GREENSBORO, N.C. -- Volvo Trucks is claiming customers will see 0.5-2% better fuel mileage when using its 2014 engines.
Trucks equipped with a Volvo D11, D13 or D16 engine will perform better, as a result of optimized and enhanced engine componentry, the company announced.
“Volvo Trucks is committed to designing and engineering fuel-efficient technology that offers our customers solutions to reduce their fuel consumption and positively affect their bottom lines,” said Goran Nyberg, president of Volvo Trucks North American Sales & Marketing. “Volvo trucks equipped with 2014 engine technology will deliver substantial fuel efficiency benefits, while also providing the power and performance customers expect from a Volvo powertrain.”
The fuel consumption improvements will result from multiple optimized or new components, the company claims. Among them are low-friction cylinder improvements, including a redesigned piston and liner developed with smoother surfaces, and a clutched air compressor, which completely disengages the clutch from the engine.
As well, a new seven-hold injector offers better fuel atomization for a more even distribution of fuel within the cylinder, Volvo says. Also new is a crankcase ventilation system that filters more oil from blowby gases before they leave the engine, while at the same time improving engine backpressure for better performance.
Volvo also has been in design changes to improve serviceability, including a new two-piece valve cover, which reduces repair time and is easier to handle than previous covers.
