Ferrari PU UPDATE (Spanish GP 2019)
Ferrari: two-metal alloy pistons make their debut in the two engine?
After two years of experimentation, Ferrari decided to bring the steel pistons to the track: thanks to the production in Addicting Manufacturing, weight would have been saved, reaching a stiffness and resistance to high temperatures higher than those of aluminum.
The question everyone asks is: why did Ferrari anticipate the debut of the second engine of the three cars awarded in the 2019 season at the Spanish GP? Mattia Binotto, Cavallino team principal, announced yesterday the decision that was made in the Racing Department ...
"In Spain there will be a new power unit anticipating the initial program that planned to introduce the second unit in Canada - explained Binotto - for this power unit Shell, in collaboration with the team, has developed a different oil that will guarantee better performance. We were able to bring these developments here only thanks to a great team effort that shows how much the whole team is pushing to catch up ”.
The goal is to close the gap that separates the SF90 from Mercedes, bringing a contribution to performance also from the mechanics and not only from the aerodynamic package that was approved for Montmelò with new, more loaded wings (front and rear), bearing in mind that Barcelona 10 more horses are worth a gain of 0 "13 on lap time, given that the Catalan track, despite what is being said, is quite sensitive to the power of the power units.
But what is the novelty that distinguishes this two motor of the Prancing Horse? The mouths in Maranello are sewn, but according to the few rumors that filter it would be time to debut the bi-metal alloy pistons able to withstand the greater stresses that there will be in the combustion chamber and thermal expansion without compromising the reliability .
So far the engineers driven by Corrado Iotti have exploited aluminum alloy pistons, while, after a couple of years of experimentation, the times for the use of those in steel alloy that had not been set aside, but have been developed on a parallel plane.
It is true that steel pistons have a higher specific weight than aluminum ones, but they also have a greater capacity to withstand deformations and temperatures.
Not only that, but thanks to the Addicting Manufacturing, that is the technology that allows to realize complex parts through special 3D metal-jet printers, it is now possible to create three-dimensional objects with a deposit of layers of dust composed of materials that would be complex to use in traditional fusion processes.
The steel alloy (the second element seems to be very innovative) would have allowed the resolution of a piston that has no solid surfaces, but a honeycomb, thanks to which it would have been possible to reach values of rigidity and resistance to high temperatures above to those of aluminum, also reducing the weight that was the serious starting handicap.
The Ferrari engine in the first races turned out to be quite thirsty in terms of consumption: even in Baku Vettel and Leclerc were forced to slow down to save fuel, while the W10 dominators would have completed the Azeri GP with over 7 kg of fuel in the tank.
With the new Shell oil in Maranello they are convinced to reduce the friction of moving parts, contributing to a slight increase in performance and a reduction in consumption. The word on the track ...
