462缸徑的(de)(de)大(da)小為(wei)62mm和(he)465缸徑的(de)(de)大(da)小為(wei)65mm，462的(de)(de)發(fa)動機功率一般在28千瓦(wa)左(zuo)(zuo)右，465的(de)(de)發(fa)動機功率一般在38千瓦(wa)左(zuo)(zuo)右。

發(fa)(fa)動(dong)機的性(xing)能指(zhi)(zhi)(zhi)標(biao)(biao)用來表(biao)征發(fa)(fa)動(dong)機的性(xing)能特點，并作為評價(jia)各類發(fa)(fa)動(dong)機性(xing)能優劣的依據。發(fa)(fa)動(dong)機的性(xing)能指(zhi)(zhi)(zhi)標(biao)(biao)主要(yao)有：動(dong)力性(xing)指(zhi)(zhi)(zhi)標(biao)(biao)、經濟(ji)性(xing)指(zhi)(zhi)(zhi)標(biao)(biao)、環(huan)境(jing)指(zhi)(zhi)(zhi)標(biao)(biao)、可靠性(xing)指(zhi)(zhi)(zhi)標(biao)(biao)和耐(nai)久性(xing)指(zhi)(zhi)(zhi)標(biao)(biao)。

汽(qi)(qi)車(che)(che)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)是為汽(qi)(qi)車(che)(che)提供動(dong)(dong)(dong)(dong)力的發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)，是汽(qi)(qi)車(che)(che)的心臟，影響汽(qi)(qi)車(che)(che)的動(dong)(dong)(dong)(dong)力性、經濟性和(he)環保性。根(gen)據動(dong)(dong)(dong)(dong)力來源不同，汽(qi)(qi)車(che)(che)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)可分為柴油發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)、汽(qi)(qi)油發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)、電動(dong)(dong)(dong)(dong)汽(qi)(qi)車(che)(che)電動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)以及混合動(dong)(dong)(dong)(dong)力等。
