Det finns ett  gammalt ordspråk inom motorutveckling som lyder ” Theres no replacement for displacement.” vilket fritt översatt betyder att man kan inte byta ut slagvolym och få en motsvarande effekt trots tekniska förbättringar.

Bigger the better

Detta stämmer inte längre. 2,7-liters motorn från Ford visar att man ny teknik kan man byta ut slagvolymen och ändå få en V6 i klass med en dubbelt så stor V8.

Ett paradigmskifte

CGI block and ladder-frame aluminum cradle support for the 2.7L EcoBoost V6′s bottom-end makes for a package similar in strength and durability to the Power Stroke diesel.

During Ford’s press briefing and walk-around earlier this week, I talked with Ed Waszczenko, the 2.7L EcoBoost’s lead engineer, who said customers are going to be “surprised by its performance.” With the numbers Ford has shown for this engine, I am sure they will. In addition to the CGI block, which doesn’t need cylinder sleeves like the aluminum-block 3.5L EcoBoost, Waszczenko pointed out the die-cast aluminum ladder frame cradles the block to form a very rigid and robust block assembly. That translates into durability over the long haul. He also directed our attention to the twin turbos and how they are mounted directly to the exhaust manifolds. That positioning, an EcoBoost trademark, allows for rapid spool-up and the ensuing flat torque curve reminiscent of a diesel. –
