摘要
我國(guó)在傳統(tǒng)內(nèi)燃機(jī)特別是柴油機(jī)技術(shù)上，落后于世界先進(jìn)水平15～20年。而在新型能源發(fā)動(dòng)機(jī)研發(fā)上則不然。有專家指出，我國(guó)在環(huán)保型發(fā)動(dòng)機(jī)的研制上，與國(guó)際先進(jìn)水平僅有約5年的差距，某些方面可能還略有優(yōu)勢(shì)。發(fā)展新型能源發(fā)動(dòng)機(jī)對(duì)于中國(guó)發(fā)動(dòng)機(jī)制造行業(yè)有一個(gè)現(xiàn)實(shí)好處，即在傳統(tǒng)發(fā)動(dòng)機(jī)制造領(lǐng)域，中國(guó)已經(jīng)失去了追趕的機(jī)會(huì)，而在新型能源發(fā)動(dòng)機(jī)領(lǐng)域，與國(guó)外相比，技術(shù)水平和產(chǎn)業(yè)化程度的差距相對(duì)較小。

Summary
Our country in traditional I.C. engine especially diesel engine technique,15 20 years of ～ss in advanced level in in arrear of world.But in new energy launching machine development not.There is expert pointing out, our country in environmental protection type launching machine researching to manufacture, with international advanced level only contain roughly 5 years' margin, some aspects may still have the advantage slightly.The new energy in development launches the machine lost China launch mechanism build profession have a realistic advantage, in the tradition launch mechanism build realm, China very much the opportunity that chase, but launch the machine realm in the new energy, comparing with foreign country, the technique level turns the margin of the degree with the industry opposite smaller

引言
目前(2002年)我國(guó)的能源消費(fèi)結(jié)構(gòu)中，煤炭占66.1%，石油占23.4%，天然氣占2.7%，水電占7.8%。我國(guó)是一個(gè)石油資源短缺的國(guó)家，卻是亞太地區(qū)最大的石油消費(fèi)國(guó)，面臨的矛盾和問(wèn)題非常突出。
