According to records filed in the case, Achtemeier conspired with mechanics in garages and operators of truck fleets to disable the anti-pollution software installed on diesel trucks.
Coconspirators who wanted to disable their trucks’ pollution control hardware system—a process commonly known as “deleting”—sought Achtemeier’s help to trick the truck’s software into believing the emissions control systems were still functional, a process known as “tuning.”
Monitoring software on a deleted truck will detect that the pollution control hardware is not functioning and will prevent the truck from running. Achtemeier disabled the monitoring software on his client’s trucks by connecting to laptops he had provided to various coconspirators. Some of the coconspirators would pass the laptop on to others seeking to have the anti-pollution software disabled on their trucks. Once the laptop was hooked up to the truck’s onboard computer, Achtemeier could access it from his computer and tune the software designed to slow the truck if the pollution control device was missing or malfunctioning. Achtemeier could “tune” trucks remotely, which enabled him to maximize his environmental impact and personal profit.
The antipollution on a diesel engine (at least a big one) essentially reroutes the exhaust back through the engine and reburns it again. Before the antipollution devices were in place it wasn’t uncommon for big diesels to get 500,000 miles before they needed to be replaced. Now with the antipollution devices they’re getting somewhere in the neighborhood of 100k before they start having problems of significance.
Those engines and their maintenance are expensive as hell. It saves a whole lot more than the $4,500 having that done. It saves them hundreds of thousands of dollars over the long haul.
I actually decided to search this because I thought the whole point of DEF was so trucks wouldn’t need to use an EGR like every car does.
Apparently emissions is complicated and expensive lol, so lots of trucks have both.
Newer models however have started creating systems that remove the EGR and instead rely solely on the SCR with a bigger DEF tank and a cleanup catalyst.
I think DEF is still the right direction. Exhaust recycling has a ton of downsides that took car OEMs a while to hack their way around (or give up and plan for 150k mile expectancy).
4,500 for a mod though is still pretty expensive for something you can do yourself. Most of that cost was probably due to it being illegal, not because it’s hard to accomplish.
or they could run on propane, which doesn’t make a whole lot of particulates in the first place and is cheaper anyway
I’m talking big trucks not forklifts.
out there plenty of people run their cars on LPG, most of taxis in Warsaw are hybrids running on propane because it’s cheapest fuel in most efficient vehicle in urban conditions
it’s pretty common in US too, just not in private vehicles https://en.m.wikipedia.org/wiki/Autogas#/media/File:2020_Global_Autogas_Consumption.svg
Are you defending this?
God I hate comments like this, that are so un charitable. He’s giving us more information and context which is important and adds to discussion and here you are trying to start shit.
This happens way too often on here, people providing nuance or a different perspective and some douche sliding in “so you think everyone should DIE!!!” putting words into OP’s mouth and attributing malice…
A point was trying to be made. One - the information provided is absolutely biased and possibly untrue. Performing maintenance on your vehicle is a fact of life. Using emissions as a scapegoat and justification to pollute bothers me more than my comment bothers you.
Fuck polluters and fuck their apologists.
Everything is on a scale. The pollution control equipment only trades air pollution for increased throughout in landfills, increased industrial emissions to the air, water, and land by necessitating more frequent replacements, as well as more funds in the pockets of capitalists. Pick your poison because you’re never going to come away squeaky clean.
