2011 Hyundai Sonata 20T
Hyundai Sonata 2.0T
Hyundai Centrifugal America debuted its 2.0-liter Theta II turbocharged petrol direct-injection (GDI) locomotive in the 2011 Hyundai Sonata 2.0T at the 2010 New York Car Establish. With the add-on of the all-new 2.0-liter Theta II turbocharged GDI locomotive, the new 2011 Hyundai Sonata offers an unprecedented compounding of segment-leading fire efficiency and ability – with an estimated 34 mpg highway valuation, and 274 h.p.. Unmistakably, the Hyundai Sonata 2.0T produces these industry-leading prosody on even fire…bounty fire is not needed.
The new Hyundai Sonata is the offset Hyundai fomite to get both GDI engineering and a turbocharger. By the end of Hyundai’s 24/7 interpretation 2.0 merchandise enterprise (seven-spot new models in the adjacent 24 months), foursome nameplates bequeath be useable with GDI or the combining of GDI and a turbocharger. Turbocharging and GDI are office of “Hyundai Dark Ride,” the society’s environmental initiatory to proceed diligence leaders in fire efficiency and sustainability.
“The Hyundai Sonata 2.0T is a big exercise of what our Dark Effort ware scheme is doing for consumers,” aforementioned Trick Krafcik, Hyundai Centrifugal America prexy and CEO. “Entertain it – more h.p. than any of our V6 competitors, with improve mileage than any competitory 4-cylinder exemplar. We’re not fans of flexible at Hyundai, and the Sonata very demonstrates this prospect of our concern approaching.”
2011 Hyundai Sonata 2.0T
The 2.0-liter turbocharged GDI four-cylinder locomotive in the 2011 Sonata produces 274 hp at 6,000 rpm and 269 lb-ft of torsion from 1800-4500 rpm with veritable fire. The Hyundai Sonata 2.0T volition bear 22 mpg metropolis and 34 mpg highway (prelude estimates). Hyundai’s turbocharged locomotive features a twin-scroll turbocharger that when combined with the GDI organization results in instant superpower pitch. Twin-scroll turbochargers bear traditionally been victimised on more expensive highschool execution engines, but as with GDI, Hyundai has elect again to utilise this effective engineering in gamy bulk to its near democratic exemplar.
The 2.0T locomotive leave be useable on the SE and Modified trimness layer, with the 2.0T Modified acquiring extra upgrades, including:
TWIN-SCROLL TURBOCHARGER AND GDI TECHNOLOGY
Twin-scroll turbocharger designs sustain two eject gas inlets dual-lane by tear walls inwardly the turbine lodging, with both gas passages controlled by a waste-gate. A twin-scroll turbo recovers evening more vigor from the release than a single-scroll turbocharger thanks to a dual-lane multiplex. The twin-scroll conception separates the cylinders whose discharge gas pulses intervene with apiece former resulting in improved pressing dispersion in the expel ports and a more effective deliverance of expel gas vigour to the turbocharger’s turbine.
E.g., at the commencement of the ingestion diagonal of cylinder one, and when both the uptake and expel valves of cylinder one are unfold (valve lap menstruation), cylinder deuce-ace already starts its release shot with the eject valve out-of-doors. If the release passages of cylinder one and deuce-ace were attached, the expel gas throb from cylinder tercet would increment the rachis imperativeness of cylinder one. This would thin the trigger of the wise air and increment the total of hot residue gases privileged the cylinder. Withal, with the twin-scroll turbocharger frame-up, this hitch is minimized.
The termination of this master scavenging gist from a twin-scroll excogitation leads to meliorate press dispersion in the discharge ports and a more effective livery of tucker gas zip to the turbocharger’s turbine. This successively allows greater valve intersection, resulting in an improved timbre and amount of the air commission entry apiece cylinder. In fact, with more valve intersection, the scavenging burden of the tucker menses can literally haulage more air in on the inspiration english. Simultaneously, drafting out the finis of the low-pressure eject gases aid ingroup apiece cylinder with a denser and purer air tutelage. Utmost encourage from the turbocharger is 17.4 psi.
The twin-scroll turbocharger conception has various early advantages concluded traditional, single-scroll turbocharging systems, including:
Fundamentally, Hyundai Sonata’s twin-scroll turbo directs evening more air into the locomotive patch a compressor increases the force entrance the cylinder. This allows the air ingress the cylinder to be eve more obtusely jam-packed for higher compaction and amend execution, tributary to a more-efficient combust and fire efficiency.
Two key features of Hyundai’s twin-scroll turbocharger frame-up are:
Thanks to the unified stainless-steel turbine lodging with the release multiply, not lone is the burden and be of the cast dramatically decreased, the enduringness of the turbine trapping is likewise improved.
By adapting the motor-driven electric waste-gate, the rise insistence is incisively controlled. The binding imperativeness is decreased when turbo rise is not requisite by possibility the waste-gate, which improves fire efficiency. In plus, during frigidity starts, the waste-gate stiff spread which results in quicker accelerator light-off for decreased eject emissions.
A GDI fire livery arrangement contributes to improved fire efficiency and depress emissions. This shorter, more organize track of fire speech allows for greater restraint of the fire assortment at the optimal minute, thusly up efficiency. The fire is injected by a camshaft-driven, mellow insistency heart that operates at pressures capable 2175 psi. Organise injectant likewise utilizes a higher-than-normal 9.5:1 condensation proportion patch achieving a singular 137 horsepower-per-liter. The plunger heads are “dish-shaped” to gain burning efficiency in the cylinder.
WORLD-CLASS POWER-TO-WEIGHT RATIO, RIGIDITY AND SPACE
One of the platform targets for the 2011 Sonata technology squad was first power-to-weight proportion. This ism was besides applied to the Hyundai Sonata 2.0T, with the solvent of a best-in-class power-to-weight proportion of 12.2 hp per lb, importantly amend than any mid-size saloon challenger, and level meliorate than the performance-focused Chevrolet Camaro V6. Power-to-weight proportion pays dividends in both operation and fire saving, and is the key to Hyundai Sonata’s ranking functioning in both of these areas.
Additionally, all Sonatas are fat in ultra-high-strength brand, preeminent to foremost personify rigidness. The 2011 Sonata is 25 pct stiffer in crookedness and 19 percentage stiffer in deflection inflexibility than its harbinger, yet it is ignitor than nigh midsize sedans, besides oblation more home way.
SIX-SPEED AUTOMATIC TRANSMISSION
Hyundai’s allegiance to fashioning the Hyundai Sonata 2.0T super fire effective continues with a six-speed robotic transmittance with SHIFTRONIC manual controller.
Hyundai’s all-new six-speed robotic A6LF2 transaxle is another way the society is merging its goals of up fire efficiency and reduction emissions. Shifts are slick polish with an choice of manual ascendance done the SHIFTRONIC sport.
Drivers can entree the SHIFTRONIC boast by moving the appurtenance chooser into a furcate gat. Push the chooser advancing or pull it rear leave slip the contagion up or pile consecutive, adding to driver ascendance. Turbocharged Sonatas testament besides sport guidance wheel-mounted larrup shifters. A crystallize LCD read-out on the board shows the appurtenance existence ill-used.
Intentional for transversal locomotive applications in rider cars and SUVs, the new press transmitting puts Hyundai into an elect grade of automobile manufacturers who let intentional their own proprietorship six-speed automatonlike transmissions. The enduringness of the invention is its unparalleled layout which makes it littler, more concordat and light than any over-the-counter six-speed contagion on the marketplace nowadays.
For the client, the new six-speed delivers a functioning boundary. The gearbox has no dipstick because it is filled with robotic transmitting unstable that is full for the living of the fomite nether formula employment weather, thereby reduction sustainment costs.
Highly-developed ended a four-year flow, this new six-speed machinelike is 26.4 pounds hoy than the five-speed it replaces. It is likewise 1.6 inches shorter and well simpler, having 62 fewer parts, which is key to increased lastingness, barge slant and depress be.
When it comes to transmissions, more gears are emphatically ameliorate. The summation of a 6th cogwheel enables nigher spacing betwixt geartrain ratios providing a improve counterbalance of execution and fire thriftiness piece the across-the-board boilersuit gearing proportion helps birth substantial speedup.
The gearbox has iii planetal gearsets and a unparalleled flatbed torsion convertor that shortens the whole’s boilersuit duration by 0.47 inches. Quatern quill differentials meliorate enduringness and advance understate sizing.
Another representative of technology inventiveness is ground in the designing of the hydraulic force controller whole. Flimsy manufacture deviations from one solenoid valve to the following oftentimes movement variation in the hydraulic imperativeness and impress switching preciseness and timbre. The transmittance featured in the Sonata smartly integrates accommodation screws in the valves that enable apiece of the ogdoad valves to be graduated at the manufactory. This sport ensures unchanging hydraulic press at any shifting detail which facilitates a heights arcdegree of preciseness and command requisite to bear fasting, quiet and exact shifts end-to-end the rpm grasp.
