Comment Re:And my guess is that is wrong (Score 1) 196

What I'd like to see is a study of gasoline vs. diesel exhaust exposure in a "normal" concentration environment, as far as cancer rates go.

My understanding is that gasoline particulates, due to the particulate matter being smaller in mass, hung in the air for longer (exposing more people) and went further into the lungs (causing more damage) than diesel particulates.

Sure it's gone?

In a direct battle lines war, sure, the people are far out-gunned.

But, look at how much of a pain in the ass the Iraqi insurgency was against the US military. That's a bunch of uneducated, dirt-poor people using what they could, and not actually being there for the attack, and not winning, but being fairly effective.

Better to pay a weight and odometer tax.

Set the per mile tax rate based on vehicle weight, going up with the fourth power of vehicle weight (which is one figure given for the damage done to roads by heavier vehicles). Then, tax the odometer based on that rate.

Fuel taxation doesn't cover alternative-fueled vehicles very well.

Of course, you could have an additional non-renewable fuel tax, to compensate for the cost of using up a non-renewable resource, and any health issues caused by the emissions.

The bottom ends ARE very beefy, but they can't handle a slug of oil going into a cylinder very well, nothing can.

A stuck-shut wastegate could cause a massive overboost condition that could cause various failures of the turbo - turbine overspeed causing the bearings to wear out, excessive stress causing the shaft to snap, a combination of worn out bearings and excessive stress causing the turbine and/or compressor to rub against the housing, etc., etc.

Either of the first two would cause oil to pour into the intake.

The interesting thing about diesel particulates is that they're not the problem.

Diesels don't emit much in the way of microfine particulates, ESPECIALLY ones that are spewing clouds of soot - they emit big huge (easily visible to the eye) particulates that fall out of the air relatively quickly, and don't go nearly as deep in the lungs as the microfines from gasoline engines.

In other words, what you can see is relatively harmless, what you can't see is the really dangerous stuff.

Well, doesn't sound like a problem if you don't care about the (presumably stock) turbo blowing, dumping a ton of oil into the intake, causing a runaway, possibly bent rods, and possibly shot bearings.

Open means it's slow as molasses, but at least the turbo isn't gonna blow.
