The Mercedes AMG is highly favourite team as season opening Australian Grand Prix. Even as many Formula 1 executives predict thart Mercedes can win this season title with new rules.
Our technical writer highlights there, Mercedes Energy Recovery System spec and its their unique weapon for 2014 F1.
The great advantage must be credited to the great work they have done technicians Brixworth, where the headquarters of Mercedes-AMG High Performance Power-trains, the seat in Northamptonshire where you understand the power – unit PU 106A Hybrid.
The Silver-Arrows has dedicated significant resources in the development of V6 Turbo engine from 1.6 liters of displacement. Looking carefully to the images that have been branched from the three-pointed star emerges a very interesting aspect: the technicians who deal with the installation of supercharger mounted the MGU-H between the turbine and the compressor, unlike Ferrari and Renault that would have settled inside the V.
The Mercedes in this way be able to enter in the air box of the V6 air cooler and, therefore, could draw more power , even if the electric motor would be subjected to greater tensional stresses . It will be interesting to see what will be the most effective solution.
Motor Generator Unit
MGU-K: The MGU-K is connected to the crankshaft of the internal combustion engine and is capable of recovering or providing power (limited to 120 kW or 160 bhp by the rules). Under braking, the MGU-K operates as a generator to slow the car (reducing the heat dissipated in the brakes) and so recovers some of the kinetic energy and converts it into electricity. Under acceleration, the MGU-K is powered (from the Energy Store and/or from the MGU-H) and acts as a motor to propel the car.
MGU-H: The MGU-H is connected to the turbocharger. Acting as a generator, it absorbs power from the turbine shaft to recover heat energy from the exhaust gases. The electrical energy can be either directed to the MGU-K or to the battery for storage for later use. The MGU-H is also used to control the speed of the turbocharger to match the air requirement of the engine (E.g. to slow it down in place of a wastegate or to accelerate it to compensate for turbo-lag.)
ERS: The Power Unit’s ERS (Energy Recovery System) uses the MGU-H and MGU-K plus Energy Store, plus some power and control electronics. Heat and Kinetic Energy recovered can be consumed immediately if required by the other MGU, or used to charge the Energy Store. The stored energy can be used to propel the car by the MGU-K or to accelerate the turbocharger by the MGU-H. Compared to 2013 KERS, the ERS of the 2014 Power Unit will have twice the power (120 kW vs 60 kW) and a performance effect 10 times greater.
