Motor EA113 2.0 TFSI
The two-liter EA113 TFSI engine appeared in 2004. It was designed on the base of naturally aspirated engine VW 2.0 FSI with direct fuel injection. The main difference between two engines is letter T, which means - turbocharged.
That is not the only one difference, of course. The engine was reinforced to maintain a higher power. 2.0 TFSI engine has cast iron cylinder block instead of aluminum block. Inside the new engine block, there are two balancing shafts, another more sturdy crankshaft, new pistons and connecting rods for lower compression ratio. There is 16-valve twin-cam cylinder head mounted on top of the block. The cylinder head got new camshafts, valves, reinforced valve springs. The 2.0 TFSI is equipped with Variable Valve Timing system for the intake camshaft only, direct fuel injection, hydraulic tappets.
The engine uses the small turbocharger BorgWarner K03 (max pressure is 0.6 bar), which provides high torque already from 1800 rpm. More powerful engine versions are equipped with a high-performance turbocharger - KKK K04.
