论文已在中国上海举行的第27届CIMAC大会上发表。论文的版权归CIMAC所有。Medium Speed Engine development is facing big challenges regarding mechanical and thermal loading due to future market demands as well as reduced NOx, HC, CO and particulate emissions with- out drawbacks in fuel consumption/CO2emissions, engine reliability and cost. Depending on the engine size and the application (e.g. marine-propulsion, gen-set or railroad) and under consideration of different fuels,(e.g. distillate, heavy fuel oil, gas, al- ternative fuels)a variety of measures like flexibility in the injection-system combined with increased injectionpressure and variable valve-timing will have an impact on the engine development.2-stage turbo charging and waste heat recovering as well as possible exhaust gas recirculation(EGR) and exhaust after treatment systems will have to be considered. In order to investigate these different functional features, even beforea new multi cylinder engine will be available,a single cylinder test engine is the most efficient tool to support these developments. Not only combustion related is- sues can be investigated but also several cylinder individual mechanical and thermal-load related questionscan be tested. Such single cylinder engine investigations will shorten development time and cost, and will improve engine reliability right from start of market introduction of a new engine family. The paper will give an overview about the bore and stroke range which can be covered by the single cylinder engine family as well as a detailed description of the engine family capabilities, features, modularity.A further part of the paper will be an introduction of the variety of investigations which can be done by such a single cylinderengine. Finally development cost-and time-saving potential by use of single cylinder engine testing will be evaluated.
