Question

A 4 cylinder, 4 liter compcompression-ignition engine operates on the air standard dual cycle. It uses light duel fuel at air fluid ratio of 18. The compression ratio of the engine is 16:1 and cylinder bore diameter is 10cm. At the start of the compression state, conditions in the cylinders are 60°C and 100kPa with a 2% exhaust residual. It can be assumed that half of the heat input from combustion is added at constant volume and half at constant pressure.

Calculate:

1. Temperature and pressure at each state of the cycle.

2. Indicated thermal efficiency

3. Exhaust temperature

4. Air temperature in intake manifold

5. Engine volumetric deficiency
