【 摘 要 】

Task 1 was to design study for fuel-efficient system configuration. The objective of task 1 was to perform a system design study of locomotive engine configurations leading to a 5% improvement in fuel efficiency. Modeling studies were conducted in GT-Power to perform this task. GT-Power is an engine simulation tool that facilitates modeling of engine components and their system level interactions. It provides the capability to evaluate a variety of engine technologies such as exhaust gas circulation (EGR), variable valve timing, and advanced turbo charging. The setup of GT-Power includes a flexible format that allows the effects of variations in available technologies (i.e., varying EGR fractions or fuel injection timing) to be systematically evaluated. Therefore, development can be driven by the simultaneous evaluation of several technology configurations.
