can petrol or any other fuel be fed into diesel engine or vice-versa? please explain in details. what are the parameters to be considered for change of fuel?
Vishal,
Briefly, "yes" - you can put in any other fuel. But don't expect the engine to work.
(sugar is a fuel - adding it to a gasoline tank will win you no friends)
Diesel engines require that the fuel/air mixture ignites purely from compression - hence the high compression ratio and the absence of spark plugs.
I am puzzled that an assistant professor in a department of engineering would not know the basics of internal combustion.
Dear Vishal,
Yes you can do it.
but you need to adjust your compression ratio (usually very high for petrol as compared to diesel) according to the self ignition temperature of the fuel. But it may knock....
A friend of mine said, you can eat all mushrooms, but some of them only once...;o)
Joke aside, in war people in Bosnia used transformator oil in diesel engines. For internal combustion one needs fuel in vapor, oxygen and outside heat source and no matter what the fuel is it will be plausible. There are engines in military vehicles (tanks for example) that have taken this into consideration...
Absolutely not. Because the fuel with high calorific value (petrol) easily burns when compression cycle starts and which is not preferable. Compression ratios are also different. Construction details are also different. The other fuels like pongamia, jatropa, neem, etc can be used, as it is having near to the calorific values of diesel. The other properties like viscosity, ignition point, etc..of fuels which are near to the values of diesel can be used easily.
