Audi Has Launched Its Two-Liter Gasoline Engine

Audi has launched its two-liter gasoline engine that will be added in the new Audi A4 by the end of the year.

Audi Launches 2.0 TFSI Four-Cylinder Engine

The new 2.0 TFSI four-cylinder engine with 140 kW (190 hp) sports a new combustion method and weighs only about 140 kg (308.6 lb).

Drawing 140 kW (190 hp) of power and 320 Nm (236.0 lb-ft) of torque from a displacement of 1,984 cc, the engine also claims to consume lesser fuel. Its high torque is applicable to a wide speed range of 1,450 to 4,400 rpm.

Audi member of the board of management for technical development Dr Ulrich Hackenberg said: "We're now taking a crucial step further with rightsizing.

"Rightsizing thus involves the optimal interplay of vehicle class, displacement, output, torque and efficiency characteristics under everyday conditions. Our new 2.0 TFSI is a prime example of Vorsprung durch Technik."

The new engine utilises a new combustion method in which the intake time has been significantly shortened while the intake valve also closes earlier, leading to reduced medium pressure and a high, efficiency-boosting compression ratio.

In the partial load range, an additional injection upstream from the intake valve yields an efficient mixture formation that is already complemented by the direct injection in the intake manifold and in the combustion chamber, Audi said.

The Audi Valvelift System (AVS) on the inlet side also allows a short intake time at partial load and a longer time at higher loads.

Speaking about the advantages of the engine, Audi head of engine development Dr Stefan Knirsch said: "Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine.

"The result is optimal efficiency and performance characteristics across the entire engine speed range."
