As part of an engineering course, I have been presented with a list of topics to research. It seems that my next few tutorial sessions will deal with internal combustion engines quite deeply. This is a bit of a culture shock to me.
The list is presented as a series of questions. I've managed to find information on most of them, but one has totally stumped me.
"A four-stroke motorcycle engine has been restricted by having its exhaust pipe partially blocked close to the outlet from the engine. In general terms, how would you expect the torque-speed relationship of this engine to differ from that of an unmodified engine, and from that of an equivalent two-stroke engine?"
Can anyone please help me with this?
Thanks in anticipation.
