In position 2 the oilhas been pumped up from the fuel pump, while in position 3the fuel valve has lifted, and the oil is being injected intothe cylinder. The blast of air forces the oil through speciallyshaped passages, which are usually curved, or of Lregularform, and the mixture is given a spiral motion, the heavierparticles of oil being throw n against the sides of the passageso that complete pulverisation takes place. The pulveriseris entirely cleared of oil with each injection, which in rever-sible marine engines is a considerable advantage, and it.
