A plurality of engine operating parameters and useful information items are monitored by respective sensors. A control unit receives signals from the sensors to display the monitored items in a varible format on a single viewing screen in accordance with the conditions of the monitored items. Abnormal condition of the monitored items is detected by the control unit to enlarge the display format to give an warning indication. A pushbutton is provided for each of the monitored items to generate a display command signal in response to a manual command to provide a display of a desired item in an enlarged format.

An automobile air-conditioning control apparatus includes a microcomputer which is responsive to the output signals of a compartment temperature sensor for sensing the temperature of the vehicle compartment of an automobile and temperature setting means for setting a desired temperature to be controlled to perform digital computational operations. The position of flow direction changing plate means and the rotational speed of blower motors are automatically controlled in accordance with the command signals from the microcomputer.

Air-conditioning control apparatus for automotive vehicles

A system for indicating an abnormal condition of an automobile in which the condition of inspection items relating to the driving of the automobile is detected, and running speed of the automobile is detected. The system decides that the condition of an inspection item has reached a first abnormal level, and upon detection of the stoppage of the automobile after the time point of the decision, a voice cautioning the driver of the abnormal condition of the inspection item is automatically generated. Upon detection of the fact that a second abnormal level higher than the first abnormal level has been reached, a voice warning the driver of the abnormal condition of the inspection item is generated regardless of the driving condition of the automobile.

Method and system for indicating automobile abnormal conditions

A fuel injection system for an internal combustion engine of the type so-called unit injector wherein the overflow of fuel under high pressure from a plunger chamber defines the fuel injection cut-off. In order to perform the sharp cut-off, an overflow passage is increased in cross sectional area, and in order to prevent the overflow from the plunger chamber while the fuel is being charged into it, a flow control means such as a spool type directional control valve is inserted into the overflow passage so that when the fuel is being charged into the plunger chamber the communication between the overflow passage and a fuel tank may be positively interrupted. In addition, in order to prevent the fuel recharge with the resulting secondary injection, a flow control means such as a solenoid operated directional control valve is inserted into a fuel supply line communicating between a fuel delivery source and the plunger chamber such that as long as the fuel injection continues or when the fuel injection is zto be completed, the communication between the plunger chamber and the fuel delivery source may be completely cut off.
