A compressor stall is a local disruption of the airflow in the compressor of a gas turbine or turbocharger. A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge. The severity of the phenomenon ranges from a momentary power drop barely registered by the engine instruments to a ...
Automakers use engine downsizing to help improve vehicles’ fuel efficiency and reduce emissions, and use turbocharger technology to recover power lost in the downsizing process. [5] The presence of LSPI limits automakers’ ability to capture the full potential of turbocharged engines to meet increasing fuel-efficiency requirements [ 1 ] and ...
Wet stacking is detectable by the presence of a black ooze around the exhaust manifold, piping and turbocharger, if fitted. It can be mistaken for lubricating oil in some cases, but it consists of the "heavy ends" of the diesel fuel which do not burn when combustion temperature is too low.
The anti-lag system (ALS) is a method of reducing turbo lag or effective compression used on turbocharged engines to minimize turbo lag on racing or performance cars. It works by retarding the ignition timing and adding extra fuel (and sometimes air) to balance an inherent loss in combustion efficiency with increased pressure at the charging side of the turbo.
Using a turbocharger spool valve to increase exhaust gas flow speed to the (twin-scroll) turbine; Using a butterfly valve to force exhaust gas through a smaller passage in the turbo inlet; Electric turbochargers [51] and hybrid turbochargers. A similar phenomenon that is often mistaken for turbo lag is the boost threshold. This is where the ...

Most turbocharged petrol engines use a single turbocharger; however, twin-turbo configurations are also often used. In motor racing, turbochargers were used in various forms of motorsport in the 1970s and 1980s. Since the mid-2010s, turbocharging has returned to several motor racing categories, such as Formula One and the World Rally Championship.
