The process of complete combustion of diesel engine is influenced by many factors. Several parameters such as flow system, injection system, shape of combustion chamber and fuel property affect the complete combustion state of diesel engine. Especially, the fuel-air mixture of diesel engine combustion has predominant effects on engine performance and pollutant emission. For the experiment, three kinds of the combustion chamber were designed and manufactured to consider the cavity shape and the air flow. In addition we changed four-cycles diesel engine into two-cycles visualization of diesel engine. And then we analyzed the effect of shape of combustion chamber type, scavenging pressure(106.4kPa, 111.5kPa) and scavenging temperature(2p℃) on combustion flame in order to find optimal combustion chamber condition for better combustion and better performance. As a result the combustion process of the cylindrical type in the state of scavenging pressure of 111.5kPa and scavenging temperature of 20℃ showed the best effects.

Due to the fast spread and technical development of the computer, the computer application has been deeply used in our society and has been managed the typical method for managing information. Therefore, teachers try to find an efficient method to manage their, classes and students by using computer. Most class systems implemented today in ordinary schools are not suitable for special schools for mentally diabled students, in terms of feasible management and administration of classes and students. This paper aims to design and implement a special class management system that can exploits the characteristics and actual conditions of special schools.
