PLEASE SOLVE AS MUCH QUESTIONS AS YOU CAN
1. State the different types of scavenging methods used
in two stroke cycle engines and mention which one the most
efficient in emptying the cylinder from exhaust gasses and filling
it with fresh mixture.
2. Define the trapping efficiency, scavenging
efficiency, and delivery (scavenge) ratio and find a relation
between them
3. Explain the benefit of supercharging the internal
combustion engine, explain also the difference between the
turbo-charging, mechanical supercharging, manifold
tuning.
4. Define the flame in petrol and diesel engines, i.e.
whether it is laminar or turbulent, steady or unsteady, pre-mixed
or diffusion
5. How can you reduce the combustion time losses in
S.I. Engine
6. Describe briefly the combustion process in
stratified charge engine
