Abstract: A method for operating a hydraulic system, in particular a hydraulic system of a motor vehicle, which comprises a hydraulic pump (10) powered by an electric motor (11) operated with rotation-speed regulation, the pump for drawing hydraulic oil from an oil sump (6) and supplying it to at least one assembly (8) that is to be cooled and/or lubricated. As a function of a temperature of the hydraulic oil and as a function of an actual electric current in the electric motor (11) powering the hydraulic pump (10) and/or an actual rotation speed of the hydraulic pump (10) or the electric motor (11) powering the pump, it is determined whether a sufficiently large oil supply is ensured for the at least one assembly (8) that is to be cooled and/or lubricated.

Abstract: The present disclosure relates to an engine assembly for a vehicle. The engine assembly comprises an engine including an extended crankshaft with additional main bearings, an alternator or a generator, a drive chain assembly, and a starter motor assembly. The engine may be used in different models of the vehicle having different characteristics, which enables to interchange or replace an internal generator with an external alternator, and vice versa in addition enable to use a common starter motor assembly, crankshaft, crankcase, and drive chain assembly for both engine configuration without modifying a basic design of the engine. Further, placement of the starter motor assembly provides a compact arrangement. In addition, the extended crankshaft with the additional main bearings enables low noise level operation, avoids additional shafts and roller bearings to be attached, and cost effective. Similarly, the drive chain assembly produces less vibration and noise.

Abstract: A process and apparatus for cooling a heat generating component of a vehicle comprises pumping coolant from a first pump while a first pump is in a chiller mode in a first loop comprising a component heat exchanger and a chiller module. Coolant is pumped from the first pump while the first pump is in a recirculation mode in a second loop comprising a heater module, and a cabin heat exchanger or back to said component heat exchanger. A second pump pumps coolant in the second loop while the second pump is in an isolated mode and from the second pump from the second loop into the first loop while the second pump is in a linked mode.
