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?
