I can recommend the Bigas system my '97Disco ES has fitted, starts on Petrol
and the cuts over to gas when the engine temp reaches your chosen temp and
in our case when rpm is 1600 (i.e. on acceleration). You don't notice the
change over. The cockpit has a small switch with a push button, normally no
need to touch this. It also houses the display of led's for the lpg level
and shows either petrol or gas as the running fuel.
If you run out it beeps, you press it to silence it and automatically you
are on petrol. Refil and press button and once rpm and temp is as set then
you go to gas. Temp and RPM can be set by the installer. The system is an
injection system i it's self so can be mapped accordingly on a rolling road
for peak efficency. If for any reason you want to run on petrol then on
epress of the button and you are sorted, no cahnce in engine note or power
that I've noticed unless towing a very large caravan up hill or doing some
very scary overtakes.
On one overtake in France the system automatically jumped to Petrol due to
the RPM being so high, This has been addressed since as I was trying to
dodge arouund a cyclist at the time and the "bleep bleep" as it changed over
was rather startling given the engine kicked down to around 3500 to 4000
rpm. A quick tinkle on the computer when we got home (by the local LPG
place) sorted this so it won't happen again.
Also the engine will run when the system is down. In our case a short circut
due to the + from the coil dropping across the RPM wire. We had overtaken
several trucks and the wind bufet had dislodged a wire which I think I must
have loosened during my pre holiday oil change (ht lead disconnected to get
the oil around the engine before firing up).
Other setups allow you to run immediately from gas but if you live anywhere
cold then I would not recommend these as the tickovercan be lumpy until it's
Just my 2p worth. I'm in the UK. Bigas are based in Itally.
Only downside to the Bigas system is that you need 2 vaporisors as they
couldn't get one to run right (yet others can!) and the injectors can be a
bitch to set up again if you give them the annual flush through with carb
not a clue about prices, ours was fitted by the previous keeper who also
happened to be an LPG installer.
