Abstract
A method of heating a cabin of a motor vehicle that includes an internal combustion engine operatively connected to an exhaust system having a catalyst, and a heating, ventilation, and air conditioning (HVAC) system is provided. The method includes detecting a request to increase temperature inside the cabin, supplying fuel and air to the engine, and motoring the engine to pump the fuel and air into the exhaust system. The method also includes heating the catalyst to combust the fuel and air inside the catalyst such that a stream of post-combustion exhaust gas is generated. The method additionally includes channeling the generated stream of post-combustion exhaust gas to the HVAC system such that a temperature of a coolant circulated through the HVAC system is increased to heat the cabin. A system configured to perform the above method is also disclosed.
