Yes, diesel fuel can be ignited, but it requires a higher temperature compared to gasoline due to its higher flash point. While it won't easily ignite from a spark or open flame, it can catch fire if exposed to a sufficiently hot surface or flame. Once ignited, diesel burns steadily and can produce a significant amount of heat and smoke. Always exercise caution when handling any flammable liquids.
It will not run with diesel.
68 degree Celsius
As low as 126 degrees Fahrenheit, diesel fuel could potentially catch on fire. This is known as the temperature of ignition.
According to my manual, the fuel light goes on when the tank is down to approx 6 litres of diesel.
The critical temperature of diesel fuel is typically around 400-450 degrees Celsius. Above this temperature, diesel fuel can vaporize and pose a serious fire hazard. It is important to handle and store diesel fuel carefully to prevent accidents.
Probably not but why is it in there and how much?
No, diesel fuel is not easy to set on fire. It has to have a good wick, or be vaporized to be quickly set on fire. You can put out a match in a pool of diesel fuel, but you wouldn't want to drop a match into a tank that holds it, as enough may have evaporated to cause it to ignite. It is not as volitile as gasoline.
Yes you can mix oil and diesel for burning brush and stuff just don't put it in any engines!
Diesel fuel is not very volatile. It's very unlikely (I hesitate to categorically state "impossible") that it could be ignited by a cigarette.
Yes it can if the fuel gets hot enough to ignite as in leaking on a header.
The sparks plugs fire and ignite the fuel in a Gasoline engine, and compression compresses the fuel until it ignites in a Diesel engine.
My Mk3 fiesta did not.
