Volvo launched its Tier 4 Final technology – which includes its
D4, D6, D8, D11, D13 and D16 diesel engines – at ConExpo-

savings compared to previous models, feature selective catalytic
reduction (SCR) technology cooled external exhaust gas recir-
culation (CEGR) that are designed to reduce NOx levels by 80
percent compared to Tier 4 Interim. The new engines power
the company's G Series articulated haulers, G946C motor
grader and H Series wheel loader.

swing SY16C has
an operating weight
of 3,858 pounds; a
