Engine (B5244S4; B5254T3; 2006-2007): Design: Engine
The entire engine is made of aluminum.
The compact "pent roof" design of the combustion chamber and the V shaped arrangement of the valves optimize injection and evacuation via the intake passage and combustion chamber (cross-flow) and the exhaust passage. The swirl surfaces of the combustion chamber and the centrally positioned spark plug ensures optimal combustion, low sensitivity to knocking and low, stable exhaust emissions.
The pendulum suspension of the engine consists of an engine pad secured to a side member. The cylinder head is "gravity" cast which is a slower process than press casting. This is so that the exhaust and intake ducts and the water and oil mantles are integrated during construction.
Applies from 2006 model year
The engine meets Euro 5 emissions standards.
All bearings are lead free. The screws used are Crome 6+ free.
