Monitoring apparatus, as well as monitoring method for monitoring a state of wear of a component for a reciprocating piston internal combustion engine

摘要

The invention relates to a monitoring apparatus for monitoring a state of wear of a component of a reciprocating piston internal combustion engine wherein an oil collection device is provided for the collection of lubrication oil from the cylinder so that a predetermined measured quantity of lubrication oil is suppliable from the cylinder to a measurement device.

主权项

1. A monitoring apparatus for monitoring a state of wear of a component of a reciprocating piston internal combustion engine comprising:
a cylinder having a cylinder cover and a running surface provided at a cylinder wall of the cylinder; and, a piston arranged in the cylinder and moveable to and fro in an axial direction along the running surface between a bottom dead center and a top dead center such that the piston, the cylinder cover and the cylinder wall form a combustion space in the cylinder for the combustion of a mixture of a fuel and air, wherein an oil collection device is provided for the collection of lubrication oil from the cylinder so that a predetermined measured quantity of lubrication oil is suppliable from the cylinder to a measurement device, wherein the measured quantity of lubrication oil is directly suppliable from the running surface of the cylinder and/or is directly suppliable from the combustion space and/or is directly suppliable from a piston ring package of the piston to the oil collection device wherein the measurement device includes an electromagnetic measurement unit, of a magnetic permeability, of an electric DC conductivity and/or of an AC conductivity, and/or of a complex electric conductivity and/or of a complex electric resistance of the collected measured quantity of lubrication oil, and wherein the monitoring apparatus is provided miniaturized directly in the cylinder wall.
