Kinki University formula project has been participating in the student Formula SAE of Japan (JSAE) every year for the Competition since the second time. The engine uses ZX-6R made by Kawasaki Heavy Industries for the Competition from the eighth time. “Improvement of limited performance” is inserted in the concept through the development of a power train. Supercharger loading, engine dry sump and engine cooling management were improved. 59.6 kW (80.6 PS) /9000 rpm of maximum output and 70.6 Nm (7.2 kgf m)/8000 rpm of maximum torque were achieved by the supercharger loading. We succeeded in getting 90% of torque band (4000∼10000rpm) by 50% of the number of revolutions in regular use (2000∼12000rpm). Using the dry sump system, hydraulic pressure constantly managed hydraulic pressure at the time of engine operations; the system, where the engine stops at the time of hydraulic pressure fall, was also built.

As congestion increases and commute times lengthen with the growing urbanization, many customers will look for effective mobility solutions. Two-wheeler are one of the solutions to deal with these issues, in particular if equipped with electrified powertrains for minimized local noise and air pollutant emissions. Scooters powertrain technology is predominantly based on Spark Ignition Engine (ICE) associated with a Continuously Variable Transmissions (CVT) and a Centrifugal Clutch. Nevertheless, even though CVT gives satisfaction in simplicity, fun to drive, cost effectiveness and vehicle dynamics, its efficiency is an undeniable drawback. Indeed, a conventional CVT is wasting more than 50% of ICE effective power in customer driving conditions. Consequently, those vehicles have high fuel consumption relative to their size, and are equipped with overpowered and heavy internal combustion engines, allowing a large area for further improvements.

In consideration of the fact that in extreme Enduro competitions two-stroke motorcycles are still dominating, the Institute of Internal Combustion Engines and Thermodynamics, Graz University of Technology, with a long tradition in two-stroke technology, has developed a new 300 cm3 two-stroke motorcycle engine. The 2-stroke LPDI (Low Pressure Direct Injection) technology was originally developed for the 50 cm3 Scooter and moped market in Europe. In 50 cm3 applications the LPDI technology fulfils the EURO 4 emission standard (2017) [1]. In a next step the LPDI technology was applied to a 250 cm3 Enduro engine demonstrator vehicle. Based on the results of the demonstrator, a complete new high performance 300 cm3 engine was developed. The development of this new engine will be described in this publication. Some interesting aspects of the layout with 3D-CFD methods and also 1D-CFD simulation to optimize the exhaust system by DoE methods are discussed in the paper.

The main purpose of Formula SAE Competition (hereafter called “FSAE”, “Formula Society of Automotive Engineering”) is to let students learn the basic ability necessary for engineers through design, fabrication and test projects. Higher running performance of a manufactured vehicle is one of the most important themes that should be studied in Student Formula Japan Competition (hereafter called SFJ Competition). Also, SFJ Competition is the series of the FSAE. the purpose of this study, the chassis must be required light weighting and high stiffness. The former can reduce the centrifugal force and the inertial force in the turning and the latter can contribute to demonstrate the suspension performance according to design [1], [2], [3], [4]. The SFJ Competition has Skid Pad event to compete for steerage responsiveness and high suspension performance on turning.

The automotive trend towards increased levels of electrification is showing a clear direction for hybrid technologies. Nowadays Mild- and plug-in-hybrids open a very wide area of future developments whereas battery electric vehicles (BEV) are still evident but still perceived as niche products with limited production volumes. Nevertheless, major OEMs are working on these kinds of vehicles and have also brought such EV concepts into series production. All of these designs show a clear trend that, beside the topic of electric traction motor and energy storage systems, the internal combustion engine (ICE) is also coming into focus again. In many of these vehicles the range extender (RE) unit is foreseen as an emergency unit to recharge the batteries if the state of charge (SOC) is too low. One of the major advantages of a BEV over other designs is the very good acoustic behavior, so the NVH performance becomes the most challenging topic for RE development.

In motorcycles, the size and output performance of the engine itself has a major effect on the maneuverability of the motorcycle. In particular for cases where a high output engine is mounted on a lightweight frame, these effects are even more of a concern. In the case of developing a racing motorcycle with a high power engine, the behavior of the motorcycle differs depending on the output range used and there are a lot of cases where changes to the basic dimensions of the motorcycle as well as the main components are required. Here, there are a lot of cases where the rider and drive-able courses are limited to compatibility with distinct specifications and when considering use as a general mass production motorcycle by riders with varying levels of skills and in various environments, it difficult to determine how to provide support.

The demand for lighter, smaller, more efficient, and more powerful engines calls for a rethinking of the traditional internal combustion engine (ICE). This paper describes development progress of LiquidPiston's small rotary engine, the XMv3, which operates on a Spark-Ignited (SI) variant of its patented High Efficiency Hybrid Cycle (HEHC). This thermodynamic cycle, which combines high compression ratio (CR), constant-volume combustion, and overexpansion, has a theoretical efficiency of up to 75 percent using air-standard assumptions and first-law analysis. XMv3 displaces 70cc (23cc per each of three working chambers) and is gasoline fueled. The engine is simple, having only two primary moving parts, which are balanced to prevent vibration.

WIP Standard
GEIAHB0007C
This handbook is intended to provide additional information on the use and tailoring of the data in GEIA-STD-0007. The standard provides a new approach to Logistics Support Analysis Record (LSAR) (i.e., MIL-STD-1388-2B) data with emphasis on data transfer (e.g., XML Schemas) versus data storage (e.g., relational tables). GEIA-STD-0007 identifies the range of logistics product data that is generated during the development and acquisition of a system or end item. It does not prescribe the supportability analyses required to generate logistics product data. How the data is generated via analysis techniques/tools, how it is stored and processed, and how the data is used to generate specific logistics support products, is left to the performing activity. GEIA-STD-0007 is a data transfer standard implementing the logistics data concepts of GEIA-STD-927, Common Data Schema for Complex Systems.

GEIASTD0007C
This standard defines logistics product data generated during the requirements definition and design of an industry or government system, end item or product. It makes use of the Extensible Markup Language (XML) through the use of entities and attributes that comprise logistics product data and their definitions. The standard is designed to provide users with a standard set of data tags for all or portions of logistics product data and customer defined sub-sets of logistics product data. The standard can be applied to any indsutry or government product, system or equipment acquisition program, major modification program, and applicable research and development projects. This standard is for use by both industry and government activities. As used in this standard, the requiring authority is generally the customer and the customer can be a government or industry activity. The performing activity may be either a industry or government activity.

GEIASTD0008A
This Standard specifies the minimum derating requirements for using electronic components in moderately severe environments. These environments are assumed to include Airborne Inhabited Cargo (AIC), Airborne Inhabited Fighter (AIF), Ground Mobile (GM), and Naval Sheltered (NS) environments specified in MIL-HDBK-217. This Standard is intended to supersede the derating limits contained in Defense Standardization Program Office (DSPO) Standardization Directive SD-18, Naval Standard TE000-AB-GTP-010, and Air Force ESD-TR-85-148. It is intended that a future revision of this Standard will include additional requirements for derating for other environments (e.g. Airborne Uninhabited Cargo). Since this Standard specifies the minimum derating requirements, (sub)contractors may derate in excess of these requirements.
