CLAIMS SUMMARY DESCRIPTION (EN RU) DRAWINGS (EN RU)
1.The device for vapors condensation reducing in the crankcase of an internal combustion engine, comprising the cooler-trap for cooling crankcase gases passing through it, condensation of the said vapors from them and collection of their condensate, representing the flowing for crankcase gases reservoir cooled by ambient air, connected to the top of crankcase by the inlet channel for input of heated crankcase gases and the outlet channel for output cooled and dried gases into the crankcase.
2. The device of claim 1, wherein the said inlet channel for input of heated crankcase gases into the cooler-trap is additionally equipped with an oil catcher.
3. The device according to claim 1, characterized in that the said inlet of the channel for input of heated crankcase gases into the cooler-trap is on the top of the last at the maximum possible by performance capabilities height from the crankcase top, and the outlet of channel for output of cooled and dried gases into the crankcase - from the bottom of cooler-trap, for formation sufficient stack effect of crankcase gases in the thermocirculation circuit formed with the hot (the channel for input of heated crankcase gases into the cooler-trap) and cold (the cooler-trap and the channel for output of cooled and dried gases into the crankcase) bends.
4. The device of claim 1, wherein the said channel for input of heated crankcase gases into the cooler-trap is made as or heat-insulated, or heated, or heat-insulated and heated.
5. The device of claim 4, wherein in a special case the said channel for input of heated crankcase gases into the cooler-trap is performed within the cylinder block from the top of crankcase up to the top of cylinder block, where it is connected to the top of cooler-trap.
6. The device according to claim 1, characterized in that it additionally involves the channel ventilator, placed in the cooler-trap outlet channel for output of cooled and dried gases into the crankcase, producing during engine warming-up the cooled and dried flow of crankcase gases from the cooler-trap into the crankcase, put in action by a board power-supply source and switched off when the crankcase temperature runs up to the set value.
7. The device of claim 6, wherein the said channel ventilator supports the ratio of crankcase gases circulation through the cooler-trap, equal to the ratio of crankcase gases flow through the cooler-trap to the crankcase gases flux from 1 to 32.
8. The device of claim 1, wherein the said cooler-trap is made in a form of the vessel with developed surface from a high heat-conducting thin-walled material and has in its bottom part the volume enough for vapors condensate imbedding.
9. The device of claim 8, wherein the enough volume for vapors condensate imbedding is achieved by arranging the top end of outlet channel for output of cooled and dried gases into the crankcase from the cooler-trap within the last, on the distance from its bottom enough for forming of the mentioned volume in the aggregate with cross-section area of the cooler-trap.
10. The device according to claim 8, characterized in that the said cooler-trap is made in a form of the thin-walled silphon, with or circular, or rectangular cross-section.
.
11. The device of claim 10, wherein the said thin-walled silphon is armored with wire rings put in the V-type ditches between the flutes.
12.The device of claim 8, wherein the cooler-trap is equipped with a flow distributor of entering heated crankcase gases, directing the flow down vessel walls.
13. The device of claim 1, characterized in that in a special case it additionally includes the condensate evaporator made in a form of the flowing for crankcase gases reservoir built into the channel for input of crankcase gases from the crankcase into the engine inlet manifold between the oil catcher and the crankcase ventilation valve, connected to the bottom of cooler-trap with a pipe for condensate drain from the cooler-trap into the evaporator, where the condensate is evaporated during the engine run by heat of crankcase gases and with the last enters the engine inlet manifold.
14. The device of claim 13, wherein the said condensate evaporator is made in a form of the vessel with outside heat insulation.
.
15.The device of claim 13, wherein the inlet of channel for the crankcase gases input from the crankcase into the engine inlet manifold into the said condensate evaporator is made in a form of a heat-conducting pipe, whose end is arranged within the condensate evaporator on a distance from its bottom enough in aggregate with cross-section area of the evaporator for the condensate imbedding.
16.The device of claim 15, wherein a baffler is arranged over the heat-conducting pipe end for turning of the inlet flow of crankcase gases entering the evaporator to the surface of condensate, placed in the condensate evaporator.
17. The device according to claim 1, characterized in that in a special case it additionally involves the condensate buffer unit, that is the reservoir with enough volume for condensate embedding, connected to the bottom of the cooler-trap with a pipe for the condensate draining from the cooler-trap into the condensate buffer unit, attached at the crankcase top with a heat-conducting join, heat-insulated from above and connected to the crankcase through the valve, which is opened by a sensor of crankcase temperature, when it runs up to the set value, after which the collected and melted condensate enters the warmed-up crankcase, where it is evaporated and enters the engine inlet manifold as crankcase gases constituent.
