Studies: DPF Delete Kits can increase fuel mileage up to 47 percent

Thanks to the new Euro Emissions standards, the legislation which aims changes for vehicle emissions or 2009 and the years to come (specifically an 80% reduction in soot emissions), there will be an increase in the use of filter technology particulate filters in diesel vehicle exhausts – commonly called as diesel particulate filters or DPF. The wall flow type of DPF (also known as “traps”) catch 85-100% of the soot in the exhaust, and remove the appearance of visible smoke. But this might lessen the performance of your engine. A DPF delete kit can address this issue by removing the DPF, thus improving fuel efficiency and the performance of the engine power. But the law states that these DPF Delete kits can only be used on off-road vehicles and is illegal for use in on-highway diesel vehicles.

How does it work? The 6.4 DPF delete works just like any filter, such as the bag in your vacuum cleaner, for example, working to trap dirt and soot from the air of the exhaust into the filter. This filter must be cleaned out to maintain the performance of the engine. In a process called “regeneration,” the diesel particulates are burned at high temperature, leaving a residue of ash in the filter. However, despite the fact that DPF and catalytic converters can scrub away emissions, the process somehow invites a phenomenon called back-pressure, which is a result of the restriction of the flow of the gases out the exhaust as it leaves the combustion chamber. The gases enter the exhaust stack and then make an exit through the tail pipe. The restriction of flow is often thought to be caused by DPF, as well as by catalytic converters, mufflers, and bends in the pipe.

As the back-pressure increases, it adds more pressure to the engine to work harder to release the used gas. The harder the engine works, the more fuel it requires, and less power is also allocated to the movement of the wheels. These combined factors reduce the performance of the engine. The DPF delete kit removes the DPF, thereby reducing backpressure and thus building up engine performance and fuel efficiency.

Some independent tests run on engines after applying the DPF delete kits report a 26 to 47 percent increase in fuel mileage. While it’s true that emissions cleaners like DPF hampers the flow of the exhaust gas flow, it’s also true that free flow in big trucks is already built into the vehicle’s system. The kit also includes a flash device that reprogram the engine’s performance by boosting fuel efficiency using the truck’s on board computer. Thus, it would be safe to say that the DPF delete kit enhances overall performance by addressing these issues including the issue of back-pressure.

DPF Delete is primarily designed to increase engine power as well as fuel efficiency on off road diesel trucks.
