I have no idea how to project my 3d grill into my surface model. I was trying to use curve project tool or wrap tool and it didn't work. Is it right tools to do it ? I've attached the photo of my model
You could also use your sketch to Split the faces of the base surface, and then delete the faces you don't want. It gets a little confusing because the base surface is made up of so many surfaces, but give it a try and see what method you like best.

I'm not 100% sure of what type of feature you are trying to add, but it looks like you want a mesh opening for air intake.
Your Szkic1 is no good. You'll want to repair it, or delete 99% of it as I have. There are a bunch of extra lines and arcs in it which prevent it from being useful. There are also hundreds of lines in it, and that is rather slow and difficult to work with.
Make it smaller, experiment to see what works, then make it more complex if you need to.

The Indent command might help, but I can't say for sure from the pictures.
Depending on the desired outcome, the grill would usually be a separate component that fits into the body panel.
If this is for a rendering, it might be easiest to create the grill with a texture or opacity filter.
If your base scan data is symmetrical, I'd consider cutting it in half. Then you can work on half of it, and mirror everything at the end.
I think this is what you are after:
