TFSI
Audi TFSI Engine
Audi was the first car manufacturer that started combining turbo-charging with petrol direct injection in large scale car manufacturing. The journey of 2.0 Audi TFSI(Turbo Fuel Stratified Injection) engine began in the summer of 2004, as the same year it was attached to the Audi A3 Sportback. It became a huge hit. Why shouldn’t it be so! A turbocharged direct-injection four-cylinder engine ate up 10 to 15 % less fuel, compared to the conventional V6 engines.
Turbo-charging and TFSI technology make an excellent combination as fuel evaporation inside the combustion chamber in TFSI engines removes heat from intake air. Naturally, higher compression improves engine efficiency. This solved the problem of knocking at high boost levels in turbocharged engines.
Integrated turbocharger exhaust module creates optimum level of turbine efficiency. This resulted in marvelous utilization of exhaust energy. This helps availing a high power output and maximum engine responsiveness. The ultimate goal is to reduce exhaust emission and fuel consumption.
2.01 TFSI, the second generation Audi TFSI engines were introduced in the Audi models like, A5, A4, Audi Q5 in the year 2008. This featured for the first time, valve-lift system on the side of the exhaust. This resulted in a low-end and very effective dynamic torque build-up. Performance got improved with taller gear ratios and a considerable amount of reduction in fuel consumption.
A combination of mechanical super charging module and a petrol direct injection makes a 3.01 V6 engine fitted to a few Audi models. This is a power plant with the maximum torque of 400 Nm with moderate amount fuel consumption. Audi TFSI engine unlocks greater power output and extraordinarily dynamic performance without much fuel consumption.
