随着增压技术的发展,装有增压柴油机的机械车辆越来越多。因此,掌握增压柴油机的特点,正确使用增压柴油机,及时发现、排除其故障,对于延长机械车辆寿命,提高机械车辆的完好率具有重意义。1 增压柴油机的特点目前,提高柴油机功率最有效的措施是增加充气量和供油量,国内外通常采用废气涡轮增压器来达到这一目的。废气涡轮增压器是利用柴油机排出的废气脉冲能量驱动径流式涡轮,带动与涡轮同轴的的离心式压气机叶轮高速旋转,来使进气压力升高,提高柴油机的充气量的。
With the development of booster technology, there are more and more mechanical vehicles equipped with turbocharged diesel engines. Therefore, grasping the characteristics of turbocharged diesel engine, correctly using turbocharged diesel engine, discovering and eliminating its fault in time is of great significance to prolong the life of the mechanical vehicle and improve the integrity of the mechanical vehicle. 1 characteristics of turbocharged diesel engine At present, the most effective measures to increase diesel engine power is to increase the amount of inflatable and fuel supply, exhaust turbochargers are usually used at home and abroad to achieve this goal. Exhaust gas turbocharger is the use of diesel exhaust gas pulse energy driven radial turbine, driven coaxial with the turbine centrifugal compressor impeller high-speed rotation, to make the intake pressure, increase the amount of diesel engine inflation.
