1. The problem statement, all variables and given/known data
given:
diesel cycle,
P1V1 P2V2 P3V3 P4V4 - all known
T1 = 20c
specific heat capacity constant pressure = 1000j/kgk
specific gas constant = 287j/kgk
compression index = 1.4

2. Relevant equations
heres where i am stuck!


3. The attempt at a solution
Hi all, im unsure where to go with this one. im guessing that i need to work out T2.T3.T4, but cant find in any of my notes where any of the γ or R come into play or how to get T2T3T4?. i have already calculated the work done for each stage in a previous part of the question so i have that. Just not too sure on where to go from here to calculate the efficiency of the cycle?
