Abstract：In order to ensure that the crankcase ventilation system can meet the regulatory requirements， through the interpretation of emission regulations and combined with the working principle of crankcase ventilation system， the corresponding technical route is selected for each crankcase ventilation pipeline. After balancing the conflicting vehicle objectives and costs， the optimal design scheme of each crankcase ventilation pipeline is determined， which also lays a solid foundation for the subsequent detailed design.
