Tupy får pris från VW

Tupy Receives Award From Volkswagen

July 23, 2014

Iron block and cylinder head maker Tupy, Joinville, Brazil, received the Volkswagen Group Award this year. The trophy was presented at the Porsche plant, in Leipzig, Germany, and recognized the best global suppliers of all the companies of the Volkswagen Group. It honored global suppliers that fulfilled the expectations of product development, innovation capacity, quality and effectiveness serving the group’s different plants. The executives of the German group emphasized the synergy with their supply chain as a basic factor in the search for new technologies and innovations.

“This recognition strengthens our partnership and shows our commitment to product excellence, delivery and service towards one of our main customers,” said Fernando Cestari de Rizzo, vice president, Automotive Business Unit, Tupy.

Engine blocks and cylinder heads, in addition to other Tupy engineering parts supplied by the Brazil and Mexico plants, are present in Audi, Porsche and Volkswagen cars, as well as in VW, MAN and Scania trucks and buses around the world.



Brühl är också tillverkare av det aktuella blocket men de lär inte få motsvarande pris eftersom deras produktion med hemmakok håller inte så god kvalitet. Kassation förekommer för ofta hos Brühl

Hur man får en V6a på 2,7 liter att ha kraft som en V8 på ca 5 liter

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



Ford 2.7L EcoBoost V6 design rendering

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. –
