High Altitude and smoke - Ernie E - 10-24-2009 02:37

While traveling at spots over 5000 feet, I have noticed lots of black smoke on
start up or getting on freeway. Is this due to the fact there is no oxygen and I
can't breathe either?

Lighter foot, save fuel...It's down hill from Williams to the Colorado River.

Ernie, here is where the newer computers make up for the faults in the fuel
delivery equatons of the mechanical systems.

you are dumping fuel into the cylinders but cant pack enough oxygen rich air in
to completely burn the fuel. the same volume of air at a lower altitude has a
much higher concentration of oxygen which would burn all the fuel. not sure if
the modern computers deal with the elevation factor or maybe they deal with the
opacity condition?

I get several calls a month (trucksmog.com) from Diesel pickup drivers who got
tickets for excessive smoke and need to be certified as factory year compliant.
Usualy kids with new trucks that re-chip or add a aftermarket chip that tells
the computer to 'dump 100% requested fuel when the driver hits the pedal,
without reguard to the ability to burn. Turbo must be spinning fast to pack the
air (turbo boost) to burn the fuel at any given time.

the problem with turbos is :the more fuel you burn, the faster they spin, so
they can burn more fuel. the progressive process leaves acceleration with a
dynamic called 'turbo lag' where the turbo is not at speed to pack enough air
yet.

Curt's suggestion is that which a computer would demand to the delivery of fuel.

I've noticed that too on my Ford diesel, when we were in Arizona/Rockies two years ago, lots of black smoke. However, after getting to lower, flatter elevations, it went away. My 93 doesn'thave all kinds of fancy equipment to adjust the air/fuel ratio to handle that.

Yes ... although the turbo charger should help (the engine). You'll need to get supplemental oxygen for yourself. Still, the lack of oxygen in the air at higher elevations will cause some signs of incomplete combustion in both the engine and generator engine.
Check your air filter, to make sure that it isn't contributing to the problem.
If shortness of breath kicks in at 5000 ft, you might want to do a little more aerobic-type exercise at lower elevations to build up your tolerance -- but you must remain at a higher altitude for 2 to 3 weeks for your body to make some adaptations that will help reduce the breathing stress.

Down here at 480 feet, the smoke was a whole lot less.

High Altitude and smoke - duesenmaschine - 10-27-2009 10:20

Ernie
i was camped in Flagstaff once and when I started my motor, I almost got lost in
the campground. The traffic on the street, which i entered, got their green
light , but couldn't move due to my reducing visibility to 0 feet. The smoke
cleared shortly then. Later I learned from an experienced coach operator that if
you light a fire (start a diesel) you get lots of smoke, high altitude and thin
air will cause this, so just be light on the throttle and make sure no cops are
around. Black smoke is only too much fuel and not enough air.
And the experienced coach operator might be on this web site. His name is Fox,

Thanks Jurgen. When it is cold out I always have my block heater on- especially if I'm in a campground.
