High Efficiency Combustion Systems With the increased demands for fuel efficiency and fuel economy, the internal combustion engine (ICE) continues to be examined for design enhancements to improve these measures. Overall, the program will examine several technological advances required to maximize efficiency, including: o Advanced, low-temperature combustion techniques o Improved understanding and modeling of heat loss mechanisms o Electrification and intelligent control of accessory loads o Possible redesign of mechanical systems (e.g., variable stroke for fully expanded cycles) o High-efficiency turbo-machinery to extract exhaust energy and provide boost Emissions Reduction With a greater than 10 percent growth expected in the domestic passenger vehicle market, China now has the world’s largest auto market; and emissions from transportation are growing rapidly as well.

The ability to quickly and accurately model vapour cycle systems is of increasing interest to a diverse range of industrial applications where energy is lost in the form of ‘waste heat’ from a combustion process. This is especially the case for the Organic Rankine Cycle (ORC), which has long been associated with Combined Heat & Power (CHP) plants and small-scale power generation due to its ability to recover heat from relatively low grade engery sources such as biomass, geothermal and solar. However, vehicle manufacturers are also realising the opportunity of recovering some of the 60-70% of fuel energy that is normally lost to the surroundings. Indeed ORC systems are particularly well suited to recovering heat from the vehicle’s exhaust, or liquid cooling system. The recovered energy is used to heat the working fluid to a superheated vapour which is then expanded using either a turbine or a postive displacement machine to extract useful work.

On-board diagnosis of engine and transmission systems has been mandated by government regulation for light and medium vehicles since the 1996 model year. The regulations specify many of the detailed features that on-board diagnostics must exhibit. In addition, the penalties for not meeting the requirements or providing in-field remedies can be very expensive. This course is designed to provide a fundamental understanding of how and why OBD systems function and the technical features that a diagnostic should have in order to ensure compliant and successful implementation.

Stringent requirements of reduced NOx emission limits in the US have presented engineers and technical staff with numerous challenges. Several in-cylinder technical solutions have been developed for diesel engines to meet 2010 emission standards. These technologies have been optimized and have yielded impressive engine-out results in their ability to reduce emissions to extremely low levels. However, current and state-of-the-art in-cylinder solutions have fallen short of achieving the limits imposed on diesel emissions for 2010.

As diesel emissions regulations have become more and more stringent, diesel particulate filters (DPF) have become possibly the most important and complex diesel aftertreatment device. This seminar covers many DPF-related topics using fundamentals from various branches of applied sciences such as porous media, filtration and materials sciences and will provide the student with both a theoretical as well as an applications-oriented approach to enhance the design and reliability of aftertreatment platforms.

Meeting the requirements of heavy-duty engine emissions regulations is a challenge for all engine manufacturers. Since the introduction of Exhaust Gas Recirculation (EGR) in medium and heavy-duty diesel engines, these systems have become more sophisticated and tightly integrated with emission control systems. This 2-day seminar will explore the advantages and disadvantages of EGR and the most effective implementation of various EGR systems. This seminar will begin by defining EGR and why it is used in diesel engines, along with an explanation of the mechanisms by which EGR is able to reduce NOx.

The diesel engine noise is classified into mechanical noise, flow dynamic noise and combustion noise. Among of them, the combustion noise is higher than the others due to diesel combustion high compression ratio and auto ignition. The injected fuel is mixed with air in ignition delay process, followed by simultaneous ignition of premixed mixture. This process results in rapid pressure rise which is the main source of the combustion noise. The amount of fuel burned during premixed combustion is mainly affected by the ignition delay. The EGR rate has impact on the ignition delay, and thus it influences combustion noise characteristics. Therefore, during the transient state, combustion noise characteristics changes as the EGR rate deviates from the target value. Therefore, in this study, the effect of EGR rate deviation during transient state the combustion noise is studied. The 1.6 L diesel engine with a VGT was used for the experiment.

Aircraft noise development program involves highly integrated system from diverse disciplines such as weight, propulsion, structure, stress, aerodynamic, avionics, flight control, etc… And aircraft noise is, without doubt, no exception to it. From aircraft system perspectives, noise control and design guideline must be included in the design phase as early as possible in order to reach aircraft noise requirements. The different requirements defined the early design phase provide a conventional breakdown of the work package that must blend into the organization. The presentation will focus on 3 aspects: 1) Sustainable growth can only be achieved through an environmental responsibility. COMAC is currently developing a new narrow-body aircraft, the C919 by not only meeting current regulations for community noise, but by exceeding them as well as future ones.
