Engine Selection Advise


You must consider the following when selecting an engine:

Application:    e.g. water pump

Hp or kW required    e.g. 20 hp

Speed    e.g. 2500 rpm

Direct coupled or v-belt    e.g. direct coupled by flexible coupling

Ambient conditions    e.g. up to 40c , 30% humidity

Site conditions    e.g. under cover on farm site

Duty – continuous or intermittent    e.g. continuous 2500 hrs per year

Other factors    e.g. Side loads, vibration, electrics, maintenance and service plan, noise levels, shock loads, exhaust emissions etc.


Standard conditions:    20°c ambient temperature, 30% relative humidity at 100 mtrs altitude.


Gross intermittent rating:    1 hr rating based on engine without cooling fan, air cleaner, muffler, but with

alternator idling.


Net intermittent rating:    1 hr rating based on engine with standard cooling fan, air cleaner, muffler and

alternator, fitted to engine


Net continuous rating:    Continuous output based on engine with standard cooling fan, air cleaner,

Muffler and alternator fitted.


De-rating:    Refer to DPS. Allowance for changes to standard conditions being ambient temperature, relative humidity and altitude.


Transmission Factors:    Allowance for power losses in the transmission system e.g. Belt and pulley

losses, flexible coupling losses, gearbox transmission losses etc.
