The new prime mover platform is dedicated to cover future domestic transportation, industrial and power generation requirements, and is ZVESDA’s foundation for future business expansion into target export markets. With this in mind, the engine family specifications were aimed at multi-application coverage of the marine, power generation, mining and locomotive applications, developed for present and future, local and global emissions legislations, as IMO3, US EPA Tier 4 interim, and for future fuel diversity opportunities. The essential engine family orientation resulted in a carefully sized 3,1 Liter / cylinder, a versatile and modular product. Diverse, application-balanced, reliability-durability-driven power density specifications, going up to 138 kW / cylinder in the Marine yacht application, the wide rated output engine speed coverage of 1500 – 2250 rpm, the modern engine technologies and design features, as required by the diverse emission compliance scenarios, and the state of the art supplier base, are important characteristics of the new PULSAR engine family. The present paper describes the overall design and development process, as it is conceptualized, driven and executed by the combined project teams of AVL List GmbH and JSC ZVEZDA. Starting from application-specific targets, as overall installation dimensions, weight and efficiency targets, etc., the paper shows the main engine architecture and the essential features of the engine family. Details are shown, describing main engine components and systems, such as the compact crank case, with its two materials specification for different maximum cylinder pressures, the aluminum flywheel housing and the single aluminum water jacket for low engine weight, or the parallel valve pattern, crossflow, top-down cooling cylinder head concept. The employment of specific technologies such as turbocharging, fuel injection and emissions abatement technologies are discussed in the context of the engine family targets. The paper emphasizes the comprehensive front loading development process approach, the extensive CAE activity, which contributed essentially to components commonality and to the balanced engineering solution across applications and emission legislations. Finally, the paper touches upon the procedural and logistical aspects of first prototype engine series procurement and ends with the current development status and the outlook of the consequent activities.
