A New Low Pressure Single Point Gasoline Injection System 850293

The paper describes the second generation of Bosch single point injection systems. It is a low cost system and specifically designed for closed loop control.
The system uses a fuel pressure of 1 bar (14.5 psi) and will apply throttle angle/engine speed control. This type of control was already used in the very beginning of the fuel injection era but is now updated by closed loop and adaptive memory control.
The throttle body, completely new designed as a module for most installation requirements, as well as characteristics of other new components such as ball type injector, throttle valve potentiometer and electric fuel pump will be described.
Realized functions will be shown and test results on engines and cars will be given.
