Then, how come there is so much soot on the tail pipe of the RX-8. I get 3 months worth of gunk, in 1 week, compared to a conventional engine. Looks like unburned hydrocarbons to me.

 

that has nothing to do with overlap.

You answered your own question, soot is hydrocarbon, and where would it come from?, too much fuel. The tune on the RX-8 is rich.

It was Oswald from the book depository!

BTW what exactly is a book depository anyway?

 

library warehouse

 

Charlie you truly do know all.

 

Granted the renesis is running rich. But if fuel was burning more efficiently and not exiting UNBURNED via the tail pipe, wouldn't the proof be a cleaner tail pipe? Lets face it, Mazda would like us to believe there is no over-lap, there has to be some, however minimal it might be.

 

There is 0 overlap on the renesis. Apart from reading it, I've seen it with my own eyes with a degree wheel; when the exhaust has closed the intake has not as yet opened.

One of the reasons for the soot is the way that a renesis carries unburned hydrocarbons through to the next cycle in a natural EGR type way.

Seal.

 

I'm new to rotaries but what if they went into hybrid territory, let me explain what i mean. The rotary is a modular design and what if they added another section with an electric motor or help out with city gas mileage and low-end torque. I know batteries are heavy but technology is moving fast than ever, regenerating braking, lighter smaller batteries, and I was just saw a title of making power just from heat with certain metals. Our engine produces a lot of heat so maybe that could be an option. Rip my opinion apart but its just and idea to help low end torque and gas mileage (more so city mpg's). Look at other hybrids there city mpg's are better than highway bc of electric motor assistance. And electric motors have instant torque unlike I.C.E.'s. Maybe with the larger displacement 16x engine for highway daily cruising they might be able to do a rotor management system like gm's system (I think the new camaro is using it) of only using certain cylinders while needed (in the next rx-?---one rotor for highway, then two for accel and sport driving). Like i said its just an idea, and thats all any of us have so let me know what you all think.

 

I agree Edwards on the Hybrid concept to augment low end performance. I think it would make a great partnership. The rotary being compact and having high end grunt while the electric motor making low end power. I think that would be a great combination.

 

it all sounds good and everything, i just hate the sound of an electric motor along with the renny. i would rather just have the renny alone as it is. i guess im more of a pro gasoline guy

 

chetrickerman, I can agree with you. I do love the sound of a gasoline engine, especially the rotary. Too bad hydrogen doesn't have as much/more chemical potential energy as gasoline, and easy to produce.

 

Those were just two ideas i had to help with the two downsides to the rotary.

 

well one thing that i dont understand, is that if we are able to make sythetic things like diamonds, and ethonal, why cant we make gasoline synthetically? or at least oil

 

I think we can, but there's no net energy gain from manufacturing synthetic oils. In other words, we put in more energy making it than we gain from it.

If there's a hybrid drivetrain in the next rotary, that electric motor better be able to operate at full discharge under WOT rather than just lending help during cruising and around town like other hybrid systems. Or else, the system would just become ballast during spirited driving, which is what a sports car is designed for, and that's counterproductive to the point of a sports car. To date no hybrid battery has that ability.

 

I'll just nip this in the bud now...

Because it costs more to make than its worth...

Exception with diamonds...that's simply a corrupted market driven price thing...but we all already knew that...

 

or you have a rotary as your power generator to augment your battery system since the rotary can be run at an optimal rpm range and thus maximize your efficiency...

but whatevs you know...the cake is a lie anyway...

 

thats how everything in this world is. nuclear reactors, power plants, electricity all lose power. whether its resistance in the power wires, or friction in the steam turbines in the power plants. i just think that we have the technology to make gasoline synthetically, and that would either reduce, or eliminate our dependence on foreign oil.

 

more than its worth?? how can that be when we spend hundreds of billions of dollars on foreign oil that we could be putting towards making our own. i dont know if its just me, but i think it would cost less than almost a trillion dollars to make our own oil.

 

Not sure what to make of this ......

"Mazda’s next generation Renesis engine, codenamed 16X, was announced at the October Tokyo show and will go into the RX-8 next year and the new RX-7 after that"

 

because you cannot reinvest that entire amount...just "moving it" is unfeasible...but thats another topic...

more than its worth...example...

it costs $10 dollars to make 1 gallon of gas which is worth $1 dollar...

 

ah, i see.well with technology improving every day and if they came up a way to mass produce it, the prices could drop

 

could...possibly...maybe...one day....

by that time tho...humans will have blown themselves up and will no longer need it...

 

very true, i hope im dead before that happens. the greed of man will destroy this world

 

well, there is one way to make synthetic gasoline cheaply. Liquidification of coal. Costs about $20-30 per barrel equivalent. Growing in importance in China currently, because both China and USA has a huge coal reserve. Only problem, infrastructure. The costs of building the new refineries are expensive as with all refineries and it it not known how long these gas prices will remain high. Companies are reluctant to invest.

Not new technology. Germans during WWI and WWII used it and South Africa during the apartheid economic sanctions.

 

AND the fact that we will keep mining for the coal, and in turn, dig up more habitats and ruin the environment. like i said, the greed of man will end this world. i see earth becoming a mars in a couple thousand years
