someone needs to learn basic turbo fundamentals

 

I wouldn't want to be near the car when it is running that is for sure.

 

I'm at a loss for words.

 

Oh snappp!!! That's one of the funniest things ever!!

 

Is he serious??? wth!!! got me laughing...

 

Actually when I saw a turbo for the first time on a vehicle, I had no idea what is was and actually I thought it just recirculated the exhaust like this guy's idea until my father explained to me exactly how it worked. Around that same time in my youthful years, I actually thought (when I first heard the word) that supercharger was like powerful battery of some kind that made a huge spark.

 

To be serious here for a minute, the main difference between the two is that superchargers are belt-driven and run continously, so there is no lag in response, the power is immediate, and, unfortunately, the heat build-up is continuous too. Turbos are exhaust-driven by an impeller/compressor in a shaft, only cut in under engine load and greater exhaust flow, have an inherant lag in power and RPM buildup, operate at much higher temperatures (though some are water-cooled), operate only on demand, and usually have a wastegate, or bleed-off device, to prevent overboost. That's why special oils are sometimes required.

 

Lexmex was talking about his youthful days when he was young and don't know anything about turbo or supercharger with a sense of humor. Just like when people say thing like muffler bearing or turn signal fluid.

 

Yeah, but the oxygen tank required to feed such a closed system . . .

Somewhere in the back of my mind I recall an enterprising inventor taking a V8 block and grinding a special camshaft to allow the engine to run on the front six cylinders while the rear two provided light pressure to the induction system. I think it was perhaps invented in Europe for racing applications where cost was no object, but it is at this point my memory starts sucking air.

I know this technology is used in gas compressors, where power cylinders and compression cylinders share a common block. They are routinely used in gas pipeline and compression applications, but using it as an integral supercharger - even with oversized compression cylinders - was a special application of a known technolgy.

It sounds pretty crazy, but could be plausible. Since those two "supercharger" cylinders produced pressure on every stroke, rather than alternate-stroke firing pattern of a 4-cycle engine, the efficiency wasn't as bad as you might think. It was rather like a V6 driving an integral V2 air compressor that fed the intake manifold - probably through pressurized carburetors.

I think this was a product of mid-thirties engineering, but I can't recall enough detail to do a reasonable Google search on it. Anyone else hear of something like this? I know it was ultimately unsuccessful, but remained an engineering oddity.

 

I just heard this from someone but don't know if it has any truth to it...aren't porsche's turbos run this way, or partially fed through exhaust gases?

 

Too bad it is already done, it's called the EGR(Exhaust Gas Recirculation). I'm fairly sure almost every car has it these day, it pumps some exhaust back into the cylinders, resulting in a lower combustion temp. and less emissions, more burned fuel, etc...

 

This is practically useless. What a turbo does is use the exhaust gas to force AIR back into the cylinder, not combusted exhaust gas which would be undesirable. (unless you're trying to reduce NOX emissions like in a Diesel using Cool EGR etc.)

 

 

There is now a:

When you click the link now. I guess the mods there didn't want anymore shame on their forums...or too many people are joining up to tell that guy hes either famous, an idiot, or both!
