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 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 CIS injection?

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, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi). This system has no lambda loop or lambda control.

How does Bosch motronic work?

x was one of the first digital engine-management systems developed by Bosch. These early Motronic systems integrated the spark timing element with then-existing Jetronic fuel injection technology. If the engine is naturally aspirated, an air temperature sensor is located in the air flow meter to work out the air mass.

What is motronic control unit?

The Motronic control unit for CNG controls the mixture formation (air mass, injected CNG mass and time of the injection), ignition and exhaust-gas treatment. In bifuel systems, Motronic controls the engine operation with CNG and gasoline.

Who are the manufacturers of Jetronic fuel injection systems?

Licensing some of Bosch’s L-Jetronic concepts and technologies, Lucas, Hitachi Automotive Products, NipponDenso, and others produced similar fuel injection systems for Asian car manufacturers.

How is K-Jetronic different from pulsed injection systems?

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, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi ). The volume of air taken in by the engine is measured to determine the amount of fuel to inject.

How to troubleshoot D Jetronic Bosch fuel injection system?

Chapter 13 of D-Jetronic articles by Dr-DJet describes systematic fault finding (troubleshooting) and repair on your Bosch fuel injection system. Adjust valves, even if your workshop manager claims that your engine has hydraulic valve lifter Check all vacuum hoses and pipes for false air. Even D-Jetronic will fail with massive false air.

What is the function of KE-Jetronic fuel injection?

KE-Jetronic is a combined mechanical-electronic gas injection control system with a closed-loop lambda control. Its main function is to supply fuel to the engine depending on the amount of air that is sucked into the engine (the basic control variable).

Licensing some of Bosch’s L-Jetronic concepts and technologies, Lucas, Hitachi Automotive Products, NipponDenso, and others produced similar fuel injection systems for Asian car manufacturers.

How is the vacuum measured in Jetronic fuel injection?

D-Jetronic (1967–1979) Analogue fuel injection, ‘D’ is from German: “Druck” meaning pressure. Inlet manifold vacuum is measured using a pressure sensor located in, or connected to the intake manifold, in order to calculate the duration of fuel injection pulses.

Commonly called ‘Continuous Injection System (CIS) in the USA.
