Ignition and gasoline-injection systems from Bosch
More than a century of system expertise
Renowned vehicle manufacturers rely on Bosch as original equipment
supplier and thus form the basis for a fruitful replacement
parts business.
In addition to the full range of more than 10,000 items for gasolineinjection
systems, Bosch also supplies the aftermarket and workshop
sector with the appropriate replacement and wear parts.
1902 Delivery of the first high-voltage magneto and the first spark
plug
1910 Separation of ignition distributor and high-voltage source
1925 Presentation of battery-ignition system by Robert Bosch
GmbH
1951 Presentation of Bosch gasoline-injection system at the
Frankfurt Motor Show
L-Jetronic components
1967 First emission legislation in the USA
Introduction of the first electronic injection system:
The D-Jetronic controlled by intake-manifold pressure.
1973 Energy crisis – fuel consumption becomes the focus of
development efforts
Market launch of the L-Jetronic with air-flow sensor and the
K-Jetronic with mechanical-hydraulic control – this was also
an air-flow sensing system.
1976 Bosch invents the Lambda sensor, thus paving the way for the
closed-loop-controlled catalytic converter.
1979 Motronic market launch
The unique feature of this system was the digital processing
of a wide range of engine functions. It combines the
L-Jetronic principle with electronic map-controlled ignition.
The first microprocessor to be fitted in a motor vehicle.
KE-Jetronic components
1981 LH-Jetronic market launch
Instead of a flap-type air-flow sensor, the basic L-Jetronic
system was equipped with a hot-wire air-mass meter and
marketed for the first time as LH-Jetronic.
