Diesel Engine Cleanliness

Technological advances in modern diesel engines are changing how we think about driving a diesel vehicle.  Diesels and their emissions have traditionally been associated with negative health and environmental pollutants, such as carbon monoxide, nitrogen oxides, particulate matter and un-burned hydrocarbons. There are a variety of reasons for these pollutants to occur in diesel emissions, ranging from fuel combustion being incomplete, combustion of engine lubricant oil,  mixture components reacting under high temperatures and pressure, and non-hydrocarbon components of diesel fuel combustion (including fuel additives and sulfur compounds).  These old negative ideas about diesel vehicles are being examined and effectively mitigated. Modern diesel engines are now being equipped with emission after-treatment devices that are emitting “near-zero” levels of pollutants. Catalysts and particulate filters are among the new devices being used.


Under certain conditions, DPFs (diesel particulate filters) can actually achieve nearly 100% efficiency in soot removal, and even under normal conditions, they typically reach 85% efficiency.  DPFs passively burn off accumulated particulate with the use of a catalyst.  An active process called “filter regeneration” uses a fuel burner that heats the filter to temperatures which will combust the soot. In older models, this regeneration process only occurs properly at higher road speeds. If a diesel vehicle is consistently driven in urban environments, drivers will need to periodically take highway trips at higher speeds, above 40mph.  Drivers who ignore the warning light, or wait too long to activate “filter regeneration” can cause a buildup in the filters.  If the buildup continues past a certain point, it can be completely ruined and require an expensive replacement. There are vehicles that have been recalled, from flames emitting from the exhaust pipe, caused by the buildup of large amounts of soot in the DPF.

Removing the parts and attempting to clean or replace them has proved an unsafe and inefficient, as well as costly, way to solve the problem.  Solutions thus far have tended to address only the symptom and not the cause, as BG Technical Service Advisor, David Tenpenny says, “People in the diesel industry realize this is a real problem that’s not going away and if you want to solve it, you have to fix what’s causing it. If not, you’re just applying a Band-Aid.”

Rather than continuing to view this as a problem, BG Technology Department chose to view it as an opportunity. They developed the BG DPF & Emissions System Restoration Service through two years of research and development. This groundbreaking technology effectively and concurrently performs an intake system cleaning, while also regenerating the DPF. Installed through the BG VIA™ system, the BG Diesel Intake and Emissions System Cleaner (PN 258) provides the capability of cleaning the emissions system by triggering and controlling DPF regeneration using only the touch of a button. From the intake through the entire emissions system, it effectively disperses hydrocarbons that can then be burnt off and emitted through the exhaust pipe. The service does not require the expensive removal of the DPF, as was previously required, and as an extra bonus, this VIA system is listed in Motor Magazine as one of their top 20 tools.

Tenpenny recommends carefully monitoring temperatures, adjusting RMP and a little patience, and he adds, “It’s essential to follow this intense clean-up service with a BG Performance Oil Change with BG EPR, BG DOC and BG 244.” This service reduces the tendency for overloading the DPF with excess soot and enables future self-cleaning to be more effective.
