Abstract

An exhaust system (100, Fig.2) for a vehicle (1, Fig.1), and an associated method (600, Fig. 6) and computer software (408, Fig. 4); The exhaust system (100, Fig. 2) comprises a turbomachine assembly 120 and a component (202, 204, Fig. 2) of a heating system (200, Fig. 2) for raising a temperature of an exhaust gas aftertreatment device (152, Fig. 2); The turbomachine assembly 120 comprises a turbomachine housing 126 with: an inlet section 126A having an exhaust gas inlet port (130, Fig. 2), a turbine volute 126B, and an outlet section 126C extending from the turbine volute 126B and having an exhaust gas discharge port 135; The outlet section 126C of the turbomachine housing 126 further comprises an opening 132, 134 wherein the component (202, 204, Fig. 2) of the heating system (200, Fig. 2) is received in the opening 132, 134. The invention aims to speed up the heating process of an exhaust gas aftertreatment device.
