EXCERPT:
CONSTANT IDLE StrEED SYSTEM
Air control valve
The constant idle speed system consist s of an air control valve which regulates idle speed by increasing or decreasing the amount of air bypassing the throttle valves. The air control valve is operated by a control unit.
Not only is idle speed kept constant regardless of engine load, but fast idle is obtained when the engine is cold.
The CIS system replaces:
- auxiliary air valve in CJ-.fuel injection system
- the system for regulating idle speed fitted to vehicles with air conditioning. This system has now been modified to a temperature controlled ignition advance system, see page 5.
FUNCTION (see illustrations on next page)
The control unit receives information from three sources:
o ignition co1! (terminal 1) - gives information on engine speed
o temperature sensor - indicates coolant tempe rature
o microswitch - indicates if throttle is in idle position
This information is then processed in the control unit which regulates the air control valve so that correct idle speed is maintained.
Fast idle
A higher idle speed than normal is required when engine is cold. The temperature sensor indicates if engine is cold and relays this information to the control un it which adjusts the idle speed accordingly. At -20 degree idle speed is about 50% higher than with hot engines1 and decreases as engine temperature increases. Normal idle speed is reached at a temperature of approximately 15 degree (590f).
Idle
When engine is hot, idle speed is approximately 15.0 r/s.
