No matter what engine is adopted, a carbureted engine or an EFI engine, for meeting EURO ⅲ, the catalytic control is the best effective technically. 无论是采用化油器还是电喷发动机,要满足欧Ⅲ排放标准,催化净化是最有效的技术手段。
The Technical Research on the Preparation of Vacuum Carbureted Medium ── the Mixture of Methane and Hydrogen by Cracking of Liquidized Hydrocarbon 液化烃热裂解法制取真空渗碳介质&甲烷、氢混合气的工艺研究
This paper deals with the preparation process of vacuum carbureted medium-the mixture of methane and hydrogen by cracking oil tail-liquidized hydrocarbon at normal pressure. 本文研究了在常压下由石油尾气液化烃热裂解法制取真空渗碳介质&甲烷、氢混合气的工艺。
By undirect way, using naphtha, LPG or natural gas as raw material makes reformed gas carbureted with natural gas to get the product gas, which is completely suitable to the existing networks and utensils. 以非直供方式,用石脑油、LPG或天然气做原料生产出改质气,再用天然气增热,得到与现有管网、用户燃气具完全适应的产品气。
