Afour cylinder, four-stroke spark ignition engine with a total displacement of 2.4 l runs at 2500 rpm. the processes within each cylinder are modeled as an air-standard otto cycle. at the beginning of the compression process (state 1), the air is at 85 kpa, 290 k. the compression ratio is 9 and the maximum temperature in the cycle is 2000 k. determine:
a. net work output per cylinder (per cycle) kj]
b. energy added by the combustion process per cylinder [kj]
c. thermal efficiency
d. mean effective pressure
e. power output of engine [kw, horsepower
