In the first Report, the authors proposed a new conception of the fuel injection control system which would theoretically make it possible to optimize the injection period and quantity of fuel freely in any operation mode of the engine by adjusting the injection pressure, and reported on the results of the relevant basic experiments. The authors applied the above system to a pre-combustion chamber type engine and carried out some experiments to search for the optimum injection pressure. Further, by means of inserting8 an optical fiber probe into the combustion chamber, the authors investigated the influence of the injection pressure upon the behavior of combustion. The second Report briefly describes the results.
