A work of pure genius! - Brilliant "Revetec" Engine

[Jax]

I apologise for my lack of manners. I will gladly discuss the attributes of the pulse turbine hybrid however the variable axial hybrid shall remain a mystery for the time being! The pulse turbine hybrid works on thoeries similar to pulse detonation technology. Dual inline centrifugal compressors compress a charge into a circular array of cylinders. Fuel is added obviously, then the normal bang follows. The resulting expolsion powers a centrifugal turbine. The power needed to reach a suitable compression ratio is provided by a centrally mounted motor/generator. This motor/generator powers the vehicle until ignition takes over then battery charging occurs. The charge is controlled using an induction and exhaust disc valve system. In cruising mode opossing cylinders can cease fuel and ignition operations without throwing around a usless piston. Would you like to hear more???????

That's all fine and I understand pulse turbines. They are good for uses which maintain a certain RPM but not really suitable for vehicles with a wide operational range and responsiveness required for them. Maybe your described cylinders should be referred to as combustion chambers? As a cylinder will confuse some people thinking there are pistons?

The combustion chambers are cylindrical, therefore I shall call them cylinders!!! As for your lovely little picture, the pulse tubine hybrid look nothing like that. The minimal acceleration lag is compensated by the electric motor. I would like to know what makes the revetec engines better than such engines as what BRD srl produce or the shane engine or even the piston rotor engines!!!!!

revetec, i'm curious about the future development of your engine.

What do you see as the next big step in development? Would it be for instance the adoption of a multivalve/OHC layout?

What sort of investment ($$$) would you feel necessary to get to such a stage? I recall hearing your current work has been performed with a $1M government grant, which you had to match leaving $2M.

The grant was purly for the aviation engine. Our previous 2 engines were 4 valve per cylinder engines. We are currently revisiting the automotive market at the moment, and we have learnt a lot from the X series engines to increase efficiency of the following designs.

All of the engines you have identified are working on the same type of basic principal, and show merit. The benifit we have over those engines, is that we deflect side thrust to rotational force with the counter rotational cams. Not only does this increase efficiency, but also increases reliability. This is because when a bearing pushes on a cam, and the angle of push is over 30degrees from the piston stroke centreline, the side thrust greatly increases. We are push up to 45degrees on each cam compounding either direction to 90deg. One of those engines controls side thrust with a pivoting lever, but that also adds to reciprocating mass.

Cheers

Bravo revetec!!! This same princapal I myself had problems with in the early stages of the piston rotor engines. I would also like to note that the X engines designed by BRD would blow the sump off on the down stroke due to over pressurization of the crank case. I myself found that a V model at 135 degrees of seperation was the best senario.

Hehehe! Haven't you looked at the designs at all.

While those engines have both the pistons compressing the crankcase, you will notice our engine has both pistons on oposing cylinders travelling in the same direction creating no change in crankcase pressure other than gas lost past the rings.

And note: We use perfect seal gapless rings. So your comment is not very well thought out before posting it. You have just also identified a design fault in the other engines to everyone, and admitted you spent time on a design that had inherent faults.

We are ALL looking to REAL testing !!!
Not the Bravado !
You say there are no weaknesses, other than gaining engineering perfection !!!
So, has there been no real testing in ANY 4 wheel vehicle ?
It appears ALL the previous engines have only been fitter into a Tonka toy trike.

As a matter of interest, what happened to ALL the previous engines we were told went over for MOU ?

What do Revetec envisage for a budget to FINISH a automotive engine ?

Have you organised a meeting with "Kevin-07" ?

Vision is expected !
But nothing expected.

Plan NOTHING and succeed at NOTHING !

[Matra et Alpine]

STOP raising business issues here.
This forum appreciates the discussion but demanding that an answer is required in a public forum is plain stupidity.
Brad has already pointed out on numerous occasiosn the correct procedures for those types of questions.

Think NOTHING and ...... think ....... nothing !

Real testing? Independent testing at Orbital was Real testing. In car testing can't definitely prove fuel efficiency as there are variables that cannot be controlled. All car companies do testing in test cells before even thinking about fitting an engine into a vehicle.

We are working on the car companies at the moment. I don't think GTM trikes would take kindly to you calling their quality product a Tonka Toy. As you are a shareholder, I'm appalled by your comments on a good client of ours.

No budget at the moment, I'm working on it when I have the time. I'm getting a model ready for presenting to automotive groups.

Doesn't he keep you in the loop? I'm meeting with him when he gets back from OS.


One thing I should comment to "Revetec Raptor" at this stage:

Dennis Monamy aka "Revetec Raptor" has registered revetec.com.au
As part of the domain registration process, you would have signed the domain registration agreement. As part of that agreement you have to show via a signed submitted document that you are entitled to attain that domain.

You are not a part of the Revetec management entity, and the only document to satisfy them is your proof of shareholding. While this may have qualified you from the domain registration process, it does not entitle you legally to register it.

The Revetec name has a copyright in our related business fields. The website you have registered has had a website referring to our engine without consent. This is like you buying shares in CocaCola and thinking you are entitled to register a cocacola domain.

Please visit: Trade Marks, Domain Names and Passing Off

As part of the domain registration I will quote:
" To be eligible for registration in the ".com.au" space, a domain name must be directly derived from:
* the commercial name of an entity which is registered or licensed to trade in Australia; or
* a trade mark which has been registered or is the subject of an application for registration by the entity.

Holders of .com.au and .com domain names are generally required, as a term of the licence, to warrant that registration of the domain name and its use will not directly or indirectly infringe the legal rights of a third party (including copyright and trade mark rights). A breach of the warranty would allow the relevant licensing authority to terminate the domain name licence."

I have downloaded the registration form and have forwarded it to our legal council. Also a copy of the website has also been forwarded.

I'm giving you notice of seven (7) days to take down the website and to deregister the domain. If this is not completed in that time frame, you will be notified by registered mail that the the matter will go before the auDA Administrive Panel and pursued in the small claims court. Damages and Revetec expenses will also be claimed at this point.

This breach of our copyright also extends to your own website/s and postings of Revetec materials, which must be removed immediately.

Any further breach of copyright or unfounded deformation towards our company from you in any way will be dealt with accordingly.

You can respond via email directly to me if you require, on any issues you may have.

Sorry everyone, I just want to talk technical on here So let's get back to it.

I take offence to our trikes being called a "tonka toy"! There are many of our customers around Australia and NZ that are very proud of their trikes. The average trike costs over $45k and many of our customers have worked all their lives to afford their trike.

What is your agenda here? It is not the first time you have slanted our product or our support for Revetec.

Over the last four years we have supported REVETEC and provided them with brand-new trikes to demonstrate the Revetec Engine whenever they have asked. We have never refused Revetec's requests nor charged them one dollar for our trikes despite it costing us hundreds of thousands of dollars to do (capital we could easily reinvest in our own R&D or production). Our actions were done out of support for the Revetec technology, the company and Brad.

Brad contacted me this morning, he was very concerned about your post (coming from a shareholder of Revetec) publicly slanting our Trikes. Brad was concerned that your post may damage our relationship with Revetec, and rightfully so. However this is not the case, we continue to offer strong support to Revetec.

For the last two months we have been developing a new trike specifically for the Revetec X4 Engine that includes a 5-speed transmission (upgraded from 4speed, the 5th gear will yield 100km/h @ 2,000rpm inline with the X4 engine sweet spot for efficiency), all carbon fiber chassis and body work (reduction of 60kg), underbody mounting for the radiator etc. etc. This has been developed from the ground up and required new designs, components, moulds, kevlar honeycomb, aircfraft grade carbon fiber prepreg materials etc., all done at no expense to Revetec. This was done so that the company has a very unique combination (Trike and X4 engine) for further promotion.

We look forward to having the new trike ready in about 1-2 months.

[Matra et Alpine]

Guys, we are reviewing this issue.
He's clearly not listening to our requests to act sensibly.

I personally appreciate the time and willingness Brad shows to share technology with us and it's good to see a trike manufacturere here to .... though I have to put my hand up and say I love Grinnals as mates have a BMW and a Triumph one

Don't want to lose you guys and your inputs. So watch this space and avoid the idiots !!

i am looking foward to seeing this, sounds intriguing. and with today's fuel prices
