动力机械：内燃机配气机构控制内燃机进气和排气的机构。内燃机在完成一个工作循环以后﹐为了持续地工作必须将膨胀作功后的废气排出气缸﹐并及时地吸入新鲜充量(空气或可燃混合气)。配气机构按内燃机各缸工作顺序﹐适时地开启和关闭进﹑排气门或进﹑排气口(见二冲程内燃机)﹐以保证充分换气。 布置形式 配气机构按气门在内燃机上布置的方式可分为侧置气门式和顶置气门式两类(图1 配气机构的布置形式 )。侧置气门式﹕结构简单﹐但进﹑排气阻力大﹐燃烧室难以设计得紧凑﹐抗爆震性和高速性都差﹐燃料消耗率又高﹐故现代内燃机很少采用﹐只在强化程度低的汽油机上还有采用的。顶置气门式﹕由于燃烧室紧凑﹐进﹑排气阻力小﹐可以增多内燃机的新鲜充量和提高汽油机的压缩比﹐内燃机的动力性能和经济性能都优于侧置气门式﹐在柴油机和汽油机中得到广泛应用。顶置气门式配气机构又可分为下置凸轮轴和顶置凸轮轴两种。后者的凸轮轴置于气缸盖上﹐凸轮直接或通过摇臂开启气门﹐由于没有挺柱和推杆﹐惯性力﹑振动和变形都较小﹐改善了内燃机的高速性能﹐在高转速﹑高性能的内燃机上获得更多的应用。 主要构件及其作用 配气机构通常由气门组﹑摇臂﹑挺柱﹑推杆﹑凸轮轴及其传动机构组成。图2 下置凸轮轴的顶置气门式配气机构 为下置凸轮轴的顶置气门式配气机构﹐这种型式应用最广。它由气门组﹑摇臂﹑推杆﹑挺柱和凸轮轴组成。 气门组﹕由气门﹑气门座﹑气门弹簧﹑气门弹簧座﹑锁片和气门导管组成。气门头部的锥面与气门座的内锥面紧密贴合﹐以保证密封。气门头部与气缸内的燃气直接接触。高温的燃气排出时流经排气门﹐可使排气门温度高达600～900℃。进气门温度约为300～400℃。因此要求气门材料耐热﹑耐磨和耐腐蚀。通常排气门采用耐热合金钢﹐进气门采用普通合金钢。气门座可以在气缸盖上或机体上直接镗出﹐但考虑到它在高温下工作﹐磨损严重﹐所以通常用耐热合金钢或合金铸铁制成单独的环形气门座圈﹐压入气缸盖或机体﹐以便于磨损后更换气门座。气门导管的作用是引导气门上下移动﹐并使气门头部锥面与气门座紧密贴合。气门导管通常用铸铁或粉末冶金制成﹐压入气缸盖或机体。气门弹簧用来保证气门关闭时能使气门头部锥面与气门座贴紧。
