LH Jetronic 2.2 fuel system (760 Turbo)
The LH-Jetronic 2.2 fuel injection system is all-electronic and is microprocessor-controlled. It can continually compensate for variations in
engine load, speed and temperature to give the best economy and power. The most unique feature of the system is an air mass meter that
measures the mass of the inducted air instead of the volume. In this way the system can make instantaneous adjustments for changes in air
temperature or density, thus always assuring the best economy with the lowest-possible exhaust emissions.
Lambda-sond
TM
(oxygen sensor) System
This is an emission control system designed to reduce emissions and improve fuel economy. An oxygen sensor monitors the composition of
the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic unit. This adjusts the air-fuel ratio to provide
optimum conditions for combustion and efficient reduction of the three major pollutants (hydrocarbons, carbon monoxide and nitrous gases)
by a 3-way catalytic converter.

Catalytic Converter
This is a supplementary device in the exhaust system, designed to clean exhaust gases.
This device is mainly a container with a ceramic material insert, designed to let the exhaust gases pass through channels in the insert. The
