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.
Can Diesel Fuel ignite from a flame?
Yes but only in the right conditions. If diesel is outside just on the road, for example, then no it will not ignite from a flame.
Can number 4 fuel oil be used in a diesel engine?
No #4 diesel fuel oil is for oil burners and will not ignite in a diesel egine
Which engine type relies on heat compression to ignite the fuel?
Diesel engines rely on heat and high compression to ignite fuel.
Where does the word diesel come from?
'Diesel' comes the German engineer, Rudoplf Diesel. Diesel invented an internal combustion engine that would auto ignite, when the fuel vapours were compressed to a high degree. This increased the temperature of the vapour to the point were it would auto ignite. The fuel that he used was slightly different from petrol, which needed an electrical spark to ignite. This slightly different fuel is now known as 'Diesel'.
Why you can't use diesel in petrol vehicle?
The fuel will not ignite properly.
Why twin spark is used only in petrol engine?
Diesel engines do not use spark plugs to ignite the fuel. Instead they use the actual compression of the piston to ignite the fuel. To start a diesel engine a glow-plug is used, once the engine has started the compression causes the ignition. As a results of this diesel engine blocks are heavier to take the force of the ignition
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 is the minimum temperature in a diesel engine cylinder for the fuel to ignite?
35 c
Do diesel engines require spark plugs?
No diesel engines use the "heat of compression" to cause fuel to ignite not electrical ignition.
Can a diesel engine catch on fire if its leaking fuel?
Yes it can if the fuel gets hot enough to ignite as in leaking on a header.
Why does diesel do not have electric ignition system?
because of in the diesel engine fuel injector is uses for ignite the charge & they are operated by fuel pump not to electricity and in the diesel engine there is no requirement of spark plug to genrate the spark
