I'm getting 6km/liter in Bangkok using 91 benzene and its killing me. Anyone have experience converting a Volvo with B230 fuel-injected engine to LPG or CNG?

time for you to swap that motor out! I know that some of those B230 are fuel injected in some years while some arent.

6km/l in BKK sounds pretty good to me, for an old Volvo.

Actually even for a Volvo 6km to the liter is poor economy.

I have a Volvo 245 with the electronic fuel injection (engine model B230F)and I'm getting closer to 8km/l (on petrol).

Not sure which exact engine you have, there's 2 injection versions, one is the K-jetronic injection (mechanical, difficult to get to work properly), another is the Bosch LH 2.2 jetronic (entirely electronic, with lambda sensor).

On both systems there's quite a few things to go wrong resulting in high fuel consumption. The enrichment valve for cold starts might not close properly for example!

The Volvo engine is easily converted to LPG, both the cheap conventional system and the electronically injected one.

I get exactly 7 km/liter LPG on my car, currently working out to less then 1.5 Baht/km.

At your petrol consumption you're closer to 6 Baht/km, so LPG can save you some serious cash here!

My engine has the Bosch injection system. I get 10-11 km/liter on the highway, which isn't too bad, but its the stuck-in-traffic mileage. Can you give me any information on the cost of an LPG conversion and the difference (pros/cons) between "the cheap conventional system and the electronically injected one"? Any recommendation for a garage to do the conversion?

Thanks for your assistance.

The cheap installation between 15,000 and 20,000 Baht.

The expensive installation around 35,000 Baht.

Advantages of the more expensive installation:

* Computer will start the engine on petrol, and after a minute or so switch to LPG. This means that your petrol injection will stay in top shape. Never running on petrol would dry out your petrol system (fuel pump, injectors etc), leaving residue rendering the system inoperable! Which would mean you would be stuck if running out of LPG...

* Injection systems do not need the venturi ring in the air intake. This ring will reduce the amount of air which can be fed to the engine, regardless of whether you are running on LPG or petrol. Resulting in less power when running on petrol after the conversion. With the injection system, your petrol operation remains untouched!

* Due to the four injectors, LPG can be metered/injected better in each cylinder, resulting in better power and smoother running throughout the RPM range compared to the cheap system, end result is better economy.

If you are in Bangkok try engineer gas. We have had two cars converted to LPG there and we are very happy.

They have a website engineergas.com

hi, a friend of mine does the conversion for VOLVO cars. He is using fuel injection 5/6 cylinder kit, AC. the savings are great for LPG system. and also he can fit you with A 60 L toroidal tank. try contacting him on 089 0535457.
