Audi TT engine range to be extended
The turbocharged 1.8TFSI has a displacement of 1,798cc and achieves its peak torque of 250Nm across the rev range of 1,250 to 5,000rpm. Uniquely, at part loads, an additional manifold injection system supplements the FSI direct injection, to cut emissions.
The Audi valvelift system varies the stroke of the exhaust valves, improving the engine’s response. A compact rotary valve module for thermal management and the exhaust manifold integrated into the cylinder head both play a major part in the four-cylinder engine’s efficiency.
