随着排放法规的日益严格和世界各地用户环保意识的提高，各汽车制造商和研究机构对减少排放进行了积极的研究。本文对溶胶-凝胶型TiO_2传感器进行了测试，以评估其在受控环境和火花点火发动机上的可靠性和燃烧传感器性能。在真实的火花点火发动机上进行了烟气中单一气体组分对二氧化钛传感器响应的影响及传感器性能评价的实验研究。获得更高的响应氧和氮氧化物，而不是CO2和CH 4。因此，TiO 2传感器对混合物的第一组分更敏感，并且在发动机台架上观察到良好的响应时间。© 2004 Elsevier B. V.保留所有权利。
Increasingly strict emissions regulations and heightened environmental awareness on the part of users around the world have led to energetic research into emissions reduction by various automobile manufacturers and research institutes. In this paper we tested sol-gel TiO2 sensor in order to evaluate the reliability and combustion sensor properties in controlled environment and on spark ignition engine. Experiments were carried out for understanding influence of single gas component of flue gas on the response of TiO2 sensor and evaluate transducer behaviour on real spark ignition engine. Higher responses were obtained for oxygen and nitrogen oxide, rather than CO2 and CH4. So TiO2 sensor was more sensitive towards the first components of mixture, and good response times were observed on engine bench. © 2004 Elsevier B.V. All rights reserved.
