Na nežinau... Reiktų smulkiai gilintis kaip yra dėl jų. Vis tik pas abu tiesioginis įpurškimas. Alfaowner'y rašo žmogus, kad tas dujas kaip ir įmontuot galima, bet dėl perkaitimo nutraukta gamyba: only one giving me a problems was the 2.2JTS engine (sometimes problem with overheating). find out that afterwards BRC stopped offering the equipment for JTS engines. Similar with the Landi Renzo, Viale, Prince.
It seams that JTS engines have few minor problems with gas:
since having WCOC (water cooled oil cooler) if mostly running on LPG, oil does not contribute enough in cooling engine and overheat happens
LPG has bigger energy value than petrol, therefore by burning is developing more heat
JTS engines run on so called "lean burn" principle, which means higher temps (even with the petrol) then the normal TSs and other engines
am not sure if the fuel is used in engine head for cooling valve seats (like on, for example, Ford Z engines), any clue?
All this indicates that something special with the extra cooling has to be done, if we want to make JTS running on LPG."
Taip pat: "My dealership in Berlin told me that they still offer BRC system with pre-warning that there are some troubles to expect (over-heating) and that they do not recommend it."
Tik nelabai įsisiskaičiau,ar apie minimas BRC kalbama kaip standartines dujų įrangas su dujų kompu ar grynai tas, kurios tinka tiesioginiam įpurškimui. "Company Viale (Netherlands) is having the solution to similar lean burn
direct petrol injection engines from VW group (TSFI), but they
still do not have dedicated solution for the JTS (unfortunately, JTS itself is not produced any more and ARs are definitly not manufactured as bloody VWs, so not great business case). But it seams that they have sorted out the problems."
