Abstract

A method for operating an engine arrangement with a first internal combustion engine and a second internal combustion engine in a vehicle is provided. The method may include partially coupling a first crankshaft of the first internal combustion engine in the vehicle with a second crankshaft of the second internal combustion engine in the vehicle to start the second internal combustion engine, where the first crankshaft and second crankshaft are partially coupled with a clutch. The method may further include decoupling the first and second crankshaft when the second engine is operating under its own power. The method may further include coupling the first crankshaft and the second crankshaft, where the first and second crankshafts are coupled with the clutch when a speed difference between the first and second crankshafts is below a predetermined value and a relative angular position between the first and second crankshafts is less than 360°.
