Biodiesel as alternative energy source of the traditional petroleum fuels has increased interest, because environmental pollution based exhaust emissions from vehicle became serious. The advantage of biodiesel produced from esterification of vegetable and animal oils can be used without the modification of existing diesel engine, but glycerin is generated by production process. In this study, the usability of non-esterification biodiesel as an alternative fuel was investigated in a indirect injection diesel engine. The non-esterification biodiesel has not generated glycerin in esterification process and reduced the 20 percent of cost because it has not used methanol in the production process. Experiments were conducted by using the 5, 10 and 20 percentage of biodiesel and 4 and 8 percentage of biodiesel with 1 and 2 percentage of WDP in baseline diesel fuel. The smoke emission of biodiesel was reduced in comparison with diesel fuel, but power, torque and brake specific energy consumption was similar to diesel fuel.

Since the expectations and demand for higher ride comfort of the customers (driver and passengers) have been dramatically increased, new vehicle model launched on the market have not only better performance and design-wise appealing, but also ride comfort has to be increasingly better than its predecessor. Automotive manufactures have focused on the increasing human thermal comfort. To achieve a high thermal comfort, most manufacturers provide a system for their cars to ensure ventilation, heating and cooling air in the passenger compartment. As results, the influence of the seats and situations in the thermal human comfort are considered. And, the temperature distribution pattern on the human face is acquired at natural condition, both warm condition on which seat is managed around 30℃ and hot condition on which seat is managed around 50℃.

The tyre/road noise becomes aggravated due to the rapid increase of motor vehicles. It has a great effect on the dwelling environment. Therefore we investigate the characteristics and sources of the tyre/road noise through grasping the status of the tyre/road noise. Traffic noise results from the collective contribution of the noise produced by individual motor vehicles. The tyre/road noise varies enormously depending upon its type and mode of operation. In this study, we investigate the noise labelling of EU tire.

An air cleaning unit(ACU) in a nuclear power plant plays a role on cooling the safety-related components whose function is involved in the reactor shutdown, and maintains the suitable temperature and humidity for work in the rooms where an operator is working on. To guarantee the performance of the unit the design of ACU should be subject to credible codes and standards, such as ASME, ANSI and ASHRAE, etc. On top of them, the desorption of the carbon adsorber is addressed in ASME N509 which causes the adsorber no longer to capture the iodine isotopes produced by the severe accident. In this study, the equations of the heat source were derived from the radioactive decay heat of each iodine isotopes. From the resultant equation, the maximum temperature below 300oF for the desorption was calculated under a proposed condition and analysed with the reference results.

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 tapered double cantilever beams(TDCB) with the type of mode Ⅲ are manufactured with aluminum foam. The fracture toughness at the joint of the structure bonded with only a adhesive can be obtained. The static analyses are carried out and verified the results by the experiment. As the results of static analyses, the reaction forces ranged from 0.30 to 0.41 kN at all specimens are shown when the forced displacements are proceeded as much as 7 to 9 mm. As the results of analyses and experiments are compared with each other, there is a little bit of difference between these results. Through the result of this study, the mechanical properties at TDCB specimens with the type of mode Ⅲ can be understood.
