I get 3.9L (3,9 litros)
4-cyl/4-valve per cyl (quatro cilindros em linha, quatro válvulas por cilindro)
Maybe someone can translate better to the correct numbers.

A Cummins B3.9 is a 4-cylinder engine; it's a B5.9 (i.e. the one Dodge uses) minus two cylinders .
Back when I kept up with the B-series more, I was given to believe that most folks didn't care for the B3.9 in vehicles because of the excessive vibration; they may have added a counter-balance shaft to the engine since then.
Cummins also has an A-series 3.9 engine, that's a 6-cylinder. I understand that they were popular in UPS trucks for some time.

Actually, forced induction and CNG/LNG is a good combination, especially when dedicated. You need fairly high compression to extract all the energy out of CNG/LNG fuel.
And the 4.3 Chevy V6 is a fairly reliable motor, since it's 3/4 of a small-block 350 (at least in the geometry).
And to keep this diesel-related, I *THINK* I heard somewhere that at least one GM division had a diesel version of the motor (or one with similar displacement). Of course, it was a POS. A co-worker many years ago had a diesel Buick Century, if memory serves... sounded like a diesel, smelled like a diesel, couldn't get out of it's own way.
There's even an online "enthusiast" community for them.
(Strangely enough, upon reflection, the Olds diesel and the 6.0 share a few common problems and solutions, at least at first glance... (NO! Do NOT shoot me!!!) )

There was indeed a GM 4.3L V-6 diesel, but it was related to the Olds 350 diesel, not the Chevy 4.3L V-6. Except for only having about 90 h.p., it was actually a pretty good engine. By the time it came out in 1981, GM knew all the problems in the 350 diesel and engineered them out of the 4.3L V-6 diesel. It was made in both front wheel and rear wheel drive versions, and some even had aluminum heads. There was also a 4.3L V-8 Olds diesel that was used in the Cutlass Supreme for only a year or two in 1979 or so. It was as bad as the 350 diesel. I had hoped at the time that GM would offer the 4.3L V-6 diesel in the Chevy S-10, but it didn't happen (though a few S-10's were built with an Isuzu diesel). BTW- those UPS trucks ran good when we were through with them. The manifolds were similar to what was on the Typhoon and Syclone.

I kinda figured someone would not bother trying to re-invent the wheel.-blaine
