The new Renault-Nissan V6 dCi Diesel Engine

An account is given of the development of the top end Renault V6 dCi 235 diesel engine which has been driven by requirements for exceptional handling and acoustic quality whilst meeting future emissions regulations. The engineering goals are listed and the design and development of the engine outlined. The cylinder module of the 4-cylinder 2.0 litre dCi engine is carried over and the use of a 65 degree V angle results in a compact 6-cylinder version. Full load performance and driveability and the reduction in structure-borne and air-borne vibrations are discussed. Fuel consumption and carbon dioxide emissions are considered. Elements that have been refined include an idle speed of 650 rpm, an overcooled exhaust gas recirculation system and a reduced catalyst soot filter regeneration penalty. A Laguna with a V6 dCi 235 engine and AJO automatic transmission achieves 192 g/km in the 1700 kg inertia class. The combustion chamber design and aftertreatment system are described in more detail and quality and reliability measures noted.
