Sporty Dynamism, Superb Comfort: The Audi 1.8 TFSI Source: Audi AG TFSI technology underwent its baptism of fire in the victories at Le Mans, the toughest endurance race in the world. The superiority of this combination of petrol direct injection and turbocharging has now been demonstrated on ordinary roads in the 2.0 TFSI, which has been available since September 2004. Audi is now stepping up its campaign with the successful TFSI concept: the new high-tech 1.8 TFSI engine combines sporty dynamism with outstanding smoothness, and blends a spontaneous power characteristic with ample refinement. The new engine generation bears the project number EA888 and follows in the footsteps of the already legendary 827 series, one of the most successful families of engines in automotive history. This compact, high-performance, economical four-cylinder version made its debut back in 1972 in the Audi 80. In the intervening years it has been fitted over 40 million times as the power unit for countless Audi models and various other vehicles of Volkswagen group brands. It has been steadily refined over the years, always remaining at the cutting edge of technology. Pioneering achievement by Audi The latest evolutionary stage of this engine range is the much-acclaimed 2.0 TFSI. At Audi, it is being used in the A3, A4 and A6, in three different performance versions ranging from 170 to 220 bhp. The 2.0 TFSI has most latterly demonstrated its special potential in the new Audi S3, with an output of 265 bhp and peak torque of 350 Nm. This engine is yet another pioneering achievement, because Audi has once again become the first manufacturer in the world to combine petrol direct injection with turbocharging in volume production. The result is an engine that is not only very popular with customers for its power characteristic and propulsion, but has also garnered the approval of the experts: a jury of 56 leading journalists from 26 different countries awarded the 2.0 TFSI the title of "Engine of the Year" for two years in succession (2005 and 2006). This was therefore an ideal basis for developing the next logical stage. Audi's engineers had drawn up a long list of tasks for the new project. Right at the top – as is always the case at Audi – was maximum driving fun, as the result of high responsiveness, performance and torque even at low engine speeds. The engine was simultaneously to be quiet, smooth and low on vibrations, suitably reflecting the standards of comfort expected of a sporty premium car. The essential requirements of course included reduced fuel consumption, as well as the potential to keep meeting the toughest emission limits in the world, on a wide range of fuel grades. Finally, the new family of engines is to serve as a genuinely universal engine for use on all five continents. Ultra-fine fuel jets, precisely distributed Audi regards FSI technology with turbocharging, now systematically refined for the new engine, as the best way to achieve all these objectives. With FSI technology, fuel is injected directly into the combustion chamber. The new 1.8 TFSI does this at a maximum pressure that has been increased to 150 bar. Together with the new six-hole injectors and air movement in the combustion chamber controlled by charge movement flaps, it guarantees highly homogeneous mixture preparation and very efficient combustion. This supports the engine's agile characteristics and spontaneous power output, as well as its very low fuel consumption in practice. A new type of high-pressure pump supplies this injection pressure. The pump is driven by a four-fold cam on the exhaust camshaft. This reduces the operating forces required and boosts precision, thus improving the emissions. The high-pressure lines through which the fuel reaches the injectors at maximum pressure are made entirely from stainless steel. The new six-hole nozzles distribute the ultra-fine fuel jets with precision inside the combustion chamber. Dual injection – the distribution of the fuel quantity between the admission stroke and the compression stroke – brings further advantages for the homogenisation of the mixture and heating of the catalytic converters after a cold start. Turbocharger with improved aerodynamics The watercooled turbocharger K03, from Borg Warner, maintains optimum cylinder filling. An optimised turbine wheel improves the aerodynamics inside the charger, as a result of which responsiveness lower down the engine range is further enhanced. In the intake system, the redesigned charge movement flap reduces flow losses and simultaneously assures a very homogeneous distribution of the mixture. The result is an exceptionally spontaneous engine response to the accelerator at all engine speeds: at just 1,000 rpm, the new 1.8 TFSI develops a torque of 165 Nm, with maximum torque available very early on and across the extremely broad range of 1,500 to 4,200 rpm. The peak output of 160 bhp is likewise maintained across an extremely broad plateau of 5,000 to 6,200 rpm. This permits economical gearing that is nevertheless of a sporty character. With a compression ratio of 9.6:1, the engine is designed to run on premium-grade fuel (95 RON). In the A3 with manual gearbox, the combined-cycle fuel consumption is consequently a modest 7.3 l per 100 km. Excellent refinement The TFSI concept is underpinned by the entirely new basic engine. In essence, the only thing its engine block has in common with its precursors is the cylinder spacing of 88 millimetres. Audi's engineers chose this dimension because it keeps the dimensions very compact and allows the engine to be installed either longitudinally or transversely in the engine compartment. Two counter-rotating balancing shafts are integrated into the crankcase. They are driven by the crankshaft via a toothed chain, and completely suppress the free inertial forces of the second degree that are inherent to this design. Low-frequency humming and vibration are consequently eliminated very effectively. The development engineers were especially eager to achieve very good acoustic behaviour and smoothness. After all, the new TFSI power units were meant to be exceptionally refined, not just very powerful. Grey cast iron was chosen as the material for the engine block in view of its better acoustic properties. With a finished weight of 33 kilograms, the engine block nevertheless genuinely merits being described as a lightweight design. The extra-rigid basic structure of the block, acoustically optimised add-on parts and acoustically isolated covers reflect how much fine-tuning went on at the design computers and test benches. The crankshaft is instrumental in determining how smoothly an engine runs: what matters are not just the eight counterweights; its optimised rigidity, underpinned by large main bearings with a diameter of 58 millimetres, is really the determining factor. The result is that even at full load, the 1.8 TFSI is a smooth-running, acoustically restrained, spontaneous engine. High tech in every detail As Audi's first four-cylinder engine, the 1.8 TFSI is equipped with a toothed chain to drive the valve gear. The compact chain does not need changing. There are, to be more precise, three chains: the long one to drive the camshafts, and two short ones for the oil-pump and balancing-shaft drives. The use of special toothed chains known as "silent chains" adds further to the outstandingly restrained sound of the new engine. The continuous adjusting mechanism of the intake camshaft has been reengineered; this vane-type system now responds much more swiftly than previous concepts. It promotes a spontaneous response from the engine even starting at low engine speeds. The engineers also paid attention to keeping the design compact. This led to innovative solutions such as the highly ingenious auxiliaries rack. As well as performing its traditional function, it incorporates the oil cooler, oil filter and oil pressure switch. The formerly basic rack has consequently become the veritable turntable of the oil and water circuits. The integration of the water pump, thermostat and temperature sensor into a single housing also saves space. The turbocharger forms an integral module together with the exhaust manifold. This allows the positioning of the ceramic primary catalytic converter particularly close to the engine, promoting rapid heating-up and, in conjunction with the ceramic close-coupled catalytic converter, keeping emissions low. Career plan as a universal engine With these genes, the new 1.8 TFSI has the potential to keep on satisfying the toughest emission limits in the world. After all, it is destined for a career as a true "universal engine". The highly promising new engine that offers ample scope for further development will be going into production simultaneously at Audi's engines plant in Gyцr, Hungary, and in Dalian, China, in autumn 2006, when it will become the first petrol direct-injection engine on the Chinese market. The TFSI concept is likewise ideally equipped for use in the USA and South America, where fuel grades to some extent vary considerably. |
Four cylinder EA888 petrols This latest EA888 family of internal combustion engines is anticipated to be an eventual complete replacement of the EA113 range. It was wholly designed and developed by AUDI AG. The only common feature with its predecessors is the sharing of the same 88 millimetres (3.46 in) cylinder spacing - which keeps the engine length relatively short, meaning it can be installed either transversely or longitudinally. Grey cast iron (GJL 250) remains the choice material for the cylinder block and crankcase, due to its inherent good acoustic dampening properties. This all-new EA888 range is notable for utilising simplex roller chains to drive the two overhead camshafts, instead of the former engines' toothed-rubber timing belt. Like the final developments of the former EA113 engine generation, all EA888s only use the Audi-created Fuel Stratified Injection (FSI) direct injection. Furthermore, EA888 engines are also able to utilise the Audi-developed 'valvelift' technology, which complements the existing variable valve timing. This new family of engines is scheduled to be universally available for all markets on five continents, within all marques of the Volkswagen Group. The former EA113 range still remains in production. 1.8 R4 16v TSI/TFSI 88-125kW (EA888) identificationparts code prefix: 06H, 06J; ID codes: BYJ engine displacement & engine configuration 1,798 cubic centimetres (109.7 cu in) EA888 inline-four engine (R4/I4); bore x stroke: 82.5 by 84.1 millimetres (3.25 in × 3.31 in), stroke ratio: 0.98:1 - 'square engine', 449.6 cc per cylinder; compression ratio: 9.6:1, 88 millimetres (3.46 in) cylinder spacing cylinder block & crankcase GJL 250 grey cast iron; 33 kg (73 lb), die-forged steel crankshaft with five 58 mm (2.28 in) diameter main bearings, two toothed chain-driven counter-rotating balance shafts suppressing second degree free inertial forces and oil pump, horizontal-baffled oil sump cylinder head & valvetrain cast aluminium alloy; four valves per cylinder, 16 valves total, low-friction roller finger cam followers with automatic hydraulic valve clearance compensation, toothed chain-driven double overhead camshaft (DOHC), continuous vane-adjustable variable intake valve timing aspiration hot-film air mass meter, cast alloy throttle body with electronically controlled Bosch E-Gas 'drive by wire' throttle butterfly valve, plastic variable length controlled intake manifold with charge movement flaps controlling combustion chamber air movement, BorgWarner K03 water-cooled turbocharger incorporated into cast iron exhaust manifold, sandwiched central front-mounted intercooler (FMIC) fuel system fully demand-controlled and returnless; - fuel tank–mounted low-pressure fuel pump; Fuel Stratified Injection (FSI): single-piston high-pressure injection pump driven by a four-lobe cam on the exhaust camshaft supplying up to 150 bars (2,180 psi) fuel pressure in the stainless steel common rail fuel rail, four combustion chamber sited direct injection sequential solenoid-controlled six-hole fuel injectors, air-guided combustion process, multi-pulse dual-stage injection during the induction and compression stroke with homogeneous mixing, stratified lean-burn operation with excess air at part load, 95 RON unleaded ultra-low sulphur petrol ignition system & engine management centrally positioned longlife spark plugs, mapped direct ignition with four individual direct-acting single spark coils; Bosch Motronic MED electronic engine control unit (ECU), cylinder-selective knock control via two knock sensors, permanent lambda control exhaust system cast iron exhaust manifold (with integrated turbocharger), close-coupled and main catalytic converters - both ceramic DIN-rated motive power & torque outputs, ID codes 88 kilowatts (120 PS; 118 bhp) @ 4,000-6,200 rpm; 230 newton metres (170 lbf·ft) @ 1,500-3,650rpm — Audi A4 (B8), SEAT Exeo 118 kilowatts (160 PS; 158 bhp) @ 4,500-6,200 rpm; 250 newton metres (180 lbf·ft) @ 1,500-4,500 rpm, 165 N·m (122 lbf·ft) from 1,000 rpm — CDAA Škoda Yeti 112 kilowatts (152 PS; 150 bhp) @ 4,300-6,200 rpm; 250 newton metres (180 lbf·ft) @ 1,500-4,200 rpm, 165 N·m (122 lbf·ft) from 1,000 rpm — CDAB Škoda Yeti 118 kilowatts (160 PS; 158 bhp) @ 4,500-6,200 rpm; 250 newton metres (180 lbf·ft) @ 1,500-4,500 rpm — Audi A4 (B8), Audi A3 Mk2 (8P), Audi TT Mk2 (8J), SEAT Exeo 125 kilowatts (170 PS; 168 bhp) @ 4,800-6,200 rpm; 250 newton metres (180 lbf·ft) @ 1,500-4,800 rpm — Audi A5125 kilowatts (170 PS; 168 bhp) @ 3,800-6,200 rpm; 320 newton metres (240 lbf·ft) @ 1,400-3,700 rpm — Audi A4 (B8) (2012-), Audi A5 applications Audi TT Mk2 (8J), Audi 8P A3, Audi B7 A4, Audi A4 (B8), Audi A5, SEAT Leon Mk2 (1P), SEAT Altea XL, Škoda Yeti, Škoda Octavia Mk2 (1Z, Ming Rui), Škoda Superb Mk2 (3T), VW Jetta Mk5/Sagitar, VW Passat B6, VW Passat CC references of the German technical engine publication mtz, press release 11/2006: "Der neue Audi 1.8 TFSI-Motor" "Sporty Dynamism, Superb Comfort: The Audi 1.8 TFSI".

To Sh. Sudhir Rao (Managing Director) SKODA Auto India Private Limited A-1 / 1, M.I.D.C., Five Star Industrial Area, Shendra, Aurangabad - 431 201 Tel: +91 240 6631 111 / 222 / 333, Fax: +91 240 6631299, 6631199 24 hour helpline: 1800 209 4646 & 1800 102 6464 Dated: 14-09-2012 (I would request the Customer Care personnel to kindly forward this email to Shri Rao personally, as it is of important concern) Dear Mr. Rao, I was and am a die hard Toyota fan for the sheer bullet proof reliability and go anywhere attitude of their vehicles. They lacked in many luxury feature but out lasted all my other vehicles due to their fantastic built coupled by excellent after-sales-service. I have owned a Corolla (my long term ownership thread is here - http://www.team-bhp.com/forum/long-t...55-000-km.html (Toyota Corolla 2004 - Long Term Ownership Report 55,000 KM) ) and recently I also bought a Fortuner (ownership thread is here - http://www.team-bhp.com/forum/test-d...uilt-last.html (The Millennium Falcon - Toyota Fortuner - The Raptor that is built to last) ). That aside I was looking for something more as I moved up in life and wanted to taste some more luxury. So even after hearing many Skoda after-sales horror stories, I decided to put my money on a Skoda Superb Petrol MT a few months back. My ongoing detailed ownership thread of the said vehicle is here - http://www.team-bhp.com/forum/test-d...t-destiny.html (Skoda Superb - A tryst with destiny) . Now as will be clear with the 'tryst with destiny speech' analogy on my aforementioned thread, we (meaning me and many of my co-Skoda owners) are quite worried about the bad reputation that Skoda after sales has built for itself over the years. One clear case is of Mr. Harish which has gone awry (reference - http://www.team-bhp.com/forum/indian...d-4-years.html (Skoda dealer changes parts in my car = Consumer Court = Car not returned in 4 Years) ). There are several other threads especially on the concern for the "Ghost of Mechatronics" (http://www.team-bhp.com/forum/techni...hatronics.html (Skoda Woes And The Ghost Of The Mechatronics!!) ) especially the 7 Speed DSG that you put in your Petrol Superb's which has got a very high failure rate in India (Thank God, I opted for a Manual transmission Superb). Also people even started topics on guidelines to buy cars like Skoda and what to expect (http://www.team-bhp.com/forum/indian...opean-car.html (7 Simple Guidelines if you're buying a European car) ). That is not to say that there are no satisfied Skoda owners in India. There are many including me (up to now). But the ghost of our predecessors still haunts us. Whether we will get Toyota levels of after sales service or not with Skoda? Whether my fine running car will be ruined at the hands of ill-trained technicians the moment it enters your workshop here in Meerut (U.P.)? Whether I will be fleeced with high cost of spare parts once parts like clutch etc. give way after a few years? These are questions which always create a doubt in our mind about Skoda ownership in India. Now today morning I read an interesting article in the newspaper regarding "Skoda asking its senior officials to perform" (http://m.economictimes.com/news/news...w/16391807.cms ). Now this got me thinking, where has Skoda gone wrong that it has only 1% of market share even after being in the Indian market for 11 long years. It has solid products which are very luxurious and provide reasonable value for money (at least in the case of my Petrol Superb). As a recent Skoda owner I can tell you that you have to strengthen ONE THING and one thing ONLY. And that is your "AFTER-SALES-SERVICE", its quality and lowering its costs. This alone can allow you to garner the confidence back from existing and prospective Skoda owners. I visited your workshops/dealerships at Meerut and at Faridabad but NONE of them provided me the confidence that I (meaning me and my Skoda) will be well looked after once I need to go there, which is going to be soon in my case, as I am nearing 6 months of ownership (for the 6 month/7500km checkup). I hope you will take this letter in the positive spirit that it is written by a Skoda owner (and now a converted fan from Toyota) and you will take immediate corrective steps in this regards. Hoping to hear from you personally so that I can pass your point of view to the general public through forums like TeamBHP which will help in negating the bad image the company has built up over the years. Warm Regards DXXXXX KAILE MEERUT - 250001 (U.P.) Mobile: xxxxxxxxxx Email: xxxxxxxxxx |

If Skoda remains on this path, it's happier days ahead for it and us customers.... |
