就节能和环保来看,我国卡车进气系统的发展趋势是应用涡轮增压技术且发动机曲轴通风箱废气闭式排放,从而提高燃油效率和减少废气排放。针对不同的进气系统,其管路应有与之匹配的性能和要求。目前我国卡车的进气系统可大体按有无涡轮增压器分为2类,其中部分轻卡和中重卡的进气系统无涡轮增压器,大多数中重卡目前已采用涡轮增压器,其技术日渐成熟,但其发动机曲轴通风箱致
In terms of energy conservation and environmental protection, the development trend of the truck air intake system in our country is the application of turbocharger technology and the closed-end exhaust of the crankcase ventilation box of the engine, thereby improving fuel efficiency and reducing exhaust emissions. For different intake systems, the piping should have matching performance and requirements. At present, the intake system of China’s trucks can generally be divided into two categories with or without turbochargers, some of which have no turbocharger in the intake system of the light truck and the medium-heavy truck, and most of the medium-heavy trucks currently use a turbocharger. Technology is maturing, but the engine crankshaft ventilation box caused
