In the case of engine bearings, pressure in a cylinder is necessary for the analysis of lubrication. In this study, a cycle simulation of gasoline engines has been developed to predict the pressure in a cylinder under the wide range of engine operation. In the cycle simulation, intake and exhaust processes are included and combustion process is calculated with flame propagation based on burning velocity. The pressure in the cylinder is introduced into the bearing analysis to calculate the load on the bearing in addition to the inertia force. Orbital movement, minimum oil film thickness, and power loss in the bearing are estimated. This method may be useful on an engine design.

Elastohydrodynamic lubrication of a journal bearing has been usually calculated with bearing deformation. In this study, crank-pin deformation is included in addition to the bearing deformation of con-rod big-end. The calculated results are shown with and without the crank-pin deformation and the effects of the crank-pin deformation on calculated results are discussed. The effects of the crank-pin deformation appear after compression TDC during low speed operation and near suction TDC during high speed operation.

“Creative Exercise” is one of the most important articles in the course of technology educations at the universities and the colleges. In this paper, some trials for the creative exercises developed in Osaka Electro-Communication University are introduced ; those are (1) exercises in “Creative Design Engineering”, (2) studies and educations on robots, (3) executive plan of rescue-robot contest, and (4) supporting system for application for the qualifying examinations. Their results and effectiveness are also discussed.
