An angle of spray of a fuel injection valve is narrowed when a temperature of an internal combustion engine is low, whereas the angle of spray of the fuel injection valve is widened in a low and intermediate load region where the temperature of the internal combustion engine is high. The angle of spray of the fuel injection valve is narrowed and also a spray condition is controlled so that the fuel spray comes unevenly in contact with an exhaust side portion of a valve head of an intake valve, in a high load region where the temperature of the internal combustion engine is high.

An equipment for displaying a specification of behavior of a real time system includes a program memory for storing a plurality of program objects for simulating operations of objects indicative of an arrangement of the real time system and a plurality of graphical symbol objects for expressing operational states of the objects and relationships between the objects in the form of a graphical symbol representation on a display screen. In the equipment, the plurality of program objects are linked with the plurality of symbol objects through an inter-program communication control routine. Each of the program objects, when receiving a message from the communication control routine, is executed for simulation operation according to the received message to thereby generate a new message to be sent to the associated program routine and a new message indicative of an object state change to be sent to one of the symbol objects corresponding to the associated object. Each of the symbol objects, when receiving the message from the communication control routine, is executed to change a display state of one of symbols corresponding to the associated symbol object on the display screen.
