"gas version" of CRDi

[badkuk]

i heard from my uncle that a gas version of the CRDi had been developed. i have to admit i'm a bit skeptical -- i mean, iba ang mode of operation ng diesel and gas engine, di ba?

[jim]

Baka hindi na CRDi yung kundi CRGas hehehehehe

[nugundam93]

alam ko meron talagang iba na they inject fuel directly into the combustion chamber instead of dun sa intake tract, yan ba yun?

[niky]

FSi yun... Fuel Straight or Fuel Stratified Injection. Audi has it in lean-burn (stratified) mode in Europe, and in normal burn (straight) in the US. This is because the lean-burn mode produces too much emissions currently to pass US standards.

Mazda has direct injection on the Mazdaspeed 6 2.3 Turbo, too.

how about mitsu's GDI engines....

[niky]

Mukhang di nila tinuloy... strange, as they were quite advanced for their time.

I remember one Lancer owner trying to swap to GDi... ang hirap! Daming electronics, etcetera. Even the radiator fan was special!

[pajerokid]

Maybe nga he was referring to GDI. Late 90's pa lang meron nang 3.5L GDi V6 for the Paj.

alam ko nga for lancer 1.6 gdi, ung pajero io's have gdi's on them. mahirap nga sa swapping yan kung sandamukal ang electronics, magkulang lang ng sensors, malaking prob (what i learned sa liteace ko, grabe water level sensor lang for the radiator rervior di gumana/ nagloko, lagi ako ino-over heat, kasi pilit isusuka ng radiator ang laman nya para mapuno ung resevior)

alam ko 1st ang mitsu gdi sa technology na yan...parang ngayon lang nila tinatransfer ang direct injection sa diesels nila..

[kiper]

turbo din ung engine?

edi lakas sa gas nun pag petrol engine?

or.. ung pag inject lang ng gas ang binago?

[alwayz_yummy]

ang alam ko for gasolines, ung how the fuel is injected lang pinapalitan....pero meron din may turbo: alam ko is JDM pajero io 1.8L gdi-turbo...

[orly_andico]

have seen a few pajero's nga with the GDI engine.
i think VW also has it, and some outlanders (?)

it's just a swankier way of injecting the fuel, using much higher pressures (1000's of psi) rather than the tens of psi of our humble fuel pump. The result is the fuel is more finely dispersed, so it burns better and you can use less of it.

Mercedes recently released a new direct injection engine, its called CGI(Stratified-Charged Gasoline Injection).
The first model to use the 292hp 3.5 liter CGI V6 engine will be the CSL350 CGI.
