Turbokompressor is brought in rotation from exhaust gases and is intended for air forcing in cylinders of the engine and capacity increase. Pressure of pressurization is limited to a separate zaslonka (the control valve of pressure), a part of exhaust gases providing removal from the turbine.
For cooling of forced air (approximately on 30 ° C) and increases of its density on an entrance in the cylinder the intermediate refrigerator ("interkuler") established on an entrance in an inlet collector is applied.
Greasing of a turbokompressor which rotates with a speed 140000 about / mines, is provided with oil for the engine. To greasing of this unit increased requirements (regular change of oil and the filter, the increased purity of oil) are shown.
Basic rules of operation
After start-up of the cold engine warm up it on small turns (in cold weather of 1-2 mines) that viscosity of oil went down to the set level and compressor greasing improved.
Before an engine stop after driving under trying conditions it should work idling to warn a zakoksovyvaniye of oil channels of the compressor.
If the heated-up engine decayed, immediately restart it to prevent strong heating and a compressor exit out of operation.
It is forbidden to assort a turbokompressor independently
Removal and installation
Removal and installation of a turbokompressor is carried out according to items of 1-9 procedures of removal of collectors of a diesel engine (see subsection 3.4.17). |
