EFFECTS OF ALTITUDE AND
TEMPERATURE ON ENGINE PERFORMANCE
Altitude, fuel temperature, air temperature, and humidity
may affect engine performance. As a general rule,
atmospheric changes will usually cause a decrease in
engine power by the percentages shown in chart below.
ATMOSPHERIC CHANGE
% POWER
DECREASE
Fuel Temperature Rise of 1C (1.8F)
above 40C (104F) ........................................................................ 0.29
Air Temperature Rise of 5.5C (10F)
above 25C (77F) .......................................................................... 0.50
Naturally Aspirated Engines:
Altitude Rise of 300 m (1000 ft) above
180 m (600 ft) ................................................................................. 3.00
Turbocharged Engines:
Altitude Rise of 300 m (1000 ft) above
183 m (600 ft) ................................................................................. 0.50
Relative Humidity Rise of 10% above 0% ...................................... 0.07
If engine requires recalibration of fuel injection pump for
acceptable performance at higher elevation, contact your
local authorized fuel injection pump repair station for
service.
