The M110.984 was the first engine with the new Bosch K-Jetronic injection. This system is mechanical. The air that is taken in is weighed to then determine the amount of fuel to inject. Power output: 130 kW (177 PS; 174 hp) at 6000 rpm up to April 1978; 136 kW (185 PS; 182 hp) at 5800 rpm from April 1978. Applications: 1975-1981 280E (W123)
Bosch built this system under licence, and marketed it from 1967 as the D-Jetronic. [21] In 1973, Bosch introduced their first self-developed multi-point injection systems, the electronic L-Jetronic, and the mechanical, unpowered K-Jetronic. [23] Their fully digital Motronic system was introduced in 1979. It found widespread use in German ...
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. The final car to use K-Jetronic was the 1994 Porsche 911 Turbo 3.6.
K-Jetronic was a mechanical injection system, using a plunger actuated by the intake manifold pressure which then controlled the fuel flow to the injectors. [55] Also in 1974, Bosch introduced the L-Jetronic system, a pulsed flow system which used an air flow meter to calculate the amount of fuel required. L-Jetronic was widely adopted on ...
Bosch developed their D-Jetronic (D for Druckfühlergesteuert, German for "pressure-sensor-controlled"), from the Electrojector, which was first used on the VW 1600TL/E in 1967. This was a speed/density system, using engine speed and intake manifold air density to calculate "air mass" flow rate and thus fuel requirements.
By the mid-1980s, JECS were using LH-Jetronic, and the new Bosch hotwire mass airflow meter. The early JECS LH-Jetronic systems were based on a Motorola 6800 architecture, using many Hitachi components. The earliest hotwire meters were still from Germany, but by the end of the 1980s all of the system components (pumps, sensors, injectors, ECU ...
In the mid-1980s, Lucas developed the 13CU system by revising the Bosch L-Jetronic system and adding an electronic diagnostics capability to comply with California Air Resources Board requirements. The design of the 13CU also deviated from the original L-Jetronic design in that it used a hot-wire air mass sensor rather than the Jetronic's ...
