Why Does Duramax Have This Exhaust Tip?

It's for the venturi effect and allows the exhaust gases to be cooled before the. exit the tip, which then reduces the chance of burning someone or catching something on fire.

The 1,000 degrees fahrenheit exhaust during re-gen is pretty hot, with paper burning at around 480 degrees, or so we are told. I could understand why you might want to cool down. Diesel emissions technology really has helped to clean up the cities, even if it some places it's pretty silly like on farms and remote areas. But I guess you can't have one farm tractor to work the land in Southern California where pollution is a problem while in South Dakota there is little issues with air pollution.

Mankind

Man’s ability to alter his environment has developed far more rapidly than his ability to foresee with certainty the effects of his alterations. It is only recently that we have begun to appreciate the danger posed by unregulated modification of the world around us, and have created watchdog agencies whose task it is to warn us, and protect us, when technological “advances” present dangers unappreciated—or unrevealed—by their supporters. Such agencies, unequipped with crystal balls and unable to read the future, are nonetheless charged with evaluating the effects of unprecedented environmental modifications, often made on a massive scale. Necessarily, they must deal with predictions and uncertainty, with developing evidence, with conflicting evidence, and, sometimes, with little or no evidence at all.

CO

Not knowing the difference between carbon monoxide and carbon dioxide is the not knowing the difference between death and life. 🙍🏼‍♂️☠

Humans create both when they burn calories in their bodies. Carbon dioxide is the normal byproduct but any burning process has some incomplete combustion creating carbon monoxide including human cells.

Carbon monoxide is very poisonous to muscles including the heart so red blood cells have a strong affinity to it to purge muscles of it. But excessive carbon monoxide in red blood cells reduces the ability of them to also carry oxygen, which leads to suffocation.
