Abstract: A method for controlling the fuel supply of an internal combustion engine having a throttle valve in the intake air system is provided. It is detected that the crankshaft of the engine is at a predetermined crankshaft angular position. At every detection of this crankshaft position, the pressure in the intake air passage downstream of the throttle valve is detected. The present reference value P BAVEn  having predetermined functional relations regarding the present detection value PBAn of the pressure in the intake air passage and the preceding reference value P SAVEn  is set. The amount of the fuel supply into the engine is determined on the basis of this present reference value P BAVEn . The presumptive value of the intake air absolute pressure is calculated in consideration of the correction values with respect to the time lag in control operation and to the fuel deposition on the wall surface in the intake air manifold. Therefore, the proper reference fuel supply amount into the engine can be accurately determined, so that a driveability is improved.

Abstract: The present invention relates to improvements in communication procedures, especially in networks which include at least one device which is capable of being manually switched to an off-line condition. In accordance with the invention, when a switch on such a device is thrown to the position which would place the device in an off-line condition, the device formulates and transmits a message to indicate that it is going to a temporary off-line condition. This message can be used at other devices which are connected in the communication network. Such a message can be employed at a network focal point for maintaining such a device in a polling loop regardless of the fact that the device may, for some period of time, fail to respond to any polls. Such a message can also be employed in any device which was in active communication with the device at the time it was placed in the temporary off-line condition to queue a restart request. In accordance with the invention, when the device which had been placed manually in an off-line condition, is again restored to the on-line condition, it will be in a a condition to respond a poll from the network focal point is informed that the device is again capable of communicating, and any device which has a restart request pending for the device can enable the restart request.
