Abstract
The automobile industry in Japan is moving towards high-per formance and highquality engines, which are high-powered and compact. In Europe and America, this goal has already been achieved and multicylinder high-powered engines have been developed. The maximum number of cylinders in an engine for a motorcar in these countries is 16 cylinders in a V-type and this engine is used in sports and racing cars. The next largest engine size below the 16 cylinders is the V-type 12-cylinder engine which is widely used in many luxury vehicles. In Japan, however, although the V-type 12-cylinder engine is the largest, it is loaded only into one type of car. In this paper, we analyze the exciting moment of the V-type 14-cylinder engine which is positioned between the V-type 16-cylinder and 12-cylinder engines, but does not yet have a practical use as a motorcar engine. Here, we consider the characteristics and evaluate the V-type 14-cylinder engine for use in a motorcar.
