In a spark ignition engine working on the ideal Otto cycle, the compression ratio is 5.5. The work output per cycle (i.e., area of the P – V diagram) is equal to 23.625 × 105 × VcJ, where Vc is the clearance volume in m3. The indicated mean effective pressure is

- 4.295 bar
- 5.250 bar
- 86.870 bar
- 106.300 bar
- 4.295 bar
Correct Option: B
| = 5.5 | ||
| Vc |
V1 = 5.5 Vc
Vs = V1 – Vc
Vs = 4.5 Vc
work output = 23.625 × 105 × Vc Joules
