Engine Dynamometer System for Dynamic Engine Investigations

不列颠哥伦比亚大学正在要求一个测功机系统来支持和扩大正在进行的发动机研究计划。这项研究计划的总体目标是通过减少内燃机的排放和燃料消耗来减少对环境的影响。使用所需设备的研究领域包括：1)系统级发动机研究，2)发动机瞬时运行，3)新型发动机传感器的开发，4)发动机控制和优化，以及5)可变气门驱动系统在先进发动机控制中的应用。此外，还需要进行内部实验，以便为火花点火发动机的详细燃烧建模工作提供验证结果。所有这些都需要一种适合多缸发动机动态运行的测试设备。 所需设备将利用不列颠哥伦比亚省大学现有的大量基础设施和设备，并可立即实施。预计在其预期寿命内，将直接使用该设备对60多名HQP进行培训，并通过获得使用该设备开发的实验数据或工具，间接受益于类似数量的设备。这些HQP将非常适合未来在内燃机、燃烧系统、仪器仪表、优化和控制系统开发领域的职业。

A dynamometer system is being requested to support and expand the ongoing engine research programs at the University of British Columbia. The overarching objective of this research program is the reduction of the environmental impact of internal combustion engines, through the reduction of their emissions and fuel consumption. The research areas of interest using the requested equipment include: 1) system level engine studies, 2) transient engine operation, 3) development of novel engine sensors, 4) engine control and optimization, and 5) application of variable valve actuation systems for advanced engine control. In addition, there is a need for in-house experiments to provide validation results for detailed combustion modeling efforts of spark-ignited engines. All of these require a testing facility suitable for dynamic operation of multi-cylinder engines. The requested equipment will utilize significant available infrastructure and equipment at the University of British Columbia and can be immediately implemented. It is anticipated that over its expected lifetime 60+ HQP will be trained directly using this equipment, and a similar number will benefit indirectly from this equipment through the availability of experimental data or tools developed using the equipment. These HQP will be well suited for future careers in the areas of internal combustion engines, combustion systems, instrumentation, optimization, and control system development.
