Many new diesel trucks now include filter technology, more particularly, a device called diesel particulate filter otherwise known as DPF.This device is designed to exterminate diesel particulate matter or what is commonly called soot, and eliminate visible smoke coming from the exhaust pipe. New environmental laws requires manufacturers to strictly comply with stringent standards on particulate emissions from diesel engines. Unfortunately, the process that ensues hampers power and fuel mileage in the vehicle, which is the problem that DPF delete kits address.
As DPF traps the soot in the exhaust, the accumulated particulates are removed through a process called regeneration, which burns the soot at very high temperature. The vehicle’s engine management computer will passively or actively control. Among other things, the process introduces the concept ofback pressure, which is what happens when the spent gases in the exhaust are hampered by the tight bends in the piping or air vents for example. Other testimonials say the regeneration process decreases the fuel efficiency of their vehicle. Eliminating the back pressure problem with DPF delete, thus freeing up the engine to work better, sends more power to the wheels, and allows it to burn less fuel. Some independent tests report an improvement of 4 to 7 mpg.
A standard DPF delete kit wouldusually include a DPF delete pipe, a touch screen programmer, aluminized or stainless exhaust and muffler, dual tailpiles catalytic converter delete pipe and standard tunes. The user may decide the component of the kit depending on the driver’s modification requirement as well as the improvement needed on the vehicle.
Manufacturers of DPF delete pipes, which function as direct bolt on replacement for the factory DPF, also claim that installation of the device can increase as much as 300 horsepower and500 lb/ft oftorque at the same time.The pipes can be used on Ford 6.GM LMM6,, 4L Powerstroke.or other types of diesel engines.7L Cummins Diesel engines, without having to use any check engine codes.
The law only allows DPF Delete Kits to be used in off-road diesel-engined vehicles because it interferes with emissions. Any on-highway vehicles caught using DPF Delete kits will be apprehended and the driver of the vehicle will be meted a fine.. Furthermore, any alteration of emissions components, especially when the kit is used, will void the warranty on the exhaust stack, and even the EGR and turbo. Some users believe the risk of losing warranty on their vehicle’s engine was worth it as the performance of their diesel engine increased dramatically since they installed the kit.
