New project - GERT
Benzine - 9/2/11 at 10:59 PM

For a while now I've been thinking about a new project. It's not a CEC or a BEC, but a GERT. I've now started to collect some parts and got planning. Can you guess what it yet?

Generator Engine, Rotary Turbine?

Mr Whippy - 9/2/11 at 11:07 PM

odd engine, for a small hovercraft maybe? ground effect racing...hmm something?!

blakep82 - 9/2/11 at 11:07 PM

is the TK getting some kind of engine upgrade?

i'm only assuming T means truck, maybe, but haven't got a clue about the rest...

you've not bought a bus have you?!

a something Engined RT

The TK wouldn't move with this engine in it One cylinder of the TK is more than this whole engine lol



MakeEverything is closest, Generator engined reverse trike m/ single seater with a 2 cylinder lombardini diesel engine

No, but now I want one of those too

Or Gas Electric Rotary Turbine?

Mr Whippy - 9/2/11 at 11:15 PM

clunky, I have several similar 1 cyclinder engines for dump trucks and mixers and they are crude, but saying that simply never fail to start even after forgetting to check the oil. Always something very satisfying in hand starting these little engines too

What's the max RPM? ususally they are very limited and designed to run in a narrow RPM window

you don't want to make a start on my next project instead do you?

I love small thumping derv engines ^_^ 3000 max

that'd be mental, do it

I suppose really I should finish my kit car first, and I am doing that at the same time as this, and I'm welding up the amazon too. I like having lots of projects on at the same time (even if I have v little spare time) If I get bored/fed up/annoyed with one there's always another I'll be interested in working on, so when I do get spare time I always make the best of it



==>Some bikes with lombardini diesel engines in <==

certainly tonnes of torque, you might find you just don't go very fast

flat out these engine almost shake themselves to bits, might be worth getting it balanced or doing it yourself though over reving it might simply snap a conrod or the crank

Interesting project, lets see more you must have a doodle

Originally I was thinking of using a single cylinder but that would have struggled up hills. This lombardini has a few more horse power than an Aixam (4 seater with a 2 cylinder derv engine) which weighs 400kg, i'm going for as light and aerodynamic as possible, will be significantly less than 400kg. Oh and as for going fast, I'm not going for speed but economy, 55mph will do fine!

I can't find any sketches at the moment as I did them on envelopes and can't find them, might have another doodle soon

You not seen his sig? Note the number of Volvo's

kipper - 10/2/11 at 09:58 AM

I don't know what yours is but I Have just bought a lister CS engine. 6 HP 650 revs per min, they tell me it will run on anything oily, rape seed vegy ,chip oil derv.
It is only slightly heavier than a Pinto

Quiet, you

fazerruss - 10/2/11 at 05:30 PM

we have an engine thats much more simple and crude than them modern listers ect. I cant remember what make it is but its about 80 years old and will probably run on owt that slightly flamable ( wet farts, petrol ect). Its green, has two 18" flywheels and fires about twice a second. Beat that for low rpm torque!

A friend of mine had an Aixam. It used the same Kubota diesel engine as the fridge units that you see on chiller lorry trailers. It would manage 70mph with a tail wind but it was governed and if you took the governor off I bet you could get more out of it. It was a bit of a stretch of the imagination to call it a 4 seater though

Benzine - 18/2/11 at 11:12 AM

I've not seen the rear seats, are they a tad small?

===>The Roopod<=== is a reverse trike, uses the kubota from an aixam, water cooled and CVT



I'm stripping my engine at the moment and i'm trying to work out what engine & transmission arrangement to go for:



Trying to save weight so car gearbox is out and rear wheel drive won't need 2 driveshafts, trying to be as efficient as possible so shaft driven is out due to transmission loses and CVT is out. RWD with chain driven gearbox and wheel seems simplist, lightest and most efficient. or am I massively wrong?

Simon - 20/2/11 at 02:49 PM

Ben,

Have a look at the Ultima gearboxes from the usa. Quite cheap. Isn't Flak using one.

I've seen those on quite a few diesel bikes, they look good but £250 before shipping & taxes is a bit too much

I've seen those on quite a few diesel bikes, they look good but $400 for a second hand one before shipping and taxes and it's too much $$$


Have you seen this thread, Simon? Great read from start to finish This chap has used a big 70's generator engine, about the same output as mine but weighs in at 125kg (about 45kg more than my lombardini), the flywheel alone weighed 35kg before it was lightened. I'm thinking of lightening my flywheel, I've not had chance to weigh it yet but I think it weighs at least 20kg.
