Sandvik introduces Toro™ TH551i with Stage V Engine

Sandvik has introduced a new 16-litre Stage V engine option for its Toro™ TH551i 51-tonne i-series truck. Volvo Penta’s 585kW output engine allows higher speeds and improved productivity in demanding conditions and fits together with the underground truck design.

The company stated that with its new Stage V engine option, Toro™ TH551i offers more power and speed compared to the 515 kW Tier 4i predecessor, shortening cycle times. As the engine output power exceeds 560 kW, instead of fitting the truck with a diesel particulate filter, other means are utilized to reduce emissions: the truck exhaust after treatment system contains a Selective Catalytic Reduction system (SCR) that uses diesel exhaust fluid to reduce emissions of NOx without sacrificing performance or fuel efficiency. The common rail injection and dual-stage turbo charging provide high power density, low fuel consumption, low noise and low emissions. Further, optimal cooling solutions in the engine minimize parasitic energy losses.
