WHY THE WANKEL?
To further our modeling skills Obtain a better understanding of the workings of the rotary
engine and the thermodynamic cycles that go on within Transmission was also a challenging piece of machinery Good example of thinking outside the box To inform people that there are alternatives to the conventional
four stroke cylinder engine

HISTORY Designed by German engineer Felix Wankel in 1954 Manufactured mainly by Mazda, currently used in Mazda RX-8 Extremely lightweight and small when compared to engines with
similar power output Used in a lot of aircraft Main disadvantage is fuel inefficiency

Uses pistons to regulate intake and exhaust of fuel and gas.
All four strokes, intake compression, combustion and exhaust occur in same cylinder.
Pistons continually reverse direction creating more wear and tear on the engine
Bad power to weight ratio in comparison
Lower rev limit
Has a spinning rotor that creates three separate chambers and regulates the inflow and outflow of gasses.
Each chamber draws in air and fuel, is compressed, ignited and combusted then expelled creating power while at the same time forcing the other two chambers to do the same.
Rotors move in a continuous direction making it smoother
Only about three moving parts creating less friction and less possibility for error

CHALLENGES & DIFFICULTIES Transmission
• Many moving parts• Gear ratios were very difficult to get right• Constraints started conflicting
Engine• Measurements for rotor pieces and rotor housing were difficult to obtain• Some pieces needed to be generated by equations• Interference between housing and rotor was an issue• Inserting gear constraints between all moving parts was difficult to get right
Assembly• Pieces needed to be continually adjusted to fit together properly

SUMMARY The Wankel Rotary engine is still a promising piece of
technology Mazda continues to spend money on the concept with
the hope of improving its fuel efficiency There are also several other types of rotary engines
that run on various types of fuel We utilized and furthered all the skills taught to us in
ProE class including assembly, constraints, sweeps, blends, gear connections, animations
