| Abstract;Piston skirt friction has been considered to be related to cylinder block bore distortion and piston secondary motion, but it has been studied almost exclusively in isolation, and its detailed relationship to the functioning of an actual engine has not been clarified. We used computer simulations to reproduce cylinder block bore distortion and piston secondary motion in combination to try to increase our understanding of their relationship with an actual engine. First, calculated results were compared with measured values to ascertain their validity. Next, the technique was applied to the development of an actual engine, and the engine performance was studied along with the establishment of a method to predict friction. The application of the new simulation technique in engine development resulted in increased reliability and a reduction in friction of approximately 2%, demonstrating the effectiveness of the method.
