The prefix "meta" in "metamaterial" is the Greek word, which means beyond the material. Therefore, metamaterials have properties beyond natural materials. The properties of these materials are not affected by the material from which they are composed, however, their properties depend on their structure. This particular structure in metamaterials is produced by the repetition of similar components or arrays called cells. Therefore, metamaterials have a very complex structure. As a result, the high ability of additive manufacturing to fabricate complex structures has drawn attention to this technology. There are different types of metamaterials that are generally divided into four groups, each of which is widely used in various fields, including defense, automotive, aerospace, and medicine. The purpose of compiling this article is to get acquainted with the types of metamaterials, different cells, applications, and methods of manufacturing these materials comprehensively and categorized. This article also specifically examines the application of metamaterials in the automotive industry.

This article describes the advanced design of the car engine at IPCO. Product development models including model V, gateway and network are described first. In the following, in order to introducing engine production to readers, some of the literature and subsystems of the engine are briefly presented. There are also different levels of engine development programs, either low, medium, high, or completely new products. Depending on the level of development, the development of the engine takes 4 to 48 months. Members of the development team and components influencing engine development are also introduced. By these premises, a product development model from the beginning, the conceptual development phase, to mass production with its details is described. At the end, by combining V and Gateway models, the details of the IPCO product development model are outlined. In fact, the result of this article is to systematize the engine development process in Iran and the Iran Khodro complex. As such structure has not existed in Iran so far, IPCO, as a domestic innovative engineering company in the design and production of engines, has described the model used by researchers and industry leaders in field.
