Calculate the thermal efficiency and compression ratio of a petrol engine, if the suction temperature was 375 K and the temperature at the end of the compression was 577 K (y = 1.41)

Explanation

To solve the problem of calculating the thermal efficiency and compression ratio of a petrol engine, we will follow these steps:

### Step 1: Calculate Thermal Efficiency

The thermal efficiency (\( \eta \)) of an Otto cycle engine is given by the formula:

\[
\eta = 1 - \frac{T_1}{T_2}
