I think it's a 2.1 or 2.2L Mazda's using.Yup, with the exception of the 2.8 that GM uses in the Colorado/canyon. Not sure what size Mazda is using.
Does the 1.4TSI have the "feature" like some Kia and Ford DI motors I've observed that when you punch if after driving gently for a while, a huge cloud of brown gunk blows out the exhaust?...
And here's the emission control label...
I figure I should drop this here (Yes, this is oilhammer's diesel Vanangon):Y'all haven't experienced anything until you've driven a diesel Vanagon (48hp)
The bugaboo with gasoline engines is controlling the temperature of everything post-combustion. Pistons, exhaust valves, catalysts. When running at stoichiometric (necessary for 3-way catalysts to function), exhaust temperature is very close to the highest it can be. The easy way to control it is to go rich under heavy load, and it's pretty obvious that the Ford Ecoboost engines do that. Even normally-aspirated engines can require meltdown protection under load, but nowadays it's usually well above what's seen in normal driving conditions, and frequently the engine controls contain an internal mathematical model, and only go into rich protection mode after a period of time at high load, i.e. not very often. Turbo engines can require rich protection mode much more frequently ... in the case of a friend's Ford Explorer Ecoboost, any time it has a trailer in tow. The exhaust pipe is very black inside.Does the 1.4TSI have the "feature" like some Kia and Ford DI motors I've observed that when you punch if after driving gently for a while, a huge cloud of brown gunk blows out the exhaust?
I never observed this on our room mate's 2.0 TSI Tiguan.
I drove my '93 300D to work today and was thinking as it was quietly cruising up the freeway what a great trip car this would be, and how much more peace of mind I'd have driving it than a newer Mercedes, even a diesel, despite my car having almost 200K on it. I feel the same way driving my ALH on a road trip versus the GSW or BMW.I do not feel there is ANY engine sold today that will last as long as some previous designs. And this is from any manufacturer.
Under the intake, bolted to the top of the block in the lifter valley, is a valve body with a bunch of solenoids and passages running all over. These gunk up and quit working, causing lifter/cam/valve/piston and sometimes complete engine failure. The older engines didn't have this, so it wasn't even there to break.What's the issue with the cylinder deactivation?
May be right.Whatever weirdness is going on over at the EPA, I think this initiative is for real. The clock is ticking on the availability of delete tunes for street driven tdi's, imo.
While California is relatively lenient to the passenger car/light truck crowd, they've been horrible for commercial truck and bus owners.Speaking of "the truck crowd", while the small penis syndrome folks are certainly well represented within that group, there are also lots of commercial vehicles that the company just needs the equipment to be reliable and durable, and better fuel economy certainly helps. One of our commercial accounts had repeated issues with their F550 with the 6.4L diesel they finally gave up and took it somewhere in Illinois and had a "false" DPF/catalyst installed. It looks just like the original, just no innards. And of course the software was altered. I noticed it when they brought it in for state inspection (we do not service this particular truck) and it had sooty tailpipes and clearly smelled like a non-DPF non-catalyst diesel. But it has not broken down since, runs better, and uses less fuel. So....
And they use it for its intended purpose. Moving VERY heavy loads (rooftop A/C units) and towing their scissor lift and other equipment. It is a small business, and this is the only truck of its type they have. None of the rest of their vehicles (E-vans, and now Transits (which are already broken)...) can do what this beast stake bed truck can do. They depend on it. THEIR customers depend on it. This truck was so unreliable before the owner was actually looking for a 7.3L truck to refurbish for a little birdie told him about fixing the 6.4L truck permanently.
True, in fact, no areas in the USA exceed the NO2 NAAQS, or are even close to the NAAQS NO2 limit (53 ppb)....We've NEVER had any NOx problems here....
