Abstract The oil flow in the oil ring groove was observed in order to improve the oil ejection efficiency in the oil ring groove. The oil flow was visualized with a clear head piston using fluorescing agent and particles under motoring condition. The influences of oil ring specification on the direction and the velocity of the oil flow were evaluated. The velocity of the oil ring with oil vent holes was faster than that of the oil ring without oil vent holes. In the case of the oil ring with vent holes, the reverse flow of the oil toward the front side was observed in the back clearance. Therefore, oil vent holes can change the oil flow and improve the oil ejection efficiency in the oil ring groove.

This paper focuses on the development of the centralized air flow system S-FLOW (Energy Saving Air Flow Control System). The S-FLOW system directs thermal energy to each seating position in the vehicle based on occupancy, thus prioritizing the energy usage based on the particular scenario. The thermal environment in a vehicle's cabin is non-uniform. If the climate control system is used to direct airflow exclusively to any one region of the cabin, without special considerations, comfort may be adversely impacted. To solve this concern, a non-uniform evaluation method was developed to evaluate comfort at each body region of the occupant using the SET* (Standard new effective temperature) method. SET* is a parameter that combines the effects of temperature, airflow velocity, humidity, and other parameters to quantify thermal comfort. Next, a method was established that correlated each body region's SET* value to the occupant's overall thermal comfort. Using this method, a technique was developed to efficiently apply thermal energy exclusively to body regions which require additional thermal treatment to maintain comfort.

As greater emphasis is placed on the development of small fuel-efficient cars, there is a growing need to reduce the size of the inverter used in hybrid vehicles (HVs). However, semiconductor devices and other components are generating larger amounts of heat and the parts used to cool these components are becoming thinner. One issue resulting from these trends is perforations that propagate from coolant paths. This development secured corrosion resistance by controlling sacrificial corrosion protection performance, optimizing the use of Mn and Si materials to reduce susceptibility to grain-boundary corrosion, and taking a microstructural approach to the flow of the brazing filler metal. The developed material was applied to the inverter cooler of a small HV released at the end of 2011.
