Hello.

The car is about to be converted to lpg with prins vsi II system.

Anyone tried it or have it?

What is your opinion?

As I commented before:

The 1.0 ECOboost is not particularly the best choice to convert to LPG.
 

The 1.0 ECOboost is known to run quite hot (considerably hotter than other engine types). The internal combustion temperature is already pretty high on petrol and will even be higher on LPG because LPG burns considerable hotter than petrol. The cooling system (which is already a point of concern on this engine) will be put under even more stress to cope with the increased internal combustion temperature.

The solid valve tappets are another concern. Solid valve tappets will not compensate for valve/valve seat wear that is quite common on LPG converted engines that were not designed for LPG. To prevent premature valve/valve seat damage it is highly recommended to check the valve clearance periodically (which is quite a lot of work). If the valve clearance is out of tolerance it needs to be corrected which in case of a 1.0 ECOboost basically means that the wetbelt needs to be removed/replaced and the camshafts needs to be removed.

Considering the installation costs and increased maintenance costs in my opinion an LPG conversion is only profitable on very high annual mileages.

When running on LPG you should be prepared to check (and if necessary correct) the valve lash adjustment. The cylinder head of the 1.0 ECOboost is not designed for LPG. It does not have hardened valve seats. I personally expect the valve seats to be worn within 60.000 KM. 

Also be prepared for premature failure of the cam driven high pressure fuel (Petrol) pump and fuel injectors. When running on LPG the high pressure fuel pump will be building pressure for an extended period with only a limited fuel flow. The pump is not designed for this and will fail prematurely. When running on LPG the nozzles of the fuel injectors will suffer excessive wear caused by the increased temperature inside the combustion chamber. Be prepared to replace the fuel injectors approximately every 30.000 KM.

Another major point of concern is the fact that acid is formed when LPG is burned. Engines that are running on LPG suffer from increased acid inside the engine oil. Since the increased acid inside the engine oil directly affects the wetbelts it can potentially result in premature wetbelt failure. The only thing to prevent this is changing the oil more often.


When taken the installation costs and drastically increased maintenance costs into account an LPG conversion on a 1.0 ECOboost will never be profitable in most European countries. 

So you say that it will cause severe damages/issues on the engine.

The system icludes and uses a minor syster valve care. It injects a liquid that protects the valves.

It also uses 5% petrol.

In my opinion converting the 1.0 ECOboost is not the best idea. I personally would never increase the combustion temperature on an engine that is already running hot on Petrol.

Valve protection liquid injection systems can reduce excessive valve wear but will generally not stop it. When using such a system it is highly recommed to select a system that injects an equal amount of liquid in each cylinder. Avoid the systems that only inject the liquid at a single point inside the intake manifold. 

 

In my opinion there is a huge risk that the savings on fuel will be overshadowed by the increased maintenance costs. Since there are very little user experiences of a 1.0 ECOboost engine running on LPG it is basically a big gamble.

What do you mean?

To be injected 50% lpg 50% petroil?

That system also uses Kehin injectors (same kind as petroil's injectors).

 

I have experience of LPG, but, on a Mercedes C240. The car engine was still running strong after 160,000 miles when I sold it.(LPG was installed when new) There was no better feeling of smugness heading to the till in the local garage having filled the large tank up with a fuel costing (at the time) 40p/liter! I know it was a fairly common conversion on the Merc engine, and certainly made the car very cheap to run. But the advice on your 1.0 Focus does seem to have some food for thought...

Also on a lpg converted (brc s24) fiesta 2007 1.3 with hydraulic valves there is not a problem. Long trips,heavily loaded on high speeds and no issues.

But focus 1.0 is another thing. Especially since it is tuned/remaped.

Why?If you had a V8 OR large 6 cylinder,I could see the sense in it.We have dedicated LPG vehicles in Australia,I owned two @ one stage.But for a small car of that capacity, forget it.The cylinder will either go in the boot & take up nearly half the space,or alternatively under the car.Installation costs buys a lot of fuel.

Because fuel consumption is about 9,4/ 100km (a lot). Prices are about 1.8-2.0 euros per litre (very expensive) and the car is needed almost every day (many km per day). Also our economical sitouation is not as other europeans.

The lpg tank will be where the spare wheel is originally.

I just can not see any sense in it economically.You are getting 9.4/100 that is quite high.You should be in the very low 6/100 or very high 5s.I would look @ getting your system checked on the vehicle.I am constantly getting around 6.2 - 6.3.Our fuel is also getting expensive @ around an average of $2 per litre.No way I would even contemplate swapping to LPG.So,you lose your spare tyre(because that is what happens in a lot of cases,& is replaced by a ‘goo’ kit.)Think of what you are going to outlay for the conversion,against how much petrol you can purchase.

Here many cars (perhaps more than 10 per cent) are lpg converted. On fiesta it is about 35-40% money save since it was converted on 2014.

Ford Australia use to manufacture LPG dedicated Ford Falcons,I owned two,but gas is now getting expensive,& companies are now pulling them out of their petrol stations.Maybe look @ a good pre owned Toyota Hybrid.All of our Taxis use to run on LPG,now it is all a Hybrid fleet.

Maybe 9.4/100 because it's been "tuned/remapped"?????

So prices are getting higher also there.

Before tuning/remaping it was about 8,4.

Of course,it’s high everywhere.The price of a barrel of crude is around $96 a barrel,versus our dollar against the USD.Even in the US it is getting expensive.Russia/Ukraine crisis is not helping & the Arabs in the Middle East as well.

Way to high.

I have to go up to Sydney tomorrow,prices are all over the place.Lowest I have seen is around $1.96.9 & the highest is in the city @ $2.22.9 in Double bay(right on the harbour we’re I stay).Trust me,you are not alone in regards to fuel prices.

I dont know about the prices there. But they seem expensive.

That is why lpg convertion is usual here.

Other focus consumption are about 8-9.

So did anyone had or tried a lpg system on focus 1.0?

Especially prins vsi 2?

I'm a gamblin' man - I'm betting you that the answer is........ NO!

What lpg system did the mercedes had?

Nice. I suppose it is a British system.

Ford Australia had without adoubt the best LPG system in the world when it was developed,then released in 2011. Very,very advanced.A fantastic system.The engine would prime itself once the door was unlocked.It made very big kilowatts @ around 210kw & 409nm.The engine was a V8 ‘killer’.I use to own a Ford Falcon XR6 ‘Ecolpi’ (Gas)ute(pickup) the thing was a rocket ship.The engines had a code name of ‘Barra’,without a doubt one of the best straight sixes out there. Very,very strong bottom end.Major HP could be made out of them.LPG was cheap then,but is not that cheap anymore.It really is not that economical to swap to gas.There we’re also subsidy’s @ the time when you purchased a LPG vehicle from new.
