A four-stroke cycle engine may or may not have a pressure boost (supercharger, tur- bocharger) in the intake system. Why must a two-stroke cycle engine always have an in- take pressure boost?

Describe how actual internal combustion engine cycle(i.e. Otto and Diesel)thermal efficiency differ from the ideal one at the same power output.

Q1/ Answer the following questions: 1. We can classify I.C. engines to give a clear description for any engine? Give your opinion about that. 2. Side thrust force may give an indication about the engine performance. Discuss that. 3. It is possible to increase the mechanical efficiency of the turbocharger. Do you agree? Why? 4. How is the friction force reduced? 5. If the engine designers reduce the piston skirt length as much as possible, is this considered as an advantage for the I.C. engine?

1.Why have eight cylinders in an engine? why not have one big cylinder of the same displacement of the eight cylinders instead? 27. What causes white smoke in two stroke locomotive engines? 28. Why efficiency of gas turbines is lower compared to internal combustion engines?
