基于中国大学生方程式规则要求,为国产LD450单缸发动机做增压化,并对其所选用的涡轮增压器进行仿真测试。以增加发动机的转矩和功率为目的,并将发动机热效率提高5%至8%。本文阐述了涡轮增压发动机的发展历程,接着分析了实现增压化所需克服的技术难点。本项目所使用的LD450发动机已经可以通过ECU实现对所有传感器和测试系统的控制,主要使用了CW160电涡流测功机,GTE100冷却塔,FST3发动机数控测试平台以及其他发动机台架测试所需的设备。根据规则,进入发动机气缸的空气必须流经一直径为20m m的限流阀。对发动机喷油量和点火提前角进行了重新标定,并使用AVLBOOST软件对增压后的发动机进行了仿真。本文阐述了涡轮增压器的基本选择方式和尺寸大小,通过分析实验数据来得到增压后发动机的性能参数。在分析模拟和实验结果后,可以说功率和扭矩增加了。在7000rpm时,扭矩从42Nm增加到大约46Nm,功率从32kw增加到大约35kw。如果它可以避免实验损失,则可以获得更多的功率和扭矩,并且可以提高效率。
