What cars use Bosch k Jetronic?
K-Jetronic debuted in the 1973.5 Porsche 911T in January 1973, and was later installed into a number of Porsche, Volkswagen, Audi, BMW, Mercedes-Benz, Rolls-Royce, Bentley, Lotus, Ferrari, Peugeot, Nissan, Renault, Volvo, Saab, TVR and Ford automobiles.
What is the difference between D Jetronic and L Jetronic?
d-jet used manifold pressure as it’s primary input for engine load. L-jet used an air flow sensor (flapper valve style) which directly measured engine air consumption as its primary input combined with an engine rpm input from the ignition module.
How does lh Jetronic work?
Overview of L/LH-Jetronic Fuel Injection Systems In pulsed injection, all air entering the engine first flows through an air-mass meter. The air-mass meter measures the air, which indicates engine load, and converts that measurement into an electrical signal to the control unit (ECU).
What is KJET?
K-Jetronics is CIS, continuous/constant injection. it uses a mechanical ‘fuel distributor’ to adjust the fuel pressure according to the airflow, and the injectors always spray. Volvo abandoned K-Jet circa 1981 or 82 in favor of LH electronic injection.
How do you adjust K Jetronic fuel injection?
Remove one injector line from the top of the fuel distributor, and while looking into the injector port in the top of the fuel distributor turn the mixture adjustment screw clockwise until the port just starts to fill with fuel then turn the mixture screw 1/2 turn counter clockwise.
What is CIS fuel injection?
The continuous injection system (CIS) is so-called because, unlike many other fuel injection systems, the injectors do not open and close-they deliver fuel continuously. The main function of the fuel injectors is to atomize the continuous flow of fuel being supplied under pressure from the fuel distributor.
How does a mechanical fuel injector work?
Mechanical fuel injection works with a simple throttle-controlled air valve and a fuel pump, usually running at one-half engine speed. After pulling fuel from a vented fuel tank, the fuel is delivered through a barrel valve that controls the amount of fuel with the position of the air valve.
How does a warm up regulator work?
The Warm-up regulator ensures that the engine runs smoothly when looking for one cold start slowly getting warm. It is directly connected to the motor so that it can measure the motor temperature directly as a controlled variable. When the engine warms up, the bimetal spring bends back up.
What does a motronic do?
Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit.
