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.
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 ...
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 ...
The 3.0 L (2,960 cc) M104 featured KE-Jetronic fuel injection, cylinder specific ignition-timing, variable valve timing and under-piston cooling jets. Specifications Engine power @ 6400 rpm or 6300 (300E-24 300S 300SL-24): 217 to 228 hp (162 to 170 kW; 220 to 231 PS) (without catalytic converter ).version R129 300SL-24 has 170 kW (231 PS; 228 ...
The 190 E (E for Einspritzung, or Fuel Injection) model uses the Bosch KE-Jetronic Multi-Point Fuel Injection to meter fuel instead of the carburetor of 190 models. Thanks to their fuel injection system and larger intake and exhaust valves, 190 E models made more power than non-fuel injected 190 models. [ 3 ]
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.
A 2.0 L multi-point fuel-injected (KE-Jetronic) variation of the M102.921. An "E" was added to the model of the vehicle (standing for "einspritzung", the German word for fuel injection). An "E" was added to the model of the vehicle (standing for "einspritzung", the German word for fuel injection).
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. By controlling both major systems in a single unit, many aspects of the engine's characteristics (such as power, fuel economy, drivability ...
