Fast practice, instant feedback. Timer auto-submits when time’s up.
Avg score: 68% • Most missed: “Fuel air ratio affects maximum power output of the engine due to ____________”
Fuel Air and Actual Cycles and their Analysis topics include: Fuel air cycle, dissociation, actual cycle, air cycle and fuel cycles, effect of operating variables. A fuel-air cycle analysis considers the effects of variations in fuel-air ratio, inlet pressure and temperature on engine performance. The fuel-air cycle is a theoretical cycle that considers the actual properties of the cylinder contents. The analysis makes the following assumptions: There are no chemical changes in either fuel or air before combustion After combustion, the charge is always in chemical equilibrium All... Show more
