Proceso de marinización de un motor Mitsubishi S4Q para su uso como propulsor de una embarcación

Con el presente trabajo de final de grado, se analiza y desarrolla el proceso de marinización de un motor que llega a fábrica como un motor terrestre y sustituye varias piezas del motor pasa a ser un motor marino. para este propósito, varias piezas originales del motor terrestre s4q son sustituidas, y con el fin de minimizar el coste económico total de la modificación se realiza un análisis teórico para poder adaptarlo a las embarcaciones y tratando de modificar lo mínimo posible la bancada de la embarcación. además de lo explicado anteriormente, también se realizará un proceso de mantenimiento del motor que puede ser llevado a cabo por el propio armador y que se ajuste a la normativa actual. The main aim of the former piece of research is to analyze and develop the process marinized a Mitsubishi S4Qengine for use as a ship propeller. Thereby, the engine under study is a Mitsubishi S4Q in-line 4-cylinder with atmospheric aspiration and an intermittent power of 59 HP (43,4 kW). For its manipulation it is necessarily know perfectly its operation and manufacturing characteristics.The use of the endothermic engine, both the compression ignition, diesel, and the spark ignition, for the propulsion of boats and ships has been carried out for many years.It is therefore of interest to make a historical compilation of the technological evolution of this machine in a summarized and schematic way that explains the reasons for the conditions and characteristics of current engines such as the one under study.However, there is a research study behind that analyzes and proposes design improvements of many elements such as sea water pumps, control panels, hangers, etc. This study seeks to capture these two sources of knowledge, empirical and research, which currently governs the process of construction of new engines.
