An automobile uses a four-cylinder engine. Within each cylinder of the engine, the processes can be modeled as an air-standard Otto cycle. At the beginning of the compression process, the cylinder volume is .559 L. The temperature and pressure are 330K and 1.5 bar, respectively. In the cycle, the maximum temperature is 2200K when the engine operates at 3000 RPM. If the engine compression ratio is 9.5, determine

(a)  the air mass flow rate to the engine in g/s.

(b) the heat addition to the engine in kW.

(c) the net work of the engine in kW.

(d) the thermal efficiency of the engine in %.

(e) the mean effective pressure of the engine in bar.
