Exhaust Emission Systems: Description: Notes
NOTE:
1970-71 models use Bosch Electronic Fuel Injection only for emission control. For additional information, see Bosch Electronic Fuel Injection in CARBURETION Section.
In addition to changes to the electronic fuel injection, the Porsche 914 incorporates a device to supply additional air for combustion on engine overrun (deceleration) at high engine speed, and a temperature and load dependent air intake preheating system.
