Abstract The Legacy engine is a new core technology that can be used with existing infrastructure providing for near term benefits while minimizing costs. Also, as a new technology, it will be optimized for many years to come providing the opportunity for continued environmental and economic benefit for the United States. Utilization of the Legacy engine will reduce Greenhouse Gas (GHG) emissions and our dependence on foreign oil, provide the United States a technological advantage in a critical market, and create thousands of green jobs. For the Legacy engine to achieve the predicted benefits, optimization of induction and exhaust in the engine is critical. The continued research and development will result in a commercially viable Legacy engine. The development of an aspiration plate with optimal port geometry is the technical challenge that is addressed in the project. This project consists of design, manufacturing, testing and evaluation of port configuration for the Legacy engine aspiration plate. The results of this research will allow for the continuing development of the Legacy engine. Both inline and counter-rotational flow concepts were investigated. Two aspiration plates were designed and evaluated. Based on the results of the tests, a third aspiration plate, with optimal port geometry was designed and evaluated.
