Question:
A four-stroke gasoline 4.2-L engine running at 2000 RPM has an inlet state of 85 kPa, 280 K. After combustion it is 2000 K, and the highest pressure is 5 MPa. Find the compression ratio, the cycle efficiency, and the exhaust temperature.
Fantastic news! We've Found the answer you've been seeking!
Step by Step Answer:
To find the compression ratio we need to find the volume of the gas at the end of the compression stroke and the volume of the gas at the beginning of the compression stroke The volume at the beginnin...View the full answer
