Electronic Fuel Injection

The paper provides a brief description of gasoline fuel injection principles and the resulting features both for multipoint and singlepoint systems. The function of different Bosch-systems and components were explained. The paper then deals with some new developments, i.e. a new fuel injector enabling new low pressure single point injection systems, air shrouding of fuel injectors and a complete new system, the KE-Jetronic, an electronically controlled continuously injecting multipoint system.
