乘用车燃油经济性分析研究汽车制造与装配专业摘要汽车燃油经济性是汽车的一个重要性能,也是每个拥有汽车的人最关心的指标之一。它关系到每个人的切身利益,在汽车说明书中大概最引人注意的技术规格也是燃油消耗。由于要求节约能源和减少消耗能源时产生的温室效应的副作用,所以降低汽车燃油消耗似乎就成了汽车制造者和使用者的一个永恒的课题。汽油的燃油经济性指标与发动机的好坏和汽车的自重、车速及各种运动阻力、个人的驾驶技术、传动系的效率及燃油种类等都有关系,因而在数值上往往与实际情况有差别。所以燃油经济性与许多因素都密切相关。关键词:燃油经济性节约能源发动机驾驶技术传动效率AbstractAutomobilefueleconomyisanimportantperformanceofthecar,itisoneoftheindicatorsofeachcarownersaremostconcernedabout.Itisrelatedtothevitalinterestsofeachperson,inthecarmanualisperhapsthemostnotabletechnicalspecificationsandfuelconsumption.Duetotherequirementsofsavingenergyandreducingthesideeffectsofgreenhouseeffectofenergyconsumption,soreduceautomobilefuelconsumptionseemstohavebecomeaneternaltopicofautomobilemanufacturersandusers.Havetherelationshipofgasolinefueleconomyandenginequalityandvehicleweight,speedandresistancetomotion,individualdrivingtechnology,transmissionefficiencyandfueltypes,sooftenwiththeactualsituationinthenumericaldifference.Sothefueleconomyandmanyfactorsarecloselyrelated.Keywords:fueleconomyenergysavingenginedrivingthetransmissionefficiency目录第1章能源与汽车节能概述...........................................................11.1能源概述.....................................................................................................................11.2汽车节能概述.............................................................................................................2第2章汽车燃油经济性评价指标及实验方法...............................52.1汽车燃油经济性评价指标......................................................................................52.2汽车燃油经济性试验方法.........................................................................................6第3章影响汽车燃油经济性的主要因素.......................................93.1汽车燃油的能量消耗.................................................................................................93.2影响汽车燃油经济性的主要因素...........................................................................10第4章整车的节能原理及技术.....................................................154.1传动系统的优化.......................................................................................................154.2减少汽车行驶中的阻力...........................................................................................164.3减轻汽车的重量.......................................................................................................244.4润滑油的使用...........................................................................................................254.5发动机的节能技术...................................................................................................28第5章汽车使用中的节能技术.....................................................335.1汽车起步加速节能...................................................................................................335.2汽车行驶途中的速度控制与换档操作...................................................................34致谢...........................................................................
