Abstract This paper describes the evolution of a family of modern four stroke high power density engines, the Ruston RK215 series, which has been developed to meet the specific needs of heavy duty rail traction application including the current EPA and UIC (European) emissions legislation. It discusses the extensive experience of Ruston in powering various locomotives including recent applications in overseas markets. The methodology adopted in the base engine design, to achieve high reliability and good component life is discussed with methods of validation and risk analysis during the design and development program. Specific reference is made to an emissions research program to ensure the engine will comply fully with future legislation.

This paper describes the development of a low-emission, 50-kW turbine-driven generator called a turbogenerator. It gives a detailed description of the key design features that benefit hybrid electric vehicles driven in various driving cycles. Although the turbogenerator is designed for hybrid electric vehicles, other applications such as standby and primary electric power generation will benefit from its characteristics. These include very-low-exhaust emissions, low cost, high reliability, high fuel efficiency, compact design, and low noise levels. The turbogenerator is relatively unique in that the turbine wheel, compressor impeller, and electrical generator are all mounted on a single, common shaft which is supported on air bearings. These features eliminate the need for both the gearbox and oil lubrication commonly found on conventional automotive and gas turbine engines. AlliedSignal developed the 50-kW turbogenerator for Ford Motor Company under the DOE Hybrid Electric Vehicle Propulsion Program. The turbogenerator is designed to fit into the engine compartment of a Mercury Sable. AlliedSignal originally proved this innovative concept in an APU development program for the U.S. Army. The unit developed for that program has accumulated over 600 hours of operation in laboratory and Army vehicle tests.

Electronic devices such as medical instruments implanted in the human body and electronic control units installed in automobiles have a large impact on human life. The electronic circuits in these devices require highly reliable operation. Radiographic testing has recently been in strong demand as a nondestructive way to help ensure high reliability. Companies that use high-density micrometer-scale circuits or lithium-ion batteries require high speed and high magnification inspection of all parts. The authors have developed a new X-ray source supporting these requirements. The X-ray source has a sealed tube with a transmissive target on a diamond window that offers advantages over X-ray sources having a sealed tube with a reflective target. The X-ray source provides high-power-density X-ray with no anode degradation and a longer shelf life. In this paper, the authors will summarize X-ray source classification relevant to electronic device inspection and will detail X-ray source performance requirements and challenges. The paper will also elaborate on technologies employed in the X-ray source including tube design implementations for high-power-density X-ray, high resolution, and high magnification simultaneously; reduced system downtime for automated X-ray inspection; and reduced dosages utilizing quick X-ray on-and-off emission control for protection of sensitive electronic devices.

MHI recently developed a 1600°C class J-type gas turbine, utilizing some of the technologies developed in the National Project to promote the development of component technology for the next generation 1700°C class gas turbine. This new frame is expected to achieve higher combined cycle efficiency and will contribute to reduce CO2 emissions. The target combined cycle efficiency of the J type gas turbine will be above 61.5% (gross, ISO standard condition, LHV) and the 1on1 combined cycle output will reach 460MW for 60Hz engine and 670MW for 50Hz engine. This new engine incorporates: 1) A high pressure ratio compressor based on the advanced M501H compressor, which was verified during the M501H development in 1999 and 2001. 2) Steam cooled combustor, which has accumulated extensive experience in the MHI G engine (> 1,356,000 actual operating hours). 3) State-of-art turbine designs developed through the 1700°C gas turbine component technology development program in Japanese National Project for high temperature components. This paper discusses the technical features and the updated status of the J-type gas turbine, especially the operating condition of the J-type gas turbine in the MHI demonstration plant, T-Point. The trial operation of the first M501J gas turbine was started at T-point in February 2011 on schedule, and major milestones of the trial operation have been met. After the trial operation, the first commercial operation has taken place as scheduled under a predominantly Daily-Start-and-Stop (DSS) mode. Afterward, MHI performed the major inspection in October 2011 in order to check the mechanical condition, and confirmed that the hot parts and other parts were in sound condition.
