L-JETRONIC - ELECTRONIC PETROL INJECTION SYSTEM WITH AIR INTAKE MEASUREMENT

L-JETRONIC - ELEKTRONISCHES BENZINEINSPRITZSYSTEM MIT LUFTMENGENMESSUNG

THE L-JETRONIC IS AN INTERMITTENT OPERATING DEVICE WITH LOW PRESSURE SUCTION PIPE INJECTION, BY WHICH THE QUANTITY OF AIR DRAWN INTO THE ENGINE IS DIRECTLY MEASURED AND ACTS AS THE MAJOR CONTROL FOR THE QUANTITY OF FUEL SUPPLIED. THE FUEL IS MEASURED BY MEANS OF ELECTRO-MAGNETICALLY CONTROLLED INJECTION VALVES. THEY REMAIN UNDER CONSTANT FUEL PRESSURE AND THE LENGTH OF TIME FOR WHICH THEY REMAIN OPEN, PROPORTIONAL TO THE FUEL INTAKE, IS CONTROLLED ELECTRONICALLY BY OPTIMAL INFORMATION FROM DIFFERENT ELECTRICAL TRANSMITTERS FOR EVERY OPERATING CONDITION. THESE INCLUDE CHOKE SWITCH, IDLING AND FULL LOAD SIGNALS, AND THE COLD START VALVE, WHICH IS OPERATED FOR ENGINE TEMPERATURES OF BELOW -15 DEGREES C BY MEANS OF A TEMPERATURE-DEPENDENT THERMAL SWITCH TO PROVIDE A FUEL ENRICHED MIXTURE. THE CONSTRUCTION AND THE OPERATING METHODS OF THE L-JETRONIC ARE PRECISELY DESCRIBED. THE ALREADY LOW POLLUTANT VALUE OF THE EXHAUST GASES CAN BE FURTHER REDUCED BY THE INCLUSION OF A CATALIZER AND THE OPERATION OF THE ENGINE UNDER PRECISELY MEASURED AIR - FUEL BEHAVIOUR.
