Independent engine manufacturer VM Motori SpA of Italy has awarded the Tupy foundry of Brazil, the world’s leading CGI producer, a series production contract for the cylinder block and bedplate of its new A 630 DOHC 3.0-liter V6 diesel engine. The CGI cylinder blocks and bedplates began series production at the Tupy Joinville foundry during mid-2010 using the SinterCast process control technology.

Following pre-machining of the cylinder blocks and bedplates at Tupy, final machining and engine assembly is performed in a purpose-built manufacturing facility at VM Motori in Cento, Italy. The Euro 5 compliant engine is capable of 240 hp (59 kW/liter) and 550 N·m (406 lb-ft) of torque and will be available in the 2011 model year vehicles in the European market.
Technical features of the engine include a chain-driven, double overhead camshaft with four valves per cylinder. Each valve is driven by finger followers. Each cylinder has a central direct injector with cooled EGR (exhaust gas recirculation) as an integral part of the cylinder heads. The vacuum pump is incorporated into one of the camshafts for greater efficiency and the oil pump is a rotary vane type.
Additionally, the engine’s packaging means that it can be fitted into tight engine bays.
The new V6 cylinder block and bedplate represent Tupy’s sixteenth and seventeenth CGI components to be launched into series production, while VM Motori becomes Tupy’s seventh CGI customer, according to Luiz Tarquínio, President and CEO of Tupy.
Tupy’s main customers include Chrysler, Cummins, Daimler, Ford, General Motors, Volkswagen, Audi, Perkins, International Truck and Engine, Mack Trucks, MAN, Diesel, Iveco, Kubota, John Deere, Bosch, Ambrake, Peugeot and other premier automotive and diesel engine manufacturers.
