Nitrous oxide wet systems use fogger nozzles to inject the nitrous and fuel into the engine. The fogger does two jobs. First it mixes the nitrous and fuel together and secondly it atomises the mix as it injects it. The fogger has two inputs that come from the solenoids. So that when the solenoids are energised the nitrous and the fuel flow through them to the fogger. Most systems have a single fogger mounted in the throttle body but some systems are 'multi port'. A multiport system will have as many foggers as there are cylinders, so a V6 engine will have 6 foggers... one in each branch of the intake manifold. It is important to mix the nitrous and fuel in the correct ratios and for this we use jets. The jets are tiny brass orifaces that sit in between the feed line to the fogger and the fogger itself. The sizes of the holes in these orifaces determines the ratio of nitrous to fuel that is mixed and injected and thus has a bearing on the overall air/fuel ratio of the intake charge. A nitrous jet online calculator appears at the foot of this page for you to play with!
