Winter deisel in summer

[Jocky]

Jocky from what I've read on the net, it seems that Kero has a lower burn temperature (does that equal lower calorific value?) so wouldn't produce quite as much energy as straight diesel??

I don't know about burn temps etc, but I'll give you an example or running jet engines

Right where I work now we've got 3 rolls royce RB 211 Turbines (jet engines) they are normally run on Fuel Gas straight out the North Sea, the calorific value of that changes, due to gas composition.
When that supply is lost for any reason they swap staight over to diesel, (red diesel) they run exactly the same and exhaust gas temps etc are exactly the same as on gas.



Zippy, before all this winter, summer diesel stuff started, wagon drivers used to put petrol into the tank in winter to stop it freezing. Only thing we need to worry about is the CETANE number of the DERV.
