背景技术
此前，发明人提出了一种申请号为200780030483.8、 发明名称为组合式风气发动机及机动车。该发明的主要特点是分别设置独立结构的压缩气体发动机和风阻发动机，可根据压缩气体的流速高、相对集中，而风阻气流的流速低、相对分散的特点，分别有针对性地对叶轮进行优化设计，以提高能量使用效率。采用该组合式风气发动机的机动车既采用压缩气体作为主动力，又直接采用动力机械在行驶过程中所遇到的风阻气流作为辅助动力，还可以使压缩气体和风阻气流能够更好地配合使用。
但是，这种新型的以压缩气体作为动力的新能源汽车仍还有大量的技术工作要做。
 技术问题
本申请的目的是进一步提高压缩气体发动机的动力性能。

进一步地，所述叶轮室上对称开设有三个排气口，所述各排气口之间装设的所述至少两排喷气嘴的未端之间的间距小于所述相邻叶齿之间的距离，使得各排气口之间的所述至少两排喷气嘴喷出的压缩气体能够同时作用于同一叶齿上。
进一步地，在每一排气口之前的所述叶轮室上装设两排喷气嘴。
进一步地，在各排气口之间的所述叶轮室的内表面上开设有与叶轮的转动方向相一致的喷气导入槽，所述至少两排喷气嘴的喷气出口装设在所述喷气导入槽内。

进一步地，所述喷气导入槽与相邻的排气槽之间的最近距离大于相邻叶齿之间的距离。
 有益效果
采用上述技术方案，其有益的技术效果在于：
通过在每一排气口之前，沿叶轮室的转动周面上装设至少两排喷气嘴，可根据发动机的动力性能需要，灵活加大喷气量。
通过设置至少两排喷气嘴的喷气出口之间的距离小于叶轮上相邻叶齿之间的距离，可以根据需要灵活设置能够同时作用于同一叶齿上的喷嘴数量和喷嘴的直径。一是在同等喷气量的情况下，可以针对叶齿的叶面形状，对喷嘴的数量、喷嘴的直径、喷射的角度和布局进行优化设计，提高压缩气体的喷射效率；二是在同等喷气量的情况下，避免了采用大孔径集中喷射时，因喷嘴的工作负荷过重，容易导致的喷嘴结冰甚至因结冰而堵塞喷射气流的问题。通过分散的喷嘴设置，减轻了各喷嘴的工作负荷，大幅减少甚至消除喷嘴结冰甚至因结冰而堵塞喷射气流的问题。
通过在叶轮室上对称开设三个排气口，并在各排气口之间设置喷气嘴，优化了发动机的动态平衡能力，有利于提高发动机的转速。
通过设置喷气导入槽，喷气导入槽的长度至少大于两个相邻叶齿间距离，可以通过一个进气口同时对两个以上的叶齿作功，大大提高了发动机的动力性能。

 本发明的实施方式
下面结合附图与具体实施方式对本发明作进一步详细的描述：
实施例一
一种压缩气体发动机，如图1和图2所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。其中：
在叶轮室5的内表面上开设有与叶轮6的转动方向相一致的喷气导入槽4，叶轮室5上对称装设有三排喷气嘴（1、2、3），每一排喷气嘴与叶轮6的转轴轴线平行设置，每一排喷气嘴的数量可以是一个或多个，根据叶轮6的宽度及喷气嘴的喷气孔大小和所需的喷气量而灵活设置，相邻的各排喷气嘴之间错位设置，用于优化叶齿8的受力面，三排喷气嘴（1、2、3）的喷气出口都装设在喷气导入槽4内，在叶轮室5上开设有一个排气口9，在叶轮室5的内表面上开设有与叶轮6的转轴轴线平行的排气槽10，排气槽10的宽度与叶轮6的宽度基本相一致，排气槽10与排气口9相通。
叶轮6上等间隔开设有多个叶齿8，叶轮6的前后两侧设置有侧板11，由相邻叶齿8、相邻叶齿之间的前后侧板11以及相邻叶齿之间对应的叶轮室5的部分内表面构成能够存储喷入的压缩气体的保压室7。叶轮6与叶轮6的前后两侧侧板11可以是整体加工而成，也可以是分别加工后组装而成。
为了使进入喷气导入槽4的压缩气体能够同时作用于多个叶齿8上，产生更大的推力，喷气导入槽4的长度远远大于相邻叶齿之间的距离（L1）。另外，为了防止漏气，避免刚喷入的气体直接从排气槽10排出，喷气导入槽4与排气槽10之间的最近距离大于相邻叶齿之间的距离（L1）。
工作时，一方面，通过对称设置的三排喷气嘴（1、2、3）喷出的压缩气体推动叶轮6运转；另一方面，当叶轮6转动时，每一个保压室7依次转动经过第一排喷气嘴1、第二排喷气嘴2和第三排喷气嘴3，保压室7接收并保存三排喷气嘴（1、2、3）喷入的压缩气体。当经过三次保压、增压后的保压室7在经过排气口9时，保压室7内的压缩气体二次作功，通过排气口9迅速喷射释放，通过反作用力再一次推动叶轮6运转。
实施例二
另一种压缩气体发动机，如图3所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例一的不同之处在于：设置了九排喷气嘴，其中每三排喷气嘴为一组，构成对称设置的三组喷气嘴（1、2、3），从而可以加大喷气量，提高动力性能，本实施例的其它结构同实施例一。
实施例三
又一种压缩气体发动机，如图4所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例一的不同之处在于：设置了六排喷气嘴，其中每两排喷气嘴为一组，构成对称设置的三组喷气嘴（1、2、3）。特别的设计在于：构成每一组喷气嘴的两排喷气嘴的喷气出口之间的间距（L2)小于叶轮上设置的相邻叶齿之间的距离（L1），使得每组的两排喷气嘴喷出的压缩气体能够同时作用于相同的叶齿上，此结构能够大大提高对单个叶齿的作功能力。本实施例的其它结构同实施例一。
实施例四
又一种压缩气体发动机，如图5所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例三的不同之处在于：设置了十二排喷气嘴，其中每四排喷气嘴为一组，构成对称设置的三组喷气嘴（1、2、3）。构成每一组喷气嘴的相邻两排喷气嘴的喷气出口之间的距离（L2)小于叶轮上设置的相邻叶齿之间的距离（L1），不但使相邻的两排喷气嘴喷出的压缩气体能够同时作用于相同的叶齿上，而且使进入该组喷气嘴喷射区域的叶齿被四排喷气嘴持续地喷气作功。本实施例的其它结构同实施例三。
实施例五
又一种压缩气体发动机，如图6所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例一的不同之处在于：在叶轮室5上对称开设有三个排气口9、三个排气槽10和三个喷气导入槽4，各排气口9分别与对应的排气槽10相通，各排气口9之间的叶轮室5的内表面上开设有与叶轮6的转动方向相一致的喷气导入槽4，三排喷气嘴（1、2、3）对称分设于各排气口9之间，每一排喷气嘴的喷气出口都装设在各自对应的喷气导入槽4内，本实施例的其它结构同实施例一。
本实施例通过对称设置三排喷气嘴和对称设置三个排气口9，进一步提高了喷气嘴喷入压缩气体时叶轮的受力平衡问题，又解决了保压室7内的压缩气体二次作功时叶轮的受力平衡问题。
实施例六
又一种压缩气体发动机，如图7所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例五的不同之处在于：设置了九排喷气嘴，其中每三排喷气嘴为一组，构成对称设置的三组喷气嘴（1、2、3），三组喷气嘴（1、2、3）对称分设于各排气口9之间，从而可以加大喷气量，提高动力性能，本实施例的其它结构同实施例一。
实施例七
又一种压缩气体发动机，如图8所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例五的不同之处在于：设置了六排喷气嘴，其中每两排喷气嘴为一组，构成对称设置的三组喷气嘴（1、2、3）。特别的设计在于：构成每一组喷气嘴的两排喷气嘴的喷气出口之间的间距（L2)小于叶轮上设置的相邻叶齿之间的距离（L1），使得每组的两排喷气嘴喷出的压缩气体能够同时作用于相同的叶齿上，三组喷气嘴（1、2、3）对称分设于各排气口9之间。本实施例的其它结构同实施例一。
本实施例通过在叶轮室上对称开设三个排气口，各排气口之间设置两排喷气嘴的喷气出口之间的距离小于叶轮上相邻叶齿之间的距离，可以根据需要灵活设置能够同时作用于相同叶齿上的喷嘴数量和喷嘴的直径，既可以灵活加大喷气量，又可以实现在同等喷气量的情况下（喷嘴直径小、但喷嘴数量多。），提高压缩气体发动机的动力性能（喷嘴直径越小，喷力越大，射程越远。）。这种三进三排的工作方式，优化了发动机的动态平衡能力，有利于提高发动机的转速。
实施例八
又一种压缩气体发动机，如图9所示，包括叶轮室5、通过转轴装设于叶轮室5内的叶轮6。 本实施例与实施例七的不同之处在于：设置了十二排喷气嘴，其中每四排喷气嘴为一组，构成对称设置的三组喷气嘴（1、2、3）。构成每一组喷气嘴的相邻两排喷气嘴的喷气出口之间的距离（L2)小于叶轮上设置的相邻叶齿之间的距离（L1），不但使相邻的两排喷气嘴喷出的压缩气体能够同时作用于相同的叶齿上，而且使进入该组喷气嘴喷射区域的叶齿被四排喷气嘴持续地喷气作功。本实施例的其它结构同实施例七，三组喷气嘴（1、2、3）对称分设于各排气口9之间。采用本实施例，能进一步加大喷气量，提高动力性能。
以上内容是结合具体的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
