Maximum speed 105 Km/H on old used trucks?

http://www.ontla.on.ca/documents/Bi...ssion2/b115.pdf

check that out. I can't believe this. From my interpretation they are trying to enforce that all vehicles made after 1995, when sold as a used vehicle, have a device that ensures that they cannot be driven above 105 Km/H.

Wow. Passed second reading... looks like it will be enacted. Who is this Ms Scott?

for vehicles exceeding 11,000 kgs i.e. Trucks


I fail to see how reducing truck speeds will Improve Air Quality. so know we can slow the trucks down on the hills, thus backing up the entire Highway and Increase car emissions..

You missed the most important part
S. 4(c) has a total gross weight of greater than 11,000kilograms.

This would pertain only to heavy commercial vehicles, perticularly Highway tractors. Most US jurisdictions have such legislation already and most large transport fleets have been doing this of their own accord for the past 15-20 years (fuel economy reasons).

Lower vehical speeds = lower engine speed, and lower fuel consumption/KM, therefore improved air quality.

ahhh yes, just scanned it, makes a bit more sense now.

The only significant increase to the air quality we'll ever see is if all diesel trucks are fitted with common-rail injection diesel engines with NOx filters that run on the new low-sulfur diesel.

As it stands now, the sulfur in the diesel fuel that is sold in North America works as a lubricant for these engines, and they are going to have some fun working around that.

Modern diesel tech is so much cleaner than gasoline, and it horrifies me that we aren't using it here. People hate diesels because of these trucks because those engines are smelly, dirty, and sound like a skeleton masturbating in a filing cabinet.

Result from paper towel pressed up against the exhaust of 2 running Mercedes E-Class cars, otherwise identical except for the fact that the black one is diesel and the silver one is gasoline. You can plainly see that with low-sulfur diesel fuel, proper filters and perhaps even urea-injection units installed in the engine (which we likely won't see, as it was a stop-gap measure in Europe), the diesel is immensely cleaner.




Here's what I'm pretty happy about, Mercedes' BLUETEC clean diesel tech. It'll be here soon.

OMG Cale...

So you have a fetish for cars....

Diesels man, diesels.

I would kill for a BMW 535d Touring.

The big problem is that as vehicle speed increases (linearly) the drag or frictional forces increase exponentially...

This only shows a reduction in particulate matter, or straight carbon emissions at idle, I would assume. I doubt when doing this test did they accelerate both engines. The majority of the particulate matter is emitted from a diesel engine when they are under load / accelerating (ever been behind a bus when it accelerates?). When running at idle they emit very small quantities.

Diesel engines are notorius for their high NOx production and the only way they can reduce this is by using reduction catalytic converters. The only problem is that their tendency to produce large amounts of particulate matter under load tends to reduce the life of the catalytic converters (due to clogging).

Newer diesel engine technology is definitely looking promising, but I would guess that we are many years away from retrofitting all heavy duty vehicle engines with this fancy new technology.

That's correct. Idle indeed, but it's still just to give you an idea of the difference between diesel and gas.

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!

It won't happen in heavy commercial vehicles here in North America for a long time, but passenger vehicles sporting this fancypants gear will be here in a year or two, now that we've got low-sulfur diesel coming here by mid '07.

Old german cars are the smelliest to drive behind of... especially Jettas and Golfs.

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.

105 km/h limiters are actually a detriment to safety. Lets hope this stupid law does NOT pass. Perhaps they should put more MTO officers out on the highway to enforce the speed limit if they really want to.

First trucks, then cars...if the government can get away with this, they will try to expand it... trust me on this.

Actually, most trucking companies use governers... normally set to 65 mph. GPS is used to track the movements of the fleet but it is no good for controling speed as it would require constant requests for locations... more requests equals more cost. Like I said earlier, most US jurisdictions already mandate goveners and most Ontario firms already use them as they are required to operate in those US jurisdictions that mandate them.

huh?

the gps system at my work is completely automatic and every vehichle shows where it is/what speed and logs everything automatically.

extremley cost effective and specific........ you can even type in .....steeles ave + 85 km/h and it will show u the five buses that hit that speed in the last month. (were governed at 109) which sucks sometimes when you get jammed and could use the extra power to get out of a situation. i agree that the governer does create a safety issue. But probley eliminates a lot more safety issue than it creates.

Really? You Go people have the best stuff. Most of the trucking companies I deal with need to make specific requests on each unit they are tracking when they want to determine location/speed. Perhaps, the trucking firms just cheap out or the larger required coverage area necessitates a different system.

unless it has changed then it was always the GPS that tracked where they were, how fast they were going, idling etc.

When i was travelling with my uncle 10 years ago this is how it was with schneider. They had a limit of 55 mph governed by the GPS system.

hahah we barely drive over 40 sometimes in our work trucks only cuz we like to take our time to get places..

I totally forgot about that. With the size of the front of a truck, that would be alot of drag.

But, do frictional forces increase in the same way, and would the play a large factor here? If the truck face was frictionless, would it still create drag?

Drag = friction. It is impossible to create a truck or should I say any object that moves through a medium with zero friction. Theoretically the only way you can move an object with zero friction is if you move it in a vacuum (the closet approximation being outer space).

int he 70s the US used the same arguements of fuel economy as justification to lower all interstate speed limits to 55 mph (88km/h). And Canada (ontario)followed suit lowering the speed limits from 75 MPH (122 km or so) on the 401 to the current 60 mph (100 Km/h). I use MPH because back then Canada used imperial measure like the US.

The US has sinced raised their speed limits back up and we have not.

70


regardless thou i see your point, but personally i think enough people get killed or injured every year to justify us going even faster. Alot of our highways are just in too bad of shape or not designed properly for a truck to be doing much over 110 km/h

quote:

I am guessing they did so because cars are more efficient today, BUT the average car now gets worse gas milage because the average car engine is so large today (SUVs). They should have left a lower limit, but then they would make the oil/car companies unhappy.

Keep them low, people in NA don't know how to handle fast cars or high speeds anyways.

I started with heavy commercial 6 years ago so I can't comment on 10 years back. Schneider is in fact the largest trucking fleet in the world, I'd expect they'd have amongst the best tracking system.

I know that the speed, locations, when the ignition is in what position, time idling, etc is all available but it normally must be requested and downloaded from the service provider (as most trucking companies outsource their tracking.... that could be a major difference there, Schneider would do the bulk of theirs in house).

Regardless, I can assure you, most fleets that operate internationally now use goveners. As Schneider is self insured I've never had opportunity to deal with them but most of the big fleets are governed.

Self insured would probably explain it then.
