How Car Parts Work LJetronic Fuel Injection System
L-Jetronic System - Fuel Flow n Fuel is pumped up to fuel rail and excess returned to tank n Because so much fuel is circulated, filter is quite large. n Fuel lines are at high pressure (> 35psi), use BMW factory hose for replacement n Inspect lines regularly, fuel under pressure can cause LARGE fire. 1 Fuel Tank 2 Fuel Pump w/ Check Valve 3.

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.

L-Jetronic Fuel Injection 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

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. Contents

For those not familiar with Bosch L-Jetronic fuel injection you may want to start with L Jetronic Seminar in PDF format. This was a Microsoft Powerpoint document, presented at the 1999 E12 Fall Fest in Virginia Beach, VA.. A complete electrical diagram of the 528i fuel injection system is available here as an Adobe Acrobat PDF document. If.

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.

Benefits of Jetronic. The move from mechanical injection and carbs to electronic fuel injection was a matter of necessity. Carbs were a good, cheap solution, but far from the most efficient one. Your average carb was more than likely dealing with lag, and feeding an unstable mixture to the engine.

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 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.
LJetronic
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.

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.

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).
