Answer:

The theoretical efficiency of the Otto engine is 59.4 percent.

Step-by-step explanation:

The theoretical efficiency for Otto engine (
$\eta$ ), dimensionless, is obtained by this formula after supossing that fluid is an ideal gas:

$\eta = 1-(1)/(r^(\gamma -1))$

Where:

- Compression ratio, dimensionless.

$\gamma$ - Heat capacity ratio, dimensionless.

Given that
r = 9.50 and
$\gamma = 1.40$ , the theoretical efficiency of the Otto engine is:

$\eta = 1 - (1)/(9.50^(1.40-1))$

$\eta = 0.594$

The theoretical efficiency of the Otto engine is 59.4 percent.
