Description

双转子发动机
技术领域
本发明涉及一种发动机， 特别是一种具有两个转子的双转子发动机。
背景技术
目前使用较普遍的发动机为往复活塞式发动机， 也有使用转子发动机的。 为了提高发 动机的效率， 人们发明了双转子发动机。 双转子发动机的类型多种多样， 其中 "剪刀式" 双转子发动机是较常见的一种类型， 其结构包括： 机架、 安装在机架上的缸体组件、 安装 在缸体内的第一转子、第二转子， 以及控制器、用于输出动力的传动输出机构、控制器等。 其中每个转子上对称设有一对扇形活塞， 两个转子安装在同一根输出轴上， 两个转子的两 对扇形活塞相互交叉布置， 这样缸体内的空腔由 4个扇形活塞分隔成 4个工作腔。在转子 控制机构的控制作用下，扇形活塞转动一周，各个工作腔共作 4次功，可大幅度提高效率。 所以在双转子发动机中， 转子控制机构起着关键作用， 其要控制两对扇形活塞按照所需精 确时间顺序控制转子在精确位置停止转动或开始转动， 防止转子反转； 同时在启动发动机 时， 要保证转子保持精准的工作状态。
传统双转子发动机中的控制器结构包括步进式、 差速式、 凸轮滚子式、 棘轮弹簧擒纵 机构等各种类型。歩进式、差速式、凸轮滚子式等转子控制机构均不能使输出轴匀速运转， 根本无法投入实际应用。 而设计有棘轮弹簧擒纵机构等防转子反转措施的发动机， 其可靠 性基本为零。所以传统的不同设计的各种双转子发动机， 因控制器实际上无法做到精确控 制转子旋转的工作状态， 所以均不能够投入实际应用。

下面将详细描述本发明的具体实施例。应当注意，这里描述的实施例只用于举例说明， 并不用于限制本发明。
本发明的双转子发动机包括缸体组件、传动输出机构、转子控制机构以及润滑系 统。
参见图 1 - 1至图 1 - 1 1。本发明的双转子发动机中的缸体组件包括固定连接在基座 (图中未示出） 上或与基座一体设计的管形缸体 6、 穿过管形缸体 6且两端通过轴承 连接于基座的中心支撑轴 7、 第一转子 l a和第二转子 l b。 其中， 管形缸体 6左上侧 设有火花塞 9， 管形缸体 6下面分别连接有进气口 10和排气口 1 1。 本发明的发动机 中， 可以沿径向进、 排气， 也可以沿圆周方向进、 排气。 管形缸体 6的前、 后端部分 别固定连接有圆盘形的前端盖 5a、 后端盖 5b。 在前、 后端盖与缸体 6之间分别设有 密封垫， 以保证缸体 6的密封性能。 前端盖 5a、 后端盖 5b中央分别设有转子颈孔。
第一转子 l a包括内圆柱缸体 99a (见图 1 -8 ) 、 连接于该与内圆柱缸体 99a的一 端并与其一体的第一转子颈 20a和对称固定连接在内圆柱缸体 99a上的两个第一扇形 活塞 17a。 第一转子上的第一扇形活塞 17 a的扇形角最佳为 40°， 该角度优选方案一 般在 35°-45°之间； 当扇形角小于 35°时， 转子厚度太薄， 对燃烧室的容积、 转子的受 力、 温度、 密封性能等影响较大。 第一转子颈 20a的直径小于内圆柱缸体 99a直径。 第一扇形活塞 17a凸出内圆柱缸体 99a—部分， 第一扇形活塞 17a凸出部分与第一转 子颈 20a分别分布在内圆柱缸体 99a的两端。 内圆柱缸体 99a在不与第一转子颈 20a 连接的一端， 尽可能靠近底面圆周处设有环形凹槽 19a， 用以减小纵向密封深度。 第 一转子颈 20a与内圆柱缸体 99a连接位置， 内圆柱缸体 99a的圆周上设有密封槽。 第 一扇形活塞 17a与内圆柱缸体 99a结合处除外， 环绕第一扇形活塞 17a—周有两道平 行布置的密封槽。 在第一转子 l a中轴线位置设有用于套装到中心支撑轴 7上的中心 支撑轴孔 21 a。 第一扇形活塞 17a的两个对称侧面上分别设有凹向第一扇形活塞 17a 内的两个凹陷 15a。 第一扇形活塞 17a的两侧面在靠近内圆柱缸体 99a的根部具有减 震降噪面 14a。
第二转子 l b的结构与第一转子 l a相同， 包括内圆柱缸体 99b、 连接于该与内圆 柱体的一端并与其一体的第二转子颈 20b (见图 1 -5 ) 和对称固定连接在内圆柱体上 的两个第二扇形活塞 17b。 第二转子 l b的中轴线位置设有中心支撑轴孔。 第二扇形 活塞 17b的两个对称侧面上分别设有凹向第二扇形活塞 17b内的两个凹陷。第二扇形 活塞 17b的两侧面在靠近内圆柱体的根部具有减震降噪面。内圆柱缸体 99b和第一扇 形活塞 17a上布置有密封槽。 第一转子 la和第二转子 lb通过各自的中心支撑轴孔固定套装在中心支撑轴 7 上。 第一转子 l a、 第二转子 lb在发动机中的作用是一样的， 只是在同一时刻所处的 工作状态不一样。 第一转子 la、 第二转子 lb在中心支撑轴 7上的安装方向相反： 第 一转子 la、 第二转子 lb的内圆柱缸体 99b位于缸体 6内， 二者的转子颈分别由前端 盖 5a、 后端盖 5b的转子颈孔伸出缸体 6外。 第一转子 la、 第二转子 lb的扇形活塞 17a, 17b位于缸体 6内， 且相互交叉布置。 第一转子 la的内圆柱缸体 99a和第二转 子 lb内圆柱缸体 99b接触面上各自设有一个减小纵向密封深度的环形密封凹槽 19， 环形密封凹槽 19对正，嵌入 0形密封圈，使两个转子的纵向接触面上实现了气密性。 相邻的第一扇形活塞 17a和第二扇形活塞 17b 的相邻侧面上的两个凹陷形成燃烧室 15， 燃烧室 15的朝向火花塞 9或喷油口位置设有缺口。 当空气被压缩后就储存在相 应的燃烧室 15内， 燃烧室 15与进气工作室的体积比为发动机的压缩比。沿轴线垂直 面上优选的燃烧室形状为一头大一头小的卵形， 并且在靠近缺口处的容积较大， 在靠 近中心支撑轴 7处的容积相对较小。 如图 1 -12、 图 1 - 13所示， 沿轴线平行面上然燃 烧室 15凹陷可以是对称布置的， 燃烧室 15凹陷最深处也可以是非对称布置的， 而是 在靠近转子内圆柱缸体有一个偏置， 使转子的受力条件更好。 安装在中心支撑轴 7 上的两个转子的相邻的两个扇形活塞根部的两个减震降噪面接触配合，以减小转子工 作过程中相互碰撞而产生的振动和噪音。 由于越靠近中心支撑轴 7位置， 转动的角速 度越小， 故减震降噪面可大幅度减小振动和噪声。
参见图 1 -1、 图 1-2、 图 1 -3和图 1 -4。 其中 A表示做功冲程， B表示排气冲程， C表示进气冲程， D表示压缩冲程。 第一转子 la和第二转子 lb的扇形活塞的扇形角 设定为 40度， 做功冲程对应的角度为 100度。本发明的双转子发动机的做功过程为： 图 1-1 表示本发明的双转子发动机开始做功图。 这时， 第一转子 la被控制机构 锁止到缸体 6上 （图 1 -1中的竖直位置） , 第二转子 lb可以自由旋转。 第一转子 la 和第二转子 lb的其中一对相邻的第一扇形活塞 17a和第二扇形活塞 17b紧靠在一起 将缸体 6 内的空腔分成两个工作室， 对应启始阶段的两个冲程： 排气冲程 B和压缩 冲程 D。 形成于该第一扇形活塞 17a和第二扇形活塞 17b之间的燃烧室 15正对缸体 6上的火花塞 9。
见图 1 -2、 图 1-3和图 1 -4。 当火花塞 9点火， 燃烧室 15内含有燃料的压缩空气 膨胀推动能够自由旋转的第二转子 l b旋转做功， 所做的功由传动机构输出。 第二转 子 l b做功过程中， 第二扇形活塞 17b与第一扇形活塞 17a分离， 将缸体 6内的空腔 分成 4个工作室， 对应 4个冲程： 做功冲程 、 排气冲程8、 进气冲程。、 压缩冲程 D， 由进气口 10吸入空气， 排气口 1 1排出废气。 第二转子 lb的做功行程对应的旋 转角度是 100度。当第二转子 l b旋转至其第二扇形活塞 17b与第一转子 la的第一扇 形活塞 17a紧密接触时， 制机构控制第一转子 l a解锁，第一转子 la和第二转子 l b 依靠惯性、 飞轮的作用共词旋转 40度， 这时第二转子 lb到达竖直位置， 代替了第一 转子 l a的初始位置。 此时， 第二转子 l b被控制机构锁止到缸体 6上， 第一转子 l a 可以自由旋转。第一转子 l a和第二转子 lb的另一对相邻的第一扇形活塞 17a和第二 扇形活塞 17b紧靠在一起，形成于该对第一扇形活塞 17a和第二扇形活塞 17b之间的 燃烧室 1 5正对缸体 6上的火花塞 9。 火花塞 9点火， 重复上述做功过程， 如此循环 往复。
参见图 2- 1。 本发明中的传动输出机构包括： 传动输出轴 8、 第一转子齿轮 2a、 第一传动齿轮 3a、 第二转子齿轮 2b、 第二传动齿轮 3b。 其中
传动输出轴 8设置在缸体 6外并与中心支撑轴 7平行，传动输出轴 8的两端分别通过 轴承可转动安装在基座上， 传动输出轴 8的两端也可直接固定安装在基座上。
第一转子齿轮 2a是圆柱斜齿轮， 套装在第一转子的转子颈上， 用花键和键槽固 定连接。
第二转子齿轮 2b是圆柱斜齿轮， 套装在第二转子的转子颈上， 用花键和键槽固 定连接。
第一传动齿轮 3a、 第二传动齿轮 3b分别通过花键和键槽固定连接在传动输出轴 8上。 第一传动齿轮 3a与第了转子齿轮 2a啮合配合， 第二传动齿轮 3b与第二转子 齿轮 2b啮合配合。
参见图 2 - 4， 第一转子齿轮 2a和第一传动齿轮 3a的周长有严格要求： 以转子 齿轮为 360°计， 第一传动齿轮 3a的周长等于转子齿轮周长的一半加上第一转子齿轮 2a做功所运转角度对应的周长。 或者是， 第一传动齿轮 3a的周长等于 360°减去第一 转子齿轮 2a的两个扇形活塞所占角度之差对应的第一转子齿轮 2a的周长。两种计算 方法所得结果相同。
参见图 2-2、 图 2-3、 图 2-4、 图 2-5。本发明中的第一转子齿轮 2a具有齿顶圆 281 和齿根圆 271。 第一传动齿轮 3a具有齿顶圆 282和齿根圆 272。 相互啮合的第一转子 齿轮 2a和第一传动齿轮 3a的两个齿顶圆 281， 282有两个交汇点 251、 252。 分别通 过两个交汇点 251、 252与第一转子齿轮 2a的圆心 CM所作的两条直径线 φ、 d2分别 在第一转子齿轮 2a的齿顶圆 281上有两个交汇点 253、 254。 4个交汇点将齿顶圆 282 分成四段圆弧。其中对称布置的两段弧长， 即交汇点 251与 252之间的弧长以及交汇 点 253与 254之间的弧长为第一转子齿轮 2a上缺齿部分 24的圆周长度：而对称布置 的两段弧长，即交汇点 251与 253之间的弧长以及交汇点 252与 254之间的弧长为第 一转子齿轮 2a上有齿部分的圆周长度， 两段有齿圆弧在起始位置的齿形完全一致， 转子齿轮和传动齿轮啮合位置是固定的，转子齿轮和传动齿轮上相互啮合的齿是一一 对应的关系。 缺齿部分 24等同于第一转子齿轮 2a与第一传动齿轮 3a啮合的部分。 缺齿部分 24的形状为第一转子齿轮 2a与第一传动齿轮 3a啮合情况下， 由二者的齿 顶圆 281， 282围成的区域， 见图 2-4中的剖面线部分。 设计缺齿部位 24是为了保证 在需要时转子齿轮停止而传动齿轮转动时， 传动齿轮的运转不受转子齿轮干涉。 当转 子停止转动时， 转子上的缺齿位正对传动齿轮， 这时传动齿轮的运转不受干涉。 参考 转子齿轮与传动齿轮啮合时两个齿轮的齿高、齿厚、齿距等因素转子齿轮缺齿长度和 高度范围可以略长或略大于上述的距离，转子齿轮缺齿部位的高度设计以转子齿轮停 转时不影响传动齿轮旋转为原则。
第一转子齿轮 2a在其圆柱基体的一端向外延伸有凸环 26， 该凸环 26的外圆周 面位于第一转子齿轮 2a的齿根圆位置，在凸环 26的外圆周面上对称设有两个转子齿 轮定位直齿 50， 转子齿轮定位直齿 50的齿高等于第一转子齿轮 2a的齿高。 两个转 子齿轮定位直齿 50呈中心对称布置， 分别设置在靠近两个缺齿部分 24位置， 以旋转 方向为前， 转子齿轮定位直齿 50位于转子齿轮缺齿部分 24的后方， 并紧邻该缺齿部 分 24。 需要指出的是转子齿轮与传动齿轮采用直齿传动时不需要凸环和定位直齿设 计。
本发明中的第二转子齿轮 2b与第一转子齿轮 2a相同， 不再赘述。
本发明中， 与转子齿轮啮合配合的传动齿轮可以是完整的圆柱斜齿轮， 没有缺齿 部分； 传动齿轮也可以设缺齿部分。第一转子齿轮 2a有齿的两段圆弧， 即交汇点 251 与 253之间的圆弧以及交汇点 252与 254之间的圆弧，这两段圆弧上的齿在圆弧起始 位置的齿形完全一致。 第一转子齿轮 2a上有齿的圆弧与传动齿轮上始终是固定位置 的一段圆弧相啮合。在传动齿轮上不参与啮合的部分， 如果在齿形设计上与参与啮合 的部分有冲突， 那么该部分也可以设计为无齿结构。
如图 2-5、 图 2-6所示， 本发明中的第一传动齿轮 3a在其圆柱基体的一端向外延 伸有凸环 44 , 该凸环 44的外圆周面位于第一传动齿轮 3a的齿根圆位置， 凸环 44上 设有一个传动齿轮定位直齿 51， 传动齿轮定位直齿 51 的齿高等于第一传动齿轮 3a 的齿高。当第一转子齿轮 2a和第一传动齿轮 3a分别在中心支撑轴 7上和传动输出轴 8上安装好后， 当第一转子 l a的转子控制机构设定在正时解除锁止状态上时， 第一 转子齿轮 2a上的其中一个转子齿轮定位直齿 50与第一传动齿轮 3a上的传动齿轮定 位直齿 51紧挨着。 当第一转子齿轮 2a开始旋转时， 转子齿轮定位直齿 50受第一传 动齿轮 3a上的传动齿轮定位直齿 51 的阻挡作用， 使第一转子齿轮 2a不能继续向前 转动， 从而保证转子齿轮和传动齿轮相啮合的齿一一对应， 不会发生错位。 当传动齿 轮采用圆柱直齿轮时， 可以不必设计转子齿轮定位直齿 50和传动齿轮定位直齿 51。
本发明中的第二传动齿轮 3b与第一传动齿轮 3a相同， 不再赘述。
当把第一转子 l a的转子控制机构设定在正时解除锁止状态时，第一转子 l a和第 二转子 l b上相邻的第一扇形活塞 17a和第二扇形活塞 17b是紧靠在一起， 这时第二 转子齿轮 2b上的转子齿轮定位直齿 50与第一转子齿轮 2a上转子齿轮定位直齿 50之 间最小角度等于一个扇形活塞的扇形角。
第一传动齿轮 3a上的传动齿轮定位直齿 51与第二传动齿轮 3b上的传动齿轮定 位直齿 51安装角度相差 180°。 第一转子齿轮 2a与第二转子齿轮 2b上的转子齿轮定 位直齿 50之间的角度因旋转和停转是不断发生变化的。
本发明中的两个转子的动力输出过程为： 在第一转子 l a被控制器解除锁止这一 时刻， 第一转子 l a被第二转子 l b推动旋转， 受推动而转过的角度是一个扇形活塞的 扇形角， 第一转子 l a转动带动固定在其第一转子颈 20a上的第一转子齿轮 2a转动， 第一转子齿轮 2a进而与第一传动齿轮 3a相啮合转动； 当第一转子 l a转过一个扇形 活塞的扇形角度后， 相邻的第一扇形活塞 17a和第二扇形活塞 17b之间形成燃烧室 15， 燃烧室 15内含燃料的压缩空气被点燃或压燃。 第一转子 l a开始做功， 第一转子 l a转动继续带动固定其上的第一转子齿轮 2a转动，第一转子齿轮 2a带动与其啮合的 第一传动齿轮 3a转动， 于是带动与第一传动齿轮 3a固定连接的传动输出轴 8转动， 实现动力输出； 第一转子 l a做功完成后的时刻， 同时也是第二转子 l b被控制器解除 锁止的时刻， 第二转子 l b被第一转子 l a推动向前旋转， 同样受推动而转过的角度是 一个扇形活塞的扇形角度， 第二转子 l b转动带动固定其上的第二转子齿轮 2b转动， 第二转子齿轮 2b进而与第二传动齿轮 3b相啮合旋转， 当第二转子 l b转过一个扇形 活塞的扇形角度后， 相邻的第二扇形活塞 17b和第一扇形活塞 17a之间形成燃烧室 15， 燃烧室 15内含燃料的压縮空气被点燃或压燃。 第二转子 l b幵始做功， 第二转子 l b继续带动固定其上的第二转子齿轮 2b转动， 第二转子齿轮 2b带动与其啮合的第 二传动齿轮 3b转动， 于是带动与第二传动齿轮 3b固定连接的传动输出轴 8转动， 实 现动力输出。 所以， 在本发明中， 第一转子 l a和第二转子 l b的顺序转动所输出的动 力集中在同一根传动输出轴 8上。
如图 2-7所示， 本发明中的传动输出机构中， 还可以在第一转子齿轮 2a与第一 气缸盖 5a之间的中心支撑轴 7上安装一个第一传动间轮 16a; 在第二转子齿轮 2b与 第二气缸盖 5b之间的中心支撑轴 7上安装一个第二传动间轮 16b。第一传动间轮 16a 与第二传动间轮 16b均是完整齿轮， 只在转子齿轮驱动控制器中使用， 分别和第一控 制器齿轮 30a和第二控制器齿轮 30b啮合。
本发明首次真正实现了双转子的动力高可靠性的合成到一个轴上输出世界性难 题， 所采用转子齿轮特定位置缺齿的设计和定位直齿防转子齿轮超越设计（转子齿轮 是完全没有可能滞后的） ， 使转子齿轮和传动齿轮之间的啮合匹配问题完美解决， 实 现了一对一的高精准啮合， 不会发生打齿和错齿现象， 这种高精度啮合同时对转子的 旋转角度有精确定位作用。转子齿轮和传动齿轮包裹在机壳里浸入润滑油中， 磨损和 温度都会减小， 齿轮寿命大幅延长。
如图 3- 1、 图 3-2和图 3-3所示， 本发明中的第一种实施例的转子控制机构包括 相对于缸体 6固定安装的控制器支架 32、第一扇形控制轮 64a、第二扇形控制轮 64b、 第一制动颈 66a、 第二制动颈 66b以及第一往复块 65a、 第二往复块 65b。 控制器支 架 32上安装有若干对滑轮 34。
第一扇形控制轮 64a安装在传动输出轴 8上， 并位于第一传动齿轮 3a外侧， 第 二扇形控制轮 64b 安装在传动输出轴 8上， 并位于第二传动齿轮 3b外侧。 当第一扇 形控制轮 64a和第二扇形控制轮 64b在传动输出轴 8上安装好后，二者中心线之间的 夹角为 180°。
如图 3-6和图 3-7所示， 第一扇形控制轮 64a的结构包括用于安装到传动输出轴 8的第一内圆柱部 71、 设置在该第一内圆柱部 71的扇形部。 扇形部的外圆弧面为顶 起支撑弧面 69 , 扇形部的前侧面 （旋转运动时在前面的侧面） 与顶起支撑弧面 69的 交线为顶起端线 70; 扇形部的一部分从其后侧面 （旋转运动时在后面的侧面） 向外 延伸形成扇形后伸翼 691。 扇形后伸翼 691的顶起支撑弧面 69与其后侧面的交线为 解锁控制线 692。 扇形后伸翼 691的厚度小于扇形部的厚度， 扇形后伸翼 691的一个 表面与扇形部的一个表面位于同一平面，扇形后伸翼 691的另一个表面低于扇形部的 另一个表面， 从而在扇形后伸翼 691的上方形成了后伸翼口 68。 扇形后伸翼 691的 扇形角 N的大小， 以推动往复杆运动过程中与第一扇形控制轮 64a互相不被卡住为 原则， 通常在 30°-50°之间， 这个角度大小因设计需要可以略有变化。 第一扇形控制 轮 64a的扇形角 ZM， 即扇形部的扇形角与扇形后伸翼 691的扇形角 ZN之和， 等于 转子做功角度 ÷ (转子做功角度 + 180° ) x360° - ZL o 其中 ZL是扇形前伸翼的扇形 角， 请见后面的描述。 ZL在 30°左右， 公式中减去 ZL 也是为了在推动往复杆运动 过程中与第一扇形控制轮 64a互相不被卡住， 以这个为原则这个 ZL的大小因设计需 要可以略有变化， 因此第一扇形控制轮 64a的扇形角 ZM的大小也因此略有变化。
例 1、 如果设定转子的扇形活塞的扇形角为 40°， 那么做功角度是 180°—
Figure imgf000015_0001
100°。 传动齿轮周长只有转子齿轮的 280°所对应的周长。 则扇形控制轮 64的扇形角 Μ = 100°÷ ( 100°+ 180° ) χ360° - 30°=98.5714° ο扇形控制轮 64的扇形角 Μ = 98·5714°。
例 2、如果设定转子的扇形活塞扇形角为 45° ,那么做功角度是 180°— 45°χ2= 90°。 传动齿轮周长只有转子齿轮的 270°度。 则扇形控制轮 64 的扇形角 Μ = 90°÷ ( 90°+180° ) χ360° - 30° = 90° ο 所以扇形控制轮 64的扇形角 Μ = 90。
如图 3-8和图 3-9所示， 第一制动颈 66a包括设置于第一转子颈 20a端部并与其 一体的内圆环 661和对称设置在该内圆环 661上的两个制动凸 662， 内圆环 661与制 动凸 662的上、下表面分别位于同一平面内。 内圆环 661的部分外圆周面及邻接的两 个制动凸 662的侧面共同形成了 C形制动槽 76。见图 3-9， 两个制动凸 662的两条对 角线之间的夹角 ZP为 40°， 该夹角 ZP不限于 40°， 在小于 50°情况下均是可行的， 通常其范围可以在 10°-50°之间。 加工制作时， 可以在第一转子颈 20a的伸出第一转 子齿轮 2a的端部上对称地去除一部分圆弧体从而形成两个 C形制动槽 76 ,继而形成 了第一制动颈 66a。
如图 3- 10所示， 第一往复块 65a的结构包括矩形板， 设置在矩形板一端部可与 第一转子颈 20a上的 C形制动槽 76配合工作的 C形制动卡 67、设置在矩形板另一端 部并与其垂直的矩形块 671。 矩形板的上、 下侧面分别设有与控制器支架 32上的滑 轮 34配合工作的导轨 35。在矩形块 671前面下半部设有正时解除顶起台 42， 正时解 除顶起台 42的底面与矩形块 671位于同一平面上，正时解除顶起台 42的顶面低于矩 形块 671的顶面，因而在正时解除顶起台 432的顶面与矩形块 671之间形成了后正时 缺口 43。 正时解除顶起台 42的外侧下面为斜面 421， 正时解除顶起台 42的外侧上面 为顶起弧面 422， 该顶起弧面 422与第一扇形控制轮 64a的顶起支撑弧面 69形状吻 合。斜面 421和顶起弧面 422分别延伸至矩形块 671的外侧面。斜面 421与顶起弧面 422的交线为锁止线 420。 顶起弧面 422与正时解除顶起台 42顶面的交线为解锁线 423。
第二往复块 65b的结构与第一往复块 65a的结构相同， 不再赘述。
第一往复块 65a位于第一转子 2a的第一制动颈 66a和第一扇形控制轮 64a之间， 由第一扇形控制轮 64a控制周期性地往复直线运动， 从而控制第一转子 2a周期性转 动、 停止。
如图 3- 1、 图 3-4和图 3-5所示， 本发明中的第一种实施例的控制机构的控制第 一转子 2a转动、 停止的过程为：
图 3- 1所示为第一转子齿轮 2a锁止的幵始状态， 这时第一转子齿轮 2a上的其中 一个缺齿部分 24正对着第一传动齿轮 3a; 第一扇形控制轮 64a的顶起端线 70由第 一往复块 65a的正时解除顶起台 42的斜面 421滑至锁止线 420。 此时， 第一往复块 65a被推动至最左端， 第一往复块 65a的 C形制动卡 67与第一制动颈 66a的 C形制 动槽 76紧密配合， 锁住第一制动颈 66a不能转动， 进而锁住第一转子齿轮 2a。 然后， 见图 3-4， 第一扇形控制轮 64a的顶起支撑弧面 69沿着正时解除顶起台 42的顶起弧 面 422滑动， 其中第一扇形控制轮 64a中沿其周向有一半顶起支撑弧面 69沿着矩形 块 671上的顶起弧面 422滑动， 另一半顶起支撑弧面 69及扇形后伸翼 691 的顶起支 撑弧面 69沿着正时解除顶起台 42的顶起弧面 422滑动， 在该滑动过程中， 第一往复 块 65a不移动， 始终锁住第一制动颈 66a; 见图 3-5， 当第一扇形控制轮 64a的扇形 后伸翼 691上的解锁控制线 692滑过第一往复块 65a的正时解除顶起台 42上的解锁 线 423时， 锁止解除， 第一往复块 65a向第一扇形控制轮 64a方向移动， 带动其上的 C形制动卡 67脱离第一转子颈 20a的 C形制动槽 76 , 第一转子颈 20a即可以自由转 动， 这时第一往复块 65a的正时解除顶起台 42的顶起弧面 422贴靠在第一扇形控制 轮 64a的内圆柱部 71上。 整个从锁止状态到解除锁止状态完成。 随着第一扇形控制 轮 64a的转动进入下一个锁止一解锁的循环。
第二往复块 65b位于第二转子齿轮 2b的第二制动颈 66b和第二扇形控制轮 64b之间， 由第二扇形控制轮 64b控制周期性地往复直线运动， 从而控制第二转子齿轮 2b周期性转 动、 停止。 第二往复块 65b的动作过程与第一往复块 65a的动作过程相同， 不再贅述。 本 发明中， 在第二转子齿轮 2b被锁止的时间内， 第一转子齿轮 2a转动； 在第一转子齿轮 2a 被锁止的时间内， 第二转子齿轮 2b转动。 这样， 通过传动机构将两个转子上的动力整合 在同一根输出轴 8上匀速顺畅输出。
如图 3- 13所示， 在第一种实施例的控制机构中， 还可以在第一往复块的矩形块 671的侧面设有正时顶起台 79。 该正时顶起台 79的其中一个表面与矩形块 671在同 一平面上， 与该表面相对的另一个表面低于正时顶起台 79低于矩形块 671的相应表 面， 从而在正时顶起台 79与矩形块 671之间形成了前正时缺口 80。
如图 3-14、 图 3-15和图 3-16所示， 在第一种实施例的控制机构中， 第一扇形控制轮 64a上还可以设置扇形前伸翼 84。 该扇形前伸翼 84由第一扇形控制轮 64a的扇形部的一 部分从其后侧面 （旋转运动时在后面的侧面） 向外延伸而形成。 扇形前伸翼 84的前端部 设有导向凸条 78。扇形前伸翼 84与扇形后伸翼 691分布在扇形部的两侧，并且错开布置。 扇形前伸翼 84的厚度小于扇形部的厚度，扇形前伸翼 84的一个表面与扇形部的一个表面 位于同一平面， 扇形前伸翼 84的另一个表面低于扇形部的另一个表面， 从而在扇形前伸 翼 84与扇形部之间形成了前伸翼口 841。扇形前伸翼 84的扇形角 ZL在 30°左右， 以推动 往复杆运动过程中与第一扇形控制轮 64a互相不被卡住为原则， ZL和 相加等于转子 齿轮的做功周长所啮合对应在传动齿轮上同样周长所占的角度。 扇形前伸翼 84与正时顶 起台 79 配合工作。 当第一扇形控制轮 64a上的顶起端线 70到达第一往复块的锁止线 420 时， 扇形前伸翼 84的导向凸条 78同时提前到达正时顶起台 79。 扇形前伸翼 84与正时顶 起台 79的设置可以大大减小第一往复块的锁止线 420及第一扇形控制轮 64a的顶起端线 70的磨损， 有利于延长第一控制机构的使用寿命。
如图 4- 1、 图 4-2和图 4-3所示， 本发明中的第二种实施例的控制机构包括相对 于缸体 6固定安装的控制器支架 321、 第一扇形控制轮 64a、 第二扇形控制轮 64b、 第一制动颈 66a、 第二制动颈 66b以及第一往复框 45a、 第二往复框 45b。 控制器支 架 321上安装有若干对滑轮 34。
该第二种实施例的控制机构结构与第一种实施例的控制机构不的同之处仅在于 两点： 一是控制器支架 321的形状不同， 这不是本发明重点所在， 控制器支架可以是 任意形状的， 只要能使往复框或往复块在其上自由滑动即可。 另一个不同点是， 该实 施例中的往复件是第一往复框 45a、 第二往复框 45b。
如图 4-1所示， 第一往复框 45a的结构包括一个矩形框， 在该矩形框的相对的两 个边中其中一个边上内侧设置正时解除顶起台 42，在另一个边上设有 C形制动卡 67。 正时解除顶起台 42的结构、 功能与第一种实施例的控制机构中一样， 均是在第一扇 形控制轮控制下带动第一往复框往复移动。 C形制动卡 67的结构、 功能与第一种实 施例的控制机构中一样， 用于与第一制动颈 66a的 C 形制动槽配合工作， 使第一转 子 l a制动或运转。
第二往复框 45b的结构与第一往复框 45a相同不再赞述。
该第二种实施例的控制机构结构与第一种实施例的控制机构相同的其他部分不 再赘述。 如图 5- 1、 图 5-2和图 5-3所示， 本发明中的第三种实施例的控制机构与第一种 实施例的控制机构的不同之处仅在于： 增加了一根由控制器支架 29安装的平行于传 动输出轴 8的控制器轴 31和一个安装于控制器轴 31上的控制器齿轮 30。 所述第一 扇形控制轮 64a安装在控制器轴 31上。控制器齿轮 30与第一传动齿轮 3a啮合配合。 所述第一往复块 65a安装在第一转子 2a的第一制动颈 66a和第一扇形控制轮 64a之 间。
增加控制器齿轮 30使控制器支架 322的安装更加方便， 同时可以减小电动机的 轴向尺寸， 使整机的各部分结构布置紧凑， 有利于减小电动机的体积。
该第三种实施例的控制机构与第一种实施例的控制机构相同的其他部分不再赘 述。
如图 5-4所示， 本发明中的第四种实施例的控制机构与第三种实施例的控制机构 的不同之处仅在于： 该实施例中的往复件是第一往复框 45a、 第二往复框 45b。 该第 四种实施例的控制机构结构与第一种、第二种实施例的控制机构相同的其他部分不再 赘述。
如图 6- 1、 图 6-2和图 6-3所示， 本发明中的第五种实施例的控制机构结构， 包 括控制器支架 29安装在缸体 6外并平行于传动输出轴 8的两根控制器齿轮轴 31、 安 装在其中一根控制器齿轮轴 31前部的第一控制齿轮 30a和第一蝴蝶结形控制轮 4a、 安装在另一根控制器齿轮轴 31后部的第二控制齿轮 30b和第一蝴蝶结形控制轮 4b、 由两个蝴蝶结形控制轮控制往复移动的往复框 12、 安装在第一转子颈 20a上的第一 转子控制齿轮 16a、 安装在第二转子颈 20b上的第二转子控制齿轮 16b， 以及相对于 缸体 6固定安装的控制器支架 324， 控制器支架 324上装有若干对滑轮 34。第一控制 齿轮 30a与第一转子控制齿轮 i 6a相啮合； 第二控制齿轮 30b与第二转子控制齿轮
16b相啮合。
如图 6-6和图 6-7所示，本发明中的第五种实施例的控制机构中的往复框的结构， 包括由两条长边和两条宽边组成的矩形框架。在两个宽边上各自设有一个正时解除顶 起台 42和一个后正时缺口 43， 该正时解除顶起台 42的结构与本发明中的第一种实 施例的控制机构中第一往复块 65a的正时解除顶起台 42结构相同， 包括斜面 421、 顶起弧面 422、 解锁线 423。 如图 6- 1 1所示， 还可以设有正时顶起台 79和前正时缺 口 80， 该两个结构与第一往复块 65a 中相同。 两个宽边上的各个结构呈中心对称布 置。
如图 6-9、 图 6- 10和图 6- 14所示， 本发明中的第五种实施例的控制机构中的第 一蝴蝶结形控制轮 4a为一个矩形体 52。 矩形体 52具有两个表面、 两个长面和两个 宽面， 表面上的对角线间的夹角 ZP 1与第一制动颈 66a上的 相同。 矩形体 52的 两个宽面是可以与往复框的正时解除顶起台 42 的顶起弧面 422 吻合的圆弧顶起面 54。 矩形体 52的每个长面由与其中一个圆弧顶起面 54连接的平面 40、 与该平面 40 平滑过渡连接并凹向矩形体 52内的弧面 46， 和连接该弧面 46并和圆弧顶起面 54连 接的斜面 38。 斜面 38和圆弧顶起面 54的交线为顶起端线 50。 斜面 38和弧面 46的 长度之和约等于平面 40的长度。 当第一蝴蝶结形控制轮 4a被锁止时， 往复框的斜面 421和第一蝴蝶结形控制轮 4a斜面 38贴合在一起、 往复框的顶起弧面 422和第一蝴 蝶结形控制轮 4a弧面 46贴合在一起。
矩形体 52从其平面 40向外延伸形成后伸翼 47，后伸翼 47的厚度约为矩形体 52 厚度的 1/3 , 后伸翼 47 的一表面与矩形体 52 的一表面在同一平面内。 该后伸翼 47 与第一扇形控制轮 64a的扇形后伸翼 691的结构相同。 如图 6- 1 1和图 6-12所示， 本 实施中的矩形体 52还可以从其斜面 38向外延伸有前伸翼 58， 前伸翼 58的厚度约为 矩形体 52厚度的 1/3， 前伸翼 58的一表面与矩形体 52的一表面在同一平面内， 前伸 翼 58的另一表面低于矩形体 52的另一表面。 前伸翼 58的前端部设有导向凸条 78。 前伸翼 58和后伸翼 47分别位于矩形体 52长面的两侧， 并错幵布置。 形成于矩形体 52两长面的各个结构呈中心对称。
如图 6- 13所示， 第二蝴蝶结形控制轮 4b与第一蝴蝶结形控制轮 4a的结构相同， 不再赘述。
如图 6- 14， 后伸翼 47 ZN 1等于前伸翼 58 ZL1 , 180°先减去转子做功时长所占角 度，再减去矩形体 52表面上的对角线间的夹角 Z P 1最后所剩余角度除以 2就是 ZN 1 或 Z L1的角度。 03、 04、 05在同一直线上且间隔为蝴蝶结形控制轮的半径， 以 03、 04、 05 为圆心做圆的半径都是蝴蝶结形控制轮的半径， 来画出矩形体 52 内的弧面 46， 弧面 46是与正时解除顶起台 42的顶起弧面 422吻合的。
如图 6-4、图 6- 1和图 6-5所示，往复框 12对两个蝴蝶结形控制轮的控制过程为： 图 6-4所示， 第一蝴蝶结形控制轮 4a的弧面 46、 斜面 38分别与往复框 12其中 一侧的顶起弧面 422、 斜面 421接触配合， 第一蝴蝶结形控制轮 4a与往复框 12互相 锁止：此时，第二蝴蝶结形控制轮 4b的顶起端线 50到达往复框另一侧的锁止线 420， 接着顶起端线 50越过锁止线 420 , 第二蝴蝶结形控制轮 4b的圆弧顶起面 54沿着顶 起弧面 422滑动 （见图 6- 1 ) ， 直到第二蝴蝶结形控制轮 4b的后伸翼 47上的圆弧顶 起面 54滑过往复框 12正时解除顶起台 42顶面， 往复框 12被解锁 （见图 6-5 ) ; 在 往复框 12被解锁的同时， 第一蝴蝶结形控制轮 4a和第二蝴蝶结形控制轮 4b共同旋 转， 共同旋转的角度是一个扇形活塞的角度， 第一蝴蝶结形控制轮 4a的顶起端线 50 沿着往复框 12的斜面 421滑动，推动往复框 12向第一蝴蝶结形控制轮 4a方向移动； 随着第二蝴蝶结形控制轮 4b继续旋转， 当第二蝴蝶结形控制轮 4b另一个顶起端线 50到达往复框 12另一侧的斜面 421 时， 与此同时当第一蝴蝶结形控制轮 4a顶起端 线 50滑至锁止线 420时， 第二蝴蝶结形控制轮 4b的弧面 46、 斜面 38分别与往复框 12的顶起弧面 422、斜面 421接触配合， 第二蝴蝶结形控制轮 4b与往复框 12互相锁 止， 进入下一个锁止一解锁一锁止的循环； 第一蝴蝶结形控制轮 4a沿着往复框 12的 顶起弧面 422滑动， 当第一蝴蝶结形控制轮 4a的后伸翼 47上的圆弧顶起面 54滑过 往复框 12正时解除顶起台 42顶面时， 往复框 12解锁， 在第二蝴蝶结形控制轮 4b 的作用下向第二蝴蝶结形控制轮 4b方向移动， 如此循环往复。
当该实施例中的蝴蝶结形控制轮具有前伸翼 58， 往复框 12 具有正时顶起台 79 时， 前伸翼 58与正时顶起台 79配合工作。 当蝴蝶结形控制轮的顶起端线 50到达往 复框的锁止线 420时， 前伸翼 58的导向凸条 78同时或提前到达正时顶起台 79。 前 伸翼 58和正时顶起台 79 时的作用在于减小顶起端线 50与锁止线 420的磨损， 有利 于延长第一转子控制机构的使用寿命。
如图 7- 1、 图 7-2和图 7-3所示， 本发明中的第六种实施例的转子控制机构结构， 其与第四种实施例的转子控制机构的不同之处仅在于： 往复件是往复块 33， 而非往 复框。 往复块 33的结构包括矩形块和呈中心对称设置在矩形块上的与第四实施例中 相同的两个正时解除顶起台 42、 两个后正时缺口 43。 见图 7-4 , 还可以在矩形块上 设置两个呈中心对称布置的正时顶起台 79、 两个前正时缺口 80。
该第六种实施例的转子控制机构的其他结构及动作过程与第四种实施例的转子 控制机构相同， 不再赘述。
本发明的转子控制机构首次实现了转子的正时控制，精准地控制了转子的旋转时 长和停转时长， 精确做到对转子的按时制动和按时解除锁止。
参见图 1 -8、 图 1 - 10， 第一转子颈 20a与内圆柱缸体 99a连接位置， 内圆柱缸体 99a的圆周上设有密封槽。
参见图 9- 1， 这个密封槽可以采用 0形密封圈 85密封； 参见图 9-2 ， 这个密封 槽也可以采用两个 C形密封条 86密封。 参见图 1 -8、 图 1 - 10和图 1 -1 1， 第一扇形活 塞 17a与内圆柱缸体 99a结合处除外， 平行于轴线环绕第一扇形活塞 17a—周有两道 平行布置的密封槽。密封槽必须设在第一扇形活塞 17a的表面上不能与燃烧室有交叉 连接。
参见图 1 -9、 图 1 - 1 1， 内圆柱缸体 99a在有第一扇形活塞 17a伸出的端面上， 尽 可能靠近内圆柱缸体 99a外圆周处设有环形凹槽 19 , 用以减小纵向密封深度。 第一 扇形活塞 17a上的密封槽与内圆柱缸体 99a端面的密封槽直接相接。 第一扇形活塞 17a上的密封槽通过 L形密封条槽 73与减小纵向密封深度环形凹槽 19相接。参见图 1 -5、 1 -6， 图 9-5， 第一转子 l a的内圆柱缸体 99a和第二转子 l b内圆柱缸体 99b接 触面上的环形减小纵向密封深度凹槽 19对正， 嵌入 0形密封圈 （参见图 9-4 ) ， 使 两个转子的纵向接触面上实现了气密性。
参见图 9-5 , 在所述两个转子 99a， 99b之间的接触的圆周部分及靠近该圆周的端 面部分设有弹簧 89， 在所述弹簧 89与第二转子 99b之间设有 L形密封条 90， 在所述 弹簧 89与第二转子 99b端面之间设有纵向密封片 72， 在两个转子接触的端面之间， 并位于所述纵向密封片 72端部设有 0形密封圈 88。 第一扇形活塞 17a和内圆柱缸体 99a有第一扇形活塞 17a伸出的一端之间， L形 密封条 90嵌入在第一转子上 L形密封条槽 73里， 被弹簧 89压紧。 紧贴 L形密封条 90的 L头设一个小纵向密封片 72，在弹簧 89作用下与减小纵向密封深度环形凹槽 O 形密封环 88紧密接触的实现更好的密封。 L形密封条 90的头部如果过长会在 0形密 封环 88上被支起与另一转子的内圆柱缸体形成一道间隙， 如果过小也会与 0形密封 环 88之间形成间隙。 L形密封条 90的头部采用过小设计， 紧贴头部设一个小纵向密 封片 72， 来弥补与 0形密封环 88之间形成间隙， 从而达到完全密封。 参见图 9- 1、 图 9-2、 图 9-3， 整个密封条沿平行于轴线方向上将第一转子 l a围起来实现密封， 以 保证第一扇形活塞 17a前后进气、 压缩、 做功、 排气四冲程工作室的气密性。 参见图 1 - 10、 图 1 -1 1， 转子上密封槽处加工很细小的孔 98 , 润滑油通过小孔渗出， 为密封 件运行提供润滑， 同时配合密封件起到气密作用。
解决了双转子相互咬合时的纵向缝隙易导致漏气的问题，解决了转子复杂几何面 密封如何实现的问题， 从而彻底解决该发动机的密封问题。
如图 8所示， 本发明的双转子发动机中的中心支撑轴 7是中空的， 具有中心管道 96， 并在安装有转子位置设置喷射孔 97。 两个转子内分别设有孔道 94。 缸体壁上连 通有出油管道 93。 缸体 6和圆盘形前端盖 5a、 后端盖 5b上分别设有多道互相连通的 管道 91。
润滑油被泵入中心支撑轴 7的中心管道 96 , 通过中心支撑轴上的喷射孔 97向转 子内部喷射， 在压力和离心力的作用下在经过转子内的孔道 94， 然后进入转子内腔 室 95， 在腔室内旋转热交换后流向转子扇形活塞 17的与管形缸体 6相接触的面， 在 转子制动时由缸体壁上的出油管道 93流出。 缸体 6和圆盘形前端盖 5a、 后端盖 5b 上分别设置许多管道 91， 管道相通， 管道内填充冷却液， 对发动机进行冷却。
本发明创造性地解决了中心支撑轴内喷油，双转子中空设计，润滑油离心式流动， 缸体出油口设计， 实现了转子内的降温， 同时有缸体上的水冷***相配合， 从而使转 子能够维持在相应的温度范围区间， 使转子的热变形小且机械强度不会降低。 同时润 滑油通过转子密封条上小孔向缸内供油首次解决了缸内润滑问题。
本发明中， 还可以设置转子反转阻挡装置。
如图 10- 1， 一种转子反转阻挡装置的结构， 包括与传动输出轴 8 平行的凸轮轴 104、 摆动从动件 105和弹簧 89。 其中凸轮轴 104上安装有凸轮齿轮 108和盘形凸轮 104 , 凸轮齿轮 108与传动齿轮啮合； 摆动从动件 105包括摆动杆和设置在该摆动杆 一端的与制动颈的制动凸 662 配合工作的 L形翘起的三角头， 三角头具有立面 106 和斜面 107 ; 弹簧 89将三角头压紧到制动凸 662上。
釆用与传动轴 8平行的凸轮轴 104上套装固定凸轮齿轮 108， 凸轮齿轮 108带动 盘形凸轮 107旋转， 与盘形凸轮 1 10相配合， 摆动从动件 105上一头有 L形翘起的三 角头， 三角头与第一制动颈 66a 上的制动凸 662配合， 三角头朝向第一制动颈 66a 旋转方向， 三角头有一个大的斜面 107 , 第一制动颈 66a旋转方向有一立面 106。 当 第一制动颈 66a 上制动凸 662 旋转到与斜面 （或圆弧面） 107接触时， 沿斜面 107 将从动件 105的 L形翘起的三角头压下， 第一制动颈 66a旋转不受影响。
如图 10-2， 当第一制动颈 66a被往复杆制动后， 由凸轮齿轮 108带动旋转， 盘形 凸轮 1 10 的凸起的一头压下从动件 105 另一头， 使三角头翘起， 三角头的立面 106 阻挡制动凸 662， 防止反转。 接着进入阻挡一分离一阻挡的下一轮循环。'弹簧 89作 用于摆动从动件 105上的三角头， 三角头与制动凸 662能紧密配合。本发明主要采用 凸轮和从动件的反转阻挡装置， 上面的实施例只是其中的一种方式。
另一种反转阻档装置是离心甩出销子式转子反转阻档装置。
如图 10-3 , 其中每个所述转子的扇形活塞具有至少一个径向孔， 所述缸体上对 应每个径向孔位置设有一个三角槽，所述转子反转阻挡装置包括放置在所述径向孔内 有销子和弹簧， 其中所述销子头部呈三角形或楔形， 在朝向转子反转方向具有立面， 在朝向缸体的一面具有斜面或圆弧面。
当转子旋转至制动位置时，销子 109在离心力和弹簧弹力共同作用下，迅速甩出， 插在缸体 6上的三角槽 1 1 1上，受燃气膨胀压力推动转子的反向作用力卡住缸体使转 子不能反转。 当转子向前旋转时， 销子的斜面 107在缸体 6压迫下被自动压入转子内 部。 这个防反转装置也可设置到转子颈上。
本发明中在非三缸或者缸数不是三的倍数的情况下要配平衡重。
由于转子齿轮的周长大， 传动齿轮周长小， 因此形成一个 360°比 280°特殊传动 比， 转子做功时长在传动输出轴上输出时， 便会在 360°旋转范围内均匀分两次， 每 次约 120°时长输出， 所以 1 缸， 2 缸的发动机动力输出并不均匀， 需要平衡重加以 平衡，那么在 3缸时能保证每时每刻都有两个缸做功动力输出均匀，所以不需要平衡， 因此说在非三缸或缸数不是三的倍数的情况下要设置平衡重， 以解决做功输出不连 续、 不均匀及振动的问题， 因为本发明传动输出的 360°周期中， 一个缸分两次间隔 输出约 120°左右的动力， 所以要做这样的平衡。
如图 H - l， 在传动输出轴 8上配两个对称布置的平衡重 1 12 ; 或如图 1 1 -2， 在飞 轮 41上配两个对称布置的平衡重 1 12以达到使动力输出达到平衡。
如 12- 1所示， 在进气口 10和排气口 1 1 内各安装有一个废气涡轮增压器 1 14， 两 个废气涡轮增压器 1 14之间连接有连杆。
如图 12- 1， 自然吸气可变压缩比技术。 就是给缸体设定一个最大的压缩比， 如 使用柴油的压缩比是 18比 1 ，以柴油压缩比为基准，设定发动机压缩比是是 18比 1， 此时发动机使用柴油没有任何问题。缸体 6内的两个转子扇形活塞 17a和 1 7b靠在一 起形成燃烧室 1 5时， 缸体 6与两个转子 l a和 l b之间， 形成了最大压缩室， 具有总 进气量， 最大压缩比是 18比 1。 在缸体 6的进气压缩区域缸体壁的中段开孔， 孔上 安装进气泄压阀 1 13。 在缸体壁上通过幵启进气泄压阀， 如进气后放掉多余的空气， 那么这时发动机的压缩比将减小， 可以是 10比 1， 也就是压缩比从 18比 1减小到 10 比 1 , 可以使用汽油为动力了。 压缩比的大小可以通过进气泄压阀 1 13幵启大小来调 节， 也可以在缸体壁上可以设置多个进气泄压阀 1 13， 用到哪个压缩值， 就幵启哪个 进气泄压阀。通过开启进气泄压阀的大小或进气泄压阀的多少， 形成压缩比也可以是 多个。
当带进气增压技术的方案， 如使用废气涡轮增压器 1 14 , 采用进气增压， 使总进 气量远大于所要采用的压缩比值气压，由进气泄压阀 1 13将超过所需气压的多余的空 气排出， 这种方案发动机通常状况下设定的压缩比可以是任何一个压缩比， 如 18比 1， 或 10比 1'等。 进气增压方式也可采用机械增压， 或两种增压方式合并使用。
如 12-2所示的智能可变压缩比， 可以由电子处理器综合采集各类信息， 经处理 后得出一个最佳方案例如电子处理器， 用于接收并处理车、 船或机械运行工况信息， 发动机工况信息， 燃料信息， 进气或进气增压信息， 缸体内压缩比信息， 进而选定燃 料， 选定压缩比， 选定点火方式， 选定增压器工作方式， 然后再传达到执行单元， 使 可变压缩比效果最优。
本发明的双转子发动机能够灵活采用多种燃料，可以同时釆用点燃和压燃工作方 式， 首次做到大扭距和大功率之间的灵活切换， 有效地提高发动机的工作效率， 并减 少燃料消耗。
如图 13所示， 为发动机的转子控制***和传动***加个外壳 1 15 , 内充润滑油， 为转子控制机构和传动机构润滑和降温。
如图 14所示本发明双转子发动机增加一个进气口 10和一排气口 1 1而形成压缩 机、 泵机的实施例： 缸体、 控制机构、 传动机构与前述双转子发动机相同， 只是同一 个缸体有两个进气口 10和两排气口 1 1 , 两个进气口 10和两排气口 1 1互相间隔并呈 中心对称布置，双转子将缸体切割成两个吸气室和两个压缩室，只有吸、压两个行程。 工业实用性
综上所述， 本发明实现了进气、 压缩、 做功、 排气发动机工作四个冲程并行工作， 效 率提升四倍， 发动机体积小、 重量轻、 动力和功率强， 为混合动力应用中的发动机和电池 腾出的很大重量和空间。 模块化程度高， 装配灵活能有效减少生产设备投入。 本发明通过 双转子、 转子控制机构、 传动机构的相互协同作用， 本发明的双转子发动机解决了双转子 工作状态控制， 特别是实现了转子的正时控制， 将双转子的动力高可靠性地整合到一个传 动输出轴上匀速顺畅地输出。 使这种发动机能够真正运转， 并有了实用的价值。
通过以上较佳具体实施例的详述， 是希望能更加清楚描述本发明的特征与精神， 而并 非以上述所披露的较佳具体实施例来对本发明的范围加以限制。 相反地， 其目的是希望能 于本发明的保护范围内涵盖各种改变及具有等同性的安排。 因此， 本发明的保护范围应该 根据上述的说明作最宽广的解释， 以致使其涵盖所有可能的改变以及具有等同性的安排。
