TH57404B - Gas leak ventilator And pollution control systems from the crankcase of the internal combustion engine - Google Patents

Abstract

DC60 (11/07/16) in an internal combustion engine. Part of the fresh air is extracted from the intake system. Will be heated And is delivered into the crankcase to increase the temperature of the crankcase atmosphere. To support the atomization of the gas leak to prevent the water in the gas leak from mixing. In as much lubricant as possible Which suppress the degradation of the lubricant Part of the gas leak recovery device Will be limited by the space outside of Catalyst double-walled construction for flue gas purification Or exhaust pipe With double walls This is provided between the internal combustion engine and the muffler, so the leaking gas can be effectively heated with high temperature exhaust gases. Structure can be Normalized And can reduce the price. Conclusion 11/07/2016 in the internal combustion engine Part of the fresh air is extracted from the intake system. Will be heated And is delivered into the crankcase to increase the temperature of the crankcase atmosphere. To help support the atomization of the gas leak to prevent the water in the gas leak from mixing. In as much lubricant as possible Which suppress the degradation of the lubricant Part of the gas leak reverse rotation device Will be limited by the space outside of Catalyst double-walled construction for flue gas purification Or exhaust pipe With double walls This is provided between the internal combustion engine and the muffler, so the leaking gas can be effectively heated with high temperature exhaust gases. Structure can be Normalized And can reduce the price -------------------------------------------------- --------------------
