What is the difference between K Jetronic and KE-Jetronic?
KE-Jetronic (1985–1993) The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.
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 Jetronic fuel injection 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 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 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 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.
What is common rail fuel injection system?
Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).
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.
What is motronic ECU?
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.
What is the main difference between Motronic and Jetronic engine?
How does Bosch Motronic work?
Are common rail diesels reliable?
The Common Rail Diesel (CRD) injection system is the most recent development to achieve ever more stringent diesel exhaust emission standards, but it is currently associated with widespread problems, including engine rattles, expensive injector and fuel pump failures, injector sticking, stalling problems and rapid …
Is port injection better than direct injection?
Port injection provides a better, more stable air/fuel mixture at lower engine speeds, which results in smoother operation upon startup. At higher rpm, direct injection provides a greater cooling effect, allowing for more power and less chance of knock.
How long do common rail diesels last?
The lifespan of a diesel fuel injector Diesel fuel injectors generally have a shorter lifespan than their predecessors, meaning they need to be replaced more frequently for optimal performance. The life expectancy of a good quality diesel fuel injector is around 150,000 kilometres.
