Comments by "TheThirdMan" (@thethirdman225) on "4 Reasons Why The Rotary Engine Is Dead" video.

  1. There is actually another video about the advantages of the rotary engine, should anyone want to watch it. The biggest problem for the rotary is simply emissions. People still buy plenty of thirsty V* (trucks) and don't complain so in performance terms, I don't think economy is that much of an issue. Passing emissions requirements is.

  2. Robert McDonald Well, I don't know anything about cars but I respect alternatives to any dominant paradigm. The fact that the rotary engine even made it into production, in the face of the dominance of reciprocating engines, is important for its own sake. The bottom line is this: each engine is a mechanical solution to extracting the maximum amount of energy from every drop of fuel. Some win on power out put. Some win on economy. Some win on weight. Some win on flexibility. There is no one perfect solution.

  3. The real doktorbimmer "What advantages?" I don't know. I made it lear that I don't know very much about engines. What are you trying to prove from what I said? One thing might have been worth looking at. In the Mazda 787B, the small size of the engine almost certainly made the centre of gravity very low. I would have thought that balancing out a rotary engine would be relatively easy too.

  4. The real doktorbimmer Are you looking for an argument? I told you; I'm not an expert in engines.

  5. The real doktorbimmer I'm not confused about anything. Reread my original post.

  6. The real doktorbimmer That was from a purely legal point of view. Mazda could not meet newer emissions standards. Now, I have better things to do with my time, so I suggest you find someone else to lecture on things I don't care about.

  7. James Cagney No way. Gas turbines are much more efficient.

  8. Daniel Brealey I see your point but all engines have their best operating levels. The fact that a rotary engine doesn't reciprocate like "traditional" car engines do means that rev limitations are not quite so binding. Some jet engines, such as APU's, frequently rev to 50-60,000 because they use constant combustion but they can't function efficiently - if at all - at 10,000. I don't see that as a problem. Certainly the other point you raise about oil is true. What was the most likely component to fail in a rotary race engine? (Genuine question: I don't know the answer to this) "hp can be assessed as torque multiplied by rpm" Don't forget to divide by 5252. ;)

  9. How many HP per litre of capacity compared to a reciprocating engine? What is the weight of the engine for its output? What was the most likely component to fail?
