Estimate the maximum efficiency of an automobile engine that has a compression ratio of 5:1.0. Assume the engine operates according to the Otto cycle and assume γ = 1.4.

Respuesta :

Answer:

Efficiency of an Otto cycle is = 47.47 %

Explanation:

Compression ratio (r) = 5

Ratio of specific heat ([tex]\gamma[/tex]) = 1.4

Efficiency of an Otto cycle is given by  = 1 - [tex]\frac{1}{r^{\gamma - 1} }[/tex]

Put the values of r and [tex]\gamma[/tex] in above formula we get

Efficiency = 1 -[tex]\frac{1}{5^{1.4 - 1} }[/tex]

Efficiency = 0.4747 = 47.47 %

This is the efficiency of an Otto cycle.
