All automobile engines now built are equipped with the positive-crankcase ventilation system of crankcase emission control.
所有现代制造的汽车发动机，都需要装备控制曲轴箱有害污染的曲轴箱强制通风系统。
Positive crankcase ventilation (PCV)
积极式曲轴箱通风系统
The crankcase ventilation system carries fresh air through the crankcase.
曲轴箱通风系统要携带新鲜的空气通过曲轴箱。
The crankcaseventilation system, using a road-draft tube, vented the crankcase vapors and blow-by gas into the atmosphere.
采用行车抽吸管的曲轴箱通风系统，给曲轴箱内的蒸气和窜漏气体排入大气提供了出口。
The positive crankcase ventilation valve and gas caps with air-pollution control valves reduce volatile organic compound loss.
曲柄轴箱通风阀和配有废气帽的空气污染控制阀（使用）减少挥发性有机混合物释放有积极作用。
