Is hydrogen's future in the hands of Mazda's rotary engine?

As any regular reader of our site is aware, there are many issues with the notion of using hydrogen as fuel which need to be overcome before there is any chance that you'll find yourself refilling your new car at a hydrogen station any time soon. Not the least of these is the fact that there are almost no hydrogen stations in the first place. Also, whether the hydrogen is used in a fuel cell for an electric car or burned directly in an internal combustion engine, there aren't actually any hydrogen-powered cars available today which you can just go out and buy. Mazda may soon change all of that by introducing a hydrogen-powered rotary-engined RX-9. According to Auto Express, the new car will be dual-fuel capable, with clean credentials coming from hydrogen and performance credentials coming from gasoline. Amazingly, the article claims that Mazda's hydrogen RX could be ready for sale as early as 2012.

Well if they could work out the hydrogen and internal combustion engine, wouldn't be a problem, Hydrogen emits water, not CO2.

Are you saying it can't pass the smog test?

Effeciency depends on how it's measured. 1.3L @ 215hp is pretty efficient. Now, 215hp for 21mpg (freeway) is NOT efficicent.

WRONG!

[edit] Fuel consumption and emissions
In Mazda's RX-8 with the Renesis engine, fuel consumption is now within normal limits while passing California State emissions requirements. The exhaust ports, which in earlier Mazda rotaries were located in the rotor housings, were moved to the sides of the combustion chamber. This approach allowed Mazda to eliminate overlap between intake and exhaust port openings, while simultaneously increasing exhaust port area. The Renesis engine even meets California's Low Emissions Vehicle or LEV standards.

I didn't say that it didn't work, just that it's inefficient, as in consuming too much fuel and not burning it completely.


....

Effeciency depends on how it's measured. 1.3L @ 215hp is pretty efficient. Now, 215hp for 21mpg (freeway) is NOT efficicent. Wow- you need a LOT of education about engines (not to mention basic English). Efficiency is only measured one way: work done / heat energy of the fuel.


my son would disagree....he is rebuilding a 93 RX7 right now.... He can disagree all he wants, but he'll be driving fewer miles with his hard earned dollar.


Just as the shape of the Wankel combustion chamber prevents preignition, it also leads to incomplete combustion of the air-fuel charge, with the remaining unburned hydrocarbons released into the exhaust. …However, the less effective sealing of the Wankel is one factor reducing its efficiency, confining its success mainly to applications such as racing engines and sports vehicles where neither efficiency nor long engine life are major considerations…http://en.wikipedia.org/wiki/Wankel_engine#Fuel_consumption_and_emissions

Right....because cars/engines are NEVER judged for "FUEL EFFICIENCY"....or any OTHER efficiency.

wow.

Here's the deal - Based on Horsepower per Litre, the engine returns very nice gains. That's efficient. It's efficient in terms of weight and space-saving, too.

I can't believe mazda ever 'only' used rotary engines across their line up. If you look thru their line, historically, (I can't find the data) any car starting with a letter other than R was a Piston engine, generally. They did have a rotary-powered pick up AND Bus, though.

Why did he add a turbo to it? 93 RX7s were all turbo'd from the factory. Did he do a single turbo conversion (from the stock twin-turbo set up)?

The turbo will only HELP the engine's "efficiency" if that's what he's after.

One reason I didn't buy an Rx7, however, (I was shopping 93-97 models) was because I'd seen several posts on their forums which amounted to:

"Hey y'all! I've made it 60,000 miles without the apex seals going!"

Replies:

":bs:"

:)

While there have been plenty of advancements in apex-seal and tuning technology, folks with built-up Rotary engines should be prepared to replace stuff. Rotary engines, specifically RX7s, left stock can run very well, for a reasonably long time w/o major problems.

In my mind, everything the sold in the late seventies/early eighties was rotary. Obviously this perception is wrong, but that's the way it seemed to me. Maybe it was due to the popularity of their pick-ups.

Ford bought the concept from the inventor (Wankel) back in the 60's, spent millions on it, realized that it had efficiency and emissions problems, so sold it to Mazda for 49% of their stock. Mazda marketed the technology and was initially successful, then scaled it back to only their sports car (which is really just a “sporty car”). (I'm sure someone here will pick that apart and find a slight error in history and bash me with it, but so be it- the nuts and bolts of the matter are factually correct.)

In any event, inventors have come up with all sorts of internal combustion engine configurations, all of them based on the simple principle of compressing a fuel air mixture, igniting it, and pushing the exhaust out while collecting mechanical energy. These range from a positive displacement (piston) to a pure axial configuration (turbine), and each is efficient only within a defined rotational speed (rpms). The Wankel engine is close to the piston engine within this range.

The power to weight ratio tends to increase substantially over this range. On the high rpm range, the turbine, and its purely thrust only sister jet engine, can develop huge power/ weight ratios. Darin is confusing efficiency with power to weight ratio.

The Wankel has the inherent problems of sealing between the rotor and the stationary chamber. When the engine runs the rotor tends to heats up faster than the chamber. Plus, at the same temperature difference the smaller rotor “grows” less than the larger chamber. Initial designs developed problems with seizing when the rotor got hot and “grew” too big for the chamber. Designers solved this problem by building the rotor out of iron and the chamber out of aluminum (which “grows” larger than iron at a given temperature difference).

Mazda’s done a great job tinkering with the configuration using different materials and such, but have never achieved the efficiency of the old piston engine. The piston has rings that seal against the cylinder, and the rings are basically springs which keep an even seal as the piston heats up differently than the cylinder. I always figured the Wankel engineers would try and configure some type of compressible metal between the two parts to act as the “ring”. Maybe they have, as I have not been following along with their developments.

Maybe Darin the self proclaimed “car guy” can enlighten us on current technology.:coffee:

I dunno. I mean, I'm scared of Mazda; after dealing with my RX8. Although I bet MOST car makers try to avoid warranty coverage of their products. I've had a LOT of crap to put up with on the rx8 re: getting warranty coverage.

For that reason, I'll likely never buy another 'new' mazda. I'm scared of the quality of worksmanship. Another mazda thing that bugs me: They seem to think adding power to a car automatically reduces the subjetive handling capability of the car. :(

2. No net search required. The source of my information is from fluid mechanics, thermodynamics, materials science coupled with my practical knowledge of engine technology. Maybe you can “google” some of the terms that I used and prove to yourself that some of us are capable of original thought.

1. Current sealing technology, silly boy! I guess I gave you too much credit.
2. No net search required. The source of my information is from fluid mechanics, thermodynamics, materials science coupled with my practical knowledge of engine technology. Maybe you can “google” some of the terms that I used and prove to yourself that some of us are capable of original thought.
Wow I got a neg rep for this post? :lol:

As well as this one. Wow.


I didn't say that it didn't work, just that it's inefficient, as in consuming too much fuel and not burning it completely.

Wow- you need a LOT of education about engines (not to mention basic English). Efficiency is only measured one way: work done / heat energy of the fuel.

He can disagree all he wants, but he'll be driving fewer miles with his hard earned dollar.

Why would you dig this up? Thought you wanted to be here and avoid confrontations? Wasn't that your bill of goods?

Look, I like you and if you don't know that by now you never will. Coming back and digging up a post that refers to an administrator is not the way to segue back.

BTW, I don't find your condescending use of 'teach' cute in this context.

I dunno. I mean, I'm scared of Mazda; after dealing with my RX8. Although I bet MOST car makers try to avoid warranty coverage of their products. I've had a LOT of crap to put up with on the rx8 re: getting warranty coverage.

For that reason, I'll likely never buy another 'new' mazda. I'm scared of the quality of worksmanship. Another mazda thing that bugs me: They seem to think adding power to a car automatically reduces the subjetive handling capability of the car. :(Sucks to hear that; I've had nothing but smooth sailing every time I've had warranty or recall issues. Then, mine was an 05, not the dreaded 04. And also, the color has been scientifically proven to be better than yours. :poke:

Why did he add a turbo to it? 93 RX7s were all turbo'd from the factory. Did he do a single turbo conversion (from the stock twin-turbo set up)?


not auto tech enough to be able to answer.....when he bought the car it was delivered with the engine in about a dozen different boxes....somebody had been doing a restore job and had failed and he bought all the pieces for $10k....I know he put in a non-stock turbo, because he had to design mounting brackets for it and have them custom made....I also know he is frustrated with it......he's gotten it all together, but currently, if he drives over 40 mph his turbo starts blowing oil all over the street....

does this help answer the question?
