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.

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.

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.

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.
KJetronic Fuel Injection System
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.

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.

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.

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.

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).

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.

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.
KJetronic Fuel Injection System
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.
How Car Parts Work LJetronic Fuel Injection System
Electronic fuel injection is a system of electronic inputs and mechanical actions. On the FIAT system, the electronic inputs are water temperature, air temperature, engine speed, exhaust gases, and throttle position.
