What is the difference between K-Jetronic and KE-Jetronic?
What is the difference between K-Jetronic and KE-Jetronic?
The main difference between the two types is that on the KE-Jetronic system all mixture corrections are controlled electronically by an electromagnetic pressure actuator incorporated in the fuel distributor.
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 a CIS system work?
On a CIS engine, the air intake lifts a plunger, and fuel is injected in varying quantities depending on the position of the plunger. The injectors are designed to hold pressure until the plunger is lifted, and the pressure is increased, causing the injectors to spray out – basically a controlled leak.
How does a fuel accumulator work?
Re: Exactly what does a Fuel Accumulator do? ( It retains fuel pressure in the system to aid hot starting (reduces fuel vaporisation in the fuel lines), it doesn’t influence cold starts as the pressure does stay that long. It also smooths the pulses of the fuel pump (like a damper).
What is CIS fuel system?
CIS, or continuous injection system, is a method of fuel injection which is very different from modern cars. The air intake stream controls the volume of fuel, the coolant temperature dictates when to use oxygen sensor regulation, and the oxygen sensor regulation further controls the volume of fuel.
What is a CIS injector?
CIS injectors *are* wear items. They are spring loaded, and have specific opening and closing pressure ranges. The springs wear over time, and injectors can leak, or flow at different rates. Cleaning can improve a used injectors performance, but at some point you’ll just have really clean worn out injectors.
How does a Bosch Mono Jetronic work when cold?
When cold (ATS and CTS the same value, and no lambda switching) the ECU will juggle throttle position and fuel to give a slightly fast tickover. On the mono-jetronic the ignition is totally separate from the injection (so no MAP sensor), but there is the vacuum advance to the distributor ot advance the spark on light throttle.
How is Mono Jetronic different from other fuel injection systems?
In the US, this kind of single-point injection was marketed as ‘throttle body injection’ (TBI, by GM), or ‘central fuel injection’ (CFI, by Ford). Mono-Jetronic is different from all other known single-point systems, in that it only relies on a throttle position sensor for judging the engine load.
Is there a MAP sensor on Bosch Mono Jetronic?
On the mono-jetronic the ignition is totally separate from the injection (so no MAP sensor), but there is the vacuum advance to the distributor ot advance the spark on light throttle. Check the advance cartridge – it fails and you get very flat performance and poor economy.
Which is Mono Jetronic ignition and starter switch?
14 ignition and starter switch illustrate their Mono-Jetronic single-point to the injector. By virtue of its low output pressure, this pump is both light and very economical to manufacture, many of its components being of plastics.
