Los Angeles Find: Audi 5.2L V10 FSI Engine
The Los Angeles Motor Show had just recently concluded and so automakers were able to showcase their concept vehicles and new models. Audi was included in the long list of automakers which presented their vehicles. One of the things Audi showcased during the event is its 5.2L V10 FSI engine, a powertrain capable of 450 horsepower and connected to a six-speed Tiptronic automatic transmission. This engine powers the Audi S6 and S8 sedans.
What makes this Audi engine different from its lot is that it has been incorporated with the FSI technology. FSI is what Audi calls its direct injection fuel delivery system and because this is the first time that the FSI technology has been mated to a ten-cylinder engine, Audi has become the pioneering automaker for that technology. When the engine is seen up-close one would see that the injector extends up to the left side of the combustion chamber. This way, the fuel is directly injected to the combustion chamber. It injects the fuel under extreme high temperature, making the fuel escape the injector nozzle as gas vapor. This setup makes the mixture of fuel and air in the chamber increased, thus there is a complete burn. Fuel economy will then improve, allowing the car to run at maximum power output.
The materials used for the production of the 5.2L V10 FSI engine are of premium quality, as this guarantees longer engine life and service. The engine’s crank-case is made with die-casted hypereutic aluminum alloy. This material also has reduced rates of the unwanted thermal expansion. Grey iron bearing bridges have also been cast into the crankcase to help in decreasing the thermal expansion. These also aid in keeping the crucial crankshaft bearing clearances as they decrease deflection under stress. Forged steel connecting rods and oil cooled aluminum pistons are also connected to the crankshaft . The exhaust valves have been made with sodium and the intake manifold with magnesium.
This Audi engine is packed with so much power, making it a race-proven package. It is also equipped with most of the modern and efficient technologies for internal combustion engines.
