Development of Engine Test Bench for Catalytic Converter Evaluation

本文介绍了开发催化转化器在发动机台架上评价试验装置的必要性,列出了催化转化器进行发动机台架评价试验的基本内容,然后着重介绍了催化转化器活性(净化性能)评价试验装置、快速老化试验和机械特性评价试验装置的研制原理、基本结构和技术关键,最后介绍了实际应用效果。

The necessity of development of engine test bench for catalytic converter evaluation is first presented in the paper. Based on the evaluation test items listed in the paper, some special devices are developed for evaluation tests, including tests on A/F ratio, light-off temperature, accelerated aging test, hot vibration test, etc. The principle, structure and key technology of those devices were illustrated in the paper. Finally some test results were given.
