PG
Required power PM = PG x fS x fH x fT
Power demand of the driven machine
P = 16.5 kW G
at 30 °C at 1300 m altitude above sea level, safety reserve capacity 5%
fS = 1.05 · fH = 1.14 · fT = 1.01
PM = 16.5 x 1.05 x 1.14 x 1.01 = 20 kW

SINGLE-CYLINDER-DIESEL ENGINES
Do not always choose the highest number of revolutions; a lower number of revolutions increases the maintenance intervals and the service life, and noise. In case of long-term operation of more than 1500 service hours per year, the number of revolutions should not exceed 2600 rpm.
The power demand of the driven machine often cannot be determined exactly, therefore, allowance must be made for safety reserve capacities, as well as for altitude and ambient temperature, if they differ from the standard.(ISO 3046-1, 100 m above sea level, +25 °C, 30% relative humidity)DIN ( ISO 1585 / 1000 mbar, +25 °C)
