MUNICH - 1.8 TFSI claimed to be very efficient to produce 170 horsepower and 236 lb.ft. (320nm). While able to achieve fuel consumption figures liter/100km 05.07 (41.27 U.S. mpg). Consumption was reduced by 21 percent compared with the previous model engine.
Audi has just released the 1.8 TFSI engine components. The machine will be installed in the Audi A5 family. With a turbocharged four-cylinder petrol, 1.8 TFSI engine in the base alloy of Europe.
With manual transmission, 1.8 TFSI accelerates to the speed of the Audi A5 Coupe from 0 to 100 km / h (62.14 mph) in 7.9 seconds. While the maximum speed the car reaches 230 km / h (142.92 mph). And 134g/km CO2 emissions produced.
Arson became a particular focus of this machine. In addition to direct injection FSI, 1.8 TFSI also used indirect injection. This system injects fuel at the end of the intake manifold near the valve furthest, which will rotate intensively with the air.
This reduces emissions and fuel consumption, the particles are designed such that the four-cylinder engine is in conformity with the limits of the Euro 6 standards. Unfortunately not apply until 2015.
To further optimize gas exchange, the valve control system has been given greater freedom to operate. Audi valvelift system, adjust the valve lift in two stages. Both camshafts can be adjusted through 30 or 60 degrees of crankshaft angle.
The pressure of the FSI system has increased from 150 to 200 bar. Injection system is activated immediately when starting at a higher load. It can do two or three individual injection operations per cycle.
