Abstract
The present disclose is directed to a power system. The power system may include a power source that creates a flow of exhaust. The power system may further include a particulate collection device that receives the flow of exhaust. The power system may also include an additive injector located downstream of the power source, the additive injector may be configured to provide a controlled supply of additive to the flow of exhaust.
Claims20
A power system, comprising:
- a power source that creates a flow of exhaust;
- a particulate collection device that receives the flow of exhaust;
- and
- an additive injector located downstream of the power source, the additive injector configured to provide an additive to the flow of exhaust;
- wherein the additive includes a metal-based additive.
A method of assisting regeneration of a particulate collection device that receives a flow of exhaust from an internal combustion engine, comprising:
- supplying an additive to the flow of exhaust from a location downstream of an exhaust manifold of the internal combustion engine;
- and
- regenerating the particulate collection device after the additive has been supplied to the flow of exhaust.
A power system, comprising:
- a power source that creates a flow of exhaust;
- a particulate collection device that receives the flow of exhaust;
- an additive injector located downstream of the power source and upstream of the particulate collection device;
- at least one sensor configured to sense a parameter of the flow of exhaust and generate a signal corresponding to the parameter;
- and
- a controller in communication with the additive injector and the at least one sensor, the controller being configured to control operation of the additive injector in response to the signal.
A method of assembling an additive injector to an after-treatment system of a power system, comprising:
- coupling the additive injector to a supply of additive;
- coupling the additive injector to a passageway of the after-treatment system;
- and
- connecting the additive injector to a controller associated with the power system, wherein connecting includes supplying the controller with software to control the additive injector to regulate the supply of additive delivered from the additive injector to the passageway.
