  A turbocharger, or turbo is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber. The turbocharger is used to deliver a pressurized charge air to the engine’s cylinders and it increases the oxygen density in the air charge.

  

DIESEL PARTICULATE FILTERS (DPFs)

A DPF is now a requirement on every on-highway Diesel engine meeting 2007 emissions and beyond.

By definition, a DPF is an exhaust aftertreatment device designed to eliminate diesel particulate matter (PM), or soot, produced by the engine cylinder combustion process. The DPF substrate is an extruded material, typically cordierite or silicon carbide, that is housed in a muffler body. DPF substrates typically capture over 95% of the diesel PM, but they will plug up unless they are cleaned or regenerated.

There are two main regeneration approaches–passive and active.
