The final car to use K-Jetronic was the 1994 Porsche 911 Turbo 3.6. Fuel is pumped from the tank to a large control valve called a fuel distributor, which divides the single fuel supply line from the tank into smaller lines, one for each injector.
From 1975 onward they used the K-Jetronic mechanical fuel injection system, a less complicated system that proved to be much more reliable in the long run with injectors costing significantly less than those used on the D-Jetronic system. The W116 equipped with the K-Jetronic system used a cast-iron fuel distributor which can be prone to rust ...
Continuously injecting mechanical MPI system Bosch K-Jetronic (ca. 1980s) The part on the right with red fuel lines coming out of it is the fuel distributor; the part on the left is a vacuum-driven piston used for determining the amount of air currently sucked into the engine
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 ...
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 ...
US models sold from 1976 through 1979 used the Bosch K Jetronic system, an entirely mechanical fuel injection system. From 1974, the front and rear bumpers were dramatically lengthened, by 8 inches (203 mm) on each end, to comply with the U.S. National Highway Traffic Safety Administration regulations that mandated no damage at an impact of 5 ...
BxxET - K-Jetronic turbo; B2xxET - Motronic controlled electronic fuel injection, turbo. F - low compression (9.8:1 on B230F, 9.5:1 on B280F, 10.0:1 on B234F and 10.7:1 on B204F), US/Europe version (F for Federal) with catalytic converter. Europe/APAC version, fuel injected (usually LH Jetronic or Bendix Regina) K - single jet type carburetor ...
The B23F used LH-Jetronic system and catalytic converter. All early 1983 B23F engines had the same compression ratio as the 1983 B23E, but, due to Chrysler ignition system usage, provided only 107 hp. After the switch to a Bosch distributor and coil, horsepower went up to 114 hp for the high compression B23F.
