O νέος 122άρης (όπως και ο 140άρης) είναι αλουμινένιος και χρησιμοποιεί ιμάντα αντί για καδένα.
Έχεις κανένα πρόχειρο λινκ; Μου κάνει εντύπωση ο ιμάντας αντί καδένας...
Για τον ιμάντα:
'The overhead camshafts are driven by a single-stage, low-friction toothed belt design with a 20 mm wide belt and load-reducing profiled belt wheels.'

Γενικά:
'The EA211 engines are a completely new four-cylinder turbocharged and direct-injection TSI engines. Compared to its predecessor, the EA211 series is significantly more compact, with installation length 50 mm shorter, thus offering more interior space. The installation position of the engines has also been optimised. Just as in the diesels, the petrol engines are now mounted with the exhaust side facing backwards and tilted at an angle of 12 degrees. The weight of these petrol engines made of die-cast aluminium is only 97 kg for the 1.2 TSI and 106 kg for the 1.4 TSI. The crankshaft alone became lighter by 20 per cent; the connecting rods lost 30 per cent of their weight. In addition the connecting rod bearing journals are now hollow-drilled and pistons now come with flat bottoms, all of them optimized for lower weight. Regarding thermal management, the EA211 petrol engine is equipped with a modern dual-circuit cooling system. That means that a high temperature circuit with a mechanically driven cooling pump cools the basic engine, while a low temperature circuit flows through the intercooler and the turbo-charger casing. The cylinder-head circuit heats the cabin's interior. The exhaust manifold is integrated into the cylinder head, enabling the engine to warm up more quickly, in turn making heat available quickly for the passenger cabin. At high loads, the exhaust is cooled by the coolant, lowering fuel consumption.'
