Air Pollution Can Land You In Jail


Recommended Posts

Postulate - Air pollution can land you in jail 

 

Proof -

Consider the following series of physiological events - 

 

air pollution increases -> respiratory distress -> increased anxiety -> more tension -> more irritability and anger -> expression of anger (verbally or physically) -> incarceration for felony (due to series of prior events)

 

So the next time you find yourself behind bars for no apparent reason, think twice ... may be the PM level was too high (PM = particulate matter).

 

QED

 

Do you agree ?  :vava:

Why do you post such random, meaningless bollocks? Look.

So the next time you find yourself behind bars for no apparent reason, think twice ... maybe the reason is whatever.

As Farming Guy said .....   They used to issue charges to drivers whose exhaust pipes emitted polluting fumes and/or smoke.  You still see some semi's using cheap oil with that problem.  Don't think they go to jail but they do get ticketed.  Collect enough tickets and ?????  Maybe jail?

Does anyone know if an individual is allowed to describe how the emissions test was cheated?

Why would you not be allowed to do this? Defamation, if you got it wrong?

 

Unlikely, esp. if you cover yourself by saying it is your understanding, rather than incontrovertible fact. There have been countless newspaper article on this in any case.

Well, I read about it somewhere, so descriptions must be allowed.  The engineers wrote the software to disable the  emissions limiting devices so as to provide optimum vehicle performance.  When emissions testing equipment equipment was connected, the software would sense that and enable all of the emission control devices so the vehicles could pass the tests.

The modern diesel engines burn a lot cleaner than the old ones, largely to computer controls and the refinement of common rail fuel injection.https://en.wikipedia.org/wiki/Common_rail  There are also now required to have emission control devices.  There are aftermarket delete devices that can be plugged in to the computers on these vehicles that turn off all of the added emission control devices, and they even sell exhaust kits without emission controls that are made to visibly look like they have the emission control devices.  These law breaking activities are done to boost power and/or improve fuel efficiency, as well as prolong engine life.  There are hefty fines for getting caught.

 

Our older technology farm tractors have little set screws on the fuel injection pumps that can be turned to increase the fuel output to boost power.  In the 1990s they started attaching stickers identifying fuel injection pumps as emission control devices and stated that violation of the law could incur a fine of $10,000.

It's not so indirect as all that.  Just check with those engineers at Volkswagon!

It is my understanding that an additional chip was fitted to the power steering, before leaving the factories, to detect if there was any movement of the steering wheel whilst the car was moving. If there was none, it would put the car into ‘clean’ mode to cheat the rolling road emission test, reverting back to ‘dirty’ mode when it detected steering wheel movement at the end of the test. I was amazed at how simple, but effective, this method of foiling the world’s diesel car emissions regulations appears to have been. We need to be watchful.

I think there was a lot more to it than just the steering, but from this report it does indeed seem that motion of the steering wheel may have been among the inputs to the defeat device algorithm: https://www.bbc.co.uk/news/business-34324772

 

As you imply, simply sensing steering would have been too obvious. It was combined with detecting the type of driving cycle that the official test protocol follows.
