Answer


Step 1​

For a perfect heat engine, the ratio 515960-15-18PE-i1.pngequals the ratio of the absolute temperatures of the heat reservoirs. For a Carnot engine,​

515960-15-18PE-i2.png

Step 2​

Here 515960-15-18PE-i3.pngis the heat taken from the system, 515960-15-18PE-i4.pngis the heat put into the system, 515960-15-18PE-i5.png is the temperature of the cold reservoir and 515960-15-18PE-i6.pngis the temperature of the hot reservoir.
,

Step 3​

So if 515960-15-18PE-i12.png and 515960-15-18PE-i13.png are given, we can calculate the maximum efficiency using the formula515960-15-18PE-i14.png. Modern gasoline engines have a maximum thermal efficiency of about 25% to 30% when used to power a car.
