摘要
A method provides torque assistance to a crankshaft of an internal combustion engine 3. An electric machine (39 see fig 3) provides assistance in response to the operation of an exhaust gas recirculation valve 29, 35. The need for the invention arises because a valve 29 may need to be opened temporarily to avoid a large quantity of condensate forming which may damage a compressor 11a of a turbocharger 11. The method may also include reducing a fuel injection quantity in response to the valve being operated. The system also includes an exhaust gas treatment module 23, a fuel injection system (49 see fig 3) and a high pressure exhaust gas recirculation loop 31.
