A method and system of power generating is provided to reduce a startup time of a genset for providing requested power to a utility grid or a load. The genset includes a generator, a turbocharger, and an energy storage. The generator includes an engine. The genset responds to a genset start signal by accelerating an engine speed of the generator to reach a synchronous speed. The engine speed is accelerated more rapidly by activating the energy storage device to supply power to at least one of the generator and the turbocharger. The generator then supplies power to the utility grid or load.

Method and system for starting an internal combustion engine of a hybrid vehicle, adapted to rotate a drive shaft providing torque via a transmission unit comprising a first clutch connecting the engine to an input shaft of a gearbox connected to a torque converter connected to a second clutch connecting the torque converter to the at least one driving wheel, where the input shaft is connected to an electric machine; the method comprising: disengaging the second clutch to a predetermined torque level such that there is a slip in the second clutch; engaging the lock-up clutch; engaging the first clutch to bring the engine to a first rotational speed; disengaging the first clutch when the engine has reached the first rotational speed; starting the engine, and engaging the first clutch when the engine has started and rotates with a second rotational speed.

A method for operating a vehicle that includes a driveline disconnect clutch is described. In one example, the method adjusts torque of an electric machine in response to a estimated torque capacity of the driveline disconnect clutch. The estimated torque capacity of the driveline disconnect clutch is based on a combined inertia of a dual mass flywheel and the driveline disconnect clutch.

A clutch arrangement (3) with a friction clutch (8) and a dog clutch (9), wherein the output side of the friction clutch (8) and the output side of the dog clutch (9) are connectible to a flywheel mass device (4). A powertrain unit having such clutch arrangement is also described.

A coupling device for transmitting a torque from a flywheel mass to a drive device. A ratchet wheel and a transmission element of the flywheel mass ‘SUE’, which is identical to the flywheel mass (or is connected to the flywheel mass, are axially displaceable relative to one another, and pawls of the ratchet wheel can be moved into cutouts of the SUE, and a friction device, particularly in the form of a friction cone, is connectable to the SUE at least partially in a frictionally engaging manner and is connected to the ratchet wheel in a positively engaging manner.
