METHOD FOR MONITORING A TRACTION MECHANISM DRIVE OF AN INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE FOR CARRYING OUT A METHOD OF THIS TYPE

摘要

Systems and methods are provided for determining the length of a traction mechanism that is part of a traction drive of an engine. In one example, a method includes determining a position of a movable tensioning device relative to a traction mechanism drive using measuring technology, determining an actual length LAS′ of a traction mechanism computationally using the position of the tensioning device, determining a length change ΔL with respect to a predefinable setpoint length LAS computationally using the computationally determined actual length LAS′, and adjusting one or more operating parameters based on the length change.

1. A method for monitoring a traction mechanism drive driving a traction mechanism of an internal combustion engine with a crankshaft, which traction mechanism drive comprises a first driving wheel which is arranged on the crankshaft and a second driven wheel which is arranged on a shaft of an auxiliary assembly, the traction mechanism being guided around the driving first wheel and the second driven wheel, and a movable tensioning device which engages in a force-loaded manner into the traction mechanism and loads the traction mechanism with tensile forces along its longitudinal axis, the method comprising:
determining a position of the movable tensioning device relative to the traction mechanism drive using measuring technology; determining an actual length LAS′ of the traction mechanism computationally using the position of the tensioning device which was determined using measuring technology; determining a length change ΔL with respect to a predefinable setpoint length LAS computationally using the computationally determined actual length LAS′; and adjusting one or more operating parameters based on the length change.
