Method for operating an internal combustion engine with a divided crankshaft and synchronizing clutch to the coupling of two crankshaft parts of an internal combustion engine

摘要

The present invention relates to a method for operating an internal combustion engine with a first, exclusively operated main motor with a first crank shafts part and a second, by means of a synchronizing clutch can be coupled with the supplement motor with a second crank shafts part, wherein the synchronizing clutch of a a predetermined slip speed between the crank shafts parts of the state of the friction clutch and a in the case of adjustment of the slippage rpm to a synchronously position with an exact rotational angle position of a predetermined ignition of the internal combustion engine with coupled crank shafts parts of a positive engagement of these adjusting or be positively locking coupling is formed, and a corresponding synchronizing clutch for this purpose. In order to achieve a synchronization quickly and without high switching moments to be able to carry out, during a synchronous operation of the two crankshaft parts in the case of the supplement motor and, initially, the open position of the synchronizing clutch in particular with a spring-loaded formation of a form fit, a clutch torque is transmitted via the friction clutch to the predetermined slip speed between the crank shafts parts is regulated, the addition of the engine is started and synchronously position, by the acceleration of the crank shafts part of the addition of the engine is started and the positively locking coupling is closed.
