安全氣囊在不到一秒的時間內彈出,在碰撞過程中為乘客與堅硬的內裝表面之間提供柔軟的屏障。火星塞產生火花以點燃燃燒室中的油氣混合物,從而啟動引擎的動力循環。空氣濾清器會過濾灰塵、花粉、葉子和其他雜物,確保只有乾淨的空氣進入引擎以進行正常燃燒。當您踩下煞車踏板時,煞車片(來令片)會壓向煞車碟盤,產生摩擦力以減速並停止車輛。雨刷可清除擋風玻璃上的雨、雪、泥土和其他碎片,讓駕駛能看清前方道路。排檔桿(或稱變速桿)讓手排車的駕駛員能夠選擇不同的檔位。機油濾清器可去除機油中的污垢、金屬顆粒和其他污染物,使機油能持續潤滑並保護引擎。活塞在汽缸內上下移動。燃燒產生的力量將它們向下推,這種運動被轉化為最終驅動輪胎轉動的旋轉力。散熱器將引擎冷卻液的熱量轉移到外部空氣中,防止引擎過熱。汽車蓄電池(電瓶)提供啟動馬達所需的高電流,並在引擎關閉時為電氣系統供電。避震器(及支柱總成)能緩衝彈簧的上下運動,讓車輛在經過顛簸路面後不會持續彈跳。消音器是排氣系統的一部分,它利用腔室和隔板來降低引擎排出的廢氣所產生的巨大脈衝噪音。輪胎提供與路面的接觸面,用於抓地、煞車及操控,同時也能吸收部分路面震動。飛輪儲存來自引擎動力行程的旋轉能量,並在非動力行程期間釋放,使引擎運行平順,並協助手排車進行換檔。噴油嘴在適當時機將精確數量的燃料噴入引擎的進氣口或燃燒室,以實現高效燃燒。發電機將引擎的機械能轉化為電能,以保持電池電量並運行車燈、收音機和其他配件。觸媒轉化器利用化學催化劑將有害廢氣(如一氧化碳和氮氧化物)轉化為危害較小的物質。起動馬達是一個電動馬達,它嚙合飛輪或驅動盤並旋轉引擎,直到引擎開始自行運轉。正時皮帶或正時鏈條將曲軸與凸輪軸連接起來,使氣門與活塞精確同步運行。曲軸具有通過連桿與活塞相連的偏心軸頸;當活塞上下移動時,曲軸便會旋轉。凸輪軸具有特殊形狀的凸輪,可推動氣門機構組件,在引擎循環的正確時刻開啟氣門。方向盤(透過轉向柱和連桿或電力輔助)連接到前輪,使駕駛員能夠操控車輛。前大燈照亮車輛前方的道路,也讓其他駕駛員更容易看到該車。排氣系統(管道、消音器、觸媒轉化器等)將高溫廢氣安全地引導離開引擎和乘客。變速箱增加引擎扭矩並提供不同的齒輪比,使汽車可以加速、高效巡航和倒車。離合器允許駕駛者暫時將引擎動力與變速箱斷開,以便順暢地換檔。煞車碟盤隨車輪旋轉。當煞車片擠壓它時,摩擦力將汽車的動能轉化為熱能並使車輛減速。燃油箱安全地儲存車輛供應的汽油或柴油,直到其被泵送到引擎。水泵由引擎驅動(通常透過皮帶),保持冷卻液流經引擎缸體、汽缸蓋和散熱器。當引擎寒冷時,節溫器保持關閉以便快速升溫,一旦引擎達到工作溫度,它就會開啟以允許冷卻液流向散熱器。蛇形皮帶繞過多個滑輪,將引擎動力傳遞給維持汽車運行和舒適性的各種配件。該感測器告訴引擎電腦和儀表板溫度計冷卻液有多熱,以便系統調整燃油混合比、風扇運作,並在需要時警告駕駛員。油底殼在引擎底部形成儲油槽,當引擎不運轉時機油會匯集於此,機油泵從中抽取機油。引擎蓋是覆蓋引擎室並提供維修通道的鉸鏈式面板。保險桿旨在吸收低速碰撞能量,並幫助保護更昂貴的車身和機械組件。車內後視鏡和車外側視鏡為駕駛者提供了觀察車後及車側交通情況的必要視野。安全帶在緊急制動或碰撞時將乘客固定在座位上,大大降低了嚴重受傷的風險。油尺是一根帶有刻度的金屬棒,從引擎中拔出後可以查看機油量以及是否需要添加。保險絲是犧牲性裝置,在發生過載或短路時會熔斷並斷開電路,保護線路和元件免受損壞。水箱護罩讓冷卻空氣流向散熱器,同時也有助於車輛的外觀設計,並保護散熱器免受較大碎屑的侵害。You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
