Bosch K-Jetronic Fuel Injection
Since their introduction, the Jetronic fuel
injection systems have proved themselves millions of times over under the harsh
conditions of everyday driving. This success is a result of the advantages
which fuel injection can offer when considering today's demands for economy,
performance, and cleaner exhausts. The K-Jetronic is a mechanical system in
which the fuel is continuously metered in accordance with the amount of air
drawn in by the engine. Using the Lambda sensor together with additional
equipment for the Lambda closed-loop control facility, the K-Jetronic can
already comply today with the exhaust-gas regulations of tomorrow. The
construction and principle of operation of the K-Jetronic is dealt with in this
Technical Instruction manual.
- It must be stressed that the implementation of
this system by Volvo on many of its cars, involves some modifications,
according to car model, engine, year and country of issue.
