Not exact matches
an added benefit of the lead in the fuel was
cooler temperatures at the exhaust valve meaning they could mmachine the exhaust valve seat right out of the existing cast
iron of the
cylinder head.
Speaking about innovations and new features we should also mention cast
iron sleeves in block of
cylinders as well as second phase shifter on the Double - VANOS exhaust valve along with 244/228 duration camshafts, new pistons and connecting rods, intake manifold, renewed
cooling system and electronic throttle body.
There's a cast
iron block complete with water jackets between each
cylinder to achieve optimal
cooling.
Engine Structure: Two - stroke, aluminium
cylinder head, cast

Additional engine features:
Iron cylinder block and aluminum DOHC
cylinder head Forged steel crankshaft and connecting rods Oiling circuit that includes a dedicated feed for the turbocharger to provide increased pressure at the turbo and faster oil delivery Piston -
cooling oil jets 16.5:1 compression ratio Common rail direct injection fuel system Ceramic glow plugs for shorter heat - up times and higher glow temperatures Balance shaft that contributes to smoothness and drives the oil pump Laminated steel oil pan with upper aluminum section that contributes to engine rigidity and quietness B20 bio-diesel capability The Duramax 2.8 L is the cleanest diesel truck engine ever produced by General Motors, and meets some of the toughest U.S. emissions standards, thanks in part to a
cooled exhaust gas recirculation (EGR) system.
Unique cast pistons travel within
iron cylinder liners, and are
cooled by oil squirters and affixed to forged connecting rods for high - revving reliability.
The aluminum sleeves provide better
cooling, thus allowing closer piston - to -
cylinder clearance than
iron liners afford.
