Volvo Penta has introduced the D17, its most powerful engine to date, and expanded its genset range. This new power generation engine offers an excellent alternative to other engines in its class with an exceptional power-to-weight ratio, delivered from the same footprint as its compact D16 sibling.
The D17 is a highly fuel-efficient 17-liter industrial genset engine that meets both current and future business needs. It offers up to 5% less fuel consumption per kWh than the D16, thanks to recent advancements in combustion technology such as the modernization of the fuel-injection system with a common-rail design. The D17 also provides the option of a viscous fan to further reduce fuel consumption and noise emissions.
Volvo Penta used the D16’s inline six-cylinder block as the starting point for the new design, maintaining the same basic footprint while enabling a larger bore engine and a 10% increase in maximum standby power over the TWD1645GE at 1800 rpm. Going forward, Volvo Penta plans to transition its power generation line-up to significantly lower emissions utilizing alternative fuels.
“Combining this with its dual-stage turbochargers means the D17 can provide much higher power from a smaller envelope, comparing favorably with larger alternatives, while offering the additional benefit of far more economical operation,” says Kristian Vekas, Product Manager at Volvo Penta. “To find something with equivalent power density, you’d have to look beyond automotive-based designs – which will likely add further cost implications.”
The D17 is a dual-speed engine (1500/1800 rpm) designed for both stand-by and prime-power generator sets. It is a versatile option suitable for a wide range of applications, especially where reliable back-up electrical power is essential. The engine meets the most-stringent ISO8528 G3 standard for load acceptance, ensuring it can rapidly meet power demand in response to a blackout. The D17’s low exhaust emissions meet UNECE REG 96 Stage 2 standards (equivalent to EU Stage II mobile off-highway requirements) and is certified for US EPA Tier2 Stationary Emergency, enabling its use for supplying a few hours of back-up power in highly regulated regions.
