下面参考图 1和图 2详细描述根据本发明实施例的燃油***,该燃油***适用于车辆, 具体地, 该车辆为具有内燃机的机动车辆。
根据本发明一个实施例的用于车辆的燃油***可以包括油箱油泵总成 1、 碳罐总成 2 和吸附控制装置 3。 应当理解, 油箱油泵总成 1 以及碳罐总成 2均已为现有技术, 因此这 里对于油箱油泵总成 1以及碳罐总成 2的具体构造以及工作原理不作详细描述。
如图 1所示, 吸附控制装置 3设在油箱油泵总成 1与碳罐总成 2之间, 用于控制从油 箱油泵总成 1输出给碳罐总成 2的油气流量, 从而使碳罐总成 2获得良好的吸附效果, 降 低车辆的排放。
根据本发明的一个实施例, 如图 2所示, 吸附控制装置 3可以包括缓冲室 31和冷却装 置例如下面将会提到的冷却室 32。 具体而言, 缓冲室 31具有进口 311和出口 312, 缓冲室 31的进口 311适于与油箱油泵总成 1相连以接收来自油箱油泵总成 1的燃油蒸汽 (简称油 气), 缓冲室 31的进口 311与油箱油泵总成 1可以直接相连, 当然优选地, 缓冲室 31的进 口 311与油箱油泵总成 1之间可以通过管路间接相连。缓冲室 31的出口 312适于与碳罐总 成 2相连以将缓冲室 31内的油气输出给碳罐总成 2。
缓冲室 31用于缓冲来自油箱油泵总成 1的油气, 降低输出给碳罐总成 2的油气速率, 从而提高碳罐总成 2的吸附效果, 降低排放。 冷却装置用于冷却缓冲室 31内的燃油蒸汽, 从而降低燃油蒸汽的温度, 由此可以进一步提高碳罐总成 2的吸附效果。
由此,根据本发明实施例的用于车辆的燃油***,通过在油箱油泵总成 1与碳罐总成 2 之间设置吸附控制装置 3, 从而可以降低从吸附控制装置 3输出给碳罐总成 2的单位时间 内的油气流量以及油气的温度, 进而可大大提高碳罐总成 2的吸附效果, 降低排放, 避免 出现排放超标的问题。
根据本发明的一个实施例, 如图 2所示, 冷却装置包括冷却室 32, 冷却室 32套设在缓 冲室 31的外面, 冷却室 32具有进液口 321和出液口 322, 进液口 321和出液口 322分别 适于与冷却源相连以在冷却源与冷却室 32之间形成循环冷却回路。 这里, "冷却源"可以 理解为可提供冷却介质如冷却水的介质源。
这样, 冷却源可向冷却室 32内持续提供冷却介质, 冷却介质通过间接换热可带走缓冲 室 31的部分热量, 从而降低缓冲室 31内油气的温度。
在该实施例中,冷却室 32的进液口 321与出液口 322可分别与车辆的发动机循环水路 相连, 例如与发动机的散热器相连。
但是, 本发明并不限于此, 在本发明的另一个实施例中, 冷却装置为冷却棒 (图未示 出), 冷却棒可以伸入到缓冲室 31内从而直接与缓冲室 31内的油气接触换热, 带走油气的 部分热量, 从而降低油气的温度。 冷却棒适于与冷却源相连以在冷却棒与冷却源之间形成 循环冷却回路, 这里的冷却源的含义与上述冷却室 32实施例中的冷却源的含义相同, 因此 不再赘述。
在该实施例中, 冷却棒为至少一个, 冷却棒优选以蜿蜒方式延伸, 换言之, 冷却棒为 蛇形或波浪形, 这样可以增加冷却棒与缓冲室 31内油气的接触面积, 增加换热效果。 在该 实施例中, 冷却棒适于与车辆的发动机循环水路相连, 例如与发动机的散热器相连。
需要说明的是,对缓冲室 31内的油气的冷却方式不限于上述的冷却室 32以及冷却棒, 对于其它可以实现冷却缓冲室 31 内的油气温度的装置和 /或方法, 均落入本发明要求保护 的范围内。
由于设置冷却装置的缘故, 缓冲室 31内的油气容易液化。 因此, 优选地, 参照图 1和 图 2所示, 缓冲室 31还设置有回油口 313, 回油口 313与油箱油泵总成 1之间连接有回油 通道 314, 这样液化后的燃油可通过回油通道 314回流油箱油泵总成 1内并重新进入循环, 并且缓冲室 31内由于部分油气液化, 因此缓冲室 31内压力降低, 从而可从油箱油泵总成 1吸入更多的油气。
优选地, 回油通道 314上设置有回油单向阀 315, 回油单向阀 315用于沿从回油口 313 朝向油箱油泵总成 1的方向单向导通回油通道 314。 换言之, 缓冲室 31内的燃油可通过该 回油单向阀 315流入到油箱油泵总成 1内, 而油箱油泵总成 1内的燃油或油气不能逆向通 过回油单向阀 315流入缓冲室 31内。
参照图 1和图 2所示, 缓冲室 31的出口 312与碳罐总成 2并非是直接相连的, 而是通 过中间管路间接相连的。 具体地, 燃油***可以包括第一油气流出管路 41和控制阀 54, 第一油气流出管路 41连接在缓冲室 31的出口 312与碳罐总成 2之间,控制阀 54设在第一 油气流出管路 41上用于控制第一油气流出管路 41的通断, 也就是说, 控制阀 54打开, 则 缓冲室 31内的油气可通过第一油气流出管路 41流向碳罐总成 2, 若控制阀 54关闭, 则油 气无法流向碳罐总成 2。 可选地, 控制阀 54可以是电磁阀, 由此控制方便。
进一步, 燃油***还可以包括第一单向阀 51, 第一单向阀 51 设在第一油气流出管路 41上用于沿从缓冲室 31朝向碳罐总成 2的方向单向导通第一油气流出管路 41, 通过设置 该第一单向阀 51, 可以避免碳罐总成 2内的油气逆向流回缓冲室 31。 应当理解的是, 第一 单向阀 51与控制阀 54如电磁阀可以是两个单独的阀, 该两个阀独立工作, 互不影响。 但 是, 同样可以理解的是, 第一单向阀 51与控制阀 54如电磁阀可以集成为一个阀, 如单向 电磁阀, 这对于本领域的普通技术人员而言, 应当是容易理解的。
根据本发明的进一步实施例, 如图 2所示, 燃油***还包括第二油气流出管路 42和第 二单向阀 52, 第二油气流出管路 42连接在缓冲室 31的出口 312与碳罐总成 2之间且与第 一油气流出管路 41并联设置,第二单向阀 52设在第二油气流出管路 42上用于沿从缓冲室 31朝向碳罐总成 2的方向单向导通第二油气流出管路 42。 其中, 第二单向阀 52的开启压 力大于第一单向阀 51的开启压力。
由此, 第二油气流出管路 42构成第一油气流出管路 41的保护回路, 在控制阀 54因故 障等原因关闭无法正常打开时, 缓冲室 31内的油气的压力将逐渐升高, 当压力达到一定值 时, 第二单向阀 52将被打开, 从而缓冲室 31内的油气可通过第二油气流出管路 42流向碳 罐总成 2, 避免油箱油泵总成 1以及缓冲室 31内压力过大而导致油箱油泵总成 1及缓冲室 31损坏。
而在控制阀 54正常工作时, 由于第一单向阀 51的开启压力较小, 因此第二油气流出 管路 42由第二单向阀 52封闭, 油气均通过第一油气流出管路 41流入到碳罐总成 2内。
进一步, 燃油***还包括气压平衡管路 43和第三单向阀 53, 气压平衡管路 43连接在 缓冲室 31的出口 312与碳罐总成 2之间且与第一油气流出管路 41和第二油气流出管路 42 并联设置, 也就是说, 气压平衡管路 43、 第一油气流出管路 41和第二油气流出管路 42三 条管路并联设置。 第三单向阀 53设在气压平衡管路 43上用于从碳罐总成 2朝向缓冲室 31 的方向单向导通气压平衡管路 43。
由此, 在油箱油泵总成 1及缓冲室 31内负压过大时, 碳罐总成 2内的空气和 /或油气 可通过气压平衡管路 43补充至缓冲室 31以及油箱油泵总成 1内, 避免由于负压过大而导 致缓冲室 31和油箱油泵总成 1损坏。
参照图 1和图 2所示,第一油气流出管路 41、第二油气流出管路 42以及气压平衡管路 43通过共用管路 45与碳罐总成 2相连, 并且燃油***还包括流量计 46, 流量计 46设在共 用管路 45上, 流量计 46与车辆的 ECU47 (行车电脑)相连且该 ECU47还与控制阀 54相连, 这样 ECU47根据流量计 46反馈的流量信号以及车辆发动机当前运行工况,可以控制控制阀 54的开闭, 从而实现加载量的控制, 使碳罐总成 2的性能处于较优的工作状态, 提高碳罐 总成 2的吸附能力。
需要说明的是, 在图 1和图 2的示例中, 其第一油气流出管路 41为主流出管路, 该管 路上设置有控制阀 54和第一单向阀 51, 但是可以理解的是, 在该示例中, 第一油气流出 管路 41上也可以取消控制阀 54而改为流量调节阀, 流量调节阀可以打开或关闭第一油气 流出管路 41, 且在流量调节阀处于打开状态时其可改变自身开度从而调节第一油气流出管 路 41上的油气流量, 从而更好地适应碳罐总成 2, 使得碳罐总成 2的吸附效果时刻处于最 佳状态。
但是, 本发明并不限于此, 出于降低成本以及简化结构等方面的考虑, 根据本发明的 一个可选实施例, 燃油***还包括第三油气流出管路和流量调节阀(图未示出), 即在该实 施例中, 连接缓冲室 31与碳罐总成 2的管路可以仅为该第三油气流出管路, 第三油气流出 管路连接在缓冲室 31的出口 312与碳罐总成 2之间,流量调节阀设在第三油气流出管路上 用于调节流经第三油气流出管路的油气流量。 在该实施例中, 第三油气流出管路上可设置 有流量计, 流量计可与车辆的 ECU相连且该 ECU还与流量调节阀相连, 这样 ECU根据流量 计反馈的流量信号以及车辆发动机当前运行工况, 可以控制流量调节阀的开闭或开度, 从 而实现加载量的精确控制, 使碳罐总成 2的性能处于较优的工作状态, 提高碳罐总成 2的 吸附能力。
整体而言, 根据本发明一个优选实施例的燃油***, 其缓冲室 31可以有效减缓油箱内 燃油蒸汽的加载速度, 冷却室 32可以有效降低燃油蒸汽温度, 控制阀 54可以有效控制燃 油蒸汽的加载量, 从而达到提升碳罐总成 2工作能力的目的。 下面简单描述根据本发明实施例的车辆。
根据本发明实施例的车辆包括燃油***, 该燃油***为根据本发明上述实施例中描述 的燃油***。
应当理解, 根据本发明实施例的车辆的其它构成例如发动机、 变速器、 差速器等均已 为现有技术, 且为本领域的普通技术人员所熟知, 因此这里不再一一详细描述。
在本说明书的描述中, 参考术语 "一个实施例"、 "一些实施例"、 "示例"、 "具体示 例"、 或 "一些示例"等的描述意指结合该实施例或示例描述的具体特征、 结构、 材料或者 特点包含于本发明的至少一个实施例或示例中。 在本说明书中, 对上述术语的示意性表述 不必须针对的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材料或者特点可以 在任何的一个或多个实施例或示例中以合适的方式结合。 此外, 本领域的技术人员可以将 本说明书中描述的不同实施例或示例进行接合和组合。
尽管上面已经示出和描述了本发明的实施例, 可以理解的是, 上述实施例是示例性的, 不能理解为对本发明的限制, 本领域的普通技术人员在本发明的范围内可以对上述实施例 进行变化、 修改、 替换和变型。
