Regulus

L.P.G. is injected, not petroleum or gasoline liquid. Hygroscopic is not the correct term I was looking for, but the fitter said something like that.

Thanks Starti. Separately alongside the 60L Diesel tank there is a 17L LPG tank. When the engine is at temp, the gas gets injected at a fairly low percentage. Roughly 17L gas per 120L diesel. Its makes a fat load of difference. Apparently the gas is Hygroscopic (???) and causes the large carbon chain of the diesel to elongate (???) and burn more efficiently. The LPG does not truly fire, it merely opens up the diesel for a more efficient burn. On topic, the wiring was checked to be in order but who really knows without fully checking every terminal! Also, the issue raises when either tank are at any level, full or low. Someone last night said maybe the fuel pump which has merit as usually the issue arises about 30 seconds after going over rough ground or fanging around car parks dodging old ladies.

Hi All, I have a 2000, 3ltr turbo diesel which has been converted to run on gas. The set up has been done by a company called E-gas in Perth, West Australia, and when the engine is warm, the system injects gas into the intake before the turbo. Makes a huge difference to power and efficiency. That's not why I am here. You see, if I were to go over uneven ground and the car rolls from left to right a few times, not very heavily, after a few moments I get the engine warning light and the idle can jump from 700 up to 1200 sporadically. It'll do that and sometimes stall, for about 30 seconds and then it disappears. Are there issues like this recorded before or do you think it may be an issue with the gas? Any help would be greatly appreciated. Regards, Matt
