Magneti Marelli Motorsport
KERS (Kinetic Energy Recovery System) for F1: the electric motor produces torque during gear changes and at the same time allows for the reduction of fuel consumption.
Porsche LMP1 919 Hybrid engine
The motor-generator unit on the Porsche is driven by a separate turbine in the exhaust system.
Function test V4 race engine
HiSPD (High Specific Power Density) Technology
Less slot area and less volume.
Best thermal exchange => more
current density => less amount of
Little headers size.
Magneti Marelli MGU - MEDIUM RANGE MOTOR 60/120kW
Use motor-generator unit (MGU) in place of alternator
Power electronics control the MGU
2014 Ferrari power unit
Renault ENERGY F1-2014 power unit
Motor Generator Unit – Kinetic (MGUK)
The Kinetic Motor Generator Unit is the electrical machine mechanically linked to the drive train as part of the ERS.
Motor Generator Unit – Heat (MGUH)
The Heat Motor Generator Unit is the electrical machine linked to the exhaust turbine of a pressure charging system as part of the ERS.
With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
