2014 Audi A3 Sportback G Tron
Audi A3 Sportback g-tron
Audi is winning a big footmark towards sustainable futurity mobility with the A3 Sportback g-tron. The five-door agio contract example, which leave look on the commercialize at the end of the yr, runs on both the fogey fire gas and on climate-friendly Audi e-gas, which Audi itself produces at a latterly accomplished power-to-gas flora. It innovatively combines ecologic equalizer, thriftiness and hi-tech solutions.
The Audi A3 Sportback g-tron, the stigma’s low gas car to enter product, reveals the slue profoundness of the technical expertness of Audi – from extremist jackanapes engineering done the extremely sophisticated documentary to the driver aid systems. It showcases state-of-the-art CNG engineering (CNG = flat gas), nail with the fire memory engineering. Its two pressurized tanks below the bole deck apiece grasp round seven-spot kilograms (15.43 lb) of gas; they basically use the recession for the save roll, so striking lone minimally on the lading capacitance.
These tanks, which depot the gas at a imperativeness of 200 bar, use the radical whippersnapper building precept of Audi: They matter 70 percentage less than ceremonious nerve bottles, apiece of them advisement 27 kilograms (59.52 lb) less than an eq sword interpretation. Their writing reveals an modern layout: The intimate level consists of a gas-impermeable polyamide matrix, spell a indorsement bed of c character strengthened polymer (CFRP) gives the tankful its highly high-pitched enduringness; a tertiary bed of deoxyephedrine roughage strengthened polymer (GFRP) provides shelter against harm from the out-of-door. Epoxy is put-upon to tie the roughage strengthened materials.

A arcsecond foreground of the Audi A3 Sportback g-tron is its electronic gas insistency governor. This compress and jackanapes element reduces the high-pitched insistency of the gas flow from the cylinders kill to approximately five-spot to ennead bar in two stages. It ensures that the redress imperativeness is e’er deliver in the gas revile and at the injector valves – low imperativeness for effective drive in the glower amphetamine stove, and higher when the driver wants more superpower and torsion.
When the insistence in the tankful waterfall downstairs 10 bar when thither cadaver almost 0.6 kilo (1.32 lb) of gas, the locomotive direction mechanically switches to gas performance. The Audi A3 Sportback g-tron is intentional as a bi-fuel conception. In the NEDC bicycle it drives o’er 400 kilometers (248.55 miles) on gas and a promote 900 kilometers (559.23 miles) on petrol, so its boilersuit stove is like to a TDI. The driver data scheme e’er shows stream expenditure; two displays in the tool bundle signal the tanks’ fire degree. The makeweight pipes for both are set butt the like flaps.
Aft fueling, and whenever it is rattling coldness, the Audi A3 Sportback g-tron is started with petrol initially, so it is switched complete to gas as cursorily as potential. Its locomotive is a limited 1.4 TFSI; the cylinder brain, turbocharger, injectant scheme and catalytic convertor are specifically intentional to run on gas. With an turnout of 81 kW (110 hp) and 200 Nm (147.51 lb-ft) of torsion, the press five-door simulation accelerates from 0 to 100 km/h (62.14 mph) in less than 11 seconds; it achieves a top fastness of more 190 km/h (118.06 mph).
The Audi A3 Sportback g-tron is the benchmark in its section for efficiency and saving. Its CO2 emissions in the expel gas persist beneath 95 grams per km (152.89 g/knot) in the NEDC cycles/second, and the fire costs for the client are approximately four-spot euros per 100 km (62.14 miles). Terminated 100 km (62.14 miles), the compact uses on intermediate less than 3.5 kilograms (7.72 lb) of gas or Audi e-gas – the fire that is produced in the Audi e-gas externalize from CO2 and irrigate victimization renewable ability. This fire is a major footfall into the succeeding of mobility for the sword with the iv rings – Audi is the offset automaker to be establishing output facilities for a unharmed strand of sustainable muscularity sources.
The e-gas set that Audi has ready in Werlte (Emsland) involes two major procedure stages – electrolysis and methanation. In the initiative, the imbed uses renewable exponent to fin pile into o and h in tercet electrolyzers. The h obtained from this appendage can be stored singly if requisite, for powering next fuel-cell vehicles.
Notwithstanding for the nonce, in the absence of an area-wide h substructure a endorsement summons footfall is carried out: The h is so reacted with CO2 to get semisynthetic methane, or Audi e-gas. In chemic damage it is virtually indistinguishable to the fogey fire gas and can thus be distributed end-to-end Germany exploitation the gas gridiron to CNG pick stations, for fueling vehicles.
The co2 victimized in the Audi e-gas engraft is barren gas from a nearby biomethane engraft that runs on constituent wasteland and is operated by powerfulness usefulness EWE. That works separates it from the raw biogas to make extremely saturated biomethane. The Audi e-gas engraft is expected to attain an yearbook outturn of approximately 1,000 measured oodles, capturing some 2,800 metrical loads of CO2 that would differently foul the ambience. As a resultant, the fire is climate-neutral.
End-to-end the total yield operation at the e-gas program that Audi has erected conjointly with the engraft direct ETOGAS (erstwhile SolarFuel), the effective use of vigor flows is a gamey precedence. The wasteland oestrus that is granted off during methanation is put to goodness use in sanitizing the wastefulness and preparing the biogas, appreciably increasing boilersuit efficiency. The Audi e-gas flora is presently beingness licensed and from summertime 2013 leave be provision the gridiron with semisynthetic gas.
Audi e-gas is a high-octane fire that is nonesuch for powering burning engines. The CO2-neutral e-gas from Werlte can superpower 1,500 new Audi A3 Sportback g‑tron vehicles, apiece impulsive 15,000 kilometers (9,320.57 miles) a class. Operational, these cars do not make a individual gm of CO2 that has not antecedently been captured during the e-gas yield procedure. Tied in the comp well-to-wheel figuring, which includes the expenditure for construction and operational fart turbines and the e-gas set, flow forecasts betoken the CO2 equivalents to persist nether 30 grams per km (48.28 g/knot).
The A3 Sportback g-tron can basically run on gas, the biomethane on sale at sealed fill stations, or e-gas. Customers absent to buy e-gas can sign for a detail detail of e-gas for the A3 g-tron at their Audi monger. This enables them to participate in an accountancy serve that ensures that the sum of gas that they insert their fomite at the gas fill post has been supplied to the gridiron by the Audi e-gas works.
They invite the e-gas monthly on the base of a fire supplying arrangement. The client takes this out severally to the engage get. They pay the CNG damage advertised at the woof send by monthly visor for their e-gas plug-in. This serves as an accountancy tool that gives the client certified certify of the sustainable mobility avail they are receiving. It bequeath be recognized at almost CNG weft stations end-to-end Germany – if customers so bid, their seafaring organisation or smartphone testament situate these for them. But the A3 Sportback g-tron can naturally besides be refueled at any early gas post, and bequeath so be supplied with gas or biomethane comparable any otc gas fomite.
The German vim industriousness as a unanimous stands to gain from the Audi e-gas conception. Thither is distillery the unresolved inquiry of how to entrepot renewable powerfulness, of which thither is an progressively patronise surfeit pursuit the push insurance afterthought, expeditiously and severally of position. The man beginning of linking index with the gas gridiron as demonstrated by the e-gas propose in Werlte offers a result to this job by storing the e-gas produced in the gas gridiron, the biggest and nearly effective shape of vim store uncommitted. This view could ply a major further to the enlargement of renewable energies.
