KJetronic Fuel Injection System
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).

The Bosch L-Jetronic fuel injection system used in the Porsche 912E is often referred to as the Air Flow Controlled or AFC fuel injection system. Originally, Volkswagen adapted the L-Jetronic for the Type 4 air cooled 411 engines sold in the United States due to more stringent emissions and fuel consumption regulations.

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.

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.

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 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 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

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.

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.

Electronically controlled mechanical fuel injection. The engine control unit (ECU) may be either analog or digital, and the system may or may not have closed-loop lambda control. The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.
