“LE Jetronic” system
The “LE Jetronic” is a fuel injection system whrch injects intermittently petrol, at low pressure, into the Inlet manrfold
The main characteristic of the device is to meter directly the air drawn In by the engine, which is the only reference
for the fuel quantity to be injected. The fuel metering is carried out by electro-magnetically triggered injectors. These
are under a constant fuel pressure.
The quantity of fuel injected depends on how long the injectors remain open. The duration of opening IS optimally
determined for each engine operating phase by an electronic control unit, from data supplied by various electric
sensors.
The “LE Jetronic” device is composed of:
