2. A four-cylinder 2.5 L spark-ignited engine is mounted on a dyno and operated at a speed
of W=3000 rpm. The engine has a compression ratio of 10:1 and mass air--fuel ratio of
15:1. The inlet air manifold conditions are 80 kPa and 313 K. The engine produces a torque
of 160 Nm and has a volumetric efficiency of 0.82.

A four-stroke (i = 0.5 for fourstroke engine, stroke = 150 mm and revolution = 2100 min−1) diesel engine with 6 cylinders and an effective specific fuel consumption of 0.23 kg kW−1h−1 has an effective and indicated mean pressure of 9.2 bar and 6.8 bar, respectively, and a compression ratio of 17. The ambient temperature and pressure of the diesel engine is 30 ℃ and 1.017 bar, respectively, and the temperature of the exhaust gas is 650 ℃. The clearance…arrow_forward5. A Wankel engine (Figure 12-16) uses triangular rotors in a specially shaped combustion chamber to replace the traditional piston and cylinder. As the rotor turns, each of its three sides goes through a four-step cycle. During the intake stroke, fresh air is mixed with fuel as it is drawn into the engine. The rotor then seals off the fuel-air mixture and com- Figure 12-16 Problem 12-5 Intake Compression Power Exhaust mences to com- press it. In the power stroke, the spark plug ignites the mixture. The burning gases expand, adding momentum to the rotor. As the rotor completes its cycle, the burned gases leave the engine through the ex- haust port, and the cycle begins over again. From the above description of a Wankel engine, identify the four thermodynamic processes that drive this device. Can you identify the cycle (Otto, Diesel, Carnot, and so on)?arrow_forward
