节能环保整车毕业论文设计.doc

摘　要 目前我国汽车保有量已达到5000万量，汽车在我国能源消耗和大气排放中均占较大比例。其年消耗量已接近成品油总量的百分之六十。汽车尾气已成为我国城市大气污染中数量最大。累积性最强的毒气。汽车尾气中的CO,CO2，HC,NO2等在直接危害人身体健康的同时也骐达的破坏了人类的生存环境。按照近年来的汽车增长速度和油耗水平有专家预测到到2020年，我国汽车保有量将突破1.5亿大关，年耗油量将突破2.5亿吨，大气污染量也将更重。能源和环境将受到更大挑战，我国政府为应付全球气候变化曾作出庄重承诺，到2020年中国单位国内生产总值一氧化碳排放比2005年下降40%-到50%，这无疑对生产、销售及售后环节，都会产生大量碳排放的汽车生产也提出更高的要求，汽车企业将受到更多的关注，肩负着重大的使命。 汽车产业的节能环保，符合我国能源供给和大众消费水平，有利于缓解紧张状况，保护环境，对于落实国家能源发展战略，加快建设资源节约型、具有重要意义。七尺产业的节能环保既要有汽车企业的自身努力，又要有政府的的支持，更需要全民环保意识不断提高。 关键词：关键词：节能 环保 安全 ABSTRACT At present our country has reached 50 million auto possession, automobile in China amount of energy consumption and atmospheric emissions are accounted for a significant share. Their annual consumption has come close to 60 percent of the product. Automobile exhaust has become Chinas largest number of urban air pollution. Cumulative strongest gas. The CO and CO2 car exhaust, HC, NO2, etc in immediate harm human body body health at the same time also QiDa damage human survival environment. According to recent car increase speed and fuel consumption level have experts predict that by 2020, China to 1.5 billion auto possession will break through in fuel consumption will break through the mark for 250 million tons, atmospheric pollution will also heavier. Energy and the environment will be more challenges, our government for tackling global climate change was a promise made by 2020, China unit of gross domestic product carbon monoxide emissions down 40% - more than 2005, no doubt to 50% of production, sales and after-sale link, will produce large amounts of carbon emissions car production also put forward higher request, car companies will get more attention, shouldering the important mission. Automobile industry to the energy conservation and environmental protection, conforms to our country energy supply and mass consumption level, can help to alleviate the strain, protect the environment, for implementing the national energy development strategy, speed up the construction of the reso
