1967年，德国Bosch公司研制成D型电子控制汽油喷射系统，随后又开发了L型电子控制喷射系统，后来这些技术
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured

空燃比的高精度控制。因为汽油是在一定的压力下喷出的，燃油雾化质量好，且喷油量是精确地控制的，混合气的空燃比为最佳值且各缸分配较均匀，下坡时又可以完全不喷油，发动机只对空气进行压缩，所以可以降低燃油消耗量。装用EFI后比传统化油器省油5～15％。
5、减少排气污染。因为EFI装置可以分别控制汽油量与空气量，控制精度很高，能始终保持所需的最佳空燃比。该装置与三元催化剂配合使用时可以使废气中的CO、HC、NOx控制在最低
