Company Audi is rapidly moving forward, extending the engine range. By the end of model year Audi A6 will be equipped with the new petrol engines of 2.8 liter, developing 154 kW (210 hp) and maximum torque of 280 Nm in the range 3000-5000 rev / min. In addition to technology, FSI direct injection gasoline V6, this is different for the first time used a highly efficient and at the same time, surprisingly simple technology of advanced valve control system Audi valvelift system. This system not only Audi drivers will get more pleasure from driving, but also save on fuel. The new system is designed for two-stage valve lift height adjustment. In contrast to conventional systems, requiring the introduction of additional components that need to switch or slide to be in the position, this system uses actuators installed directly on the camshaft. This decision has undeniable advantages in terms of configuration, valve lift curves. The system Audi valvelift system uses the base jaws, located on the camshaft and the intake valves are capable of moving in the longitudinal direction. They are equipped with two cams, located next to each other: one cam is designed for low altitude valve lift , the second - for a large. Thus, depending on the load on the engine intake valves are opened by means of roller valve lifters. Together with a number of measures to reduce friction at different sites and details of the engine valve control system Audi valvelift system improves fuel economy by 10% . A6 model with FSI engine of 2.8 liters, with sufficient supply of power and torque for any situation, consumes only 8.7 liters of gasoline over the combined cycle of motion. The new engine 2,8 FSI high technology in all. This status is confirmed by the developed by Audi technology of gasoline direct-injection FSI, which allows you to bring the compression to 12,0:1, which makes the process extremely efficient combustion. Solutions such as cast aluminum cylinder block, weighing only 33 kg, and a new oil pump with two stages of pressure, performance of which varies according to demand, continue to list new products of high-tech.
