Repair Guides Bosch Ljetronic And Motronic Fuel Injection Systems Bosch Ljetronic And
L-jetronic is a Bosch-manufactured electronic fuel injection featured on many early 80's cars. The basic L-jetronic consists of a Fuel pump,Fuel filter, Fuel lines, Fuel regulator, Fuel injectors, Cold-start injector (Could be omitted on some L's), Thermo-time switch, Coolant temperature sensor, auxiliary air valve, throttle plate and an air-flow sensor (Flap type in analog L's discussed here).

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.

Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors,. Compared with L-Jetronic, the fuel injectors used by LE-Jetronic have a higher impedance. Three variants of LE-Jetronic exist: LE1, the initial version. LE2 (1984.

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.

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.
LJetronic
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.

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.

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. In 1990 Bosch Motronic fuel injection replaced L-Jetronic on the Spider and 164 models. While the general operating principles are the same, Motronic.
