Abstract
A system for removing effluents from the exhaust gases of an engine includes an auxiliary occupational emissions device positioned downstream of a vehicle-regulated emission abatement system. One or more glow plugs is positioned between the vehicle-regulated emission abatement system and the auxiliary occupational emissions device. The glow plugs are operable to heat exhaust gases exiting the vehicle-regulated emission abatement system prior to advancement into the auxiliary occupational emissions device. A method of lighting off an auxiliary occupational emissions device is also disclosed.
Claims20
An apparatus for removing effluents from exhaust gases of an internal combustion engine, comprising:
- a vehicle-regulated emission abatement system configured to receive exhaust gases exiting the internal combustion engine,
- an auxiliary occupational emissions device positioned downstream of the vehicle-regulated emission abatement system to receive exhaust gases exiting the vehicle-regulated emission abatement system, and
- one or more glow plugs positioned between the vehicle-regulated emission abatement system and the auxiliary occupational emissions device, the glow plugs being operable to heat exhaust gases exiting the vehicle-regulated emission abatement system prior to entering the auxiliary occupational emissions device.
A method of treating exhaust gases exiting an internal combustion engine, comprising:
- advancing exhaust gases from the engine through a vehicle-regulated emission abatement system to produce treated exhaust gases,
- heating the treated exhaust gases with one or more glow plugs, and
- advancing the heated, treated exhaust gasses through an auxiliary occupational emissions device.
An apparatus for removing effluents from exhaust gases of an internal combustion engine, comprising:
- a vehicle-regulated emission abatement system configured to receive exhaust gases exiting the internal combustion engine,
- an auxiliary occupational emissions device positioned downstream of the vehicle-regulated emission abatement system to receive exhaust gases exiting the vehicle-regulated emission abatement system, and
- an electrically-actuated heat source positioned between the vehicle-regulated emission abatement system and the auxiliary occupational emissions device, the electrically-actuated heat source being operable to heat exhaust gases exiting the vehicle-regulated emission abatement system prior to entering the auxiliary occupational emissions device.
