Exhaust Emission Control by Fuel Injection: The VW 1600 with Electronically Controlled Fuel Injection System

The 1968 models of the VW 1600 sedan for the U. S. market are equipped with an electronically controlled fuel injection system. These vehicles comply with existing exhaust emission standards.

Engine fuel requirements for constant operating conditions were determined by exhaust gas analysis. The test results furnished the basis for fuel metering by means of an electronic control unit. Deceleration fuel shutoff and closely controlled mixture enrichment for cold starting, warmup and full load ensure low emissions and good driving characteristics.

Push-button checks for all the major circuit functions can be carried out with a special checking instrument.
