Uma breve análise sobre motores diesel dois tempos

Abstract

On board the various Merchant ships around the world, if we want to learn how a ship really works, we are guided to understand a lot about Diesel engines. Talking about Diesel engines, we could say there is the two stroke diesel engine, and there is the four stroke diesel engine, which are explained more precisely in the next pages of this final paper. We’ll learn something about the history of the very first Diesel engines, how they were created and how come they became so necessary. We are also learning about some mechanisms and processes used in this engines, how important parts of the engine work and how their cicle is explained. The Marine Diesel Oil, which is used by this kind of engines, it must be injected correctly in order to unleash the power the ship needs. We also have to take care of some exhaust gases that can be harmful to the environment. At last, we are explaining something about the common rail system that injects fuel into the combustion chamber at the correct pressure and temperature. It also commands all the parameters of the engine using sensors and actuators.
