8. Draw the graphic symbol for a two-position spring centered valve, a spring offset
valve, an energize-to-center valve.
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-

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)?
