Subiect: Motoare Octavia 2 FSI

LPG-ul vine cu propriul computer control, deci nu cred sa aiba legatura cu ECU masinii.

da, corect, am vb deja cu cei de la BRC si astept un raspuns intr-o saptamana si ceva oficial daca macar o sa incerce pe seria mea de motor. Pe celelalte 3 au reusit cu succes. Ce ma roade e ca nu imi dau seama prin ce e diferita seria mea de celelalte 3 care sunt tot pe Octavii 2. Nu ma pricep la partea tehnica deloc (doh ) si nu stiu daca e diferenta de calculator de motor sau sunt si diferente interne in structura motorului

Si alt raspuns pescuit de pe Briskoda: " the fsi system needs the petrol to keep the injectors cool enough to run, which LPG will not do."

Si inca unul de pe audi sport forum: "Can you convert an FSI engine to LPG ? Answer is no (as of May 2006)
Do to the nature of the FSI injectors, an LPG conversion is not recommended. If your FSI engine is converted, you will end up spending ££££ on new injectors every 4-6k miles.
I was hoping to convert my C6 3.2FSI but now I'm left with no option.
Thought i'd let you know."

Si in continuare:

"The FSI and TSI engine are very particular cases, with BRC the FSI versions can be sucessfully converted to run using LPG by Arun Autogas.

There are several important reasons why normal sequential gas injection systems are not suitable. Initially, the petrol injector nozzles will clog, & overheat) if not used, while running on gas.

One needs a system that will dual-fuel both petrol and lpg simulaneously. So the system runs 75% lpg and 25% unleaded. Great saving are quickly realised.

Be aware that the set-up is vehicle specific and not easily achieved without thorough testing of emission, exhaust temperature and favourable power output. We don't want to blamed for damaging your engine. We will only install proven BRC Direct Injection systems. The costs is £1750 + vat for all the listed engine models. These lpg conversions come with 24 months parts warrantee, extrendable third party breakdown.

Cred ca nu ar fi rau sa ii contactezi pe BRC, uite ce spun aici:

"The specific engine code is essential as this excerpt explains "Your car's engine is a direct injection petrol thus it would be not suited for LPG conversion. Direct injection engine, relies on petrol to cool the petrol injectors in the combustion chamber but running on LPG, this will not be the case and can lead to petrol injector damage.
However, the 1AZ engine used for African market is non-direct injection, so if you change the head and the ECU, in theory you can run it on LPG no problem without any damage. However, it is not economically viable to do so as the cost of doing so will probably wipe away the savings you will make by running on LPG.
I run my Avensis on LPG. I bought this one with 3S-FE engine, which is a non-direct injection engine mainly because I had LPG conversion in mind. The later model which have the same engine as your's (1AZ-FSE) looked attractive in many ways but went for the early model because of this.
But, the 1.8 variants (1ZZ-FE) is not a direct injection engine so this can still be converted. So as the 1.6 variants (3ZZ-FE) but on 1.6 will be under powered running on LPG so 1.8 is preferred."

Poate au o explicatie pt care in cazul codului motor BLX nu au inca un LPG compatibil.

florin, da-mi si mie VIN-ul prin MP.

[florin]

BLX-ul meu cred ca la fel cu amestec saracit. daca asta e adevarat si restul nu sunt la fel, ce determina lucrul asta ? calculatorul sau sunt si diferente fizice in motor ?

[B e b e]

stiu ca la 1.6FSI poti sa ai o varianta (BLF-ul meu) la care i se zice ca merge cu amestec saracit. ..mai mult nu stiu.
