 PETER GRANQVIST, VOLVO PENTA’S NEW CHIEF TECHNOLOGY OFFICER, TALKS  
 ABOUT THE COMPANY’S LATEST STAGE V ENGINES AND SPECULATES ON  
 HOW THE TRIPLE REVOLUTIONS OF ELECTRIFICATION, CONNECTIVITY AND  
 AUTOMATION WILL HELP SHAPE THE POWERTRAINS OF THE FUTURE  
 What’s in an engine?  
 Traditionally one might have  
 said the important elements were  
 fuel lines, air intake, a combustion  
 chamber and pistons to transfer the  
 energy. But, increasingly, engines are  
 becoming far more complex than  
 that. With the advent of electric/ 
 hybridelectric systems, connectivity,  
 automation, and ever-tighter  
 emissions regulations the very  
 fundamentals of what makes an  
 engine are beginning to change.  
 It is into this world that Peter  
 Granqvist stepped a year ago when   
 he joined Volvo Penta as its chief  
 technology officer, although it wasn’t  
 all new to him. Granqvist brought  
 with him a wealth of experience   
 in the field, joining from Denso  
 Corporation, where he spent many  
 years developing advanced powertrain  
 solutions, with recent focus on  
 connectivity and automation. 
 “It was a really good fit, I think,”  
 Granqvist tells iVT, “because Volvo  
 Penta is on a journey now to, of  
 course, continue to develop  
 conventional powertrain solutions  
 with diesel engines, but also to move  
 into these new areas. I have  
 14 iVTInternational.com September 2019 
 background knowledge in both the  
 traditional and the new areas.” 
 In 2019 Granqvist has overseen  
 the launch of Penta’s Stage V range,  
 which will be on display at  
 Agritechnica in Hanover this  
 November. “Volvo Penta has created  
 a full range of engines for our OEMs,  
 that are all Stage V compliant,” he  
 says. “We have from five liters to 16  
 liters, and from 105 to 575kW.   
 “We are focused on total cost of  
 ownership, maximizing uptime for  
 our customers, and reducing fuel  
 and AdBlue consumption. Cooling  
 capacity is sometimes an issue. So  
 we have really tried to reduce the  
 cooling need and make our engines  
 more efficient. 
 “We have a close-couple DPF,  
 where the SCR would normally be,  
 and then we have the SCR a little bit  
 further from the engine because that  
 is technically possible to do. So we  
 think we have made it as easy as  
 possible for the OEM to install.” 
 Granqvist is grateful that Volvo  
 Penta has been able to draw upon  
 expertise from across the Volvo  
 Group – challenges experienced in  
 the on-highway segment with  
 Euro 6 regulations mirror some  
 aspects the demands of Stage V. 
 “To secure up time we have  
 focused a lot on trying to avoid  
 specific DPF regeneration periods in  
 the cycle the period where particles  
 are burnt off ‘cleanly’ from the DPF.  
 We have found a very sophisticated  
 way of getting high temperatures  
 into the DPF without having high  
 loads. So we avoid the operator  
 having to do a specific cycle. So –  
 and this may not be expected when  
 you go to Stage V – you save fuel.  
 We can actually save up to 5%,  
 depending on the application and  
 cycle. So it’s a very strong package.” 
 Looking to the future 
 Of course, Stage V is just the latest  
 small step on the road to a cleaner,  
 more efficient future for off-highway  
 engines. One that will involve  
 technological input from a wide  
 variety of disciplines. As CTO, it’s  
 Granqvist’s job to keep one eye on  
 where the industry is heading. 
 “There is a clear need, not only in  
 our business, but across automotive,  
 for cleaner power solutions,” he says.  
 “One way to achieve this is
