System Overview Beginning in 1982 for the Spider, and 1981 for the GTV/6, Alfa adopted Bosch L-Jetronic fuel injection. The heart of this system is the airflow meter, which measures the amount of air being required by the engine. Hence the name L-Jetronic; the "L" stands for "luft", the German word for air.
LJetronic
The old Bosch L-Jetronic system is an analog fuel injection system. This means it has no software to chip, flash, or reprogram. It can not take advantage of the mass air flow conversion kits out there as they only work on digital systems. With an old analog system like L-Jetronic, it's all in the hardware.

The L-Jetronic is an electronically controlled fuel injection system which has the advantage of direct air flow sensing. It injects intermittently into the intake ports. The task of a fuel injection system is to supply precise amount of fuel to the combustion chamber at that particular moment.

The L-Jetronic is an electronically controlled fuel-injection system which injects fuel intermittently into the intake manifold. In North America it is equipped with an oxygen sensor (Lambda sond) to monitor the emission. The electronic module to which all switches, sensors and injectors are connected is called an ECU (electronic control unit).

BOSCH L-JETRONIC FUEL INJECTION IDLE ADJUSTMENT, DIAGNOSTIC AND TUNE UP PAGE for USA models of Alfa Romeo Spiders 1982-1989. I need to give a BIG thanks! to Eric Russell for providing us with this page.. * Fuel Pressure in the L-Jetronic system is quite critical. A fuel pressure problem can cause about every possible problem you can think of.
KJetronic Fuel Injection System
A physicist, Knapp had been one of the key members of this pioneering project to use electronics to control fuel injection. He had been assigned the task of developing the first prototypes in 1959. For this purpose, Bosch bought a Mercedes-Benz 300 as a company car and converted it into a test vehicle for electronic gasoline-injection systems.

K-Jetronic Operation: In fuel injection systems of Bosch L-Jetronic type, the volume of air drawn in by the engine is measured. Each cylinder has its own independent injector. An additional air slide-valve bypasses the throttle butterfly stub pipe and controls the additional air volume required when the air is still cold.

Its last iteration, KE-Jetronic (also known as CIS-E or "Continuous Injection System-Electronic"), designated the addition of electronic control for emissions and fuel economy compliance in 1985, before Bosch's digitally computerized LH-Jetronic made KE-Jet obsolete in 1993.

L-Jetronic. The Bosch L-Jetronic (also called AFC=Air Flow Controlled fuel injection) was put into US-spec Type 4s in the last model year (1974). While new carburated engines were used in the European markets, VW adapted the L-Jetronic for the Type 4 in the US due to more stringent emissions and fuel consumption regulations.

The primary purpose of the fuel-injection system is to provide the engine with an air/fuel mixture which is best suited to the prevailing operating state. Over the years,. - Continuous fuel injection 1973 L-Jetronic - Electronic multi-point injection system (initially analog, later digital technology) - Intermittent fuel injection
KJetronic Fuel Injection System
In more elaborate terms, KJet is a Continuous Injection System (commonly called CIS), where unlike later L-Jetronic or "standard" Electronic Fuel Injection, the injectors do not pulse open and closed; once the system pressure is high enough they all inject a constant spray of fuel, in all cylinders at once, which is varied in volume by the syste.
