Sorry but it is an oxidant all on its own. Maybe you didn't read the wiki article??? And again I never said that combustion needed to be a form of oxidation anyways. I have only stated the definition.

The production cost of our current trike engines are confidential, however we are selling performance replacement units for between AUD7,200 to 9,500 depending on final config. We have a target price set for the Revetec X4 trike engine, all indications show that we will meet this price target in production. Unfortunately I can't reveal the price. The ultimate outcome is to have the engine manufactured in China. Last edited by GTM; 03-03-2008 at 03:49 PM. |

I learned the difference between combustion and oxidation in school. The fact is that the chemical reaction between hydrogen and oxygen resulting in water is combustion whether it makes a flame or not. I ask you again: Do you agree that cellular respiration is a form of combustion (commonly known as Slow combustion)??? answer the question please.

Wikipedia is great. The problem is that you or I can modify it. GO to an encyclopedia resource as I did with: The Columbia Encyclopedia, Sixth Edition | Date: 2007
Wikipedia search on cellular respiration had no combustion terms in the article. Last edited by revetec; 03-03-2008 at 04:12 PM. |

so back to revetec...how is the development and placement into actual vehicles going?

ht, you sure you're not getting yourself wrapped up in your own confusion ?
Combustion is fast oxidation. where have you come up with "slow combustion" ? So as Fiorano added ... let's get back ON TOPIC>

Don't get the singular term "Combustion" confused with the term "intracellular combustion". If you want to go down this path, start another topic on a biology forum because it will go on forever.....

Matra & revetec: I asked a simple Yes/No question.
Do you agree that cellular respiration is a form of combustion (slow combustion)? Quote:

We already stated the difference between slow oxidation and rapid oxidation.
ICE have rapid oxidation (which produces a flame/burn, and fuel cells have slow oxidation). Fuel cells has "intracellular combustion" and ICE has "combustion" Fuel cells do not have a flame/burn so I will accept you stating that fuel cells have "intracellular combustion" but not "Internal Combustion" as you stated. You can go on and on about it, but in an automotive sense (and everyone viewing this thread being automotive orientated) as referring to a fuel cell as being internal combustion is rather pedantic. I'm not going to enter anything more on this. If anyone else wants to comment on this, go ahead... Last edited by revetec; 03-04-2008 at 12:08 AM. |

It would be Great (envy) to be the First to bring a Revetec engine to market place. ![]() I found over half a dozen of your Trike sites when searching google. Was wondering approx. how many trikes are sold world wide ? I assume you are the only Ozi outlet ? Also, approx. how many Trikes would we turn over in Australian ?

Brad, on a slightly different note about the engine, with some reference to what was said a while back about the gearing of the output.
Your engines now are geared up 3:1 to provide a normal output, so a normal set of gear ratios suited to a small petrol engine can be used in a road going vehicle. Obviously the standard output couldn't be used for this with say a 2000rpm redline, but how would you predict a vehicle would perform if the Revetec lump could be made to rev to 4000rpm un geared (12000 conventional) and coupled to a long ratio gearset suited to a high revving diesel? I'm sure you must have given some thought to something along these lines but I couldn't get my head round whether or not that would be a good combination? Obviously talking purely from a performance point of view here now, not fuel economy sorry! If anyone has any thoughts on how this combination would work I would love to hear your opinions! |

Kozy: I think you have it backwards. You got drive off directly off the trilobe then 1 stroke would take only 60 degrees of output shaft rotation.
Currently revetec uses a seperate geared output shaft that has a 1:3 ratio (not 3:1) so that 1 stroke of a piston now takes a more normal 180 degrees of output shaft rotation. This means that when the revetec is running 4000RPM with the geared output shaft it is running like a normal engine, however without the geared output shaft then the pistons and valvetrain have to run faster. To produce 4000RPM at the output shaft the pistons have to achieve the velocity that a normal engine does at 12000RPM, same with the valvetrain.

There are engines out there that have revved to about 18,000rpm which means it is possible to reach 6,000rpm on the trilobe shaft.
Two things though: 1) We don't have a Formula 1 budget to even consider this at the moment. 2) Our engine exploits low down torque and is most fuel efficient at this point. The industry is driven by fuel efficiency and emissions these days. |
