Has anyone looked into the economics of rotary engines?

Question

I hear rotary engines have only 3 moving parts and are 25% lighter and can run on multiple fuels.

Answer 1

The Wenkel Rotary worked and works fine. So do many other types of this motor:See Mazada Race Trophy cases.
It is not economically viable to the manufacturer to make a thing that works. This is Anti Capatlism, and somewhere along the way, we became Capatilists First, freedom,truth,helping the humans are like 23rd or more.
Rotary is the also one of the most pursued concepts in any near perpetual motion design. But if the designer gets close, it is either bought and then destroyed by the Goverment, for our good, or some Corporation, for party streams at the Stockholders meeting.
There is a flaw in the design, it is the Human element, or H^1. If we have a horse, we will have a horse race, if we have motor that works, we will fight a war with it. This is human nature. We are the problem in this matter. So yes I have studied some on the Rotary Engine, and yes I have seen the economical nightmare it is for the current Corporate World Goverment.

Answer 2

Oh sure, Mazda nearly converted 100% of its passenger cars and small pickups to Wankel rotarys in the 70s. The only ones now I'm aware of are in their hot RX8. Emissions are hard to control in a rotary, heat is a problem at the high RPM, and low-end torque is lacking compared to 4-stroke piston engines. Low end torque is 90% of your daily driving, so a Rotary feels more like an on/off switch than a smooth powerplant in traffic. Enough people voted with their money that Mazda went back to piston engines.

They rev to the moon, however, and are great fun to drive in a race car where you keep the RPMs up. The Twin Turbo RX7 my roommate had in college never stopped pulling when you had your foot in it, but was miserable to try to drive in stop-and-go traffic.

Any internal combustion engine can be tuned to run on multiple fuels so that's not unique to the Rotary.

Answer 3

it does create gyros whih could be a problem.. but the hard part is getting the money the support it. i doubt the auto and oil industrys wouldnt try and squash it as it would decrease there profits by alot
