Why petrol cannot be used in diesel engines and vice versa?
Diesel fuel is used in diesel engines as a partial lubricant. It also has a high flash point due the fact that diesel engines ignite the fuel by compression rather than spark. A gasoline engine on the other hand fires the fuel by spark and the fuel has a lower flash point. Gasoline has no lubricating qualities whatsoever. Diesel engines are designed to run on diesel fuel and the use of gasoline in a diesel engine will destroy it. Gasoline engines on the other hand will not even run on diesel but no damage will be done to the engine. You will however have to drain the fuel tank and flush out the fuel lines.
What is diesel fuel?
Diesel fuel is the kind of fuel used by diesel engines. Its a combustible fuel refined from crude oil - just as is gasoline - but diesel has a much higher flash point than gasoline. Its grade is measured in cetane rather than octane
What are the defferences between dessel and petrol engine?
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
Why does a diesel engine use a different type of fuel?
Diesel engines do not require "ignition" to burn diesel fuel--it is powered by the "heat of compression" therefore diesel fuel has a much higher "flash point" than gasoline. If you were to put gasoline in a diesel engine you would probably blow the heads off the engine. Due to lower "flash point" (temperature when fuel ignites). If you were to put diesel fuel in a gasoline powered engine, it would not ignite and engine will not start. Due to higher "flash point).
Why is High flash high speed diesel used in ships instead of high speed diesel?
HSD is having a flash point about 32 deg C and HFHSD flash point is above 66 deg C. Ships' engines are designed with low RPM where as road running vehicles engines are designed to above 750 RPM During compression ,fuel get heated and it can be under risk of Fire due to low flash point of HSD. To avoid or minimize fire risk HFHSD(flash point above66) is used in ships
What is fuel oil?
A liquid petroleum product having a flash point above 37.8°C, used for heating in furnaces and engines. Normally kerosene and diesel, not gasoline.
How do you increase the flash point in diesel oil?
A low flash point in diesel is caused by contamination of the diesel with lighter petroleum products such as kerosene or gasoline. Drawing more lighter products out of the fractionation tower could reduce contamination of the heavier products. Improving fractionation and improving diesel product stripping performance will raise the flash point.
Why the cars which run on petrol cant be run with diesel?
Petrol engines use a spark plug to ignite the gasoline. Diesels on the other hand use compression to ignite the fuel. Diesel engines have a very high compression ratio that causes the fuel to ignite under pressure. Gasoline engine do not run near the compression as a diesel. Put diesel in a gasoline engine and it simply will not run. Reason being is that diesel fuel has a much higher flash point. Gasoline contains 4 to 12 carbon atoms, diesel has 10 to 20 carbon atoms and is much heavier than gasoline.
What burns hotter gas or diesel?
Petrol first. it has a lower flash point than diesel.
Why would diesel not light?
Diesel does "light" as do most flammable liquids. I am assuming that you mean why would diesel not light if I put a match/cigarette to it then the answer is as follows : Diesel is made up of "heavy" molecules made up of hydrogen and carbon. This means that it requires a lot of energy e.g. a high temperature to make them turn into a gas so that they will burn. The minimum temperature required for Diesel to ignite when a flame is applied (technical term is the flash point) for Diesel is above 62 degrees C hence even on a really hot day the diesel won't be hot enough to ignite. (The hottest day ever recorded was 59.8 degrees C in death valley US) In comparison the flash point of petrol (gasoline) is around -40 degrees C hence why it will quite happily ignite when a flame or spark is applied. This is why petrol engines use spark plugs but diesel engines don't.
What temp does diesel burn?
D2 Diesel flash point, 126 degrees F.D2 Diesel autoignition temp, 493 degrees F.
Can you use diesel in a zippo?
No, you can't. Diesel has much too high a flash point and won't ignite in a Zippo.
