Engineers are taught to create designs that meet customer specifications. When creating these designs, the focus is usually on the nominal values rather than variation. Robustness refers to creating designs that are insensitive to variability in the inputs. Much of the literature on robustness is dedicated to experimental techniques, particularly Taguchi techniques, which advocate using experiments with replications to estimate variation. This course presents mathematical formulas based on derivatives to determine system variation based on input variation and knowledge of the engineering function.

Anti-Hop Clutches are popular for bikes above 400 cc. They offer the advantage of better driving stability in lower gears and during down shifting. The currently used designs of such clutches are having different constructions with complex geometry parts and almost 30% more number of parts (compared to standard clutch) are used in some designs to achieve the desired 'Driving Assist' and 'Coasting Slip' effect. The production process used, demands for specialized tools for manufacturing the complex geometry of parts and the price of the clutch assembly is more than double as compared to standard, equivalent design of multi plate wet clutches. These type of clutches are commonly known as - Anti Hop Clutch or Slipper Clutch or Assist and Slip clutches. To achieve same performance benefits with simpler design, less number of parts with a Flexibility to alter the Assist and Slip effect to suit the application, Endurance Technologies Ltd. developed a new concept.

The main purpose of Student Formula Japan competition (hereafter called “SFJ”) is to let students learn the basic ability necessary for engineers through design, fabrication and test projects. In this study the authors decided to adopt Honda BC-PC37E which was an engine for motor cycles. Then the engine have strength enough for the light weight, downsizing design. As the course of the competition consists of short straights and many corners for running within equal to or less than middle speed range, the engine must have excellent acceleration performance to reduce the lap times in the corners. The effective engine performance is necessary for the flat torque in all of engine speed range, especially in low engine speed range. As the regulation allows that a turbocharger is fitted to an engine, its introduction is effective for getting high torque in the low engine speed range.

The main purpose of this paper will be to investigate if a small snowmobile gasoline Direct Injected (DI) two-stroke engine has the potential to be adapted for two other types of applications: as a range extender (REX) for electric vehicles and for a motorcycle application. For the REX application, the main requested specifications (NVH, lightweight, compactness, minimum production cost and easy maintenance), correspond well to the main features of DI 2-stroke engines. The potential of a modified production engine operating in part load ultra-low NOx Controlled Auto Ignition (CAI) to meet the Euro 6 emissions standards on the NEDC cycle has already been demonstrated in a previous paper. In the first part of this new paper, we will investigate which solutions can be used to maintain this potential with even stricter legislations based on Euro 6d, WLTP cycle and Real Driving Emissions (RDE).

Abstract In today’s cost-competitive automotive market, use of finite element simulations and optimization tools has become crucial to deliver durable and reliable products. Simulation driven design is the key to reduce number of physical prototypes, design iterations, cost and time to market. However, simulation driven design optimization tools have struggled to find global acceptance and are typically underutilized in many applications; especially in situations where the algorithms have to compete with existing know-how decision making processes. In this study, systematic multi-phase approach for optimization driven design is presented. Approach includes three optimization phases. In first phase, topology optimization is performed on concept BIW design volume to identify critical load paths. Architectural inputs from topology are used to design base CAD.

Abstract Power-split configuration is highlighted as the most popular concept for full hybrid electric vehicles (HEV). However, the energy management and design of power-split heavy duty truck under Chinese driving conditions still need to be investigated. In this paper, the parametric design, a rule-based control strategy and an equivalent consumption minimization strategy (ECMS) for the power-split heavy duty truck are presented. Besides, the influence of a penalty factor also discussed under ECMS algorithm. Meanwhile, two different methods to search the engine operation point have been proposed and the reason of different economy performance is presented by using energy flow chart. And the simulation results show both fuel consumption can satisfy the second phase fuel consumption standard and the third phase fuel consumption standard which will be implemented in 2020, under C-WTVC (Chinese-World Transient Vehicle Cycle).

Fundamentals of Integrated Vehicle Realization is a unique and solid contribution to the subject of product development, centered on the automotive industry. Automotive manufacturers and suppliers are under pressure to transform themselves and deliver a higher level of product refinement coupled with more functionality. This could lead to the sprouting of organizational structures not in alignment with the required product development phases. Consequently, many product development initiatives may be cancelled or dropped at later stages despite all the efforts and financial investments. Therefore, it is vital that organizational unity be always intact during any transformation. A highly effective organization should always act as one cohesive entity dedicated to serving the customer with creative aptitude, integrative skills, analytical thinking, and synergistic management.
