The 1-liter, three-cylinder engine increases torque to 93Nm (from 90Nm in the K10B), and records carbon dioxide emissions of 84g/km when coupled with a 5-speed manual transmission.
Turbocharged & supercharged 4 cylinder, 1.6 litre
500Bhp @10000rpm, 360Nm @8500rpm
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.
