LH Jetronic fuel system
The LH-Jetronic fuel injection system is all-electronic and 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.

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 channel walls are covered by a thin layer of platinum-palladium. These
metals act as catalysts, permitting a chemical action to occur without actually taking part in it.
The emission (CO, HC, NOx) content will increase if the catalytic converter is damaged. Lambda-sond
equipped vehicles use Catalytic Converters containing platinum and rhodium.
