What is the difference between D Jetronic and L-Jetronic?
L-Jetronic used custom-designed integrated circuits, resulting in a simpler and more reliable engine control unit (ECU) than the D-Jetronic’s. L-Jetronic was used heavily in 1980s-era European cars, as well as BMW K-Series motorcycles.
What cars use Jetronic?
L-Jetronic was used heavily in 1980s-era European cars, as well as BMW K-Series motorcycles. 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.
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).
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.
How does Bosch mechanical fuel injection work?
Built in an age before electronic sensors and regulators, the MFI pump uses a series of mechanical ‘sensors’ to create an ever-changing fuel map based on throttle position, engine speed and barometric pressure.
How does Bosch motronic work?
The Motronic units have 2 injection outputs, and the injectors are arranged in 2 “banks” which fire once every two engine revolutions. In an example 4-cylinder engine, one output controls the injectors for cylinders 1 and 3, and the other controls 2 and 4.
How do you clean AK Jetronic injectors?
About all you can do is soak them in a bath of injector cleaner, B12 chemtool, or Seafoam. After that, blow them out as well as you can. Nothing to do on a CIS unless you have the big test jig to measure flow rate.
Is mechanical fuel injection Streetable?
Mechanical Fuel Injection Is Not Just for Race Cars Anymore Great horsepower or horrible driveability, your only options. Since its ’40s conception, mechanical fuel injection (MFI) was strictly reserved for race cars. Street cars need not apply.
Is mechanical fuel injection good?
On normally-aspirated engines, a properly set up mechanical fuel injection system provides instant throttle response, which makes the system great for racing applications.
What is the main difference between motronic and Jetronic engine?
As far as I can tell, the L-Jet and Motronic systems in the 75/164 (respectively) are very similar; air flap for measuring airflow, throttle position sensor, coolant temperature sensor, rpm, etc. It seems the only difference on the fuel side is the L-Jet is analog and the Motronic is digital.
