    I think revetec engine is crap. sorry.

    I am brave enough to say that in 5 to 10 years time the company will be bankrupt.
    I can explain what is wrong with the design but it would take forever because people will keep arging esp Mr revetec (of course) even if they do not know.

    There are hundreds if not thousands of new engine designs and patents trying to replace the most feasible crankshaft piston engine but none will replace it. A few alternative engines such as wankel (maybe quasiturbine) might be the powerplant in less than 0.5 % of future vehicles. The future would be hybrid and pure electric (fuel cells, battery).

    For those who does not know engineering......
    Believe me time will tell. Even now you can see that there is no interest from major manufacturers. Why wouldn't they just take or license the patent if it is so good, install in their cars and providing customers better products for the sake of their own company. They sooner they can make agreement with revetec the better. BUT revetec has been around for more than 10 years and they are not interested. If Mr Revetec went to mazda to explain his invention and the head of R&D agree with him, why didn't the head of R&D just license the patent. Or borrow a few units for testing. But of course they would not tell if there is any flaw in the design a few days after the discussion because that would hurt Mr. revetec's feeling and Australians might boycott mazda cars. They would not do anything that might affect the image of mazda. They just say NOT NOW.

    Do not just say I am talking rubbish. I even read an article about Revetec in either SAE magazine or Engine Technology International and I think it was in 2004 or maybe 2003. Even the author had a bad feeling about the engine.

    Because major companies cannot allow early patent holders to describe their inventions as it can significantly weaken patent protection in the future. So if say Mazda looked closely at the Revetec engine 10 years ago and said no and then later on an engine patent turned up with even only 1% of the features or techniques then their patent coudl be void. Revetec would then have "Leveraged" a patent value far in excess of it's relvance at the time.

    So that's why majro design and manufacturing groups wait till near 100% proven before going in to technical details -- or they sometimes employ external companies to review and provide reports, but these also have dangers for both parties.
    They just say NOT NOW.
    At least now you know the real reason why "not now"
    Do not just say I am talking rubbish.
    Well saldy, you are on the way businesses today approach novel inventions.
    Even the author had a bad feeling about the engine.
    True and entitled to them and as you already said, thousands of new ideas for engine improvement surface every year. So early on it is hedging the bet to be sceptical !!
    There ARE obvious benefits, but whether they deliver those before material technologies enable the standard layout to match is still a question that Revetec shareholders are betting on.

    I'll just take your word for it.
    Interesting it is your first post. You wouldn't be from Greece by any chance? Maybe related

    Have you read any of this thread? I'm sure Brad covers something about hybrid cars and REVETEC.

    Please direct us to this article so we can read the author's comments. Every article I have read about REVETEC in a magazine has not mentioned any bad remarks from the author and trust me, I have read probably every one in the last ten years.
    BTW the engine of today is much improved on the 2003 design.

    No need to say it. You are doing a good job with your keyboard.

    You must be related.

    Actually I still have the magazine at home. It was from Engine Technology International June 2005. There were many question marks that the author raised about the the unproven claims. And for conclusion even if they can prove their claims there will still be issue about heat rejection. Of course engineers should know that there must be heat rejected form a heat engine. That is the law of thermodynamics. So there will be issue about cooling, AND also cost in general. But even now to me they still cannot prove it. Proving it would not break your company rules, in fact it is good so that others know.

    I know a lot about cars, I am an engineer but not from Australian (not the reason why I have said all this) and I graduated from one of the best universities in the world in Mechanical Engineering. Yes I cannot prove and would not prove who I am. If you do not believe me it is OK. I beleive in my engineering skills and knowledge and I can see that it will not be there.

    Thanks
    We will sort out the emissions when we inject the engine. The Aircraft version is running carburettors (For safety/battery power loss) so the emissions on the aircraft version will be a little higher than they will finally be. Our other injected engines have been very low in emissions, so no prob.

    I can remember the 2000 model. When I displayed the engine at an open day, I brought the revs up to 2,000 RPM inside the closed factory. Everyone was standing in front of the engine. After a few minutes someone said where is the exhaust going? It was pointing straight at everyone behind a mesh grill so everyone could not see it. I removed the mesh and everyone was amazed at the very low exhaust gas flow and everyone had a go at feeling it. One guy put his nose to it and said that he couldn't smell anything. It was quite funny to see everyone's reaction that day. Thanks for reminding me of a memorable moment.

    I can remember the bet about running across the Harbour bridge naked too. Hahahah!

    Your first statement is a bold one. There are many engines in development but they are either complex and costly, or the benifits are small which doesn't make it viable when retooling costs are brought into play.

    The far distant future is hybrid. They still require a power plant to drive a reasonable distance. Battery technology is not cost effective enough currently. The fuel savings of a Hybrid are currently offset with the replacement costs of the battery replacement (normal life) which overall doesn't provide any really cost savings in running costs. The purchase price is higher at the moment too.

    We have signed one contract to supply engines. We are currently going through the testing stage with two major manufacturers, so your comments are incorrect. One has been announced on our website.

    Mazda were interested and a discussion was made about the relationship and licensing. They required exclusivity which we are not going to do. I told them we were planning to manufacture in India and that in a couple of years they could purchase engines of us.

    One question? Are you a mate of manolis?

    What was experienced was a free revving engine at 2,000rpm and the energy required to do this on our engine is very small, so the exhaust gas flow was very small. It was done in an unvented room for a few minutes and no one could smell any fumes. If you are to do this will a conventional engine you would smell the exhaust fumes. I think this was his thoughts.

    After presenting to car companies, universities and all the media coverage(There has been a lot of it over the years) No one has been able to find any fault that I haven't already solved. No one in the automotive industry has been able to find a fault in any theory or designs I have presented.

    That is why companies like Elf, SKF, Recoil Electrosil and Haltech are strategic development partners. I met with Castrol/BP in the UK at their R&D head office a few months ago to present a total overview of or engine. I presented to 6 top engineering professors in all aspects of engines including thermal, mechanical and lube.They stated it was a step up technology and that they were interested in getting involved in our project.

    As for taik a university graduate, So you have read textbooks.
    What is your experience in engines and the automotive industry?
    Who do you work for? Because if you don't work for a major automotive manufacturer, then your just blowing your horn.

    I know a university graduate in mechanical engineering who designs toothpick making machines, and know little about engines as an example that just because you have a bit of paper, it doesn't make you an expert in everything.

    Dear Taik: Here is their article on alternative engines.

    Updated article from Engine Technology International 2006



    The previous article in 2005 was before testing, so i suppose they said they didn't know how that engine would perform at the time.

    Hi Brad, do you know who this is? clue....Are you still going to hold me to running naked across the harbour Bridge when I make my first Million?

    I'm almost there now so this will be icing on the cake and a potential early retirement fund.

    Stop reading this post and get back to work and make me money on my investment!
    Ha ha! Only posting here when I have a spare moment. I do work 12-16 hours a day with 5 hours sleep. I think I'm allowed 1/2 an hour on here every few days.

    If you are that brave then dont use an alias. How about you state your professional name on this quote of yours.

    That is so big of you. Like I have said before, it is insignificant people like you that will make the Revetec engine a success because it is people like you who have no real say on anything of any significance. Consider the question... what if... consider what if Brad has access to data that you dont have access to about his engine. Then maybe he can make claims about his engine that he can back-up when the TIME IS RIGHT.

    There are hundreds if not thousands of new engine designs and patents trying to replace the most feasible crankshaft piston engine but none will replace it. A few alternative engines such as wankel (maybe quasiturbine) might be the powerplant in less than 0.5 % of future vehicles. The future would be hybrid and pure electric (fuel cells, battery).
    You are a nob, have you ever thought that this engine can be integrated within a hybrid powertrain? The most ineffecient aspect of the Toyota synergy drive system is its 1.5 litre petrol engine that weights a tonne. If you integrated Brad's engine within a hybrid powertrain it would weigh less, offer better power and torque and better fuel economy and fuel emissions.
    As Brad has stated he has this technology in the pipeline.
    God blessed you with a brain, try using it.



    For those who does not know engineering......
    Believe me time will tell. Even now you can see that there is no interest from major manufacturers. Why wouldn't they just take or license the patent if it is so good, install in their cars and providing customers better products for the sake of their own company.
    They sooner they can make agreement with revetec the better. BUT revetec has been around for more than 10 years and they are not interested.
    You are a novice and a fool, stick to the how to bake a cake forums.

    If Mr Revetec went to mazda to explain his invention and the head of R&D agree with him, why didn't the head of R&D just license the patent. Or borrow a few units for testing. But of course they would not tell if there is any flaw in the design a few days after the discussion because that would hurt Mr. revetec's feeling and Australians might boycott mazda cars. They would not do anything that might affect the image of mazda. They just say NOT NOW.
    What nonsense is that, it doesnt work that way you fool. It has taken Brad 10 years to develop this engine based on a limited budget and resources. It took Toyota $1 billion dollars and 10 years plus over 800 engineers to develop their hybrid engine. How can you sit there and make such comments.

    Do not just say I am talking rubbish. I even read an article about Revetec in either SAE magazine or Engine Technology International and I think it was in 2004 or maybe 2003. Even the author had a bad feeling about the engine.
    It is too early to cast dispersions about this technology. Dont go making comments or criticisms without having the facts. You are a goose, you are a nob and give yourself a triple by-pass uppercut for your stupidity.

    I didn't realise they handed out engineering degrees at your local McDonalds. Dont be too concerned, if you ever run out of toilet paper you can always use your degree to wipe your a&se. The key concern for you is knowing which orifice to wipe, your mouth or the other hole.

    Media release
    Federal Government Grants
    The Hon Ian Macfarlane, MP
    Australian Industry Minister


    Media Release
    The Hon Ian Macfarlane, MP

    8 January 2007
    QLD AIRCRAFT TAKES OFF WITH LESS FUEL AND FEWER EMISSIONS

    Australian Industry Minister Ian Macfarlane today announced Australian Government innovation funding for a Surfers Paradise company to develop a more fuel efficient and environmentally friendly engine for sport and recreational aircraft.

    Mr Macfarlane said Revetec would receive more than $1 million through the Commercial Ready programme to help bring the product to market.

    "This is a fantastic development and exactly the type of innovation this program is designed to support," Mr Macfarlane said.

    "On top of this, it's great to see that even in the sport and recreation area, Australia’s innovators are looking at ways to reduce emissions."

    Mr Macfarlane said the proposed 2.4 litre combustion engine will use unleaded and JP8 fuel with an output in excess of 82 kw and 262 Newton metres (Nm) while being 25 per cent more efficient.

    Its main competitor is a 2.2 litre engine with less power output. [Contact: Revetec Holdings Ltd, Mr C Chan 07 5531 6059]

    Revetec is one of eight Queensland companies sharing in $1.8 million through the latest round of Commercial Ready and Commercialising Emerging Technologies (COMET) funding

    -----------------------------------------------------------------------

    Note: Only AUD$1.8 million was given out in Qld and Revetec recieved over AUD$1 million.

    I spent a few hours thinking on how to “prove” I am not an elephant. I cannot.
    I was surprised by the “level” of taik’s arguments.
    If taik is not a real person, then he is invented by a sick/disordered mind.

    Follow the best advice Andy Grove of Intel ever took:
    “Base knowledge on facts and analysis rather than on what everybody knows. When everybody knows that something is so, nobody knows nothing.”

    Felix Wankel was nothing but a “high school boy”, an insignificant and poor “self educated machinist”.
    He followed his dream and offered to the world more than many thousands of university professors and overqualified engineers.

    Thank you
    Manolis Pattakos

    PS1
    Revetec, without having finished even the parts of their first X4 prototype (Jan 8, 2007), will take more than one million dollars because their engine “will be” so good. This is what I call success. Congratulations to Revetec.
    Pattakon’s GRECO i3 www.pattakon.com/greco/Grecoi3.exe impatiently waits for the real success of Revetec X4.

    PS3
    Australia is a great county, deeply concerned about global warming.
    Australia has an Embassy and an Ambassador in Athens, and probably technical staff.
    If the Minister of Industry of Australia is an environmentalist like Al Gore (USA ex-vice), he can whisper to his Ambassador to call me to bring, at the gate/port of the embassy, the prototype cars of Pattakon.
    We can run the prototype cars on pure ethanol, if he likes so.
    Have anybody smelled the exhaust pipe of a car burning pure ethanol?
    It smells like a distillery/pub
    www.pattakon.com/vva/VVA_Idle/VVA_Idle.htm

    PS4
    Once again, many Thanks to the Revetec Team for finding the worst flaws and blunders of Pattakon’s PRE and GRECO engines.
    Please keep on with the rest of Pattakon engines in www.pattakon.com
    And according the decision of the Australian Minister of Industry, Revetec is now the State-of-the-Art in Australia.
    From now on, the disapproval of an engine by Revetec has another weight.

    Thanks
    Manolis Pattakos
