Emissions Test: Car vs. Truck vs. Leaf Blower

Thats not really news....

Could substitute most modern vehicles in that....

My goof in title...Fiat 500 used...the new "economy" car...

Fiat had lower CO2, as expected. It is hard to have both low CO2 and low NOx. CO2 is only a function of fuel burned and so engine size and power. There is no cat converter for CO2.

CO is carbon monoxide. It is not CO2. CO is from incomplete combustion. Of course CO2 will be higher on the raptor, but I don't think CO2 is considered a smog causing element. I may be mistaken there.

The reason the fiat looks just as bad as the raptor is that the emissions are measured in PPM (parts per million). The overall volume on the Ford will certainly be higher.

Leaf blowers are stupid.

I thought that said CO2?

[Flieger]

I agree that leaf blowers are stupid.

Point the leaf blower at the coal of your campfire in the ring and you get a HUGE fire.

[Flieger]

OK, I did not look hard enough.

Flieger,

You just don't get hassled enough at smog time . I have sweated enough bullets with my old SC to where I know (too) much about smog checks!

The "perfect" combustion chemical formula is: O2(oxygen) + HC(hydrocarbon) --> CO2(carbon dioxide) + H20(water).
-"Stochiometry" is when this takes place, at a mixture ratio of 14.7:1 with complete combustion. In real world circumstances, there are many variables which affect this.
-The amount of CO2 produced is generally the measure of HC combusted(usually engine size).

HC is the byproduce of incomplete combustion. It is like raw fuel from the tailpipe.

NOX(Nitrous oxides) is formed under conditions of 2400+deg (hot/high compression engine), and with an excess of O2.
-NOX is usually "cleaned up" by the second half of 3-way catalytic converters which contains the more expensive paladium.

CO is the product of incomplete non-stochiometric combustion(too much fuel)
-The first half of a catalytic converter(the old 2-way cat) cleaned up CO by spontainiously combusting it with ambient O2 over plates of platinum. That's what the old air injector pump was for.

Leaf blowers don't have catalytic converters.


That picture lies because it only shows precentage versus grams/weight of the actual pollution emmited into the atmosphere.
1% of a million(10,000) is much more than 10% of a thousand(100).

It is in parts per million = 1 PMM = 1/1000000
1 % = 1/100, so 1 PMM = 0.0001%

What is skewing the picture is that the total volume of exhaust on the Ford is probably 100 times that of the leaf blower and 4 times that of the Fiat.

(thanks for the correction george)

[yetibone]

Ok. I'm gonna get proactive, and start driving my lawnmower to work instead of driving that dirty little leaf blower all the time.

[jyl]

So the Raptor emits a lot more pollutants than the Fiat, and (gas) leaf blowers are stupid.

[sammyg2]

In California, the day leaf blowers were invented is a state holiday.

And the volume is simply a function of displacement multiplied by volumetric efficiency for the 4 strokes, on the two stroke it's doubled.

[vash]

all my 2-stroke stuff (stihl and echo) all have some sticker on it that says they meet strict emission codes for the first 10 hours of operation. after that, i assume all bets are off. weirdest code requirement ever.

[hardflex]

If the raptor actually "cleans the air' going in, how do you know if it's emitting or it's just residual from the intake air....

It would appear the Raptor drivers should get a break on gas taxes for doing 'community service'
