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

[revetec]

Probably just a typo or oversight, but GTM trikes is not a shareholder in Revetec, they have signed an agreement to buy engines off us as a client. They have driven a trike with the X4v2 engine and are a very keen supporter. I think you meant forum member? Is that correct? Cheers

But there are quite a few long term shareholders here, one of which has actually signed a deal to get the engine in his trike, which support all actions taken by Revetec.

Cheers, I don't mind getting hassled about the company (It's part of my job to get questions or gripes thrust apon me to answer), but this is not the correct place to do it. It's a Technical Forum. Every shareholder can ring me and voice their opinions, or if they want to do it publically, our Annual General Meeting is the correct place to do it. Then I will be put on the spot face to face to respond in front of all attending shareholders. Even if you cannot attend, you can ask someone else to ask the questions for you with giving a proxy to that person, and vote on your behalf as well.

Regards
Brad

Doh!!!

I did know that GTM wasn't a shareholder. I meant that one of the forum members supporting Revetec actually has a deal.

Was the article published last month, or 5th of July?

I'm not trying to nit pick , but the majority of people reading the news article would believe/understand Toyotas Hybrid uses 236g/kwh as a complete system, when its for Engine only.

And so is ours is Engine only @ 207g/(kW-h).
(Prius engine 34.7% - Revetec X4v2 engine 39.5%)

I don't write the media stories, I give comments and responses in an interview which are "Quoted".

You're still not impressed with the figure we got with a two valve, push rod head are you?
Oh well, can't impress or satisfy everyone. The figure will only get better using the amount of top end technology they are using. Cheers

Hi all,
New to this, do have a question though?????? Is it possible to have a 4.4L piston engine that is internally supercharged, has a 50kw motor/generator internally, has variable cam timing as well as varible compression ratio, does four strokes per revolution and is 60cm long and 45cm wide?????????????? Has anyone heard off such an engine?

When is the next AGM being held? I have been out of the loop for awhile and want to find out what has been happening and what's going on etc.

Why do you keep leaning on this dubious fact?

Yes it is impressive that your engine achieved the BSFC figure that it did, but constantly going on and on about how it will be better if it had the same top-end tech as japanese automotive engines is simply not warrented.

How do you think 4VPC, and cam-phasing is going to increase your BSFC?

I find it interesting that they choose the engine in the Prius as an arbitrary "second best" engine when it comes to BSFC. It would be interesting to see where they got there value of 236g/kWh from. The engine in the Prius is toyota's 1NZ-FXE and it uses the atkinson cycle (which gains some efficiency through asymetric cycles).

BMW has released interesting BSFC figures for it's new 4 cylinder diesel engines (as low as 198g/kWh note:that is grams diesel not grams petrol so only 40% efficiency). It will be really interesting to see what BSFC the new petrol 4 cylinder engines can produce...

BTW: I hope you are planning on retesting the your engine once you have redesigned it for automotive purposes???

I have to admit the revetec engine is somewhat unimpressive compared to the likes of the pulse turbine hybrid engine and the varible axial hybrid engine.

[revetec]

Hightower: I don't want to go on and on about it. The engine was designed as a basic aviation engine, and the top end is resonably antiquated. We know from testing that we have alot to gain from improved head design.

Jax: Good comment, I applaud you. I'll look forward to seeing your daily driver with a pulse turbine hybrid or axial engine in it.

RVC Shareholder: AGM is after audit, as it is every year.

Cheers

Jax, please rather than posting random unsubstantiated points here, if you think there is better technology out there thne please create a thread and provide a full explanatino of the operation of the engine and the advnatages it brings and the known disadvantages it has.

THEN you will be contributing positively to the forum.

thank you
