强制发动机与积极的性质-在5- 50%内提升具有相当大的缺点，即其服务可靠性的降低。对文献进行的分析表明，涡轮压缩机故障的数量有相当大的增加。其主要原因是：运行人员不遵守启停方式;违反检修标准;负荷方式随机性大（10- 150%）。涡轮压缩机及其元件的可操作性和无故障性能的增加可以通过应用所建议的涡轮压缩机内燃机的润滑系统来实现。涡轮压缩机内燃发动机的润滑系统与涡轮压缩机转子制动的自主润滑制动装置和自主控制系统的使用防止了在涡轮压缩机润滑系统的通道中的润滑油残余物在突然故障的情况下焦化。- 在涡轮压缩机转子降速模式下的内燃机的（紧急加载）关闭，这意味着一个受管制的供应（通过体积、时间和温度）的涡轮压缩机轴承中的油，以及调节的（通过温度）将由涡轮压缩机泵轮压缩的空气供应到涡轮压缩机涡轮机轮的入口，降低了涡轮机部件的温度，温度为600- 700 o С，总体上提高了轴承、转子、机体和涡轮压缩机的使用可靠性。自动润滑制动装置在汽车、拖拉机和车辆用联合收割机柴油机上的工程实例应用，可使涡轮压缩机故障减少10- 15%。估计的经济效益包括增加单位容量的移动的能量转换机械的每个操作季节50- 80 K卢布。
Forcing of engines together with positive properties – uprating within 5–50 % has a considerable drawback, i.e. the decrease of its service reliability. The performed analysis of literature points at a considerable increase in the number of turbocompressor failures. The main causes are as follows: nonobservance of the startup and shutdown modes by the operators; breach of the maintenance standards; high randomness of the load modes of 10-150%. The operability and increase of the failure-free performance of the turbocompressor and its elements can be achieved by the application of the suggested lubrication system of the turbocompressor internal combustion engines. The use of the lubrication system of the turbocompressor internal combustion engines with an autonomous lubrication-brake device and an autonomous control system of the turbocompressor rotor braking prevents coking of lubricant oil residues in channels of the turbocompressor lubrication system in case of a sudden (emergency loaded) shutdown of the internal combustion engine in the mode of the turbocompressor rotor rundown, and implies a regulated supply (by the volume, time and temperature) of oil in the turbocompressor bearing, as well as a regulated (by temperature) supply of the air compressed by the turbocompressor pump wheel to the inlet of the turbocompressor turbine wheel, which reduces the temperature of the turbine parts with the temperature of 600–700oС, wherein the service reliability of the bearings, rotor, body and the turbocompressor in general is increased. The application of engineering samples of the autonomous lubrication-brake device on car-and tractor and combine machine diesel engines of vehicles allows decreasing the number of turbocompressor failures by 10–15 %. The estimated economic effect comprises 50–80K rubles per season of operation of mobile energy-converting machinery with the increased unit capacity.
