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.
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 KE-Jetronic 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.
What is motronic engine management system?
Motronic engine management systems use electronics to precisely monitor and control every aspect of engine operation, thereby improving efficiency, power, and driveability, while at the same time reducing fuel con- sumption and tailpipe emissions.
What cars use Jetronic?
K-Jetronic debuted in the 1973.5 Porsche 911T in January 1973, and was later installed into a number of Porsche, Volkswagen, Audi, BMW, Mercedes-Benz, Rolls-Royce, Bentley, Lotus, Ferrari, Peugeot, Nissan, Renault, Volvo, Saab, TVR and Ford automobiles.
What are the advantages of electronic fuel injection?
EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.
What is VW motronic?
Motronic systems combine ignition timing with knock control, fuel injection, fuel economy and emissions control. Combining all these functions into a single control unit allows adaptive strategies to control idle speed, ignition timing and fuel injection, depending upon actual operating conditions.
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.
What does a motronic do?
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 are the disadvantages of electronic fuel injection?
Disadvantages of Electronic Fuel Injection System
- High maintenance cost.
- Difficulty in servicing.
- Possibility of malfunction of some sensors.
