HE: Diesel Cycle

Question 1

Diesel Cycle: Equation for q(in) & q(out)

Answer 1

q(in) = h3 - h2 // m*c (T3 - T2)

q(out) = u4 - u1 // m*c (T4 -T1)

Question 2

Diesel Cycle: Compression Ratio

Answer 2

r = v1 / v2

Question 3

Diesel Cycle: Compression Ratio Equation

Answer 3

r(c) = v3 / v2

Question 4

Draw p-v & t-s diagrams for Diesel Cycle.

Question 5

4 stages of Diesel Cycle.

Answer 5

1-2: isentropic compression
2-3: constant pressure heat addition
3-4: isentropic expansion
4-1: constant volume heat rejection
