Turbocharged engines

Because of the power characteristics of the turbocharged engine it is necessary to maintain a high engine
speed when you climb a gradient. To ensure that the engine is not overloaded at low engine speeds engage
a lower gear.

Altitude

If the naturally aspirated engine is to run at an altitude above 600 m (2,000 ft), the fuel delivery can be changed
to reduce fuel consumption and smoke. Perkins can give the percentage of fuel reduction necessary if details
of engine application and ambient conditions are given. Information for turbocharged engines can be obtained
from Perkins. Changes to the settings of the fuel injection pump must be made by a Perkins distributor or by
an approved distributor for the fuel injection pump.
