Abstract

The invention discloses a diesel engine drag reduction starting device. The diesel engine drag reduction starting device comprises an electromagnetic clutch device and a control device, wherein the electromagnetic clutch device is connected between the free end of a crankshaft of a diesel engine and an accessory belt wheel and is used for controlling the transmission and disconnection of force between the crankshaft and the accessory belt wheel, the control device is used for controlling the electromagnetic clutch device, and the control device controls the electromagnetic clutch device to act, so that no force is transmitted between the crankshaft and the accessory belt wheel, and the non-starting stage of the diesel engine is controlled by the control device to reset the electromagneticclutch device to enable the transmission force between the crankshaft and the accessory belt wheel. According to the device, the resistance of partial accessories during starting of the diesel enginecan be reduced, the action of the electromagnetic clutch device is stable, the vibration influence is small, the large current of a storage battery can be prevented from being discharged, and the service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to a starting device for an engine, in particular to a drag-reducing starting device for a diesel engine. Background technique [0002] In order for the engine to enter the working state from a standstill, it must be driven by an external force to drive the crankshaft of the engine to cause the piston in the cylinder to reciprocate and perform a working cycle; once the engine enters self-running, the starting of the engine has been completed. Generally, the starting time of a gasoline engine does not exceed 5S, and that of a diesel engine does not exceed 15S. [0003] The starting of the electric starter is to start the engine by converting the electric energy of the battery into mechanical energy; in the short-term starting process, it is necessary to overcome the frictional resistance of the moving pair, the compression resistance of the working fluid, and the resistance generated by the operation of accessories. At the moment ...
