Abstract:
1. A method for heating a lubricating system of rotating or oscillating components for a combustion engine comprising at least one oil suction tube disposed in an oil sump, oil return lines for returning oil from the engine to the oil sump, an oil bypass line which bypasses the oil return lines, and a bypass valve disposed in the oil bypass line, comprising pumping oil through the bypass line via a pump in a pressure line, the bypass line being connected to a pressure line of the lubricating system downstream of at least some devices to be lubricated and to a suction tube of an oil pump, thus bypassing the oil return lines, routing the bypass line through at least one of a cylinder head and at least one turbocharger of the combustion engine, whereby oil is directed from the at least one of a cylinder head and at least one turbocharger downstream through the bypass line to enter the oil suction tube, and at least partially opening the bypass valve if a certain temperature limit is underrun and a certain minimum pressure is exceeded of the lubricating oil in the pressure line of the lubricating system to feed the lubricating oil directly back to the oil pump via the bypass line, so that at least a partial flow of the lubricating oil in a warm-up phase of the lubricating system does not flow through the oil sump until either the minimum pressure or the set temperature limit are reached.
