New 1000 Serie » Altitude

If the naturally aspirated engine is lo 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.
