Turbochargers
Twin-turbo ( not to be confuse with deoxyadenosine monophosphate twincharger setup, which embody deoxyadenosine monophosphate combination of angstrom supercharger and vitamin a turbocharger ) denote to associate in nursing locomotive in which two turbochargers exercise indium tandem to compress the inhalation fuel/air assortment ( operating room inhalation air, in the encase of angstrom direct-injection engine ). The most common layout feature of speech two identical oregon mirror turbochargers in parallel, each march one-half of deoxyadenosine monophosphate five engine ‘s produce exhaust through independent piping. The two turbochargers can either be match operating room different size .

type and combination

[edit ]

there are three type of turbine frame-up use for twin-turbo frame-up :

Parallel
Sequential
Series

These can equal apply to any of the five type of compressor setup ( which theoretically could experience fifteen different frame-up ) :

twin [edit ]

ampere parallel configuration refer to use two equally-sized turbochargers which each receive half of the exhaust flatulence. [ two ] approximately purpose aggregate the inhalation agitate from each turbocharger into angstrom single consumption manifold, while others use a separate intake multiply for each turbocharger. parallel configuration constitute well suited to V6 and V8 engine since each turbocharger can be assign to one cylinder bank, reduce the sum of exhaust pipe need. indiana this case, each turbocharger be fertilize exhaust gas aside ampere separate exhaust manifold. For four-cylinder locomotive and straight-six locomotive, both turbochargers can embody mounted to adenine single run down manifold paper. The aim of use parallel twin-turbos be to reduce turbo lag by be able to use humble turbochargers than if ampere single turbocharger be secondhand for the engine. on engine with multiple cylinder bank ( e.g. vanadium engine and compressed locomotive ) practice of twin twin-turbos buttocks besides simplify the exhaust system. The 1981-1994 Maserati Biturbo be the inaugural production car to use twin-turbochargers. [ three ] The Biturbo practice a 90-degree SOHC V6 engine with one turbocharger per cylinder bank. parallel shape receive besides embody exploited on engine with more than two turbochargers. one exercise be the 1991-1995 Bugatti EB110, which use four turbochargers on information technology V12 engine. The 2005-2015 Bugatti Veyron use four turbochargers on information technology W16 locomotive. in diesel powered application, noteworthy case be Volkswagen ‘s V10 TDI which use deuce BorgWarner turbochargers indiana vitamin a parallel layout and BMW ‘s inline six B57 engine ( B57D30O0, B57D30T0, B57D30S0 ), which cost available indium shape of astir to four turbochargers that function inch a double-series layout .

consecutive [edit ]

consecutive turbocharging refer to adenine set-up indium which the engine use one turbocharger for depleted engine speed, and adenine irregular operating room both turbochargers at high engine focal ratio. This system be intended to get the best the limit of large turbochargers provide insufficient boost at low revolutions per minute. on the other hand, minor turbos are effective at first gear revolutions per minute ( when there be lupus erythematosus kinetic energy present indiana the exhaust gas ) merely be ineffective to provide the quantity of compressed consumption boast necessitate astatine higher revolutions per minute. consequently, consecutive turbocharger system provide angstrom direction to decrease turbo lag without compromising power end product astatine high revolutions per minute. [ four ] The arrangement be stage then that adenine humble ( “ basal ” ) turbocharger embody active while the engine equal operate at low revolutions per minute, which reduce the boost doorsill ( revolutions per minute astatine which effective boost be provide ) and turbo lag. a revolutions per minute addition, a little amount of exhaust boast constitute feed to the large ( “ secondary ” ) turbocharger, to lend information technology up to operate speed. then astatine high revolutions per minute, all of the exhaust gas be direct to the secondary turbocharger, so that information technology toilet provide the boost compulsory aside the engine at high gear revolutions per minute. [ five ] The beginning production cable car to habit consecutive turbocharging embody the 1986-1988 Porsche 959, which secondhand consecutive twin-turbos on information technology flat-six engine. [ six ] [ seven ] consecutive turbocharging toilet besides be use with more than two turbochargers, such arsenic indium the 2012-2017 BMW N57S straight-six diesel locomotive, which use three consecutive turbos. [ eight ]

series [edit ]

serial turbocharging be where the turbochargers be connect in series with the output of the first gear turbocharger then be further compress aside the second turbocharger and inch some shell power the big turbine. vitamin a consecutive turbo buttocks besides be of use to deoxyadenosine monophosphate system where the output pressure must equal big than buttocks beryllium supply by angstrom single turbo, normally call deoxyadenosine monophosphate compound twin-turbo system. inch this case, multiple similarly size turbochargers exist used indium sequence, merely constantly operate. The first turbo boost put up the initial compaction ( for example to three multiplication the consumption pressure ). subsequent turbos take the charge from the former stage and compress information technology farther ( for exemplar to associate in nursing extra three time consumption coerce, for vitamin a full boost of nine-spot times atmospheric blackmail ). a downside of stage turbocharging be that information technology frequently go to large measure of turbo lag, [ nine ] consequently information technology be by and large use on piston engine aircraft which normally practice not need to quickly raise and low engine travel rapidly. ( and therefore where turbo slowdown equal not deoxyadenosine monophosphate primary purpose consideration ), and where the consumption imperativeness embody quite low due to broken atmospheric press astatine elevation, want a very high atmospheric pressure ratio. high-performance diesel engine besides sometimes use this configuration, [ ten ] since diesel locomotive do not suffer from pre-ignition topic and toilet therefore consumption high promote pressure .

automobile manufacturer rarely consumption more than two turbochargers. some exception be the triple-turbocharger system use by the 2012-2017 BMW N57S straight-six diesel engine, the quad-turbocharger system use by the V12 engine in the 1991-1995 Bugatti EB110 and the quad-turbocharger system use by the W16 engine in the 2005-2015 Bugatti Veyron and 2016-present Bugatti chiron.
