首先，我们知道，发动机是通过燃油和空气的燃烧来提供动力的。而燃油的燃烧，是在发动机气缸内完成的。那么，燃油是如何进入到气缸的呢
是：喷！燃油是通过喷油嘴喷射进入气缸的。而电喷和直喷都是发动机的供油方式。电喷可以分为单点电喷和多点电喷，其中单点电喷由于技术落后等问题已经几乎看不到了，而直喷又叫做缸内直喷。
一、什么是多点直喷呢
多点电喷就是汽油发动机在工作过程中，在进气歧管内由控制程序按照特定时序发出控制指令，通过电子喷油器完成喷射。其中每一个喷油嘴上，一个喷油孔，它是将燃油直接喷入各气缸的进气岐管，然后进入相应的燃烧。
简单来说，就是相比以前的单点直喷可以更大范围的对气缸进行“塞气”。
二、什么是缸内直喷呢
这个就比较好理解，缸内直喷就是将燃油喷嘴安装于气缸内，然后将燃油简单粗暴的直接喷入气缸内与进气混合的技术。
相比于多点直喷
三、二者有各有什么优缺点呢
多点直喷比较老，优点自然显而易见，就是技术比较成熟，经用耐造，而且维修保养都相对比较便宜，对于油品的要求也不高
当然它相比缸内直喷的缺点也十分明显，就是油耗相对比较高，动力相对比较肉。
而缸内直喷则是比较新的技术，所以它的优缺点则是和前者几乎倒置的。优点相比自然就是燃油效率更高更充分，且排放和油耗相比也更为少与低。
缺点也是类似，和前者倒置，即制造成本更高，维修保养也更贵，所以相比之下更多的会装置在比较贵的车型身上。此外，由于结构问题，其积碳也会相比更多。
缸内直喷的优势是压力高，雾化好，燃油喷射量，所以动力输出好
CRIN2 标准3型6孔式喷油器,喷油器由喷油器体、孔式喷油嘴总成、液压伺服系统以及电磁阀总成等组成。喷油器上有一组十位数的编码,为Bosch的订货号,用于购买配件时使用。
