Engine System

The heat engines are using as a power source for transportation or co-generation system. The engines will continue to be used in the future. However, the heat source of the engine is combustion! The combustion has various problems such as emission of air pollutants and depletion of fossil fuels. On the other hand, the combustion has big advantages due to the high energy density. It is difficult to find out the high-density energy source instead of combustion. As mentioned above, I will explain from the basic point of thermodynamics and combustion dynamics in this lecture what is important for the high efficiency engine and why combustion phenomena in the engine. Furthermore, I will discuss ways to control emission, pollution and reduce energy loss. In the latter half, I will also explain the various engine systems such as direct injection gasoline engine, hybrid engine, combined cycle, and will discuss the thermal efficiency from the macroscopic point. I will invite a specialist in the lecture 13th.

The engine system associates with all mechanical engineering areas. I am one of a specialist of combustion dynamics and also a mechanical engineer. So I will explain the engine system based on the combustion phenomena inside the engine. From the second law of thermodynamics, the combustion process in the gas cycle is very important issues. However, as represented by the theoretical cycle of gasoline engines, it is impossible that to do constant combustion in the actual machine. The purpose of this lecture is to explain contradictions between the theories and actual engines from combustion phenomena, and will discuss the present and future engines.

1. Students can understand the basic structure of heat engine such as spark ignition engine, compression ignition engine, gas turbine engine.
2. Students can understand the characteristics of various thermal cycles and can explain the characteristics of throttling cycle and supercharged cycle.
3. Students explain the fundamentals of combustion phenomena in heat engines, for example, it is possible to explain fundamental things about quenching distance, burning velocity, flammability limits, turbulent flame structure, etc.
4. Students can understand the influence of the characteristics of the combustion phenomenon on the basic characteristics of the heat engine. Based on the above three items, students can be integrated to explain the characteristics of the heat engine.
5. Based on the thermodynamics and the chemical reaction energy, students can explain application and development of hybrid systems with other energy sources such as fuel cell.
