Legend Posted October 14, 2019 Share Posted October 14, 2019 Neal's right. The rest of you are wrong. Bosch provides the CP4 fuel pumps to GM and Ford that eat themselves up and send shit into the injectors. GM has a different fuel pump now. Diesels are shit now because emissions DPFs, piss injections, regens, etc, and shitty ass fuel pumps. But think about it, they make 400-500ish hp and 1000ft lbs or more FROM THE FUCKING FACTORY. And still get good mpg for a 8k+ lbs truck. Quote Link to comment Share on other sites More sharing options...

Back a modern diesel down to 300 hp and under 600 ftlbs and it would last just fine with all the emission stuff. pre emission diesels would not last at today’s power levels either Quote Link to comment Share on other sites More sharing options...

This will substantially lower emissions of nitrous oxide and particulate matter emissions to the atmosphere. However, the process used to reduce the sulfur content in diesel also reduces the fuel's lubricating properties, resulting in increased wear on the various parts of the engine's fuel injection system.” https://www.ag.ndsu.edu/news/newsreleases/2007/march-8-2007/ultra-low-sulfur-diesel-fuel-affects-lubrication/ Quote Link to comment Share on other sites More sharing options...

Platinum Contributing Member Highmark Posted October 14, 2019 Platinum Contributing Member Share Posted October 14, 2019 There is a misconception that sulfur is what provides the lubricity to fuel oil, but that idea is only indirectly correct. Although the sulfur does contribute somewhat to lubricity, the lower lubricity level of low sulfur fuel is more a by-product of the refinery processes used for desulfurization. In its purest state, crude oil would consist of various bonds of hydrogen (H) and carbon (C ) atoms linked together in chains of various lengths. However, no crude oil is entirely pure, but always contains trace amounts of various impurities. One such common impurity is sulfur; depending upon the crude source, the sulfur content can range from as low as 500 ppm (sweet crude) up to as much as 10 fold (sour crude) that amount. During the desulfurization process via hydrotreating, hydrogen gas is introduced to the crude under extreme temperatures and pressures. The hydrogen combines with the sulfur to form hydrogen sulfides that are then removed and ultimately converted into elemental sulfur for resale. Unfortunately, during desulfurization, critical polar and organic aromatic compounds innate to the fuel and identified as responsible for imparting significant lubricity quality, are destroyed under the necessarily intense operating conditions. The resulting yield is a satisfactory low sulfur diesel fuel, but also one that is unsatisfactorily low in lubricity. WHY THE FUSS ABOUT LUBRICITY NOW? For many decades, it was taken for granted that all distillate fuels, with the possible exception of kerosene, contained enough inherent lubricity to protect against engine wear. There was no reason to define lubricity or to establish a test method to quantify a lubricity value. For the most part, it was assumed that any fuel had the ability to provide adequate lubricity as one of its innate and irreversible properties. However, everything changed once the EPA began to look into diesel fuel exhaust emissions and, early on, identified sulfur as one of the main sources for objectionable smog-causing air pollutants, oxides hazardous to health and long term corrosive acid rain damage. By the late ’90s, the EPA was exploring regulations to reduce the sulfur content of distillate fuels, especially on-road diesel. As the likelihood of new regulations became more imminent and oil refiners investigated available processes available for crude oil desulfurization, one critical piece of information became obvious’that any significant reduction in sulfur content would result in a significant reduction in fuel lubricity as well. Realizing this correlation, ASTM launched a task force to include lubricity requirements as part of its existing ASTM D975 Standard Specification for Diesel Fuels. Concurrently, another task force was assigned to determine an effective laboratory test method to measure lubricity values. https://fueloilnews.com/2010/03/04/taking-the-mystery-out-of-lubricity/ Quote Link to comment Share on other sites More sharing options...

Emissions is the DPF and SCR systems. Fuel pumps that are being chewed up are not emissions. Not the emission equipment pre emission diesels run fine on the ultra low sulphur diesel without issue. Increasing hp to these levels require a lot of tech in the engine.... all emission systems are after treatments.... Back off the hp and you could get by with more reliable engine components.
