Alfa Romeo F1 Staff Stake technical director Jan Monchaux lately answered questions in regards to the crew’s use of Marelli’s modern new “micro carry” gasoline pumps within the gasoline tank of the crew’s F1 race automobiles, the place he described the advantages of this know-how in a racing software.
Q: Why is it essential for these pumps to be within the gasoline tank?
Jan Monchaux: We begin the race with greater than 100 kilos (of gasoline) and slowly and certainly the gasoline (degree) drops down. You could successfully and continually be certain that the engine receives the gasoline that it requests.
In some unspecified time in the future, when the gasoline degree is comparatively low, relying on how the motive force can be alongside the circuit, like braking very exhausting or accelerating very hear and taking some corners very, in a short time, you’ll have the remaining gasoline sloshing round and doubtlessly sooner or later the engine won’t be fed with the gasoline anymore.
Q: How do these pumps keep away from that drawback?
Jan Monchaux: The gasoline can be pushed right into a nook (of the automobile’s gasoline tank) and the engine won’t get it anymore. With these micro carry pumps we’ve, that are in very particular positions within the gasoline tank, we’ll be certain that these are added within the geometry as a result of we’ve a really advanced buffering system within the gasoline cell, we ensure that even once we go nearly to the tip of the gasoline cell, on the gasoline tank degree, that via these pumps we ensure that the quantity of gasoline the engine requests is at all times there. It is rather essential for us. If it doesn’t work, the engine stops!
Q: What are the advantages of the Marelli gasoline pump?
Jan Monchaux: The benefit of these new pumps for us is the dimensions. It’s smaller, it’s a weight saving, which for us is essential.
There are additionally some traits associated to the pump itself which permits us to be (extra simply) inside what the FIA expects. As a result of we’ve obtained some laws on the quantity of gasoline, fairly advanced methods on the quantity of gasoline we’re allowed to ingest continually within the engine.
You at all times wish to be on the restrict of what’s allowed. This pump, so far as I imagine, helps us to be so much nearer to what’s allowed. It permits us significantly better management of the gasoline.
