拖拉机的废气涡轮增压装置类似空气压缩机,通过压缩空气滤清器管道送来的空气进行增压来提高发动机的进气量,使柴油机在外形结构尺寸和排量不变的条件下明显提高输出功率、增大了输出扭矩,同时与同等功率的柴油机相比降低了油耗,减少了排气污染。在发动机正常工作过程中,长期处在排气管内的高温下高速运转(废气涡轮增压器的转速高达十几万r/min),工作条件十分恶劣,使拖拉机在使用过程中,都不同程度地出现过由于增压器使用不当而造成的动力下降、油耗上升, Tractor exhaust gas turbocharger is similar to the air compressor, compressed air filter pipe through the air sent to supercharge to improve the engine intake, so that the diesel engine in the shape and size of the structure under the same displacement unchanged Output power, increased output torque, while reducing fuel consumption compared with the same power diesel engine, reducing exhaust pollution. In the normal course of the engine, long-term in the exhaust pipe at high speed high-speed operation (exhaust gas turbocharger speed up to tens of thousands of r / min), the working conditions are very poor, the tractor in use, are varying degrees Appeared to have been due to improper use of turbocharger caused by decreased power consumption, fuel consumption,
