The electric compressor’s power is provide by the 48-V on-board system.
Enabling actuation of the electric compressor is linked to safety and energy-efficiency related conditions. Fault-free electric compressor hardware, including the 48-V vehicle electrical system, is essential for the electric compressor to be enabled.
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.
