Louvred air suction vents
Each engine requires about 6.1 m3 (215 cu.ft.) of air per kW (4.5 m3/HP) per
hour . For proper functioning, the velocity of the air taken in, should not
be higher than 3 m/sec (9.85 ft/sec). The design of the openings of the VETUS
air suction vents has been based on these facts.
Apart from the necessary air for combustion, each engine also needs air for
dissipation of heat, radiated by the engine. The required quantity of this
ventilation air is about the same as that of the combustion air, but it should
furthermore be allowed to leave the engine room as well. Please, make sure of
this, when designing the engine room lay-out! The numbers of the models in the
drawings indicate the horse power ratio for wich these air vents have been
developed. In other words, in the case of a twin engine installation of 44 kW
(60 HP) each (120 HP in total), 2 louvred air suction vents type 125 can be
chosen (1 x Port + 1 x SB), or 4 pcs.
of the type 60 (2 x Port + 2 x SB).
) In order to burn 1 kg of fuel (approx. 1.18 litres) a volume of 16 kg of air is needed (approx. 12.4 m3 at 1 atmosphere).
Use the air suction vent as a template to mark off the required hole size.
