Abstract

本实用新型是对现有内燃机缸套的一种改进,即在内燃机缸套外表面上相对于活塞运行的部位车一圈浅槽,槽内包复耐高温的云母板,形成隔热圈,使内燃机燃烧室内的热能不易散失,以维持较高的温度,使燃油能完成燃烧,而提高效率、降低油耗。

Description

一种内燃机缸套
本实用新型涉及内燃机配件,特别是一种内燃机缸套。
为了延长内燃机的使用寿命,便于维修和更换,现有内燃机的缸体上都镶有缸套,活塞在缸套和缸盖形成的燃烧室里运行。由于缸套是铸铁或合金铝等制成的金属件,其热传导及热辐射能力较强,致使燃烧室内的温度不能维持相对较高的水平。这样燃油在燃烧室内就不能完全燃烧,能量转换率偏低,使内燃机功率下降,还易产生积炭,影响使用。
本实用新型的目的是提供一种能促使燃油充分燃烧,从而提高内燃机功率,降低油耗的内燃机缸套。
为完成发明目的而设计的内燃机缸套,其结构形状与现有内燃机缸套基本一致,其特点是缸套的外表层上相对于活塞运行部位有一圈深度为1-3毫米的浅槽,浅槽内包有耐高温的云母隔热板层。这样就能大大阻隔燃烧室内的热能散发,使燃烧室在工作时维持一个相对较高的温度,以保证进入燃烧室内的燃油能完全燃烧,使其能量充分释放和转换。这样不会再有积炭产生,内燃机的功率亦能明显提高,油耗自然就下降了。
为了使缸套浅槽内的云母板层不易损坏脱落,可在云母隔热板层外镶包上与缸套外表面平齐的金属防护层。
以下结合附图实施例详细描述本实用新型。
图1为本实用新型单缸或多缸柴油机铸铁缸套示意图。
如图1所示,铸铁缸套1的外表面上阻水圈3以下,相对于活塞运行部位有一圈深约2.5毫米的浅槽5,浅槽5内包有一层厚度约为0.5毫米的云母板层4,其外包有钢板防护层2,且与缸套1外表面平齐。
以s195单缸柴油机为例,活塞行程115毫米,浅槽5及云母板层的宽度一般为70至80毫米即可。使用这种缸套的s195柴油机,其功率可提高0.5马力,而油耗每小时能降低46克左右。
