432 072 With the 1.4l TFSI engine, Audi introduces a modern power plant for the entry level segment. The new engine has been systematically developed according to the so called downsizing concept . It represents a major step towards the development of more fuel efficient and cleaner engines. In specific terms, this means that non charged engines will be replaced by smaller, turbocharged units. The aims of downsizing are, above all, to reduce overall weight, to minimise friction, to improve fuel efficiency, to achieve lower exhaust emissions and, of course, to create a more compact engine that requires less space. This, in turn, has further advantages in terms of the utilisation of space in the vehicle. The 1.4l TFSI engine was developed by Volkswagen in association with Audi and will be used throughout the Group. The basis for the joint development project was the 1.4l TSI engine with dual charging by Volkswagen. The new 1.4l TFSI engine will be used on the Audi A3 and A3 Sportback. It is positioned between the 1.6l MPI engine 75 kW and 1.8l TFSI engine 118 kW . With a maximum power output of 92 kW 125 bhp , peak torque of 200 Nm and exceptional fuel efficiency for an engine of this size, customers can look forward to a powerplant that combines performance and economy. The 1.4l TFSI engine combines with a long throw 6 speed manual gearbox or the 7 speed twin clutch gearbox to create a compelling powertrain concept that offers driving enjoyment without any regrets. 432 071 The objectives of this Self Study Programme In this Self Study Programme you will learn about the design and operation of the 1.4l TFSI engine. Once you have worked your way through this Self Study Programme, you will be able to answer the following questions How is the engine designed mechanically How does the oil supply system work What are the special features of the air supply system How does the cooling system work, and to what should atten
