(5): The advantage of the optimized size of the piston is that it requires less material so the cost of the material of the engine is reduced and space is also increased by reducing the size of the skirt.

Question 3 (i) What information is needed to make an accurate estimate of the annual energy capture for a wind turbine? List at least two control mechanisms available in modern wind turbines, which respond to variations of wind speed and direction?
5. 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)?
