What is KE Jetronic?

KE-Jetronic are the air-flow sensor, the actuator. which regulates the fuel distributor, the pressure regulator which keeps the primary pressure constant and performs a specific shut-off function when the engine is stopped, and the electronic control unit.

How do you adjust K Jetronic fuel injection?

For early model cars using the K-jet (mechanical fuel injection) system, mixture adjustment is quite simple. A 3mm allen wrench is necessary to access the adjusting screw. Turning this screw to the right richens the mixture while turning it left leans it.

How does K jet work?

An air enters to the air filter, then it enters into the engine cylinders through the air flow sensor and throttle valve. Therefore, the rotary-type fuel pump with electric drive supplies fuel from the tank. The fuel enters to the fuel accumulator through the filter.

How does a Bosch fuel distributor work?

The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure.

Is K-Jetronic reliable?

All in all, K-jet is a pretty reliable system. Most of its problems are created by people who don’t know how to work on it. I would replace all of the boots and air lines you can and go from there.

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).

How does a warm up regulator work?

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. The Bimetal spring is heated in the process.

How does Bosch K-Jetronic work?

The injection valves of the K-Jetronic work purely mechanically from an opening pressure of 3.3 bar. The amount supplied by the control piston pushes the valve needle open more or less and leads to a rattling noise. The valve needle vibrates in its seat due to the fuel flowing past.

What is mechanical fuel injection?

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.

What is sequential injection and group injection?

Sequential fuel injection, also called sequential port fuel injection (SPFI) or timed injection, is a type of multiport injection. Though basic MPFI employs multiple injectors, they all spray their fuel at the same time or in groups.
