The M110.98x and .99x engines are fuel-injected engines, with Bosch D-Jetronic up to the .983 and K-Jetronic from the .984. All M110 engines have a displacement of 2.7 L; 167.6 cu in (2,746 cc) and a bore and stroke of 86 mm × 78.8 mm (3.39 in × 3.10 in). Firing order is 1-5-3-6-2-4. Amount of coolant in the radiator was 11 litres (2.9 US gal ...
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 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 ...
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 Europe, the 2.8 was produced with carburetor 132 PS (97 kW; 130 bhp), mechanical fuel injection (Bosch K-Jetronic, 160 PS (118 kW; 158 bhp), and electronic injection (Ford EEC-IV, 150 PS (110 kW; 148 bhp)). Electronic injection only featured on the 2.8 Granada models for one year before being replaced with the 2.9 unit.
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 ...
The sporting model XR4i utilized the 2.8 engine with mechanical fuel injection (Bosch K Jetronic) coupled to rear-wheel drive (1983–1985) and to four-wheel-drive as XR4x4 (1985–1987). There were visual differences and alterations between the XR4i and XR4x4, such as coloured bumpers, the removal of the 'biplane' rear wing and alloy wheels as ...
