Engine mechanics The 2.0l/110kW FSI engine with 4-valve technology The 2.0l/110kW FSI engine was used in the Audi A3 in February 2003. Volkswagen used the engine for the first time in October 2003 in the Touran. It will be available for the Golf from the start of 2004. Technical features ● Single-piston high-pressure pump ● Plastic variable intake manifold ● Intake manifold with continuously adjustable charge direction flaps/ intake manifold flaps ● Water-cooled exhaust gas recirculation valve ● Roller rocker finger with hydraulic support element ● Two overhead camshafts with continuous inlet camshaft adjustment ● Balancer shaft gear assembly in sump ● Air-guided combustion method S322_011 Technical data Torque and power diagram Engine code AXW Type 4-cylinder in-line engine Displacement [mm³] 1984 Bore [mm] 82.5 220 200 180 110 100 90 Stroke [mm] 92.8 Valves per cylinder 4 Compression ratio 11.5:1 Maximum output 110kW at 6000rpm Maximum torque 200Nm at 3500rpm Engine management Bosch Motronic MED 9.5.10 Fuel Unleaded 98 RON (Unleaded 95 RON with reduction in performance) Exhaust gas treatment NO x storage catalytic converter and 2 starter catalytic converters Emissions standard EU 4 Torque [Nm] 160 140 120 100 80 60 40 20 1000 3000 5000 Engine speed [rpm] 80 70 60 50 40 30 20 10 7000 Power [kW] S322_012 6
Intake manifold with change-over barrel The two-stage variable intake manifold helps provide the required power and torque characteristics. The pneumatic switching of the change-over barrels from torque to power position is map-controlled. The load, speed and temperature are the relevant variables for this process. Change-over barrel The change-over barrel in power position. The engine draws in air via the power channel and the torque channel. Power channel S322_065 Torque channel The change-over barrel in torque position. The engine draws in air only via the torque channel. S322_067 7
