ABSTRACT
 This paperdeals withhighlighting the
improvisationsin the working of an
recent trendsin Turbocharger.
TURBOCHARGER
 The basic working principleof
Turbochargeris"FORCED INDUCTION"
 The turbochargeris usedto increase
engine power.
 The Turbocharger isdrivenbyusing
exhaustgasfrominternal combustion
engine.
 The turbochargerhousingcontainsa
turbine andcentrifugal aircompressor
on the same shaft.
NEEDS OF A TURBOCHARGER
 Turbocharger are usedto increase
the volumetricefficiencyof the
engine byincreasingthe air-fuel
mixture enteringthe cylinder.
 Turbocharger are usedto decrease
the emissionof CO2.
TWIN TURBOCHARGER
 In twinturbochargerthere are two
turbochargerare usedforhigher
efficiency.
COMPOUND DOUBLE TURBINE
TURBOCHARGER
 In thisthere are two turbine are used
inturbochargerto attain higherrpm.
 COMPOUND DOUBLE COMPRESSOR
TURBOCHARGER
 In thisthere are two centrifugal air
compressorare usedin turbocharger
to attainhighpressure ratio.
GASOLINE TURBOCHARGER
 It providingmore low speedtorque,
transientresponse andpartial load
efficiency.
VARIABLE GEOMETRY
TURBOCHARGER
 The VGT withnowaste gate usesthe
exhaustenergytodrive the turbine,
whichin turn drivesthe compressor
to increase the volumetricefficiency
and increasingthe expansionratio,
poweroutput,OutputTorque.
 KEYWORDS: Forcedinduction, VGT,
Waste gate, CO2, ExpansionRatio,
volumetricefficiency.
