Environmental care
There are many examples of environmental care within the Volvo field of
activity. We use a chlorine free refrigerant in our climate control systems
which is totally harmless to the ozone layer and which has only a very
limited effect on the greenhouse effect. Asbestos-free brakes, engines with
catalytic converters and compressed natural gas (CNG) drive are other
examples of what we at Volvo Car Corporation are doing for the environment.
Our specific services are also of importance to the environment, such as
using Volvo Genuine parts, maintaining ignition and fuel systems, and
other measures that directly reduce exhaust emission. We would also like to
point out the care taken by our Volvo workshops in regards to handling
environmentally dangerous substances.
Catalytic converter
The catalytic converter is an additional part of the exhaust system. Its
purpose is to purify exhaust. The converter primarily consists of a housing
with two monoliths that are designed so that the exhaust gases pass through
a honeycomb of channels. The channel walls are lined with a thin layer of
platinum, rhodium and palladium. These metals act as catalysts, i.e. they
participate in and accelerate a chemical reaction without being used up
themselves.
Lambda-sond TM (heated oxygen sensor, petrol engines only)
The lambda sensor is part of a management system intended to reduce
emissions and improve fuel economy. An oxygen sensor monitors the
oxygen content of the exhaust gases leaving the engine. These values are
fed into an electronic system that continuously controls the injectors. The
ratio of air to fuel is continuously adjusted. These adjustments create optimal
conditions for efficient combustion, and together with the three-way catalytic
converter reduce harmful emissions (hydrocarbons, carbon monoxide and
nitrous oxides).
Official fuel consumption figures are based on a standard driving cycle;
EU directive 80/1268 comb. Fuel consumption figures can be altered if the car is equipped
with extra options which affect car weight. The manner in which the car is driven and
other non-technical factors can affect fuel consumption.
