after treatment system consists of
- Diesel particulate Filter
- Selective Catalytic Reduction
Regenration
process of converting soot collected from in the aftertreatment DPF into carbon dioxide. requires heat to occur.
two types: passive and active
Passive regeneration
exhaust temperatures are naturally high enough to oxidize soot collected in the aftertreatment DPF faster than the soot is being collected. No incremental actions are required by the engine or operator to keep the DPF clean. Passive regeneration typically occurs when the vehicle is driven at high speeds (ie, highway speeds) and/or under heavy loads.

jake brake
The Jacob’s engine brake is a device, which uses the energy of the engine compression to provide vehicle retardation. Engine brakes provide the maximum retarding power at rated speed; therefore, gear selection is important. The engine brake converts the engine to an energy-absorbing device to reduce vehicle speed. This is accomplished by a hydraulic circuit that opens the exhaust valves near the end of the compression stroke.
The Jake Brake is a hydraulic engine attachment that, when energized, altars the engine exhaust valves operation which converts the diesel engine into an air compressor. This is accomplished by prematurely opening the exhaust valves near the top of the compression stroke releasing the compression pressure to exhaust. The result is an engine retarding effort to the drive wheels.
