Mechanical Gasoline Fuel-Injection System with Lambda
Data from Bosch
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.
