Individuals responsible for quality management system, implementation, and auditing to the AS9100:2016 series of standards for Aviation, Space, and Defense will require an understanding of the requirements for the preparation and execution of the audit process as defined in these revised standards. Management and implementers of AS9100:2016 Rev. D within these organizations must also be aware of what these requirements mean for their company.
HMI design is an Interdisciplinary, which is based on human cognitive psychology and combines humanities, sociology, aesthetics, information science and other disciplines. While automotive technologies can be applied regardless of regions, HMI must be localized, as it is closely related to regional culture, people's living habits and characteristics. At the same time, HMI design has its own complete theoretical system, research and design methods and testing methods, instead of relying on experience. The purpose of this course is to equip people involved in the automotive industry with a basic sense of HMI design of vehicles.
Static perceptual quality is the term applied to the customer’s first impression of a car at the beginning of the buying process including how it looks, feels, and smells. This “first feeling” largely determines whether the customer continues through the purchase process. At present, OEMs have no systematic method for static perceptual quality in the whole vehicle design and development process, especially for the static perceptual quality review in the early stage of design and development before data freezing. Usually, it can only be evaluated after the vehicle is produced and assembled.
The fuel economy of recent small size DI diesel engines has become more and more efficient. However, heat loss is still one of the major factors contributing to a substantial amount of energy loss in engines. In order to a full understanding of the heat loss mechanism from combustion gas to cylinder wall, the effect of hole size and rail pressure under similar injection rate conditions on transient heat flux to the wall were investigated. Using a constant volume vessel with a fixed impingement wall, the study measured the surface heat flux of the wall at the locations of spray flame impingement using three thin-film thermocouple heat-flux sensors. The results showed that the characteristic of local heat flux and soot distribution was almost similar by controlling similar injection rate except for the small nozzle hole size with increasing injection pressure.
In the present work, a relative comparison of addition of water to diesel through emulsion and fumigation methods is explored for reducing oxides of nitrogen (NOx) and smoke emissions in a production small bore diesel engine. The water to diesel ratio was kept the same in both the methods at a lower concentration of 3% by mass to avoid any adverse effects on the engine system components. The experiments were conducted at a rated engine speed of 1500 rpm under varying load conditions. A stable water-diesel emulsion was prepared using a combination of equal proportions (1:1 by volume) of Span 80 and Tween 80. The mixture of Span 80 in diesel and Tween 80 in water was homogenized using an IKA Ultra Turrax homogenizer with tip stator diameter 18mm at 5000 rpm for 2 minutes. The water-in-diesel emulsions thus formulated were kinetically stable and appeared translucent. No phase separation was observed on storage for approximately 105 days.
