Can Buick Excelle 1.8 replace the porous nozzle to save fuel?

I can't. More fuel injection holes are not fuel efficient, and controlling the optimal speed is the most fuel efficient. When driving, the number of revolutions of the automobile engine is about 2200-2500. Buick Excelle is an entry-level family car launched by SAIC-GM Buick, and the prototype is a global mid-level car newly developed by GM.
