[EN] The present research project aims to carry out a detailed study of a new internal combustion engine (ICE) model, that is able to avoid completely nitrogen oxides emissions, which are produced during the combustion process. This study will obtain realistic results using one-dimensional simulations using the non-commercial software VEMOD devoloped by the Centro de Motores T´ermicos (CMT) . This new concept is the result of both the combination of highly known elements, already used in current ICE, and the incorporation and use of new elements (solid ion transport membranes), arising as a result of technological advances in multiple areas of engineering, specifically in the field of Chemical Technology. The engine, which is aimed to be designed, maintains a very similar structure when it is compared with other real and current engines. It tries to combine some of the positive aspects already known, and its behavior is similar to the current cycles used in power generation for self-propelled vehicles. The purpose of this research project is to focus on an the adaptation of specific current and real engines dedicated to automotive propulsion. The final result of this project can be simplified as the design of the motor itself, and the coupled elements, to obtain a target power on a shaft while maintaining the minimum possible consumption; These results will be compared with those of the originally modified engine to evaluate them and their actual viability. The combination of knowledge of different areas has been possible due to cooperation of the following research centers, located at the Universitat Polit`ecnica de Val`encia: this project was developed at the Centro de Motores T´ermicos (CMT), and technology advances carried out by the Instituto de Tecnolog´ıa Qu´ımica (ITQ).
