汽车排放控制技术及润滑油对其影响浅析
【摘 要】随着我国经济的迅猛发展,汽车保有量在全国范围内急剧上升,人们的交通越来越便利,但同时,汽车排放污染也越来越威胁人们赖以生存的环境。因此,积极研究汽车排放控制技术,研制环保型,低排放汽车,已是刻不容缓的课题。现今,控制汽车排放的技术为机内净化和排放后处理净化两类。随着先进排放后处理技术的应用,燃油及润滑油对排放的影响也越来越凸显,排放控制对油品的质量要求也越来越高。润滑油油品如何适应先进排放后处理技术是一个正在研究的课题。

【Abstract】With the rapid development of our country’s economy, a sharp rise in car ownership in the national scope, people more and more convenient transportation, but at the same time, vehicle emission pollution is becoming more and more people rely on environment. Therefore, positive research vehicle emission control technology, the development of environmental protection, low emission vehicles, is urgent topic. Today, the vehicle emission control technology for internal purification and pollution purification. With the application of advanced emission aftertreatment technology, fuel and lubricating oil on emissions also more and more highlights, the influence of emission control has higher requirement about the quality of the product. Lubricating oil how to adapt to the advanced emission aftertreatment technology is a research topic.

0.引言
汽车尾气造成的污染已显而易见并越发严重,汽车排放的污染物正使蓝天变少,雾霾增多,并已对人们的健康构成威胁。所幸,人们已开始意识到污染的严重性。为了有效控制汽车尾气所带来的污染,各国都对汽车排放污染制定了相关的限制性法规,并且要求越来越严格。我国对汽车排放控制的法规也在不断加强与完善,如今,国Ⅴ标准已逐渐普及。汽车厂商为了更好发展,也在大力研发控制汽车排放污染的技术并已有成效。为了使汽车排放控制技术成效显著,一定要考虑其影响因素,并把这些不利因素降低。本文主要从润滑油方面来阐述其对汽车排放控制技术的影响。
