It was a tremendously fun car to drive. It was the muscle car era, and I got a kick out of blowing the doors off of guys who thought they had a hot car. The brakes did not match the engine, and I got tired of replacing shoes. It definitely went much better than it stopped.

As it stands right now, you're not wrong, but don't hate on our passion. I personally love the RX-8, but the rotary from the earlier RX-7 was better built.
@shananagans53 жыл бұрын
@Joppa Kolla I had one back in the 80s. Everyone here is right about the problems but they were great fun. They were pretty low on torque. I don't know if that's due to the rotary design or the small displacement but once you learned to keep the revs up, the original RX7 was a light, predictable little car that handled pretty well. They were great fun on a twisty mountain road. I even considered running a rotary in my desert race car. I didn't ever do it because someone beat me to it and they had lots of problems. The weight savings was offset by having to carry extra fuel and the seals were lucky to last 500 miles in dusty race conditions. I wouldn't want one again unless they can figure out the issues but I totally understand why some people are fans. I did want some more power in my RX7 but it's hard to think of a car in the 80s that was more fun than an RX7 on a mountain road.

I like Mazda's idea for making the rotary engine a range extender for electric vehicles. If they fit it with direct injection, it can have higher fuel efficiency and power. Since the combustion chamber is separate from the intake chamber, the injectors would stay clean for a longer period of time. Direct injection makes more sense on a rotary engine vs a standard combustion engine.

The rotary engine makes sense as a generator, as it does not need the power bands that a directly connected engine would have to have. All it needs to do is run at a certain RPM.

There's no oil sump in a rotary engine; instead, there's an oil injection system that shoots oil into the chamber on the intake stroke. That's shat leads to abysmal emissions numbers. Another bad aspect of the rotary is differential heating: the intake half of the engine is always quite a bit cooler than the exhaust half. This leads to problems keeping gasketed surfaces from leaking. Despite all this, it is a fascinating engine with only three major moving parts (two rotors and the eccentric main shaft). I've always wanted to install one in a drag boat.

Scotty: In the 70’s I drove a Mazda Cosmo for sales work all around the eastern USA. It did a great job and was fun to drive. When Corvettes laughed I had fun smoking the (up to ~ 90-100 when they finally overtook me. Of course I was loaded with suitcases and engineering samples, so it was hardly a fair contest. Mazda gave me an engine transplant at 80,000 miles. After another 20,000 miles I sold it for what I paid for it. My family drove an RX-3 and RX-4 during those years, too. Yeah, I had to maintain all of them myself because the Mazda folks just couldn’t set up the triple ignition system (leading, training and high speed). Tuning the carburetor and afterburner was done by smelling the exhaust. When the gas smell went away it was tuned right. Good car! Didn’t owe me. Nickel!!!
@richardpope95843 жыл бұрын
I owned a 73 RX-3 that I bought for $50 with aluminum mags on it. The engine, trans, and tires were trash. I rebuilt the whole car from the ground up. I pulled a 13B and a 5 speed manual out of a wrecked Cosmo with 10K miles on it. I took the engine and trans apart and did my voodoo on them that I do so well. It was a full bridge port engine with bolted rotor gears and harden stationary gears. I massaged the syncros in the trans so that I could quick shift it. I then put a Airresearch TO-3 with custom turbine and compressor wheels on it and used a Holley 650 double pumper to supply the fuel. I installed a 4 row radiator, Holley high output fuel pump, limited slip 4.93 rear end gears, koni shocks, lowered 1 inch, traction bars, 225/60 TAs, custom interior and royal metalic blue paint. It was making 15 lbs of boost at 3K rpm and 250 lb/ft torgue. At 11.5K rpm I was making 500 hp. 13.1 at 110 mph in the quarter with the TAs. I had to use two waste gates. I also put quartz halogen lights, fog lamps and aircraft landing lights on the front end. I installed a Chrysler 100 amp alternator to supply the electrical needs. I installed a custom center dash with nine Steward Warner gauges in it. There were WT, OP, FL in the top row. The middle row had Volts, Amps, Boost/Vacuum. The third row had FP, OT, and ET. I put a 10K Tach and 160 mph Speedo in the instrument cluster. I owned this car for 15 years and drove it 500K miles. I had to overhaul the engine every 100K miles. I never had any problems with the apex seals. I would lose the side seals or seize a bearing if I missed a shift and over revved the engine. I considered 100K miles a good lifetime considering the amount of power that I was making.

@Arturo Eugster, it was more about emissions. Lots of NOX emissions something to due with distinct hot and cold sides of the engine. Mazda is putting a new rotary in a hybrid as a range extender with direct injection and some weird variable timing techniques. Ends up being smoother, quieter, and more efficient than piston engines. I think they plan to run it with limited RPM range.

As an extra, they had a newsfeed on latest inventions on electrical, electronics and mechanical advances. The Wankel was already invented at the time and I read about it. All the advantages over the conventional piston/crankshaft was already so obvious at the time. That was decades ago and I am 68 now, still wondering why and how the heck isn't it still commonly around as the solar-panel which was also already around since my teen days?

I think I might include the lack of the entire valving system, with it's many many parts as another one, even moreso than the crank, especially when push rods, rocker arms, etc were included. This one opens ports like a 2 cycle piston engine, but doesn't use all the downside piston pressure to help flow air/fuel. You've got a lot of statistics all screwed up in here, especially if you are talking about Rotaries in the 1979 and up time frame. Novella follows: RX7s typically went 130k to 150k miles, even with very hard driving, so your 60k average service life, for later rotaries is WAYYYY off the mark, fairly typical for American V8s of the time, though the Japanese engines typically went MUCH farther. On earlier rotaries, rotor seals DID have lousy life, about the life you stated or a bit less (50k, IIRC), but Toyo Kogyo put a couple million man hours, as I understand it, into redesigning them (materials changes, sprung multiple piece apex seals, to accommodate short side end wear much better, etc), as and they got MUCH better after that. There was certainly no 'nail in the coffin' mid 70s, except with American manufacturers. The RX7 came out in 1979 and I think it outsold EVERY other sports car combined, at one point. Not exactly 'in the ground' yet. Reading junk, and actually living it (meaning an enthusiast) often provide very different 'histories', one real, and one often contrived by marketing people. Remember the 'piston engine goes boing boing boing, but the Mazda goes 'hmmmm". That one was actually funny, as are a small percentage of others. Some YTers are doing vastly better jobs promoting products than the pros EVER did. :-) I have a piston driven TL I'm currently driving with 311k miles on it. It has had NO engine work other than valve cover gaskets. Still burns no oil, oil still honey colored, inside absolutely pristine except for a very light discoloration staining that wipes off with a finger. I have pics when I did the valve cover gaskets at 309K and I can take a current pic of the odometer if you are having any trouble buying this. My older Camry has 275, my son's corolla is right at 300, etc. And several of these (not the TL) were not exactly well cared for. My first RX engine went 135k to an oil leak on the upper transfer passage, at that stupid oil ring that is a common failure point. Still ran great, I'm certain I could have put just seals in it and it would have gone MUCH further, but went to a four port and the hop up path at that point. I didn't realize all the American manufacturers that built cars using them. My family and I owned a few RX7's, great car, tons o' fun. I did some hop up work on a few of them, street porting, higher flowing dual carb Webers, intake, headers, hardened rotors, welded and staked stationary gears, high flow oil pump, and several etceteras. Made a 250 hp normally aspirated 13B. Very simple engine to work on. Also, driving the RX VERY easily, on the highway, I once obtained over 30 mpg, but that is not remotely normal. Specific fuel consumption is a good bit higher than a typical piston engine of the same output, but I think I averaged about 17 mpg with normal driving on a 1984 13B. If you drove them hard they got much worse, just like every other ICE out there. One (silly) example of exceedingly different scale motors was where Top Gear pitted a lambo (or something equivalent, some supercar) to a Prius, requiring the Prius to run wide open and where the Lambo was obviously loafing while 'keeping up', and the Lambo got better mileage than the Prius...yeah, stupid, but it does, at the limit, support what I am saying VERY well. Also, the rotaries were reclassified in almost every form of racing they were involved in, as the HP available from the rated CI was not really apples to oranges, and they were absolutely dominating their classes, to the point of absurdity. Some guys took one to an endurance race that they'd bought for something like $3k used, did nothing to the car except change out fluids in the tranny and rear end, hop the suspension, and build a killer new engine for it. They had $10k total in it at race day. At the briefing the official noted that the rotaries could be so loud on trailing throttle that they had been known to break windshields. Some gentleman racing some ultra expensive exotic (about $200k out of the box, new, IIRC) said snidely "I don't think we'll be having that problem". When RX went by them they were doing in excess of 175 mph, and they took first place in the race, and IIRC by a large margin. Back to the drawing board, clueless Germans (my snide remark, and I'm talking about THOSE particular Germans, obviously the original Wankel design WAS German, and they are amazingly good engineers, as a people). See WWII...V1, V2, Me262, and a lot more. So the moral of the story is, don't get TOO cocky when some very low budget (about 5% in this case) rice rocket pulls up containing some very competent engine builders, because you might get TORCHED, and have to retract your smirk, or eat your words. Cheers, Scotty, good vid overall. Guess it's pretty obvious to anyone who has gotten this far that I was thoroughly smacked with the 'rotary bug', though piston configured ICEs still have a large place in the old heart, as well. Several restos and builds there for me, as well...4 cycles, and twos. My favorite was the 70 Cuda I did, unfortunately not a 426 hemi, though, that would have been stellar.
