Sandvik Introduces a 16-liter Stage V Engine for the Toro TH663i Truck

Sandvik has released a new engine option for its largest truck, Toro TH663i. This fuel-efficient 16-liter Stage V engine from Volvo Penta is powerful and reliable, delivering 585 kW output. The engine and the truck have been designed to work together seamlessly, for performance in underground mines.

Technology for reduced emissions, without sacrificing performance or fuel efficiency

The Toro TH663i truck’s Stage V engine is designed to meet the requirements for non-road engines in the power range over 560 kW. In this power range, instead of fitting the engines with diesel particulate filters, other means are utilized to achieve reduced emissions. The Toro TH663i truck engine’s exhaust after treatment contains a Selective Catalytic Reduction system (SCR). The SCR uses diesel exhaust fluid to reduce emissions of NOx without sacrificing the truck’s 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. The Toro TH663i Stage V engine system is not equipped with a diesel particulate filter, simplifying the system. 

Further emission reduction through use of renewable paraffinic diesel fuel

The new Stage V engine option requires ultra-low sulphur fuel and low-ash engine oil to operate. However, in addition to running on traditional fossil diesel, the Toro TH663i truck can also use paraffinic diesel fuels that meet the requirements of the EN 15940 standard. Renewable paraffinic diesel fuel considerably reduces greenhouse gas footprint and the emissions of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC), nitrogen oxides (NOx) and diesel particulate matter (DPM) in the engine exhaust. The truck can use different blends of fossil diesel fuel and paraffinic fuel without limitations. There are no precautions or pre-work required when shifting from fossil to paraffinic fuel, which makes it flexible and user friendly.

Continuous development of the flagship truck

During the past a couple of years, the Toro TH663i truck has benefitted from several significant improvements. In 2019, Sandvik introduced a new transmission to increase productivity, improve reliability and reduce truck operating costs, as well as a new durable and maintenance-friendly cooler with outstanding corrosion resistance and long component lifetimes. Last year brought updates to the truck’s automation performance, as Sandvik’s AutoMine offering introduced its AutoMine for Trucks, enabling autonomous truck haulage not only underground but also on the surface, which is an inevitable part of a truck’s normal duty cycle at numerous mines.'
