Reply to: KE-jetronic closed loop

According to the Bosch Automotive Handbook, the KE-Jetronic uses an 
'electrohydraulic pressure actuator' which controls the system fuel 
pressure.  The KE also has an ECU which controls this device from the 
outputs of various sensors, the O2 sensor being one of them.

Hello everyone.  A recent discusion has prompted me to ask how an oxygen 
sensor feeds back on a mechanical injection system?  Does it contol a 
fuel pump relay that alters the pressure?  It makes sense how feedback 
works on an electronic system by altering the pulse width of the 
injectors.  But there is no pulse width in a CIS system.

Thanks to anyone who can educate me
