汽油發(fa)電(dian)機通常由定(ding)子(zi)、轉子(zi)、端蓋(gai)及軸承等部件構成(cheng)，有省油、低噪音、可靠等優點。其有著穩定(ding)的(de)自(zi)動電(dian)壓(ya)調(diao)節系(xi)統(tong)和機油警告(gao)系(xi)統(tong)，在設(she)備(bei)加載時能(neng)自(zi)動保持電(dian)壓(ya)的(de)穩定(ding)，確保提供平穩的(de)電(dian)力，而當機油油位過低時，機油警(jing)告(gao)系統(tong)自動(dong)停止發動(dong)機運轉,使(shi)發(fa)(fa)動(dong)機免受損壞。汽(qi)油(you)發(fa)(fa)電(dian)(dian)(dian)機比柴(chai)油(you)發(fa)(fa)電(dian)(dian)(dian)機更輕便，所以汽(qi)油(you)發(fa)(fa)電(dian)(dian)(dian)機通常(chang)是用于(yu)應(ying)急通訊、搶修或者是小型接入網機房、機房的后(hou)備電(dian)(dian)(dian)源，而現在很(hen)多家庭(ting)也(ye)會購置汽(qi)油(you)發(fa)(fa)電(dian)(dian)(dian)機作后(hou)備電(dian)(dian)(dian)源。汽(qi)油(you)發(fa)(fa)電(dian)(dian)(dian)機的主要功率是650W~20KW不(bu)等(deng)，在選(xuan)購時可根據自身需求(qiu)及發電機用(yong)途來選(xuan)擇，普(pu)通(tong)家庭購置(zhi)功率2KW左右的即可。
