Tupy to Produce CGI Diesel Engine Castings for Nissan


The Tupy foundry in Brazil will produce a compacted graphite iron (CGI) cylinder block for the new Cummins Inc., Columbus, Ind., U.S., 5.0L V8 turbo diesel engine. Cummins has indicated the engine will be available not only for Nissan’s next-generation Titan full-size pickup but recreational vehicles and commercial vehicles. Like the current model, the truck will be built at Nissan’s Canton, Miss., vehicle assembly plant and its gasoline engines will be cast, forged and assembled at Nissan’s Decherd, Tenn., powertrain plant.

“With approximately 50% of the U.S. market share being held by pickups, SUVs and crossovers, the increased use of diesel engines provides an important contribution toward helping OEMs meet the continual increase in [fuel economy] standard increases from 27.5 miles per gallon (8.6 litres/100km) in 2010 to 54.5 mpg (4.3 litres/100 km) in 2025,” said Dr. Steve Dawson, president and CEO, SinterCast, Stockholm. SinterCast supplies the process control technology for Tupy’s high volume CGI production.

CGI offers high tensile strength, stiffness and fatigue strength vs. grey iron or aluminium. With a torque rating in the mid-500 lb.-ft. and more than 300 horsepower, the Cummins 5.0L V8 Turbo Diesel will provide light truck customers with a combination of towing capacity and mileage.
