及姿勢無關充滿著潤滑油，如上所述，藉由將溫度檢測器 7 3的檢測元件部7 3 a配置爲面向著該潤滑油供給通路6 7， 即可極爲不易受到引E擎的運轉狀態及姿勢的變化的影 響’可經常良好且迅速地檢測出引擎溫度，而且，就溫度 檢測器7 3來說不需要檢測潤滑油溫度的其他複雜的構造。 而且，因爲將潤滑油供給通路6 7配置於汽缸頭3 7中較 排氣口 48更爲接近吸氣口 47的附近位置，因此，極爲不 易受到來自引擎本體34的外表面部的因環境引起的散熱 的影響，即使在引擎E起動後的低旋轉（空轉狀態）時，仍 可良好地檢測出引擎溫度，可經常良好且迅速地檢測出引 擎溫度。 因爲引擎E係爲以在上述汽缸塊36及汽缸頭37上設置 著空冷用之冷卻鰭片36a…、3 7a…的方式構成爲強制空冷 式者，且，溫度檢測器7 3係安裝於未設置空冷風扇的頭蓋 38上，因此，即不會受到冷卻鰭片36a…、3 7a…的干擾而 可正確檢測引擎溫度，而且’安裝溫度檢測器7 3用的構造 也變得簡單。 此外，在連接上述吸氣口 4 7的氣化器1 〇 8上，安裝著 用以開閉設於該氣化器1〇8的起動用混合氣通路113的基 於溫度檢測器7 3的檢測値進行通電控制的機車起動器 23 312/發明說明書(補件)/92-06/92107258 200400140 1 1 1 ’因此，基於由溫度檢測器7 3正確檢測出的引擎溫度， 將起動時供給引擎E的混合氣最合適化，從而可提升引擎 E的暖機性能。 此外，汽缸塊3 6及汽缸頭3 7，係由使強制空冷用的空 氣流通的流通路8 1形成於汽缸塊3 6及汽缸頭3 7之間的圍 板82所覆蓋，藉由以不受強制性送風的冷卻風的影響的方 式而於頭蓋3 8安裝著溫度檢測器7 3，即使爲強制空冷引 擎之同時，還可正確檢測引擎溫度。 雖於汽缸頭3 7之上部側面，設有使吸氣口 47開口的平

24 312/發明說明書(補件)/92-06/92107258 200400140 又，由於將絕緣體的厚度T係設定爲較安裝面9 7及圍 板8 2間的間隔S大，因此，以壓抵於安裝面9 7的方式將 絕緣體99嵌合於開口部105,即可於組裝時防止絕緣體99 從圍板8 2脫落，可進一步提升組裝性。 另外，連接於汽缸頭3 7的右側面所安裝的火星塞5 1的 栓塞帽121及點火感應圈126，係介由高壓電纜線123所 連接，但是，點火感應圈126係以位於較汽缸頭37後方的 方式而被支持於右側的後架管3 0，一端連接於該點火感應 圈126的上述高壓電纜線123的另一端，係從較栓塞帽121 的前方向著後方呈略U字狀折返而連接於該栓塞帽1 2 1。 據此，連接於該栓塞帽1 2 1之高壓電纜線1 23，成爲從 該栓塞帽121向著前方延伸，即使栓塞帽121與車體框架 2 5中配置於栓塞帽1 2 1的外側的框架構件、亦即與右側的 後架管30之間的間隔變窄，仍可避免與車體框架25的干 涉，而可增大配置高壓電纜線1 2 3的自由度，同時，較大 地設定高壓電纜線123的彎曲半徑，可提升高壓電纜線123 的耐久性。 圍板82係爲具備以協動且覆蓋汽缸塊36及汽缸頭37 的方式，而相互結合的上下一對的上部及下部罩體構件 83、84者，嵌合連接於汽缸頭37的右側面安裝的火星塞 5 1的栓塞帽1 2 1用的嵌合孔1 20，係形成於兩罩體構件 8 3、8 4的配合面8 6間。而且，上部罩體構件8 3上一體設 置著從上面覆蓋嵌入嵌合孔120的栓塞帽121的嵌合部的 庇護部1 2 2，利用來自高壓電纜線1 2 3作用的彈性力而對 25 312/發明說明書(補件)/92-06/92107258 200400140 於火星塞5

可有效防止該高壓電纜線1 23與其他零件的接觸。 而且，藉由庇護部122從上面覆蓋著栓塞帽121的嵌入 嵌合孔120的嵌合部，因此，可防止碰觸比引擎本體34 較爲上面的構件、例如收納箱1 60而掉落的泥水等附著於 高壓電纜線1 2 3及栓塞帽1 2 1的連接部。 此外，保持高壓電纜線123的夾具124，係安裝於連續 上述庇護部122而形成於上部罩體構件83的夾具安裝座 125上，因此，以在栓塞帽121附近保持著高壓電纜線123 的方式，即可更爲有效地防止高壓電纜線1 23的振動，此 外，藉由夾具安裝座125可增加庇護部122的強度。 此外，圍板82的上部罩體構件83上一體設有，前端部 具有相互面對著且向著相互接近側突出的繫合突部 1 2 8 a、1 2 8 a，同時，從上部罩體構件8 3的外面豎起的一對 鉤1 2 8、1 2 8 ;及連結於上述兩鉤1 2 8、1
