FORD OTOSAN has developed new 7400 and 9400 Series ECOTORQ engines. The new series has 7.3 L and 9.0 L engines and replaces current 7300 Series Ecotorq engines powering Ford Cargo trucks since 2003. In this paper, new features of the engines are described. The engines have high peak fire pressure capability achieved by implementation of the new cylinder head gasket concept, and Compacted Graphite Iron (CGI) material for cylinder block and cylinder head. Parent bore power cylinder application together with new fine boring process brings low oil consumption and long engine life. Lateral cooling concept of the cylinder head provides both efficient cooling and higher cylinder head stiffness. Double stage oil pump used is a compact solution for the case where the part has challenging packaging limitations.
