LPG concrete

[jean63]

I just had my R25 GPLisée (291000kms) adjusted by the specialist on Clermont Fd (Chartoire) and here are the results

Super: the guy from the garage who is the only LPG specialist has fixed everything nickel.

1 - Essence : he set me idle at 950 RPM,

CO lu = 1,0; CO2 lu = 13,1; CO corrected = 1,2; HC = 288

2 - LPG : it has not replaced anything (filters, vapo-regulator, etc ...) despite the kms (291000kms including 150000kms LPG), but simply adjust the wealth and idle. it turns nickel in slow motion + super good acceleration!

CO lu = 1,0? ; CO2 lu = 12,7; CO corrected = 1,2? ; HC = 250

LPG values ​​are not safe (they did not record them and gave them to me from memory).

What is certain is that it was very fast.

Invoice = adjustment LPG: 25 euros HT
MO high tech (gasoline): 21 euros HT

TOTAL invoice = 56 euros including tax.

About the tank, I asked the question: a tank of 80 liters can not contain more than 64 liters (80% capacity); There is a pressure limiter since they mounted the new 2000 safety valve.
So for me it's normal.

Before I could put 72 liters!

1% of CO is still huge ....

I know more the current standards of head but 1% it seems very important ... especially LPG ...

[jean63]

Yes, me too it seems big, but I did not see the display on the device. it must be said that my system is not perfected, it is a "sucked".

Too bad, I would have liked to read on the measuring device, I thought he was going to call me, but they do not like that customers hang in the garage!

Here I found the mistake for the CO.

In fact it is 0,1 (he wrote by hand, it is not the print of the tester, eg the printer was down?).

Why 0,1: I just watched my last check of 15 / 09 / 2005 is marked 0,1.

I prefer like that.

[Christophe]

Yeah 0.1 is already bcp better ... even a little weak for slowing down ... Are you sure the device was reliable?

[jean63]

I can not tell you more for now, because I do not want to pay 15 euros (mini) to have a pollution report at another garage.

I found in my bills an old gasoline control I had done in 2000 (211000kms) CO: 0,3 in essence, just after setting in garage and printed by the camera, so I deduce that the 0,1 in essence is a little weak but not so far from the truth, for cons I do not have the value in LPG since it had not raised and gave me the same that in essence to get rid of the pb; he was already on another car.

The 0.1 technical control is not that bad (a bit low) unless it was running LPG when it went to control? Just leave the inter on GPL and he do not know!

We must not forget that it is an injection with electronic calculator renix and T ° water sensors, T ° air, depressions, rattling ... so fuel injection quite accurate, it is not a simple carburetor.

An idea

And if you made a section "comparative assessment pollution vehicles" or a similar title, in which each participant could come to give:

- vehicle type
- Mark
- gasoline or diesel or LPG or CNG
- engine power
- year
- catalyzed or not
- FAP or not ... etc
- Pollution report (Co, CO2, HC, NOx, etc.)

it would be interesting to see the values! Maybe we would discover weird things?

[abyssin3]

Jean63, I thought of a question "special LPG" that comes to mind: you would know if the exhaust gas at the same temperature for LPG than for gasoline? to the extent that they are not the same compounds one can ask the question, especially with a pantone.

It could also affect the efficiency +/- of the catalytic converter (Ex: + hot, therefore better catalysis = less polluting emissions)

[jean63]

I do not know how to answer your question about the exhaust temperature.

There is no catalytic converter on this vehicle (1989).
I especially do not intend to put a pantone reactor on this vehicle, it's complicated enough when we have a problem to find the cause. Non-specialized LPG mechanics still have a suspicious look at LPG as soon as they lift the hood, so imagine if they see an 2 "gas plant" .

me it's the same I must go to make it rule because of it she cal at the stop she is equipped factory and has 256m km
