All engines follow Audi’s downsizing principle. Engine - 4.2L V8 - B7 - 2005.5-2008 - S4 - Audi New German Performance JavaScript seems to The engines used in the A4 model series – four TFSI gasoline and six TDI units – combine sportiness and efficiency in a groundbreaking manner. The 2.0 20v is less boring but may develop a drinking problem.Audi & Volkswagen parts, performance, tuning, maintenance and service. The 1.6 16v is the least complex, cheapest to maintain, and the most boring option. Despite being a dated design, the 1.8T is probably one of the best petrol engines available in the Audi B7 chassis. The 1.8T engine can be tuned for a lot more power relatively easily.
At the same time, performance has increased with many of the engines.Audi A4 B8 1.8 TFSI Turbo Turbo Fuel Stratified Injection Petrol Engine ECU Unit Audi A5 1.8 TFSI Turbo Fuel Stratified Injection Petrol Engine ECU Unit 2008 to 2012 Genuine Used Bosch Basic Engine Calculator with part number 8K1 907 115 M and Bosch part number 0 261 S05 870 for sale R65 00 in excellent working condition.ECS News APR Stage 1 ECU Software Flash Tuning Audi B7 A4 2.0T FSI. CO 2 emissions have decreased by 11 percent on average across the board, with the individual reductions as high as 19 percent. The start-stop system is standard for all models. Even the entry-level four-cylinder engine produces 230 Nm (169.64 lb-ft) of torque.
Maximum torque of 320 Nm (236.02 lb-ft) is available at just 1,400 rpm and remains constant up to 3,700 rpm. The high-end four-cylinder unit has a torque curve similar to that of a TDI. The results are powerful performance and astonishingly low fuel consumption. Audi development engineers have thoroughly enhanced the four-cylinder unit and created new solutions regarding numerous aspects of engineering.
Audi B7 Engine Plus The Audi
These valves ensure that the engine oil heats up to its operating temperature soon after the vehicle is started they also maintain the coolant temperature, as per a given driving situation, between 85 and 107 degrees Celsius (185.0° F and 224.6° F). Both camshafts can be adjusted as needed, plus the Audi valvelift system adjusts the lift of the valves on the exhaust side to minimize gas exchange losses.The innovative thermal management system features a further innovation: Two rotating cores control the flow of coolant. The Audi engineers achieved new degrees of freedom when it comes to charging efficiency in the combustion chambers.
It accelerates the Sedan to 100 km/h (62.14 mph) in just 10.5 seconds and reaches a top speed of 208 km/h (129.25 mph), yet consumes just 6.5 liters of fuel per 100 km (36.19 US mpg) on average.The 2.0 TFSI, a born winner that was named Engine of the Year five times in a row from 2005 through 2009, is the mid-range gasoline engine in the A4 portfolio. Internal friction has also been significantly reduced by the use of an innovative coating on the piston skirts and by mounting the two balance shafts that provide for smooth operation in roller bearings.The regulated oil pump requires little energy itself, and a high-precision electric system controls the piston heads with jets of oil.The TFSI: from 88 kW (120 hp) to 200 kW (272 hp)The entry-level gasoline engine is the 1.8 TFSI with 88 kW (120 hp) and 230 Nm (169.64 lb-ft) of torque. Its most important innovation is an electric wastegate actuator that adjusts the boost pressure particularly quickly and precisely, optimizing engine response.Despite all the new technologies and the added performance, Audi has reduced the weight of the 1.8 TFSI from 135 to 131.5 kilograms (297.62 lb to 289.91 lb). The turbocharger is also a new development. This solution reduces the exhaust gas temperature.
Audi B7 Engine Manual Transmission And
The supercharger located in the 90-degree V of the cylinder banks is belt-driven by the crankshaft. Its average fuel consumption is 6.8 liters per 100 km (34.59 US mpg), which corresponds to 159 grams of CO 2/km (255.89 g/mile).Somewhat later, Audi will introduce the most powerful gasoline engine: the supercharged 3.0 TFSI. Paired with the six-speed manual transmission and quattro drive, it accelerates the A4 Sedan to 100 km/h in 6.5 seconds on the way to a top speed of 246 km/h (152.86 mph).
The A4 Sedan completes the standard sprint in just 5.9 seconds, and top speed is limited to 250 km/h (155.34 mph). It generates 200 kW (272 hp) and a brawny 400 Nm (295.02 lb-ft) of torque between 2,250 and 4,750 rpm. Adjustable intake camshafts and tumble flaps in the intake ports provide for good charging efficiency in the combustion chambers.Its willingness to rev, its pulling power and its cultivated, sonorous sound make the 3.0 TFSI a sporty and dramatic engine. An extensive array of measures makes the supercharger less noisy.A balance shaft in the engine’s light-alloy crankcase enhances smooth running. The gas travel paths behind the compressor are short so that torque is generated early and quickly. The compressor first compresses the intake air to as high as 0.8 bar before it is subsequently cooled down again by two intercoolers.The compressor is behind the throttle valve, which boosts the former’s efficiency.
With the fourth version, which has undergone a series of detailed optimizations, these figures are 120 kW (163 hp) and 380 Nm (280.27 lb-ft). The second variant puts out 100 kW (136 hp) and 320 Nm (236.02 lb-ft) the third 105 kW (143 hp). The first version delivers 88 kW (120 hp) and 290 Nm (213.89 lb-ft) of torque, the latter between 1,750 and 2,500 rpm. Audi offers five versions of it for the Sedan and the Avant. Their powerful performance, immense torque, low fuel consumption and cultivated operation combine for a harmonious overall impression.Even the 2.0 TDI is a powerful engine. A second version of the 3.0 TFSI, with 245 kW (333 hp), powers the S models.Powerful and highly efficient: The TDI enginesTDI engines from Audi stand not only for high efficiency, but also for a smart, modern type of sportiness.
In the Sedan the A4 2.0 TDI with 120 kW (163 hp) manages with 4.4 liters of diesel per 100 km (53. It boasts impressive performance, accelerating from zero to 100 km/h in 9.3 seconds on its way to 215 km/h (133.59 mph). The Sedan requires just 4.3 liters of fuel per 100 km (54.7 US mpg) on average – a CO 2 equivalent of 112 grams per km (180.25 g/mile). Fuel consumption decreases by as much as 0.2 liters per 100 km.The most efficient variant in the model family is the A4 2.0 TDI with 100 kW (136 hp). This makes the engine even smoother at low revs, which permits earlier upshifts and thus more efficient driving. The 2.0 TDI with 105 kW (143 hp) and 130 kW (177 hp) are also available for the A4 allroad quattro.The technical specialties of both four-cylinder diesel engines are the low internal friction, a turbocharger with adjustable vanes, and a new centrifugal governor in a dual-mass flywheel (in versions with 100, 120 or 130 kW ).Thanks to its sophisticated design, the flywheel only requires a slight mass to compensate for most of the vibrations caused by the engine.
