“LE JETRONIC” ELECTRONIC FUEL
INJECTION SYSTEM
“LE Jetronic” system
The “LE Jetronic” IS a fuel injectiorl system which injects Intermittently petrol, at low pressure, into the inlet rnanifold
The main characteristic of the device IS to rneter drrectly 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 quantrty 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:
No.
