Abstract
In accordance with example implementations, a vehicle includes a body, an engine within the body, and at least one exhaust tube extending from the engine and having a particulate filter fluidly coupled to the exhaust tube to receive exhaust material from the exhaust tube. The vehicle also has at least one air injection pipe having a first end with an inlet arranged to receive air flow entering the body while the vehicle is moving, wherein the air injection pipe comprises a second end fluidly coupled to the exhaust tube and having an outlet positioned to provide air flow from the injection pipe into the exhaust tube upstream from the particulate filter. Passive soot regeneration with THC and CO reductions is realized by this introduced air flow.
