Lubricant Viscosity

A technique for estimating the piston ring film thickness by measuring the ring end gap has been developed. This paper discusses the details of the measurement technique, presents the results of a parametric study of the measured film thickness for unpressurized full-size diesel engine piston rings and compares those results with an analytical model. The film thickness is shown to depend upon the lubricant viscosity, the piston speed, the ring face profile and the quantity of lubricant available to the ring. The results of an analytical model, which assumes flooded lubrication conditions is also presented and the resulting film thicknesses are similar to those measured.

Test Result

On the diesel engine’s test bed, this paper has studied the parameters regarding the diesel engine’s rotational speed, the piston ring’s width and wearing capacity and so on, and their relation with the output signal of the magnetoresistive sensor under the reverse drawing of the diesel engine. The research discovered that the piston ring’s wear and the magnetoresistive sensor’s output have the corresponding relationship. And on the oil tanker with the 6RTA52U diesel engine, the influence of the diesel engine’s operating parameters and the load situations to the magnetoresistive sensor’s output is surveyed under four kinds of different operating modes. The test result and the research conclusion provide the technical foundation for the online Wear monitoring of the large-scale marine diesel engine’s piston ring.
