  1.  @KontrolCZ  ?? Not sure why you think I'm not letting people enjoy something, I had an RX-7 Turbo II for well over 10 years, modified it and drove it to work everyday. Pretty good little engine, fuel consumption was high though.

  2. Wankel engines still have pistons--the rotors themselves. A Wankel is a type of piston engine, it works using displacement. The motion is different, the function is the same. The original term for Wankel rotary engines was "rotating piston machine."

  4.  @a-cast3496  Wankel engine pistons (rotors) are cast iron, at least for Mazda engines... Aluminum ones probably weren't strong enough to put up with the very high rotating mass. Either that or the seal slots would wear out when they made them out of aluminum.

  5. If an old car still runs and drives well, it's not because the older cars were better. It's because somebody put a huge amount of work into maintaining it!

  6.  @rogueart7706  You've driven it every day for 42 years, many hundreds of thousands of miles (millions), and never done anything but basic maintenance like oil changes and spark plugs? Come on man, really? Oh yeah, every truck is made of steel. There has never been a plastic-bodied truck, only a rare few cars. There's nothing wrong with plastic body parts on vehicles, they are not mechanical and have nothing to do with the vehicle's reliability.

  8.  @jinxtacy  That's right--those old aircraft engines were "rotary" by definition because the entire crankcase rotated, with the crankshaft stationary. It made for better fuel-air mixture distribution among the cylinders, instead of the lower cylinders running too rich and the upper ones running too lean. It also meant that they were unwieldy, clunky things that could only be run at very low RPM, so the power output was dismal for the engine's size and weight. Rotating-crankcase engines were only around for a little while before improved designs, called "radial" engines, with a stationary crankcase and rotating crankshaft were developed.

  9. Huh? There are probably more people in the world who are engineers today than ever before!

  10.  @dynamitelawyer6549  Well, the idea is that they shouldn't break :)

  11.  @trappster48  Doesn't make much difference, the rest of the engine is usually knackered when you bust a conrod.
