Summary:

This paper presents some of the modelling and experimental work being carried out at the University of Melbourne, in collaboration with CMC Research, on their new Scotch yoke engine concept. It begins with an overview of the engine, its compactness and friction advantages. The development of a one dimensional squeeze film' model is outlined and some simulation results are presented for both a motored and fired engine. A novel feature of the model is the introduction of an un-filled factor' to account for the dynamics of the oil film volume particular to this type of linear bearing. Experimental results are presented to highlight the important features and serve as a means of validating the model predictions. Comparisons show that the squeeze model correlates reasonably well with the experimental data and it is concluded that the current, flat, bearing design works by a predominantly squeeze film mechanism. To permit the investigation of alternative geometries, which may enable hydrodynamic lubrication, a multi-dimensional model is being developed. A brief description of the models features is provided, along with the proposed outcomes from its application
