F1 » Renault F1 has ‘huge job list’ for 2015


Goldie, Both FERRARI and Mercedes use a split turbosuperchager with the MGU-H in-between the compressor and turbine while Renault use a combined compressor and turbine turbosupercharger with the MGU-H in front of the compressor. The FERRAI PU is the smallest and most compact of the three on the grid. I recommend you visit “mat somersf1 powerunit architecture “ where you can understand much better than my explanations.

F1 » Renault F1 has ‘huge job list’ for 2015


The two (2) drive systems used in the 2014 PU turbocharger (exhaust gasses and electric) makes it a turbosupercharger. This system uses a common shaft for the compressor, Turbine and MGU-H, no part of the three (3) can be de-clutched. Rotational speed (rpm) for the three (3) components is the same at all time (max 100k rpm). Re the fuel used in F1, With the high revving (18k rpm engines) a totally different fuel than that used on road cars was used, having a (burn time) 3 times faster than what is used on the road car, still both slow and fast burn fuel (for that level of rpm) was used, the difference being in the weight/power output of the fuel, which in turn means the total weight of the car on track, high power tracks/ low power tracks needs. The 2014 fuel needs is more critical, not because of the burn time (a slower burn time is needed at the rpm’s in use) but because of the weight versus volume and power.

F1 » Renault F1 has ‘huge job list’ for 2015


Growing old I suppose, in old gits circles like me what differentiates a “supercharger” (air compressor) from a “turbocharger” (air compressor) is the means of drive. When both means of drive (which differentiate what type the compressor is) are used the compressor is called a “turbosupercharger”. A supercharger (air pump/compressor) some of the types are Laysham-twin screw, sliding vane, and scroll-G-Leder are mechanically driven by gear, shaft, belt, chain or electric. A supercharger offers better engine response than a turbocharger, but can absorb up to 1/3rd the power produced by the engine. A turbocharger is driven by the exhaust gasses which are for free re the power produced by the engine. I have came upon systems of compounded superchargers, (one boosting the other), as well as compounded turbochargers, also of compounded turbocharger pumping into (boosting) a supercharger. To be continued.

F1 » McLaren fails to reach driver decision


More to the point, My sources have revealed/speaks off “It is Alonso and Dennis who have been the “sticking point” and that there may be yet a rather big surprise in store” “the power struggle might well be between a driver and a team boss” “it is uncertain whether both will be part of the team in 2015, unless huge helpings of humble pie are shared”.

F1 » McLaren fails to reach driver decision


The indecision over their driver line-up for 2015 is an indication of an intense political struggle, but now some sources are suggesting that there might even be a bigger surprise in store, as they are suggesting that the sticking point might well be a mess between what Honda wants and what Dennis wants with Alonso in between, these sources says that it is uncertain whether both Dennis and Alonso will be both part of the same team/or wants to be part of the same team.
