OK a bottle of Red and or.. if

Being very frugal, with jewish ancestery , and having long pockets and short hands- in assiciation with PRINS lpg systems- are starting a project to run my HPDI's on LPG. It is very possible but am missing one parameter-.

Anybody know the opening time of an injector in milliseconds of a 250 hpdi at 3000 rpms? and idle at 600?. Yamaha dont want to know- . Cant even find out who makes the injectors.

If the project is successful,a large LPG distributor in Belgium has promised to put a LPG barge in Nieuwport free of charge.

Prins have succesffuly converted 4T Evinrudes going to 200 HP. The company doing this is Antwerp based. It all depends on the soft- but the above information is the go or no- go

Have you tried running on 50/50 petrol/kero or even thought about it?

That a good idea, but a 50/50seems high.With LPG will loose about 12% power. Would it fire on a 50/50 split? Try it on YOURS first????

In some countries they actually sell petrol mixed with 60% kero 40% petrol and people often don't notice - mind you it is places like India!!!

If it wasn't for the fact I am going to run commercially and will be able to get petrol for 32p a litre I would!!!

Obviously you would start at a much lower rate - say 80/20 and work your way up - you may have missed it but Evinrude are now making multifuel Etecs that will run on neat kero.

Yup has been mentioned before. Also they used to start on petrol - switch to parrafin - then back to petrol again before switching off to flush through.

Maybe when I decide to re-engine with a 300 I will give it a go on the old one - as I have twin tanks it would be quite easy - wouldn't try it neat though!!!

Run commercially?? carrying what? Shrimps?? have I missed a post" dont you need to register your boat ?. Mine is under a SSR registration - I use to be able to claw back the duty-and probaly still could if I was making more use of the boat as its intended purpose. The other problem is that in Dover they hate you if you start filling up with jerricans- in fact the Harbour master threw me out as " a risk to the public".....

Going down the LPG route- as if it blows , will probaly take the whole port
of Dover with it. That 's not such a bad idea?????

Thanks . But I am not running a bloody tractor!!!!!!!!!!!!. The yam 250 HPDI 2t is state of the art, software version 99999.0000, developed over the years by very talented peole, and operated by an --- idiot. These motors are
"delicate' themselves as regards fuel- and anything below 90 octane - probably will cause damage.I am not prepared to throw away 12000 euros worth of enginering wonder. LPG on the other hand can only do "good" to the
engine- for one thing dramatically reduce deposits.

I would nominate Codders to run a test using HIS engine- as he was the one who suggested this in the first place.
