Originally posted by VERTiG0 True as well, but the lifespan of these filters and catalytic converters can be increased to the life of one used on a gasoline engine through the addition of Mercedes' AdBlue tech, which is just carbamide injection into the exhaust gasses straight from the engine before it hits anywhere else, as in that diagram I posted earlier. BLUETEC will be the clean diesel savior!

This is straight out scary. I had no idea they were pumping urea into exhaust to reduce NOx emissions. I can tell you that if this technology were to become widespread it could potentially be one of the biggest scams ever.

Why?

1. They would potentially have to implement Adblue filling stations everywhere diesel is sold.

2. There would be a cost to have Adblue, no one would manufacture and distribute it for free. These costs would eventually be passed down to consumers like you and me.

3. If the vehicle using Adblue runs out of it, the user could continue driving along anyway since it is not necessary for engine operation.

4. Manufacturing urea is not a clean process. During the reaction itself ammonia and particulate matter are produced, which potentially adds to air polution is it isn't passed through a scrubber. Further, there is an energy cost - the manufacturing plant would have to either produce it's own energy, via burning natural gas or purchase it from an electricity provider (which would likely come from coal fired plants anyway...).

When you look at the end result of this you could reduce the harmfull emissions produced by all the diesel engines out there. However, you will increase harmfull emissions through the production of urea and the energy needed to produce it. I would really want to see a study that looks and the net reduction or gain in pollution as a result of this process before deciding whether or not it is anything more than just a cash grab.

this would do nothing but make driving on the highway a COMPLETE nightmare, which it already is if you are heading towards Ottawa, but at least eventually the trucks get passed each other. having 2 buckin at 105 would cause accidents from people tyring to pass on the shoulder!

On another note, the US has banned urea as an additive for emissions control.

i disagree. governed trucks will fall in line with each other like they already do. Trucks are actually pretty good at keeping the passing lane open.

All it takes is a handfull to screw it up and I ALWAYS run into them in my travels to Ottawa.

Originally posted by Jayx1 another stupid law. Many truck companies enforce 55 mph limits on their trucks to save fuel and mileage costs. However they enforce this by GPS, not governers. Why? Because they still allow for the trucker to speed up when necissary to avoid a hazardous situation.

Why would a truck need to go faster than 105 kph to avoid a hazardous situation?

it happens all the time. sometimes a short temporary burst of speed or just even some horsepower at the right time can avoid all sorts of dangerous situations.

A quick boost of speed at 105kmh+ in an 11-ton truck is an oxymoron!

youd be surprised!

youd be surprised how much of a difference it makes. You see the situation happening , could get out of it so easily but u hit the gas and nothing happens......even worse its a downhill and the engine retarder kicks in and u slow down while everyone else is speeding up.

How does going faster help you get out of a potential accident situation? Usually people slow down to avoid accidents. Yes, sometimes you might need a rapid burst of acceleration, but if you are going 105 kph already in an 11-ton truck but how much faster do you need to go to avoid an accident? Accelerating to speeds over 105 kph won't help you avoid accidents. Just slow down, or move onto the shoulder and slow down.

I think governing truck speeds is a good idea, there will be less pressure on truck drivers to drive quickly as their speeds will be limited. This will reduce accidents and fuel costs, but also make transportation times a bit longer. Worthwhile trade off I think.
