摘　　要：为推进车用燃气加热器产品开发,规范产品性能及质量监管,以燃气特性、燃烧理论、噪声测试原理、现代控制技术等理论为基础,研究了国内外同类标准的排放、噪声、安全等指标及测试方法。研究发现,将过量空气系数为1时废气中CO、NOx、HC的体积含量作为排放指标,能够全面控制车用燃气加热器排放;采用GB/T3767—1996能够客观准确测试产品工作噪声,利用点火安全时间及熄火安全时间指标能有效控制产品的工作安全性。最后结合样机测试结果及国内外最新标准,确定了中国汽车行业标准《汽车燃气加热器》(QC/T769—2006)中的技术指标及测试方法。实际应用证明,该标准能够在安全性、电气特性、工作稳定性和可靠性等方面综合规范产品质量。In order to promote the product development of vehicle gas-fuel heater and standardize the product performance and quality supervising management, the theories of gas characteristic, burning theory, noise testing principle and modern control technology were referred, and the indices and testing methods of vehicle emission, noise, safety in domestic and foreign similar standards were studied. It is pointed that the emissions of vehicle gas-fuel heater can be controlled effectively when the volume contents of CO, NOx and HC in vehicle emissions are taken as emission indices and excess air coefficient is 1, the product noise can be tested objectively and accurately when GB/T 3767--1996 is adopted, and the product work safety can be effectively controlled when ignition security time and flameout security time are taken as control indices. According to prototype test result and the latest domestic and foreign standards, the technical indices and testing methods in Chinese automobile industry standard of vehicle gas-fuel heater （QC/T 769--2006） are established, so that the standard can synthetically standardize the product quality in safety, electric characteristics, stability and reliability and so on. 1 tab, 1 fig, 15 refs.
