Volvo launches an energy-efficient 2-litre GTDi engine with unique turbo system

Volvo Car Corporation is introducing an all-new four-cylinder 2-litre GTDi (Gasoline Turbocharged Direct Injection) engine in the Volvo S80, V70 and XC60, offering great performance and efficiency all in one.

New Volvo-developed turbocharging technology, direct injection and twin variable camshafts give a unique combination of low fuel consumption, low emissions and high performance across a wide rev range - all in a particularly compact format.

The new petrol engine, the 2.0 GTDi, produces no less than 203 hp despite its compact size and cylinder capacity. It pumps out 300 Nm of torque already from 1750 rpm thus securing a refined driving experience.

"We've succeeded in making a four-cylinder engine that is as powerful as a 2.5-litre five-cylinder unit, and it's also much more energy-efficient. This is a very welcome both for those customers who want high performance as well as supreme driveability and for the environment that benefits from the improved fuel efficiency. One of the most important reasons behind the results is our new, patented turbo system that has been tailor-made for smaller energy-efficient engines," says Magnus Jonsson, head of Product Development at Volvo Cars.

Less is more - Meet the next generation turbo technology

The turbocharger system has been developed in cooperation between Volvo Cars, Borg-Warner Turbo System and steel component manufacturer Benteler Automotive. The turbocharger (K03) is the market's smallest in relation to the engine's maximum output. The turbo not only gives excellent performance properties, it also improves exhaust aftertreatment by enabling quick heating of the catalyst.

The turbine housing is integrated into the manifold, an efficient solution with which Volvo already had previous good experience. The difference is that the new manifold and turbine housing are made of sheet steel instead of a casting. The sheet is lighter and more compact and, above all, this system generates less heat owing to its extra insulating layer. This allows high gas flow temperature and thus more efficient combustion.

A manifold made of sheet steel is admittedly nothing new but so far it has only been used in combination with cast turbine housing. The new, fully integrated turbo package made entirely of sheet steel is a world innovation and has been patented by Volvo.

This innovative technology has made it possible to shape the exhaust ducts optimally to allow an optimal gas flow and generate the maximum pulse effect for the highest possible turbine efficiency. The pulse dynamics can thus be utilised to the limits in order to generate a high power output level across a wider range of engine revs. This translates into close to immediate response and good acceleration at both low and high speeds.

"High performance is important to many customers. However, being an innovative and highly efficient powertrain, there is also a significant gain in both fuel consumption and emissions with this technology" says Magnus Jonsson. "A Volvo S80 with this engine and automatic transmission consumes just 8.3 litres of fuel per 100 kilometres."

Efficient direct injection starts the turbo quickly

The new engine features direct injection. The injectors have seven holes for precisely controlled injection into each cylinder. The injectors are side-mounted.

Direct injection gives a high fill rate in the combustion chamber, efficient combustion and low emissions. Thanks to this high fill rate, the turbo also starts spinning earlier, delivering alert response from low revs. This in turn results in swift acceleration and good driveability even from low speeds.

Direct injection also contributes to quick and stable combustion at high loads, and thus smooth engine operation even when the accelerator is floored.

The injection system is supplied by Bosch.

Twin VVT (Variable Valve Timing)

Volvo's new GTDi engine utilises variable timing for both camshafts. Both the inlet and the exhaust valves' opening times can be varied to optimise the overlap and ensure the correct fill rate in the combustion chamber irrespective of engine revs. This gives the combustion process maximum efficiency throughout the rev range and helps generate rapid acceleration at all speeds.

Both VVTs are of the conventional vane-type. The rotation of the inner and outer rotor is regulated by hydraulic pressure from the engine oil.  By opening and closing the oil control valves, the oil pressure and flow through the VVTs are changed until the desired angular deviation between the inner and outer rotor is achieved. The oil control valves are controlled by software in the Engine Management System using feedback from the cam position sensors.

"By combining direct injection and VVT with our new patented turbo system, we can offer an engine with low fuel consumption and low emissions, without having to compromise on performance or driving properties," says Magnus Jonsson. "We have created an engine that is as efficient in the city as it is on the highway. And since the design is based on an already-existing engine concept, we can offer more car buyers a highly fuel-efficient alternative at a reasonable price."

In combination with Powershift or manual gearbox

The engine will be offered in combination with Volvo's automatic six-speed Powershift transmission or a six-speed manual gearbox.

This new six-speed double-clutch automatic transmission combines the efficiency and driving dynamics of a manual transmission with the ease of a quality automatic transmission. The clutch activations are co-ordinated so that no torque interruption occurs during gear changing. This provides both the ease and permanent motion of a conventional automatic transmission and the performance of a manual transmission.

A key global powertrain for Volvo

Volvo's new 2.0 GTDi engine is being initially launched on markets that offer tax incentives for engines below two litres in displacement: South-East Asia, the Netherlands, China and Japan.

Din cate vad eu e o evolutie a motorului T4.

[ateo 3]

Fiind posesor de S60 2.0T sper ca acest nou 2.0GTDI sa fie disponibil si pe noul S60. Ar fi chiar, in ochii mei, masina ideala sa imi inlocuiasca masina actuala . In alta ordine de idei, daca ajungem la cineji, renunt la idee.

Ar fi fost frumos sa ramana 5 cilindrii, nu 4. Da, intr-adevar, e o evolutie a T4 mai degraba decat a motorului de 5 cilindrii. Daca asta este cazul, ar fi bine, consumul sa fie al dracu de mic pt ca puterea nu a crescut (3CP).

Eu, in locul lor, as aplica aceasta noua tehnologie la toate motoarele din gama, astfel, poate s-ar reduce costurile de productie si dezvoltare motoare noi, si motoarele ar deveni mai competitive. Cu toate ca nu ma plang, sunt chiar foarte multumit de motorul masinii mele si am mai condus alte motorizari de la Volvo si la fel, nu ma plang, majoritatea motoarelor sunt cu una-doua generatii in urma. Recunosc ca pt vremea lor, erau excelente (vezi 2.0T de la Volvo cand a aparut era cu vreo 30-40 CP mai performant cu ce avea de oferit Audi, BMWetc.). Dar, timpurile au trecut...

[Brava 554]

Motorul este Volvo sau Pejo ? 

[andy.ro 32]

fix nu ma intereseaza poa sa fie si ARO daca e facut la indicatiile si standardul Volvo.

[ateo 3]

@andy.ro

S60 2.0GTDI 245CP?!?

Transmisie?

Echipare?

Stii ceva ce nu stim noi? (Banuiesc ca da)

Care 2 share?

[andy.ro 32]

intrebarea care se pune este alta ... cat de rapid iti doresti noul S60? )

[ateo 3]

S60 R, baby, daca e vorba asa   

[iulirx 614]

ia-l acu cit e facut de europeni !!

nu cred ca va mai apare R-ul...

un s60 benzinar cu 300 nm nu e rau deloc. ii mai dai 100 nm si esti stapin !

(una bucata bere andy, nu ?)

Exact

[mironb 61]

La cate tampenii de management baga astia, probabil ca si turbina e inseriata cu motorul si o sa trebuiasca sa mergi la reprezentanta sa o programezi

Stai linistit, ca la volvo oricum nu prea exista upgrade-uri de turbine bolt-on si tre sa iti faci galerie de evacuare custom ! Vei face acelasi lucru si aici, dar mai scump. Sau faci o turbina hibrid din cea existenta si nu mai schimbi nici o galerie. Solutii exista

[alexpopeystar68 313]

Lamuriti-ma si pe mine, nestiutorul : are si compresor si turbina, dupa cum se vede in poza? adica ceva cam  cum e TSI-ul de la vw, al care a luat premiul pt cel mai bun motor nou in 2007, parca; la turatii mici, pana in 2000 lucra compres, intre 2000 si 2500 ambele si peste numai turbina - o chestie super !  asa o fi si la S60 ?

[mironb 61]

Compresorul e antrenat de obicei printr-o curea si e cam prin zona alternatorului. Nu cred ca motorul asta are si turbina si compresor.

[iulirx 614]

n-are compresor.
