Description

涡流增压进气装置 技术领域
本发明涉及汽车发动机制造领域的一种运用内燃机真空吸力进气转变成涡流增压进气来助燃的设备，一种涡流增压进气装置。
背景技术
涡轮增压技术是目前汽车生产中的常用技术，涡轮增压的发动机是利用发动机排气推动排气风扇涡轮联动进气风扇涡轮增压进气或是曲轴带动驱动盘利用皮带拉动风扇涡轮而产生增压进气帮助燃油在燃烧室燃烧，100年前至今常见风扇涡轮增压器的价格昂贵又不安全(因为加压的空气温度高且会有排气阻力产生)，进入燃烧室的空气温度是高于一般自然进气发动机的进气温度且是质量低的空气，进气热源温度高危险、整体构造非常复杂且涡轮机非常容易损坏，更换维修费用高、更容易因为积碳而耗油并增加了排气污染；还有一个长久以来无法改变的缺点，就是需要发动机达到一定的转速才能驱动涡轮增压器作动。
现今世界各大制造商为了节能减排、增加动力，致力研发新的发动机来突破瓶颈，HCCI(均质压燃)发动机能达到这个目标，但还需要克服最重要的两个因素(燃料、空气)。
发明内容
本发明提出一种涡流增压进气装置，配合安装在发动机引擎室内，解决了现有任何发动机或内燃机的热效率低、以及因燃烧不完全造成的怠速至低速动力不足的问题。
本发明是通过以下技术方案实现：
一种涡流增压进气装置，它安装在发动机引擎室内，包括空气催化罐、涡流增压器以及涡流喷嘴；所述空气催化罐的出气口通过连接管与涡流增压器的进气口连接，涡流增压器的出气口通过连接管与涡流喷嘴连接，涡流喷嘴置于发动机进气管道内；其特征在于，它还包括涡流空滤罩；所述涡流空气罩通过连接管连接空气催化罐的进气口；冷热空气通过发动机进气的真空负压吸入涡流空滤罩至空气催化罐内，催化罐将空气转换成湿冷空气，经涡流增压器增压后，由涡流喷嘴将湿冷的增压空气导入发动机内帮助燃料燃烧。
利用发动机真空吸力经过涡流喷嘴，使容积改变形成更大的负压(真空)，经过连接管使涡流增压器里的空气作动，使从催化罐来的优质空气再次加速流速，达到空气再增压的效果，而因为在增压器里的空气流速加快，所以使经过连接管连接的空气催化罐里面的空气作动加强，使原本就有增压的效果更为加强，经过连接管使涡流空气罩里的空气作动，再一次增压；同时通过涡流空气罩过滤从发动机引擎室内空气，使得空气更干净；因为空气催化罐一直处于发动机室内，所以空气催化罐里面的空气比外面进入的空气热，进入空气催化罐冷空气与空气催化罐里的热空气混合，造成湿冷(雾气)空气的产生；从而实现在发动机任何转速下，将发动机引擎室内干热的空气转换成更干净、湿冷的增压空气来帮助发动机燃烧室的燃油完全燃烧，提高了发动机燃烧效率，发动机低转速时燃烧更完全了，能增加发动机怠速至低速(转速2000rpm以下)扭力50％～80％，提高节能减排效果；因为燃油燃烧时的空气质量更好了，发动机的性能提高了25％～35％。
对上述技术方案作进一步的改进和细化，所述涡流空滤罩包括上罩、下罩、空气滤清器；上罩为圆柱状，下罩为漏斗状，上罩一端开口，且与下罩的斗部卡合，形成一个设置空气滤清器的空腔，上罩另一端设置有若干通孔，通孔呈现放 射性分布在上罩圆周外侧，形成两个同心圆；空气滤清器设置在空腔内，空气滤清器的出口与下罩的斗嘴连接；下罩的斗嘴通过连接管连接空气催化罐的进气口。
空气从通孔吸入，通过空气滤清器，再由下罩斗嘴流出。通孔的分布、配合下盖斗嘴位置设计，在发动机真空吸力下，空气有边侧向中间聚拢，形成涡流，使得吸入的空气从而得到更好的优化，更乾净、更低温，使得整体装置得到更好的性能提升(提升40％左右)，能够持续且稳定的真空增压空气。因为上罩、下罩的保护，让置于其中的空气滤清器在使用上更加延长更换时间及性能效果。
对上述技术方案作进一步的改进和细化，所述通孔共40个；满足进气需求同时效果最佳。
对上述技术方案作进一步的改进和细化，所述的涡流增压器包括筒体，筒体一端为进气口，另一端为出气口；进气口包括一大一小两个圆筒，大圆筒同心套设在小圆筒上，大圆筒与小圆筒之间通过均匀分布的连接筋连接，且小圆筒一端向筒体内部延伸成锅盖形状，且与筒体之间留有间隙，出气口为圆弧口。
设计构造原理相似于”飞机发动机”内部结构原理，使来自涡流喷嘴内部流动的真空气体一次进气来带动涡流增压器外部的气体二次进气，由进气口入至涡流增压器内部，基于康达效应原理，达到增压的目的。
对上述技术方案作进一步的改进和细化，所述空气催化罐包括圆柱型罐体，罐体顶部开口且在其上设置有封盖，封盖上设有进气口和出气口，进气口设置在封盖的中心位置，为一竖直设置的管，直管上端穿过封盖伸出，下端伸入罐体底部，且在其上至下设置有若干由绕管螺旋设置的挡板构成的烟囱盖子，烟囱盖子上设置有若干小孔。
透过涡流增压器的强劲吸力使空气催化罐的出气口产生抽真空的吸力效果， 让较冷的空气由催化罐的进气口进入到罐子底部，再由三个烟囱盖子上的小孔，由下往上、从左至右、从右至左流动，最后和罐子里的热空气混合，造成湿冷(雾气)空气的产生，混合更均匀，效果更好。
对上述技术方案作进一步的改进和细化，所述涡流喷嘴包括锥形喷嘴与螺纹连接管；螺纹连接管一端与锥形喷嘴螺纹连接，另一端通过连接管与涡流增压器的出气口连接。
对上述技术方案作进一步的改进和细化，其特征在于，所述涡流喷嘴呈子弹状，涡流喷嘴内设置有流道，流道由若干不同直径的圆柱体通道依次串连形成；主要作用是加速真空压力差的形成、提高稳定的空气流速、增加进气压力。
对上述技术方案作进一步的改进和细化，所述连接管为软管。
本发明的优点是，设计合理，构思巧妙，性价比超高，利用发动机自然产生的负压(真空)吸力作用而产生涡流增压进气(龙卷风效应原理－低压与高压的压力差使空气形成强对流作用)，安全；有效提高了进入发动机燃烧室燃烧的空气质量后，燃烧更完全，进而产生如下有益效果：
1、降低发动机排污80％以上的发生，动力增加25％～35％，弥补因发动机先天设计上的缺陷。
2、动力增加，相对时间内油门踩踏深度减轻，而达到油耗降低的发生；另外当遇踩煞车或放开油门踏板时，因助燃还是继续产生，且会让车辆滑行距离更长，实现达到油耗降低15％～25％的效果。
3、发动机运转顺畅，行驶中发动机更安静，震动也更少，发动机噪音降低60％以上，发动机使用寿命更长。
4、更容易使HCCI(均质压燃)发动机达到(均质压燃)效果。现今世界各大制 造商为了节能减排、增加动力，致力研发新的发动机来突破瓶颈，HCCI(均质压燃)发动机能达到这个目标，但还需要克服最重要的两个因素(燃料、空气)；本技术发明，能更进化(优化)进气空气的质量(湿冷)、密度(大于大气压力)、流速(大于自然进气速度)，使该型式的发动机更容易的达到(均质压燃)效果。
