite regular gasoline in standard engines.
Why do you need to bleed a diesel?
Diesel engines work in a different way to petrol in that they work on pressure to ignite warm diesel as opposed to petrol engines which have spark plugs. in order to work, there can be no air, air wont ignite!!
How many spark plugs in a 7.3L v8 diesel engine?
Today's diesel engines do not use spark plugs.Today's diesel engines do not use spark plugs.
Why don't diesel engines use spark plugs?
diesel engines do not use spark plugs because diesel has more oil, burns slower, and is more difficult to ignite. Therefor spark plugs are insufficient with just spark so instead they use glow plugs witch provides a high amount of heat to the fuel and ignites more quickly and reliably.The amount of compression pressure in a diesel engine is sufficient to produce enough heat to ignite the fuel. The glow plugs are only used on a cold start.
Why do diesel engines ignite even though they have no spark plugs to ignite this mixture?
Compression and heat. The fuel/air mixture is compressed to such a high level as to get hot enough to cause the mixture to self ignite. Gas engines require a spark to ignite the fuel. Gasoline engines have a compression ratio of 8:1 to 12:1. Diesel engines have a compression ratio of 14:1 to 25:1.
Do diesel engines have spark plugs?
no
Are there spark plugs in turbofan engines?
No. There are not "spark plugs" on turbofan engines. There are ignitors, which help to ignite the fuel during start, but unlike spark plugs, ignitors do not run constantly.
What engines do not use spark plugs?
Diesel
Spark plugs cause the ignition in Diesel engines?
No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition
Why can't spark plugs be used in diesel engines?
Diesel does not require a spark to combust.
Where is the spark plugs located on a 2004 Dodge Ram 2500 Turbo Diesel?
The main reason of not using the spark plugs in diesel engines is because of the diesel having a low ignition temperature. At the end of the compression stroke the pressure and temperature values achieved are sufficient to ignite the diesel which is sprayed into the hot air in the combustion chamber.
