Diesel Engine SCR and DPF Regen Systems When Used With Diesel Fuel Additives

Peter M Guerra - VP Technology



It has been brought to my attention that there are increasing concerns about the operation of Diesel Engines with SCR & DPF systems when used with quality fuel additives. There are some fuel additives that claim to improve the efficiency of both the DPF and the SCR systems on new trucks, let’s investigate this further.

First, let me briefly define each of these 2 systems:

• DPF (Diesel Particulate Filter) is the technology that incorporates the high tech filtering/regen processes to remove most solid carbon based emissions from fuel exhaust (the regen process is a costly self-cleaning of the system requiring downtime).  There are several different filtering methods, and a variety of filtering media employed, but the intended result is constant: less emissions. The actual results vary from 35% effective to over 99% success.

Technical Bulletin: Update Water Elimination in Diesel Fuel

Lately there has been an exceptional amount of discussion about the best way to eliminate water from diesel fuel bulk and vehicle tanks. Since fuel injection technology is changing, there are concerns about some of the more traditional ways of handling water in fuel systems.

Recently some vehicle manufacturers have even released bulletins discouraging the use of fuel additives that emulsify water in fuel. I wanted to clearify this matter and assure you and your customers, FPPF products can be used with all the latest fuel injection technologies. Further, FPPF products provide the best solution to water in diesel fuel and gasoline. This is so important, since water remains the number one problem in fuel today.


Basic Definitions / General Problem Solving 

First chemical mixtures like Diesel Fuel, Gasoline and other fuels are hygroscopic or they attract water in all forms. The opposite of hygroscopic is hydrophobic or water repelling chemicals. These chemicals cause water demulsification.

To realize the benefits of today's cleaner-burning ULSD fuels and advanced High Pressure Common Rail (HPCR) injection systems, new diesel detergent technology is required to maximize performance. In order for HPCR injection systems to efficiently produce more power and reduce emissions, the fuel is stored in a central accumulator rail under extremely high pressure (25,000 to 30,000 psi). The fuel is delivered to each electronically controlled injector to provide up to 6 injection events of atomized fuel per combustion cycle. HPCR injection systems provide significant performance improvements as a result ofmore specific internal tolerances (2-3 microns) and higher injection pressures. HPCR diesel injection systems provide quieter, more efficient diesel engine performance, but as with most new technologies, HPCR has created new operational challenges for the diesel engine operator. The operational challenge for HPCR injection systems is Internal Diesel Injector Deposits. These deposits are different and distinct from conventional nozzle deposits as they are produced primarily in the injector valve seat but can also be found in the nozzle areas of HPCR injectors.

A new troubling phenomenon is occurring at times with Ultra Low Sulfur Diesel Fuel.The problem is called diesel soaps formation.Although not a wide spread problem yet,diesel soaps form when they react with surface active agents such as corrosion inhibitors.

Basically, The corrosion inhibitors that are added by the oil refiners at the rack contain salts that when exposed to water become acidic (actually the salt which is an acid combined with a base chemical separate into ions) These acids : (Dodecenyl succinic and Hexadecenyl succinic acid) react with fuel contaminants to form (soap like impurities) This was never a problem until the introduction of ULSD since these products were held in solution by the higher sulfur diesel fuels. With ULSD they can separate out and react with cations (eg sodium, calcium and other metal salts) commonly found in fuel tank water bottoms. Additionally rust and dirt may provide exchange sites that exacerbate the soap formation process.


Biodiesel Additives

The Role of Technology and Economics In Addressing The Problems with Biodiesel

by Mark Ward Senior - NPN Magazing March 2012

Biodiesel has come a long way on the quality front since it was first brought to the market. Manufacturers that diligently follow guidelines set down by the Nation Biodiesel Broad make quality products that are up to the general quality experienced by more traditional fuels. However, there are some specific issues with biodiesel that require extra attention and if the supply source is less consistent in quality precautions can be taken to minimize any issues that might arise.

To understand the situation it helps to being at the beginning. “Biodiesel is a transester of natural oil such as soy bean, rapeseed, canola or meat tallow,” says Peter Guerra, vice president of marketing for FPPF Chemical Company Inc., a Buffalo based maker of diesel fuel additives. “But natural oils won’t work in an engine. You must remove the glycerine and turn the product into an ester.”
