Re: Flashlube

Dobry. Sorry for the late reply but I have to go away for business. I will answer you properly when I come back from my trip. I'll show you some experimental results from engine testing my researchers have done, and show you why the Carnot cycle is not really relevant. (but good for teaching with) I...

Re: Viella LPI system help

I am not familiar with this system, so I wont be much help. However to help the next person along can you answer these points: Was the car previously running well and it just happened? Is this a new conversion that has never worked properly? Can you confirm that the tank/fuel line solenoids are work...

Re: 'Dirty' gas strikes!.. or does it?

I use LPG from heavily frequented suppliers, 1.because it's handy & 2.if petrol and diesel pump quality is anything to go buy then generally an oft used tank and pump tends to have less plaque and build up than a little backwater place that pumps 10 gallons a day. That may be a consideration. Tank p...

Re: Flashlube

Dobry. Excellent technical posting. I agree with some of the things you have said on temperature, except the lower compression ratio (I think you meant raising CR - higher CR = higher theoretical gas temperature before combustion = higher temperature before blowdown). I do not agree with your conclu...

Re: Looking for wiring diagram

I think I am correct in saying that most Tartarini systems (in the UK) are dealer fitted, so it may be hard to find wiring diagrams in general circulation.

Re: Help ... (bmw 316i)

1. The big answer is that if there is not enough heat in the engine coolant then there will not be enough to vapourise the lpg properly, or at all, and so your car will stall and kangaroo for a while. This means you will run lean, and this is not good. The short answer is 'Live with it'. The environ...

Re: Poor quality insulation

I have nothing constructive to add, save to say that likely explains your very bad fuel consumption. A leaky MAP will throw the ECU's lookup tables out - with atmospheric P in the manifold the car will read it as if it's being pressure charged or the ECU may not cope at all and overfuel. My consider...

Re: Flashlube

You choose the metal of the head based on the likely cylinder pressure, the minimum allowable casting thickness, how thick the walls between galleries etc. will be, thermal expansion properties and cost. On some engines there are no seats as such - just a machined head. On some the insets are soft. ...

Re: Flashlube

The ability to run on unleaded petrol is not the issue. Softness of valve seat material and its interaction with the air/fuel mixture, combustion mixture and blowdown mixture is the issue. Oxides from these mixtures form on the seats that can* have a protective effect even in modern unleaded vehicle...

Re: Flashlube

In order of question marks: I don't know if you have one either. If your engine has a soft alloy head or soft valve seats then yes you should. If you can work an electric drill and a tap (of tap and die set fame, Aldi £14.99 for an okay one), then yes. They can be found for £45 + £3p&p on the well k...
