● Air density decreases as altitude or ambient
temperature increase. As a result of this, the
engine’s maximum output, the quality of the
exhaust gas, the temperature level and, in
extreme cases, starting behaviour, are im-
peded. Under transient conditions, the en-
gine can be used at altitudes up to 1000 m
and temperatures up to 30 °C. If the engine
is to operate under more severe conditions
(at higher altitudes or temperatures), it will
be necessary to reduce the injected fuel
quantity and thus, engine power.
● If you have any doubts about engine opera-
tion under these or similar conditions, ask
your engine or equipment supplier whether
the engine has been derated in the interests
of reliability, service life and exhaust gas
quality (smoke). Otherwise contact DEUTZ
SERVICE.
