KJetronic
KJetronic, also known as Continuous Injection (CI) or simply "Jetronic," is a mechanical fuel injection system developed by Bosch. It was a significant advancement in automotive engine management, offering improvements in fuel efficiency and emissions control compared to carburetors. Introduced in the late 1970s, KJetronic was widely adopted by European automakers, particularly Volkswagen, Audi, Mercedes-Benz, and Porsche, throughout the 1980s and into the early 1990s.
The system operates on the principle of continuously injecting fuel into the intake manifold, upstream of the
Unlike later electronic fuel injection systems, KJetronic relies on purely mechanical and hydraulic principles. There is
