Abstract

Start-up method for heating a selective catalytic reduction (SCR) module in a hybrid propulsion system of a vehicle, comprising an electric motor operatively connected to an internal combustion engineproducing exhaust gas, both electric motor and internal combustion engine being operable to power said vehicle, and said internal combustion engine being in fluid communication with an exhaust after-treatment system having an exhaust passage and comprising the SCR module, said SCR module being disposed in said exhaust passage downstream of said engine and said electric motor, the method comprising the steps of: operating the engine in a start-up mode with a torque restriction on the engine, allowing the SCR module to convert NOx emission; supplying a surplus amount of a reducing agent to theexhaust gas at a position between the engine and the SCR module, the surplus amount of the reducing agent being larger than a required amount of reducing agent for converting NOx emission from the engine; heating said SCR module to a working temperature; and terminating the start-up mode, thereby terminating the torque restriction on the engine and the supply of the surplus amount of the reducingagent.

Description

technical field [0001] The present invention relates to a start-up method for heating a Selective Catalytic Reduction (SCR) module in a hybrid propulsion system of a vehicle. Furthermore, the invention relates to a control unit configured to carry out a starting method for heating a Selective Catalytic Reduction (SCR) module in a hybrid propulsion system of a vehicle. Furthermore, the invention relates to a vehicle comprising a control unit configured to perform an activation for heating a Selective Catalytic Reduction (SCR) module in a hybrid propulsion system of the vehicle method. The invention also relates to an exhaust aftertreatment system for receiving exhaust gas. [0002] The invention can be applied in heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described in relation to a truck, the invention is not limited to this particular vehicle, but may also be used in other types of vehicles, such as cars, buses, construct...
