9362022 Murphy The objective of this project is to evaluate a concept for reducing the pollutants emitted by internal combustion engines during the period before the engine reaches its optimal operating temperature. In this approach, a method is proposed for rapidly heating the catalytic converter by bleeding hydrogen into the exhaust system upstream from the catalytic converter. The hydrogen is produced by electrolysis of water using energy from the vehicle's battery and alternator. This is a Phase I award based on a proposal submitted in response to NSF 93-18, Small Business Innovation Research (SBIR) Program Solicitation. The results may potentially be applied to design of internal combustion exhaust systems to reduce pollutants emitted during start-up to levels produced when the engine and exhaust system are at their normal operating temperature.

该项目的目的是评估在发动机达到最佳工作温度之前减少内燃机排放的污染物的概念。在这种方法中，提出了一种通过将氢排放到催化转化器上游的排气系统中来快速加热催化转化器的方法。氢气是利用汽车电池和交流发电机的能量对水进行电解而产生的。这是根据NSF 93-18“小企业创新研究（SBIR）项目招标”提交的提案而获得的第一阶段奖励。研究结果可能应用于内燃机排气系统的设计，以减少发动机和排气系统在正常工作温度下启动时排放的污染物。
