Description
44^796 五、發明說明(1) 本發明係有關一種内燃機之汽缸頭,包括至少一設在殼 體内的汽缸頭底座,其設有至少一氣體交換通道開孔,且 汽飯頭底座與殼體由不同材料構成。 專利EP 〇 120 223 A2提出一種汽缸頭,其包括一壓入 ϊ飞缸頊外殼的圓板狀汽缸頭底座。該以燒結製造的板作用 在於隔熱。鋼製汽門座設在此基本上由矽酸鋁構成的板 中 〇 〇 專利US 4 774 91 2提出一種内燃機之組合汽缸頭,包括 一兩件式汽缸頭,其具有一與汽缸頭殼體連接的汽缸頭底 座。該汽缸頭底座材料強度高於汽缸頭殼體材料。 習知具分離之汽缸頭底座的汽缸頭缺點在於,有時汽缸 頭底座與汽缸頭殼體之連接可能鬆脫。 本發明之目的因此在於,避免上述缺點,進—步改良此 種汽缸頊底座’使得汽缸頭底座與汽缸頭殼體之連接可靠 且不會鬆脫。 1 本發明如下達成上述目的:汽缸頭底座至少設有一形狀 。齒合部’並鑄入殼體中。如此在汽缸頭底座與汽缸頭殼體 產生一形狀嚙合連接,使得即使長時間使用後連接仍不合 鬆脫。 曰 形狀喷合部在汽缸頭底座邊緣至少設有一凸起及/或一 凹陷時,尤其可達到可靠的連接。在製造上特別簡單的 疋’使形狀响合件環狀繞行。 於是在;紅頭底座周壁設一形狀嗜合部。其他形狀喷合 部可設在朝向燃燒室的頂面邊緣處,以及氣體交換通道接 446796
通汽缸頭底座處。環繞氣體交換通道的形狀嚙合部作用亦 在於防止漏油。 在一特別優先之實施例中,汽缸頭底座由一單一材料製 成,耽肢父換a門的汽門座設在汽缸頭底座中。故可捨棄 分離的汽門座環。使得汽缸頭底座氣體交換通道開孔間的 距離小於使用汽門座環時甚多,故氣體交換通道之開口截 面可較大。增加的截面可達,甚至更多。 在本發明的進一步實施中,可使汽缸頭底座至少設一開 孔’以容置一接通至燃燒室之内置件,尤其是一火星塞及
/或/一喷射汽門,固定該内置件的套筒與汽缸頭底座一體 成形。内置件,例如火星塞及/或噴射汽門,因此可直接 固定在汽缸頭底座上。 別簡單的製造為,使至少一支撐氣體交換汽門的汽門 導S與 >飞缸碩底座一體成形。汽門導管因此可與汽缸頭底 座一起禱入殼體中,而不需使用其他定位方法。為使汽缸 f底座與汽缸頭殼體達到一可靠連接,故使汽門導管外側 «又有一形狀嚙合體,最好是至少一環繞之凸起。汽門導管 與汽缸頭底座可有利地以橋片連接。
j另一極有利的實施例中’ 一汽缸襯筒與汽缸頭底座一 去、形。在 >飞缸襯筒外侧至少設一形嚙合部,而與殼體 達到可靠連接。 π缸頭底座最好由鑄鐵,例如具疊層石墨、球形石墨或 L紋石墨之灰口鑄鐵,或鑄鋼製成。殼體可由輕金屬製 成,例如鋁。
