That’s interesting. I never knew that was possible. My father got heavily into biodiesel, but that turned into a mess, so I’m not overly excited to try something like that, but my ex-manager had a natural gas injection set-up on his Duramax and when I borrowed it to pick up a Volvo S60 (10 hour drive) it got tad over 30mpg towing it though the mountains (end destination was higher then the start). Anyways I was very impressed, so NGI is something I would love to mess around with.

Right. I was assuming that it wouldn’t get enough vapor to start before I watched that video I shared.


I would be interested in this too. I would think you could adjust the A/F ratio by changing up the pipes that agitate the fuel

Just don’t put any weird shit in a common rail diesel. Just because a good OL injection diesel can run on snake oil, doesn’t mean a new one can without destroying the fuel system.

A 4 cilinder doesnt sound as nice as a V6 or Straight 6.
But in certain cases a 4 cilinder does pull better,
if you compair two engines with similar cc´s.


#1226

The undying truth, and reason I quit mechanics.


#1227

That’s true, but how often do you see a 2.0L v6?

There’s a reason for that. Tiny engines aren’t as volumetrically efficient as larger engines, from my understanding.


#1228

Nowdays not much anymore.
But there have been plenty in the past.


#1229

Eh, I suppose.


#1230

BMW 320i, 520i.
Mazda MX3 1.8 V6 and i think this was also in the Xedos.
Nissan had a 2.0V6 and a RB20DET straight 6.
Kia has one in the magentis.
Lexus IS200

There were really plenty, but nowdays you dont really see 2.0 6 cilinder engines anymore.


#1231

From what I understand, smaller pistons can equal better efficiency.
My Volvo wagon is a 240hp 2.3L 5 cylinder, and it gets 25mpg (used to be 28) in a 3,500lb box.


#1232

Unfortunately that looks like a Cadillac engine. I’m disappointed with GM. That’s probably the dumbest thing I’ve seen yet.


#1233

Pretty sure it’s a Northstar engine


#1234

The FWD DOHC V8 leads me to agree.


#1235

Yeah well my dad has owned a BMW 320i E36 in the past.
And yeah the sound of that straight 6 is nice, especially with a cai.
But its just very lazy, doesnt really pull anything.
a 6 cilinder is nice wenn it is 2.5litres or better i guess.

Allthough a BMW325i doesnt really do much better either.


#1236

Definitely depends. Chevy made a garbage 2.8L V6, but Mazda made that beautiful 1.8L V6 you already mentioned.


#1237

Yeah the 3.2JTS engines that GM had for Alfa romeo was also a pile of shit.
Fiat had abandoned the production of the Busso V6, the biggest mistake yet.
Because the Busso V6 probablly was one of the nicest V6 engines ever made.


#1238

Interesting. I didn’t no GM was in bed with Alfa Romeo.


I recently watched a video one of those cars.


Extremely cool car, but I really don’t like the way it sounds. /opinion

Smaller pistons mean there’s a lower reciprocating mass, which means a given displacement can hit higher RPMs. That’s why V12s in Ferraris and whatnot can rev so high.

There’s a larger total mass (crankshaft primarially) in the system, so it takes more energy to move it. Means it’s not entirely as efficient.

There’s your problem. It’s an E36. Those things never made much power.


#1240

Yeah well the E46 didnt either really.
And after the they became 4 cilinders i guess.


#1241

Eh, I’ve never liked BMW for the power to price ratio.

A 3 series isn’t fast.
