Present Status and Future Development of Gasoline Fuel Injection Systems for Passenger Cars

After a review on history, market, physical facts of fuel injection follows a short description of present systems. Influences on fuel consumption and emissions, including Lambda-control, are described. Some notes are given on the influence of injuction timing, single point injection, combination of fuel injection and ignition to a digital motor electronics. New development trends for less expensive and more effective systems are shown.
