TSI is a range of turbocharged direct injection gasoline engines produced by the German Volkswagen Group. The first TSI engine had a capacity of 1.4 liters and was first introduced in 2005 on the Golf GT Mk5. It was highly praised by experts and won the “Best New Engine” award in the prestigious “International Engine of the Year” competition. Today, models from brands such as Volkswagen, SEAT, and Škoda can be equipped with TSI engines. These engines develop high power and torque despite their relatively small capacity. They are characterized by fuel economy.
FEATURES
TSI engines have 4 cylinders with 8 or 16 valves. The engine block can be made of cast iron or aluminum. The cylinder head is always made of aluminum. The engine can be turbocharged or twin-charged. In the twin-charged version, the engine has both an exhaust turbocharger and a mechanically driven supercharger. The timing mechanism uses a chain or a belt, depending on the timing system version.
