Part 2
A compression ignition engine operates on a diesel cycle has a compression ratio of 20 and uses air
as the working fluid, the cut off ratio is 1.5. The air at the beginning of the compression process is
at 100 kPa and 30 C. If the maximum temperature of the cycle is 2000 °C. Under cold air standard
assumptions at room temperature.
a. Describe with the aid of diagrams the operational sequence of four stroke compression
ignition engines.
b. Explain the mechanical efficiency for an ideal diesel cycle of two and four stroke engines
c. Explain the relationship between thermal efficiency (n), compression ratio (r), and cut-off
ratio (r.).
d. Determine the net-work output, the thermal efficiency, and the mean effective pressure for
the cycle.
