使用废气涡轮增压器可以在柴油机结构不变的情况下提高功率、降低燃油消耗率、缩小柴油机的外形尺寸,是现代柴油机提高动力性和经济性的重要手段。涡轮增压器是利用柴油机排出的废气能量驱动涡轮高速旋转,带动与涡轮同轴的压气机叶轮高速旋转,从而使空气压缩后才进柴油机气缸,增加了柴油机的进气量,可供更多的燃油完全燃烧,进一步提高柴油机的功率。同时,因燃烧条件的改善,还可减少废气中有害物质的排放,降低噪声。涡轮增压器工作过程中经常出现漏油现象。漏油原因及预防措施介绍如 The exhaust turbocharger can increase the power, reduce the fuel consumption rate and reduce the size of the diesel engine under the condition of unchanged diesel engine structure, which is an important means of improving the power and economy of a modern diesel engine. Turbocharger is the use of exhaust emissions from diesel engine driven high-speed turbine rotation, driven coaxial with the turbine impeller high-speed rotation, so that compressed air into the diesel engine cylinder, increasing the amount of diesel engine intake for more Complete combustion of the fuel, to further improve the power of diesel engines. At the same time, due to improved combustion conditions, but also reduce exhaust emissions of harmful substances and reduce noise. Turbocharger often leak oil during work. Leakage reasons and preventive measures such as introduction
