- Draw the p-V diagram and typical valve timing diagram for a two stroke IC engine.Describe a 4-stroke compression ignition engine operation with neat sketches.I am having a hard time understanding C-E on this problem. For C, I know that Th>Ti>Tc. Does that mean that since ec= 1-Tc/Th and Tc is the lowest temp of the system, that it is indeed more efficient with both engines? The other ones, I just don't know where to start. Any help or explantions would be appreciated!
