um...that’s not what secondary air pumps do. They pump fresh air into the exhaust stream to allow any unburned hydrocarbons to have something to burn with in the catalytic converter, as well as supplying oxygen to convert carbon monoxide into carbon dioxide. They also assist the catalytic converter in coming up to…

Awesome video!

EGR only helps part-throttle efficiency on gasoline engines, which restrict air, to restrict nitrogen oxide formation.

It’s an absolute lose-lose for Volkswagen. We now know they are not capable of manufacturing vehicles that offer the stated emissions, performance, and fuel economy levels without cheating. So if they recall the cars to bring their emissions levels back up to what they should be, this will affect either performance or…

Am I the only one that found it strange that the VW 2.0 TDI was meeting US emission regs without urea injection until this model year?

The Oldsmobile diesel was the victim of several issues caused by GM bean counters. The original engine was reliable and expensive. Same as most diesel engines today. GM knew nobody would pay the incredibly high cost for the engine and started removing what they considered non essential components. The results should…

GM has a monopoly on that, it’s interesting they let VW into the fold this time.

Hey Mazda, I’m not saying it’s the perfect time to bring the SKYACTIV-D over here, but it’s the perfect time to bring the SKYACTIV-D over here.

Directly on the EPA letter

Nothing, but people like to type up mindless comments “cue this...”, “in 3...2...1...” etc etc etc....

What does this have to do with GM? Are they cheating too?

They wont break them, but they might only work intermittently from now on and only when you don’t want them to.

Interesting, I recently had a reflash on my 2011 Jetta sportwagen TDI because of some emissions issue. I wonder if VW saw the storm coming and started to try and get ahead of it...or if its completely unrelated. In any case, the “fix” they come up with is only going to shorten the life of the emissions systems, lower…

So this GM thing is pretty much as I explained it and caught grief here on it quite some time ago. Without the public having experience with engineering change notices, field failures, field service issues, and so on it is easy for various people to play things up into a vast evil conspiracy when really all it comes…

those people are no longer at the top, in case you’ve forgotten that the bankruptcy swept away some people. and when the ignition switch problems came to light, a bunch of other people were let go. If you think the current management should still be executed or something, at least be honest enough to say you’re just…

And the sound out the other end...

Youtube screwed me here... I filmed it horizontal and when it uploaded it came out vertical... some sort of iPhone debauchery...
Anyway, this was the first time I started it up...

I don’t think the water itself is physically pushing the tractor back, I think it likely was penetrating the cab (or maybe not) and the driver of the tractor reversed due to being blinded. The water would blast straight through the cab of the tractor before it would push backwards a tractor driving forwards.

It looks to me as if the armored vehicle was playing chicken and then manually backed off just in front of the tractor. Better to keep the paint job shiny and deploy the water cannon then sumo wrestle.

I don’t think you know what communism or socialism actually mean. Sanders is, truly, party to neither of those ideas in full. Further, what does the qualifier “boring” have to do with the noun “liar?” Would you rather an exciting or entertaining liar who wages a global war and robs its constituency blind?
