This SAE Recommended Practice establishes performance guidelines for the capacity of the air reservoir systems used on trucks, towing trucks, truck-tractors, trailers, and converter dollies with GVWRs over 10 000 lb, designed to be used on the highway. NOTE: Compliance with this document does not guarantee compliance with the air reservoir requirements of FMVSS 121. The purpose of this document is to establish a minimum air storage capacity for highway-type trucks, buses, trailers, and converted dollies which use compressed air to actuate or transmit actuation power to the foundation brakes. A vehicle's air reservoir capacity is quantified by its ability to provide a brake application pressure which is adequate to stop the vehicle within the emergency brake stopping distances specified in Table II of FMVSS 121, after seven full brake applications with the air compressor disabled.

各加气站按照GB18047《车用压缩天然气》标准对天然气进行净化之后,提供 CNG中的硫化氢和微量水容量甚低,而 LNG中的甲烷也是在 95%以上,硫化氢含量低于 4ppm。可见二者在理化性质和热值等指标方面十分接近。2 、用作发动机燃料,其动力性、燃料经济性和尾气排放方面,CNG和LNG十分接近,并无明显区别。3 、进入发动机气缸前的供气压力、流量、混合比等方面技术要求都相同。...
对SAE测试,压缩空气供给必须用3/4英寸(16mm)或更高的管道直径;对VAD测试,则需要1/2英寸(12.7mm);对SAE测试的压缩空气供应内径3/4英寸(19毫米);为VDA测试的压缩空气供应内径半英寸或更高。储气罐容量:130L的气灌。工作温度:-20 ℃至40 ℃ 。相对湿度zui高值:温度高达31 ℃ 时80 %线性降低到50%相对湿度在40℃时 。...
