What lights the fuel in a diesel engine?
Diesel fuel is ignited by a combination of heat and compression. The heat is caused by the very high compression in the cylinder. The fuel also has to be very finely atomised to be able to burn.
What is the heat of combustion of diesel fuel?
Diesel heat of combustion : 45 MJ/kg , 10.7 Mcal/kg 19,300 BTU/lb
Which engine type relies on heat compression to ignite the fuel?
Diesel engines rely on heat and high compression to ignite fuel.
Can you use the oil from your truck too heat your home?
If you are talking about standard #2 diesel fuel oil and not motor oil and you have a #2 oil fired furnace or boiler in the home the answer is yes .
Why does your diesel truck have two batteries?
Vehicles with diesel engines require more cranking power to get the engine started. This is because diesel engines have much higher compression in the cylinders than gasoline engines. A diesel engine uses the heat from compression to ignite the fuel. So, it takes more energy to rotate the starter fast enough to create enough heat and compression to start firing. In colder weather two batteries are a must have for a diesel as the fuel becomes thicker in colder temperatures and is harder to ignite
Can I use diesel fuel to heat my house instead of 2 fuel oil?
u can use diesel fuel but why would you? heating oil has no tax and is so much cheaper than road fuel
Can a match stick burn diesel fuel?
Diesel fuel is ignited by heat AND compression. For example: Throwing a lit match in a bucket of diesel fuel won't ignite it. However, Gasoline will catch fire with just heat. PS, Don't try that trick I taught you in sentence 2! Be smart and safe!
What is the difference between diesel fuel and diesel?
Diesel is a type of internal combustion engine wherein the fuel is ignited solely by heat produced by rapid compression of the air in the cylinder. Not by an electrical spark as in a gasoline engine. As the cyl air is compressed the air becomes heated. Fuel is injected into the hot cylinder and is ignited by the heat alone
Do diesel engines require spark plugs?
No diesel engines use the "heat of compression" to cause fuel to ignite not electrical ignition.
How fuel is ignited in diesel engine?
Just due to the heat of Compression. The fuel is Injected at a point where the air temp is high enough the fuel burns.
What do glow plugs do in a diesel engine?
They preheat the air in the cylinder to make starting easier. they actually heat the diesel fuel to make starting easier
How does diesel fuel ignite in the engine?
The engine's pistons compress the fuel (an air and diesel oil mixture) in the cylinders and the heat generated by that compression causes the fuel to ignite.A longer answerDiesel engines ignite their fuel solely by means of compression: whilst spark plugs are used to ignite the gasoline fuel and air mixture in gasoline engines, in diesel engines the diesel oil and air mixture is compressed to a very much higher degree, which causes a lot of heat. The resulting very high temperature causes the fuel to self-ignite.
