Description

双燃料汽车的燃料供给系统 技术领域
本发明涉及一种汽车的燃料供给系统， 尤其涉及一种应用在双燃料汽车上 的燃料供给系统。 背景技术
随着工业技术的发展， 汽车成为人们重要的代步工具。 目前汽车的主要燃 料为汽油， 为不可再生的燃料， 而且对环境会造成污染。 新型的燃料是人们所 期待的， 现在汽车发动机燃料的来源开始朝多元化发展， 双燃料汽车已经越来 越多的被人们所重视。 以优势能源代替稀缺能源， 以新能源代替传统能源， 是 现在汽车燃料的主要研究方向， 双燃料的汽车已经成为未来汽车发展的趋势。 如中国专利申请： "汽车双燃料供给转换装置 （CN2391994)", 是针对一种汽油 和液化石油气混合的双燃料汽车设计的燃料供给系统， 其为了提高了双燃料的 燃料效率， 其燃料供给系统的燃料转换是通过汽油电磁截止阀和液化石油气电 磁截止阀完成的。 对于燃料和燃气混合的双燃料汽车， 其一般是在原有汽油车 上新增一套燃气供给装置， 通过各类阀体的切换， 将燃气输送至发动机， 而汽 油的供给系统保持不变。 发明的公开
本发明主要是提供一种布置整齐， 方便辨识和安装系统部件， 便于维护和 检修， 充分利用了车辆底板有限空间的双燃料汽车的燃料供给系统； 解决现有 技术存在的所需安装布置空间较大， 布置不合理， 系统部件安装、维护不方便， 不易辨识等的技术问题。
本发明同时还提供一种制造工艺简单、 两燃料箱间隔离性好， 安装方便、 生产成本低、 提高生产效率的双燃料汽车的燃料供给系统； 解决现有技术所存 在的双燃料汽车使用两个独立的油箱， 生产成本高、 生产效率低、 在汽车上布 置不合理的技术问题。
本发明的上述技术问题主要是通过下述技术方案得以解决的： 一种双燃料 汽车的燃料供给系统， 包括油箱， 所述的油箱连接有进油和回油管路， 所述的 进油和回油管路连接着进气歧管总成， 所述的油箱为一个整体式油箱， 油箱包 含两个子油箱， 每个子油箱对应连接有一套进油和回油管路， 两套进油和回油 管路在车体底部左右两侧对称布置， 进油和回油管路与其对应的子油箱位于同 一侧。 整体式油箱结构简单， 其内分别设置两个子油箱， 两个相互独立而又连 成一体的燃料箱可以采用一次成型的制造方式， 采用一个模具就可以一次生产 出带有一大一小两个腔的连体油箱， 提高了生产效率， 降低了生产成本， 减少 了在汽车上的装配工序。 两个子油箱分别连接不同的油路系统， 且子油箱和其 对应的进油和回油管路位于同一侧， 如汽油油箱位于油箱的左侧， 与汽油油箱 相连的进油和回油管路也布置在汽车底部的左侧， 而甲醇油箱位于右侧， 其对 应的进油和回油管路也布置在汽车底部的右侧， 两套进油和回油管路相对称， 方便区分， 布置整齐， 有效的利用车辆底板的有限空间， 充分考虑了拆装和维 修的方便性， 同时将一种燃料的所有部件都布置在同一侧， 方便辨识。
作为优选，所述的进气歧管总成包含有固定于进气歧管上的前后两套油轨， 每套油轨的进油口和回油口位于同一侧， 作为外接进油和回油管路的连接端， 两套油轨的连接端分列在进气歧管的两侧， 两套油轨的连接端与其对应的进油 和回油管路位于同一侧。 油轨的进油口和回油口位于同一侧， 方便外接进油和 回油管路， 减少了软管的数量， 降低了成本， 减少了装配工序。 同时每套油轨 的连接端与各自的进油和回油管路对应， 如汽油油轨的连接端位于左侧， 与位 于车身底板左侧的汽油进油和回油管路对应； 甲醇油轨的连接端位于右侧与位 于车身底板右侧的甲醇进油和回油管路对应。 方便进油和回油管路与油轨的连 接， 便于辨识和安装， 提高了工作效率。
作为优选， 所述的整体式油箱的两个子油箱中的其中一个为甲醇燃料箱， 另外一个为汽油燃料箱，所述的甲醇燃料箱的容积是汽油燃料箱容积的 2. 5〜5 倍， 甲醇燃料箱和汽油燃料箱通过横向设置的连接带形成一体化的连体结构， 在两个子油箱上均设有加料口和加料排气口， 在加料口内设有单向阀。 通过设 置一大一小的两个独立的燃料箱， 为汽车发动机采用双燃料提供了可能。 同时 对于甲醇汽车来说， 由于主燃料为甲醇， 因此， 将大燃料箱设置为甲醇燃料箱， 而作为辅助作用的汽油则使用小燃料箱， 两个燃料箱之间仅有一横向设置的连 接带连接， 这样可以将两个燃料箱完全隔离。 同时， 两个相互独立而又连成一 体的燃料箱可以采用一次成型的制造方式进行制造。
作为优选， 在甲醇燃料箱上方设有甲醇取气管、 甲醇燃料泵及甲醇液位传 感器； 在汽油燃料箱上设有集成式汽油泵， 集成式汽油泵包括汽油燃料泵与汽 油液位传感器。 该燃料箱上设置甲醇燃料泵及甲醇液位传感器， 甲醇泵用于将 一定压力的甲醇输送到发动机， 甲醇液位传感器实时监测燃料剩余量信息； 而 起辅助作用的汽油则使用小燃料箱， 考虑到小燃料箱本身容积较小， 其上的安 装空间有限， 因此在小燃料箱上设置集成式汽油泵， 该泵集成了汽油燃料泵及 汽油液位传感器， 分别用于泵送汽油和实时监测汽油剩余量信息， 因此， 合理 的利用了有限的空间位置， 实现了所需的功能。
作为优选， 甲醇燃料箱和汽油燃料箱上均设有翻车阀， 每个翻车阀连接着 一个导气管， 两根导气管通过三通阀连接着蒸发回收管， 蒸发回收管连接在碳 罐的燃料蒸汽吸附口上， 碳罐上的燃料蒸汽脱附口通过碳罐控制阀与发动机相 连。碳罐是装有活性碳的吸收罐， 吸附燃油箱燃油蒸发物。当发动机不工作时， 排出的燃油蒸气进到吸收罐中， 当发动机开动时， 新鲜空气吸收罐的内部碳料 层被吸入， 携脱附出的燃油蒸气通向发动机。 两个子油箱上的翻车阀， 可在车 辆发生倾斜或翻车时， 避免燃油外泄而带来的危险。 两个翻车阔各连接一个导 气管，将油箱内的蒸汽收集后由导气管导出，经过三通阀连接到蒸发回收管内， 然后通过吸附口连接到碳罐内； 脱附后的蒸汽， 由碳罐控制阀控制， 输入发动 机与可燃混合气一起燃烧， 减少燃料的蒸发排放。 两个子油箱内的燃油蒸汽由 一套蒸汽回收装置进行回收， 结构简单， 充分利用了有限的空间， 拆装方便。
作为优选， 在所述的汽油燃料系统上配备有开关汽油燃料箱的汽油燃料箱 钥匙， 在所述的甲醇燃料系统上配备有开关甲醇燃料箱的甲醇燃料箱钥匙， 所 述的甲醇燃料箱的钥匙同时为汽车的点火开关钥匙。 两把钥匙控制两个油箱， 分开使用， 方便区分和控制， 避免两种燃料的错加。
作为优选， 在车体的外壳的两侧对称的各设有一个注油口， 每个注油口通 过加油管总成与油箱内的子油箱相连， 每个注油口与其对应的子油箱、 进油和 回油管路位于同一侧。 在车体驾驶舱内的显示仪表上设有两个燃料液位显示装 置、 两个燃料报警装置和一个综合的燃料状态指示装置， 所述两个燃料液位显 示装置和两个燃料报警装置在显示仪表上左右对称布置， 与车体底部的两套进
