An ideal Otto cycle engine, an ideal Diesel cycle engine, and a Stirling engine all have a maximum volume of 1 liter. The volume at the end of combustion for the Otto and Diesel engines is 0.1 liter. The minimum volume for the Stirling engine is 0.1 liter. All three engines operate with air initially at 100 kPa, and have a minimum temperature of 300 K and a maximum temperature of 1200 K. Determine how much work is done for each cycle of the three engines and compare the thermal efficiency for each engine. Use a variable specific heat analysis using table A-17.

Really appreciate any help and especially any explanation... This class has killed me. :/
