HEATING SYSTEM FOR A VEHICLE HAVING AN EXHAUST SYSTEM

摘要

A heating system for use on an exhaust system having an exhaust gas passageway, the engine having a cooling system to circulate a cooling fluid to and from the engine, includes a fuel-dosing member for dosing fuel to the exhaust system to trigg er a regeneration event. A particulate filter is located on the exhaust gas passageway downstream of the engine, and an oxidation catalyst member is located upstre am from the particulate filter. The oxidation catalyst member oxidizes the fuel dosed to increase the temperature of the exhaust gases. The increased temperature causes a regeneration event at the particulate filter, which further increases the temperature of the exhaust gases. A heat exchanger is located downstream of the particulate filter for capturing heat from the exhaust gases. The heat exchanger has an inlet conduit and an outlet conduit for circulating the cooling fluid from the heat exchanger to the engine cooling system.
