Homework Statement
A diesel engine requires no spark plug. The air in a cylinder is compressed so
highly that the fuel spontaneously ignites when sprayed into cylinder. If the air is
initially at 20°C and is then compressed by a factor of 15 in volume, what final
temperature is attained (before fuel injection)? Assume the compression is adiabatic,
and treat the air as an ideal gas. Take delta = 1.4 for air. By what factor does the
pressure increase?
Homework Equations
PV^ delta = constant
TV ^delta-1 = constant.
Delta = Cp/Cv.
Internal energy = Work done.
The Attempt at a Solution
I am totally lost with this problem, I know what an adiabatic process is, how to derive the delta, etc but I can't seem to match that with the above question.
Any tips ?
