In this study, we investigated the effects of EGR rate and engine load on the emission characteristics in a 4-cylinder common rail direct injection diesel engine fueled with canola oil biodiesel (BD) blended fuel. The biodiesel blend fuel, BD20 (20 vol.% biodiesel and 80 vol.% ULSD blend) was used at an engine speed of 1,500rpm. The experimental results showed that with the increasing of EGR rate, the combustion pressure and rate of heat release (ROHR) of three test fuels were decreased, and the ignition delay was extended, the carbon monoxide (CO) and particulate matter (PM) emissions increased slightly, but the nitrogen oxide (NOx) emission decreased clearly. On the other hand, with the increasing of engine load, the combustion pressure and ROHR were increased, and the CO and PM emissions decreased. However, the NOx emission was increased due to the rise of the combustion temperature.

Our environment is faced with serious problems related to the air pollution from automobiles in these days. In particular, the exhaust emissions from the diesel engines are recognized main cause which influenced environment strong. In this study, the potential of biodiesel fuel and oxygenated fuel (ethylene glycol mono-n-butyl ether; EGBE) was investigated as an effective method of decreasing the smoke emission. The smoke emission of blending fuel (EGBE 0~20 vol-%) was reduced in comparison with diesel fuel and it was reduced approximately 64% at 2000 rpm, full load in the 20% of blending rate. But torque and brake specific energy consumption (BSEC) didn't have no large differences. But, NOx emissions from biodiesel fuel and EGBE blended fuel were increased compared with diesel fuel.

Numerical analysis was performed to analysis the structural characteristics of the head device in the road mower system. The head device connects mower system with the boom of the special vehicle. The system with various road surface conditions is subjected to continuous vibration and repeated load. Especially, the maximum equivalent stress occurs in the pillar of the head device, and the maximum equivalent strain also occurs in the fixed plate that supports the mower system. Fatigue analysis results show that the upper end of the pillar is very vulnerable. This analysis results can be used as basic data for optimal road mower head system design.

By controlling the piston speed of the gas spring applying to the digital television stand application of the gas spring, a user can operate the elevation when the gas spring is working under long stroke(200~300 mm, the TV elevation displacement). According to stroke, by some devices with the problem rising from between the difference of external forces, the emotional quality in television elevational function is realized. The piston speed control technique is investigated to perform this experiment piston flow analysis and flow rate control for precise tubular cross section and propose a piston structure for elevation action. This study is for the development of the gas spring of the large size television stand with 50 inch over. In the gas spring development of elevation working, a device to compensate for the volume of the cylinder is generated as much the volume of the piston rod. As this study result, at the development of working gas spring, the hollow shaft is more favorable than the solid one in the apparatus to compensate for the cylinder volume generated.

As a part of light weight, the adhesive has been applied to joint the mechanical structure. The porous material is used with aluminum foam in case of the structure bonded with only adhesive. In order to confirm the durability, it is necessary to investigate the fracture toughness at the bonded joint. So, the fracture property at joint interface of aluminum foam different from the non-porous material becomes especially important. In this study, the static facture analysis was carried out with DCB specimen bonded with adhesive as the loading type of mode Ⅲ. The thicknesses of specimens are 35, 45 and 55 mm. When the forced displacements 5 mm applied on the specimen proceed at specimen thicknesses of 35, 45 and 55 mm, the maximum stresses is shown to be happened at the range from 3.3 MPa to 3.6 MPa. The maximum equivalent stress happened at the specimen thickness of 35mm becomes highest among four kinds of specimens. The static experiment is carried on in order to verify these analyses representatively. As the experimental data become similar with the simulation data, it is thought that these analysis data can be applied at analyzing them into the adhesive joint of real porous material.

Emission regulation by Europe and the U.S. on air pollutants from diesel automobiles which include particulate matter and nitrogen oxides are becoming stricter than ever. The SCR uses Urea, which is NH3 diluted by water, and chemically reacts with emission gases reducing over 90% of the NOx created. In this study several problems were observed in a SCR system and Engine control system. Through this analysis we can find out more effective repair factors from the various fault in SCR component.

The present study is the development of recyclable micro pale expansion drilling bit. The domestic market will gradually be suppressed by the new developed ring one in the use of ring bit(non-recyclable) in this business. Existing casing drilling and insertion method is applied by order of the casing inserted after drilling, which has the disadvantage that a long construction time, device costs and labor consuming. When the steel pipe multi-bit-only expansion drilling is developed, enterprise sales and employment effects can occur. If the performance of the developed products through the product equal to or superior to the domestic component parts are developed proprietary technology acquisition and cost savings, as well as the construction period of about 30%, and the expected reduction of 70% in material costs are expected.

CFRP has the high strength and low weight. But it tends to be frail if it is applied with the mechanical bonding method using weld, rivet or bolt. So, the chemical bonding method using the special adhesive has been utilized. By applying the bonding method with the adhesive, this paper investigates the mechanical property of DCB specimen bonded with the type of mode 2 through the simulation analysis. Four kinds of specimen thicknesses are 25mm, 35mm, 45mm and 55mm in this study. The mechanical behaviors of specimens due to the forced displacements are investigated as the distributions of equivalent stresses. The reaction force becomes higher as the specimen thickness is increased. The result of this study about the fracture property of adhesive joint is thought to be contributed to the safe design of structure with CFRP.

Graphene could be damaged and contain impurities on its surface while several fabrications such as deposition, etching, and patterning because one needs photoresist masking operation to divide the section for deposition or not. In this paper, we investigated the effectiveness of selective atomic layer deposition for clean graphene surface. Atomic layer deposition (ALD) has strong point at very uniform conformity of 1 rms roughness. In this process, H2O is generally used by one of precursors. This H2O precursor make deposition of ALD on hydrophilic surface not hydrophobic. Therefore, we used this property at graphene which has hydrophobic surface. And then, we analyzed selective deposition of ALD on graphene which are grown on Cu foil and transferred by wet process not cleaved from HOPG.
