Abstract

The problem of increasing the unit power of the engine without making changes to its design is solve by using a turbo supercharger. However, due to the intensity of the turbochargers operating mode, which are characterized by engine speed variability due to changing load indicators during operation (the number of rotor revolutions varies from 30000 min-1 to 120000 min-1, engine exhaust gases have a temperature of about 7500C), there is a need to improve the efficiency of the turbocharger bearing lubrication system. The purpose of the research is to ensure the operability and increase the reliability of turbochargers of diesel engines. To achieve this goal, a constructive solution for the lubrication system of the bearing assembly was propose, i.e., a membrane-type hydraulic accumulator was structurally provided in the lubrication system of the bearing assembly. Experimental studies were conduct to identify the operability and effectiveness of this constructive solution. The experiment was carried out on the KAMAZ-740 engine, the turbocharger shaft drive was carried out in normal mode, that is, from exhaust gases. L-02-40 fuel was use, SAE 10W–40 API was use as a lubricant. The turbocharger shaft speed varied from minimum to maximum by changing the engine speed and then stopping it. During the experiments, the following parameters of the turbocharger operation were measure: the duration of inertial rotation of the turbocharger rotor; the duration of pressure reduction in the turbocharger lubrication system. The dependences of the influence of the duration of the pressure drop in the turbocharger lubrication system and the duration of rotation of the turbocharger shaft by inertia with parallel inclusion of the accumulator in its lubrication system and in the normal mode of lubrication of the bearing are reveal. It is established that the installation of a device for feeding the turbocharger bearing during a sharp reduction in engine speed will increase the run-out of the turbocharger rotor from 30 to 65 s while maintaining the normal operating mode of the turbocharger lubrication system
