MSYS 3-speed system
The Evoque_E program will investigate the benefits of high-speed motors and multi-speed transmissions for hybrid and electric vehicles. The project will build three development vehicles based on Land Rover’s new Range Rover Evoque, in mild hybrid, full hybrid and pure EV configurations.
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.
