What is the difference between K Jetronic and KE-Jetronic?

What is the difference between K Jetronic and KE-Jetronic?

KE-Jetronic is a combined mechanical-electronic gas injection control system with a closed-loop lambda control. As can be inferred, the essential difference between K-Jetronic i KE-Jetronic The system has an encoder and a control unit that processes the data received from the encoder.

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. As each plunger drops, it exposes a suction valve, where fuel is drawn through towards the injectors.

How does a mechanical fuel injector work?

Mechanical fuel injection works with a simple throttle-controlled air valve and a fuel pump, usually running at one-half engine speed. After pulling fuel from a vented fuel tank, the fuel is delivered through a barrel valve that controls the amount of fuel with the position of the air valve.

What are the advantages of electronic fuel injection?

Since EFI engines deliver air and fuel with better accuracy than a carburetor engine, they generally produce fewer emissions to go along with the improvement in fuel efficiency. Atomization of fuel also helps burn the fuel more completely.

How does Bosch fuel injection work?

Bosch K Jetronic With these systems, the fuel is delivered in a conventional manner from the fuel tank, via a rear mounted fuel pump, up to the fuel distribution unit (often known as the metering head) in the engine bay. It is delivered at a regulated pressure and any excess fuel is returned to the tank.

What’s the difference between fuel injection and EFi?

EFi stands for Electronic Fuel injection (EFi) whereas MPFi or MPi stands for Multi-Point Fuel injection and GDi stands for Gasoline Direct Injection. Thus, there is a fundamental difference between the earlier generation carburetor & newer generation Fuel Injection (EFi) system.

How does diesel mechanical fuel injection work?

In most diesel engines, fuel injectors are mounted in the engine’s cylinder head(s), and the tip or nozzle of the injector sprays directly into the combustion chamber. Fuel is fed to the injectors by a port-controlled distributor; this mechanical device controls the timing and quantity of fuel going to each injector.

Does Fuel Injection increase horsepower?

The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.

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.

Who is the inventor of Jetronic manifold injection?

Jetronic is a trade name of a manifold injection technology for automotive petrol engines, developed and marketed by Robert Bosch GmbH from the 1960s onwards. Bosch licensed the concept to many automobile manufacturers. There are several variations of the technology offering technological development and refinement.

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.

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).
