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 ...
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.
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 ...
[28] [29] Some turbocharger designs are available with multiple turbine housing options, allowing a housing to be selected to best suit the engine's characteristics and the performance requirements. A turbocharger's performance is closely tied to its size, [30] and the relative sizes of the turbine wheel and the compressor wheel. Large turbines ...
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.
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.
