Abstract:
1. A blow-by treatment assembly for a vehicle having an engine emitting blow-by gas, the blow-by treatment assembly comprising: an exhaust manifold of the engine for receiving exhaust gas; an oil mist separator in downstream fluid communication with the engine for receiving blow-by gas; a breather coking device disposed in downstream fluid communication with the oil mist separator to receive blow-by gas, wherein at least a portion of the breather coking device receives heat transferred from the exhaust manifold to reach a coking temperature where entrained oil is coked out of the blow-by gas and deposited on the breather coking device; a coking outlet of the breather coking device in upstream fluid communication with at least one of a turbocharger compressor and the engine; an exhaust tube in fluid communication with the engine for receiving exhaust gases; and a second portion of the breather coking device receives heat transferred from the exhaust tube to reach a coking temperature where entrained oil is coked out of the blow-by gas and deposited in the breather coking device.
