Description
技术领域
本实用新型涉及内燃发动机领域,具体涉及一种纯氧醇类内燃双能发动机系统。
背景技术
目前汽车内燃发动机、航空用和船用内燃机及内燃机发电机组其发动机的燃料主要是汽油和柴油,都为矿物理化配制油。这些燃料的获得、炼制和在内燃机里的燃烧排放都对自然界造成不可逆转的污染和破坏。为提高内燃发动机工作效率,现代内燃发动机不管是汽油机还是柴油机大多加装了涡轮增压器,用发动机工作燃烧排出的废气推动排气涡轮旋转带动压气涡轮将更多的空气压入发动机的工作缸内,利用增压空气中五分之一的氧气来配合多喷入的相应比例的燃料完全燃烧,提高发动机的功率和效率,而增压空气中五分之四的氮气非但不能助燃还消耗浪费了燃料,因此可用液态纯氧来代替增压空气作为内燃机的助燃剂。液态氧从空气中极易获得,价格低廉。液氧的保存和使用控制又和目前内燃发动机大量使用的液态天然气极为相似,并在医学、冶金和航天工业上已广泛应用。因此采用液态纯氧作为内燃发动机的助燃剂在使用控制上无技术难度。
目前的汽油发动机所用的汽油大多已加入了一定比例的乙醇,并已有乙醇汽油国家标准,全乙醇汽车也问世有几十年了。近年柴油机也用上了甲醇。甲醇柴油中甲醇的比例已高达90%。醇是公认的绿色燃料,生态植物提炼的甲醇、乙醇燃烧后的产物只有水和二氧化碳。水是生命之源,二氧化碳是植物吸收太阳能进行光合作用创造生命集聚能量的必不可少的合成物。从生态循环能量再生的角度看,醇是源于太阳能,能够环保循环再生的优质燃料。醇燃料的崛起将大大推动农业、林业、制醇业、肥料饲料业、制氧业、物流业、包装机械行业及转基因技术的发展,大量生产的价格远低于汽油柴油。
对于不使用汽油、柴油而使用矿物重油、天然气的燃气发电机组来说,使用了醇类增氧将彻底告别由于矿物重油、天然气燃料里的杂质所带来的对燃气轮机自身的腐蚀、结垢和污染,高了燃气轮机发电机组的机械使用寿命降低维护费用,也大大增加了输出发电功率和热效率,彻底告别对大气的污染。
实用新型内容
由鉴于此,本实用新型的目的是发明一款使用新型生态燃料非增压高效双能发动机系统,即纯氧醇类内燃双能发动机系统。
本实用新型采用的技术方案为:一种纯氧醇类内燃双能发动机系统,包括发动机、进气管、排气管、ECU、燃料罐和液氧罐,所述的排气管中设有发电机,燃料罐通过燃料喷嘴连接发动机,液氧罐通过液氧喷嘴连接进气管,在排气管上设有氧含量传感器,所述的ECU分别连接发电机、氧含量传感器、燃料喷嘴和液氧喷嘴。
进一步,所述的液氧罐和燃料罐为可拆卸模块。
进一步,所述的液氧罐和燃料罐采用快速接口连接发动机。
本实用新型的有益效果为:
1、纯氧醇类双能发动机系统无排放污染,纯氧、醇类制造过程也没有环境污染。
2、车辆采用纯氧醇类双能发动机系统安全性提高,补充燃料方便。
3、对于不使用汽油、柴油而使用重油、天然气的燃气轮机发电机组来说,使用醇类增氧系统将彻底告别由于重油、天然气杂质所带来的对燃气轮机自身的腐蚀、结垢和污染,提高了燃气轮机发电机组的使用寿命,也大大增加了输出功率和热效率
本实用新型的其他优点、目标和特征在某种程度上将在随后的说明书中进行阐述,并且在某种程度上,基于对下文的考察研究对本领域技术人员而言将是显而易见的,或者可以从本实用新型的实践中得到教导。本实用新型的目标和其他优点可以通过下面的说明书或者附图中所特别指出的结构来实现和获得。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型作进一步的说明。
如图1所示,本实用新型包括发动机1、排气管3和进气管4,在排气管3中安装有一个发电机2,可以通过发动机产生的废弃驱动发电机2运转发电。液氧存储在液氧罐8中,通过液氧喷嘴10喷射到进气管4中,燃料存储在燃料罐中,直接通过燃料喷嘴9喷射到发动机的气缸中。ECU 6与发动机各部分形成闭环系统,通过收集发电机功率以及设置在排气管3中的氧含量传感器5,控制燃料喷嘴9和液氧喷嘴10的动作,进而调控燃料和液氧的喷入量。
该发动机用的燃料是醇类,优先全乙醇和高浓甲醇,可用醇直接替换汽油、柴油或液化天然气成为发动机的燃料。通过转基因技术大量生产用于提炼醇的农作物和木材在全自动制醇设备里吸收太阳能发酵蒸馏出醇后直接灌入特种安全小罐里,由物流特种车直接送到汽车车上换罐。醇燃料供液、喷射、着火方式及电子控制稍加设计改动即可基本沿用原内燃电喷发动机的体系。在制醇过程中产生的废弃物可分离成饲料或肥料的原料,加入规定的其他原料可制成生态环保的饲料和肥料。
再增加一套上述类似的装置配以液氧蒸发器和氧气稳压器,在发动机向缸内喷射醇类燃料的同时向发动机机体内或发动机进气管内喷射纯氧助燃,使燃料充分完全燃烧,提高燃烧热化学反应的强度和效率,用检测排气中氧含量的方法控制纯氧的喷入量,节省燃料和氧气。由于氧气量比原来自然吸气式发动机增加了4倍,比增压发动机增加了1-2倍,故阻碍醇发动机发展的最大障碍醇的热值比汽、柴油低四分之一的问题也就圆满解决。各种醇类发动机的升功率都将大大超过原来的增压发动机。
对于非移动式应用的内燃发动机来说除了液氧气化喷射方式以外也可向发动机机体内或发动机进气管内直接喷射加压纯氧气,以节约氧气液化功耗。
由于使用醇类燃料,因此可以取消原发动机接在排气管上为排放达标所用的一切废气环保处理装置,因为它们对发动机排放的水和二氧化碳已没有存在的必要。取消原发动机增压过程中为降低增压空气温度的中冷系统,取消原有的发电机,用涡轮发电机替换涡轮增压器,由发动机燃烧排放的废气推动涡轮发电机发电,将发动机本来全部排出废弃的热能和动能高效直接转化为电能,大幅度提高现有内燃机的功率和热效率,成为新一代既能输出机械能又能输出电能的纯氧醇类内燃双能发动机系统。
原发动机的ECU需根据新发动机的工作特性进行数据更新,供液、喷射、着火方式及电子控制稍加设计改动即可基本沿用。增加电子纯氧喷射系统控制及发电及电压控制系统,也可单设电子控制单元控制纯氧喷射系统和发电及电压控制系统,与原ECU进行数据通讯共同管理纯氧醇类内燃双能发动机系统。
配合整车轻量化安全节能思想,根据油箱容积减量设计理念,减轻整车满载实际总重,大幅度缩小原油箱容积设计,变加燃料为送燃料。将长方体的原油箱改为细长圆柱形不锈钢内胆碳纤维加强等安全小罐。安全小罐可以采用标准的快换接头和快速装卸设计,便于更换燃料罐和液氧罐。
由于醇类内燃发动机的排放是环保的,所以原发动机接在排气管上为排放达标所用的一切废气环保处理装置如三元催化器、颗粒捕捉器等都可取消,同时取消增压过程中为降低增压空气温度的中冷系统,取消原来的发电机,用涡轮发电机替换涡轮增压器,由发动机燃烧排放的废气推动涡轮发电机的涡轮带动发电机发电,将发动机本来全部排出废弃的热能高效直接转化为电能,大幅度提高现有内燃机的功率和热效率,整个系统在成本价格上也因取消了增压机及增压系统的中冷系统和汽油机的三元催化还原系统 、柴油机的废气颗粒捕捉器等,一次性投入大幅降低。
