The cost per gram CO2 saving is a main factor for a sound business case with regard to a Diesel powertrain satisfying emission regulations and power requirements. The use of such powertrain concept in multiple vehicular platforms including a wide range of inertia classes increases the complexity of the decision matrix. It becomes even more complex if the matrix contains both passenger car and commercial vehicle applications, as the buying motivation for the wide customer range can be quite different. The engineering challenge is to outlay a modular powertrain design which can be tailored for the specific platform requirement and at the same time reduce the complexity associated with modularity. This paper addresses a system approach, suggesting the coupling of feed-gas emission/thermal capabilities and the after-treatment system requirement for a wide vehicle platform range. Based on a pool of variations in engine settings, an optimization scheme is used to identify the constrained optimal settings for cold, warm, and hot engine operation coupled to the thermal evolution of the considered after-treatment system. The dependency of the system attributes is demonstrated for light to heavy inertia platform classes, complying with legal emission limits for light duty to passenger car applications. The trade off for cost per gram CO2 is outlined as a function of the different hardware variants and the required after-treatment system.
