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.).

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
