Question: 2 30 points find the engine volume and compression ratio...

Question details

2. (30 points) Find the engine volume and compression ratio from the paper. Use those numbers to calculate the following and list any assumptions you make about the cycle in your document. Assume that air has γ-1.4 and R-287 J/kgK. and the engine is running an air-standard ideal Otto cycle. Indicated work produced each cycle (in Joules) Heat addition each cycle (in Joules) - assume the engine runs off gasoline with a lower heating value of 42 MJ/kg and air-to-fuel ratio of 14.7 (stoichiometric for gasoline). The lower heating value is the amount of heat generated from the combustion of a liquid fuel per unit mass. Indicated thermal efficiency of the engine. a. b. c.
