The 1.4l 136kW TFSI engine is a top of the range addition to the In the Audi A1, the engine consumes on average just 5.9 litres of Audi A1 series. fuel per 100 km. Specifi c power output is 97.8 bhp per litre, yet The combination of a Roots blower and exhaust gas turbocharging CO emissions are only 139 g/km. 2 is refl ected in spontaneous throttle response and high pulling power, even at high driving speeds. Petrol direct injection, the Roots blower and the turbocharger The Roots blower cuts in at 1500 rpm and, in most situations, cuts make for a perfect combination. The engine is rated for a high out again at 2400 rpm. compression ratio of 10.0 1. This enhances thermodynamics, At the latest by 3500 rpm, the turbocharger does all the work. resulting in increased power output and economy. Since it has little work to do at low engine speeds, the Roots The three door Audi A1 with 1.4l 136kW TFSI engine sprints from blower is large in size and designed for high effi ciency. zero to 100 kph in 6.9 seconds and has a top speed of 227 kph. Thanks to TFSI technology, which combines effi ciency and dynam ics, all Audi models featuring the new 1.4l 136 kW TFSI engine continue Audi s successful concept of downsizing . 491 002 Learning objectives of this Self Study Programme In this Self Study Programme you will learn about the technology How is the basic engine designed of the 1.4l 136kW TFSI engine.
