Tuning the many electronic variables to ensure that a vehicle's engine performs according to its mission profile ultimately relies upon a competent calibrator. Because proper calibration is a critical aspect of customer satisfaction and emissions certification, skilled calibrators are in high demand in the auto industry. This Academy is designed to provide a foundation for those interested in entering the field of calibration engineering through hands-on exercises and detailed instruction on the base principles of calibration.

Training / Education Classroom Seminars
Engine failures can occur in a variety of equipment, vehicles, and applications. On occasion, a single vehicle type or equipment family will even experience multiple engine failures leading to the inevitable need to determine what the most likely cause of one or all of those failures was. This comprehensive seminar introduces participants to the methods and techniques used to understand the types of variables and inputs that can affect engine reliability and then determine the most likely cause of an individual engine or group of engine failures in the field.

Public awareness regarding pollutants and their adverse health effects has created an urgent need for engineers to better understand the combustion process as well as the pollutants formed as by-products of that process. To effectively contribute to emission control strategies and design and develop emission control systems and components, a good understanding of the physical and mathematical principles of the combustion process is necessary. This seminar will bring issues related to combustion and emissions "down to earth," relying less on mathematical terms and more on physical explanations and analogies.

Abstract An effective way to reduce greenhouse gas emissions (GHGs) is to use rurally produced straight jatropha oil as a substitute for diesel fuel. However, the different physical and chemical properties of straight vegetable oils (SVOs) require a customized setup of the combustion engine, particularly of the injection timing and quantity. Therefore, this study demonstrates the differences in the injection and combustion processes of jatropha oil compared to diesel fuel, particularly in terms of its compatibility with exhaust gas recirculation (EGR). A 2.2 l common-rail diesel engine with a two-stage turbocharging concept was used for testing. To examine the differences in injection rate shaping of diesel fuel and jatropha oil, the injector was tested with an injection rate analyzer using both the fuels. To investigate the combustion process, the engine was mounted at an engine test bench and equipped with a cylinder pressure indication system.

The sixth stage of light-duty vehicle emission standard was promulgated by the Ministry of Environmental Protection of China on 23 Dec, 2016. The new emission standard contains two stages, namely China-6a and China-6b, and will be effective from Jul, 2020 and Jul, 2023 respectively. This presentation addresses the background of China-6, basic principles for drafting China-6 and the dominant differences between China-6 and its ancestors. This presentation also highlights the new challenges associated with the introduction of WLTC as test cycle, new requirements for low-temperature test and evaporative and refilling emissions, changes in OBD regulation, and particularly RDE test.

Meeting increasingly stringent emissions standards and, the tradeoff between emissions and efficiency necessitate research of new technologies and innovation. According to DOE, on-road vehicles account for 60% of the fossil fuel consumption and 25% of the greenhouse gas emissions in USA. All the leading indicators project that these shares will go up mostly due to the additional vehicles on the road even when significant gains will undoubtedly be made in fuel economy through the use of innovative technologies.

Global fuel economy and CO2 mandates require a substantial increase in vehicle fuel efficiency over the next several years. Vehicle electrification will clearly play an increasing role, as will efforts to reduce vehicle mass, friction, aerodynamic drag, and rolling resistance. However, efficiency improvements to the internal combustion engine must continue, since it will be the dominant automotive propulsion source for many years to come. New technologies will continue to be developed as the internal combustion engine evolves. To be successful, these technologies cannot focus exclusively on efficiency and emissions. They must also maintain fun-to-drive performance and deliver their benefits at an affordable cost. Cylinder deactivation systems are one technology that allows internal combustion engines to function more efficiently without sacrificing performance.

The conventional design and manufacturing approach of electric drive is to design electric motor and gearbox/transmissions separately then assemble. As electric drive technologies evolve, these major parts are designed together with new key components and controls, leading to better performance, lower NVH, smaller package and lighter weight. This presentation provides an update of such development in China's "New Energy Vehicle (EV and plug-in hybrid)" market in both passenger vehicles and commercial vehicles. Jing-Jin Electric, the leading electric drive supplier in China, has developed such integrated motor-transmission solutions with applying its innovative electromagnetic dog clutch (EMDC) in both hybrid system and 2-speed transmissions.
