54 www.coalage.com June 2016 engine technology continued • New water-cooled turbocharger. • New fuel injectors and more efficient combustion. • Engine brake employing Volvo Group patented technology, offering 250-kW performance and tenfold higher engine brake capacity. • Increased torque and torque curve. • Electronically controlled wastegate, en- hancing the engine's overall capabili- ties for mobile, high altitude and sta- tionary applications. • An emissions reduction system that does not need Exhaust Gas Recircula- tion (EGR). • Engine control unit (ECU) and electri- cal interface similar to the latest Stage IV/Tier 4 Final engine, enabling ease of installation. • Upgraded engine management sys- tem. • The highest output per liter of displace- ment in its class. • Heavy-duty cooling packages, retard- er thermostat housing, and a rear power take-off. Naval Singh, Volvo Penta's global seg- ment specialist in mining and construction, said, "To keep the commonality of parts in customers' installations, we followed the same engine footprint as the previous mod- el as far as possible. For example, this new 16-liter TAD1643VE-B shares common elec- trical and physical interfaces with Stage IIIA, Stage IV and Tier 4 Final engines. "We have seen substantial fuel sav- ings during a long field trial period. Also, service intervals are longer, which means less downtime and more productive time available with machines," he added. Volvo Penta also announced it has ap- proved the use of hydrotreated vegetable oil (HVO) fuels in all of its engines globally, en- abling a potential reduction of fossil CO 2 emis- sions by up to 90%. According to the company, its engines do not need any type of approval or specific certification for HVO usage. HVO is a paraffinic fuel, also known as synthetic diesel, which can be produced from a variety of vegetable and animal sources. Re- gardless of whether it is used "neat" or blend- ed with conventional diesel fuel, it can be used in any Volvo Penta engine without mod- ifications. Additionally, there are no changes needed to service intervals and normal war- ranty conditions are applicable. Fitting In Cummins has eliminated the need for EGR on its latest generation of ul- tra-low-emissions engines built to meet the Stage V rules and spanning the 100– 430 hp range. "Removing EGR allowed us to realize the full potential of the engine for Stage V without increasing displacement size. Our 12-liter QSM12 Volvo Penta's new 16-liter engine, the TAD1643VE-B shown here, has been tested in un- derground mining mobile equipment applications.
