A new type of single compression machine has been developed to investigate basic aspects of the spray combustion phenomenon. The mechanism of a single compression is different from the usual rapid compression machines, i.e. a crank mechanism is used to make a steady reciprocating motion of the piston and a single compression state can be made without any mechanical impact. By the use of this single compression machine and a high pressure accumulated fuel injection system which was controlled electrically, combustion tests and photographic observations were carried out. From a series of tests , the influences of the surrounding air pressure, the temperature, the fuel injection pressure, and the swirl flow on the ignition delay are shown. Furthermore, the factors affecting the period of the initial stage of spray combustion are shown by introducing a new coefficient of heat release rate of spray combustion.
