Development of an Undergraduate Internal Combustion Engine Facility

密苏里大学罗拉分校目前正在计划调整机械工程专业的内燃机课程。该项目的目标是通过介绍与发动机工业当前的创新和激励因素有关的讲座主题和实验室经验，包括现代空气和燃料进气系统、排放形成和排放测试和要求，使课程现代化。将为工业界捐赠的最先进的发动机开发现代化的火花点火发动机测试设备。测试设施将充分自动化，使学生能够专注于测试过程中获取的数据，而不是发动机的控制。所需设备包括测功机控制系统、基于PC的数据采集系统和一些发动机仪表。测功机控制系统将保持发动机扭矩和速度设定值，而不需要连续调整，并提供安全、快速的设置点变化。学生将使用高速数据采集系统收集对当前设计至关重要的发动机信息，包括发动机负荷和速度、燃烧室压力分布、燃油喷射特性和废气排放。预计该项目将激发更多学生对内燃机领域的兴趣，并培养出能够更好地服务于工业需求的学生。

A plan is currently under way to restructure the internal combustion engine curriculum for Mechanical Engineering at the University of Missouri-Rolla. The goal of the project is to modernize the course by introducing both lecture topic and laboratory experiences pertaining to current innovations and motivating factors in the engine industry including modern air and fuel induction systems, emission formation and emission testing and requirements. A modern spark ignition engine test facility will be developed for a state-of-the-art engine donated by industry. The test facility will be sufficiently automated to allow the students to focus on the data being taken during the testing and not on the control of the engine. The needed equipment includes a dynamometer control system, a PC base data acquisition system and some engine instrumentation. The dynamometer control system will hold the engine torque and speed set points without requiring continual adjustment and provide safe, rapid change of set points. The students will collect engine information that is crucial to current designs including engine load and speed, combustion chamber pressure profiles, fuel injection characteristics and exhaust emissions using the high speed data acquisition system. It is anticipated that this project will generate more student interest in the area of internal combustion engines and produce students that are better able to serve the needs of industry.
