How to add product model to description?

Hello
I want to add product model in product description to make a sentence like this.

We sell the best {product_model }. By adding this place holder, it should insert product model automatically as i plan to do it for thousands of product.

What code do i need to twist?
Thanks

Not just code, you need to add a parser of particular tag format. OpenCart doesn't have any parsers in the code by default.

I paid someone to write small xml extension. It's working perfect now.
