1)Calculate the Otto cycle efficiency of an engine with a maximum combustion temperature of
1400ºC, a peak temperature after compression of 325ºC, an exhaust gas temperature of 450ºC,
when operated with an underhood temperature of 70ºC.Then, estimate the actual efficiency of
the engine.
2) What is the auto-ignition temperature of gasoline? Would a brand-new engine that is
overheating be more likely to detonate or experience pre-ignition in light of this autoignition
temperature? Why?
3) Why do you need high volatility fuel in the winter season?
4) What is a typical 10% vapor/liquid ratio temperature for gasoline?
5)In a four stroke engine, what is the ratio of cam to crank shaft revolutions? What are some benefits of a hemispherical head shape?
6) At what rpm is a four stroke, three cylinder motorcycle engine running if any given spark plug is
firing every 10 milliseconds?
