Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%.

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.

Designing more efficient and robust emission control components and exhaust systems results in more efficient performance, reduced backpressure and fuel penalty, and higher conversion efficiency. This course will help you to understand the motion of exhaust flow in both gasoline and diesel emission control components including flow-through and wall-flow devices such as catalytic converters, NOx adsorbers, diesel oxidation catalysts, diesel particulate filters as well as flow through the overall exhaust system.

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.

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.

The potential of internal EGR (iEGR) and external EGR (eEGR) in reducing the engine-out NOx emissions in a heavy-duty diesel engine has been investigated by means of a refined 1D fluid-dynamic engine model developed in the GT-Power environment. The engine is equipped with Variable Valve Actuation (VVA) and Variable Geometry Turbocharger (VGT) systems. The activity was carried out in the frame of the CORE (CO2 Reduction for Long Distance Transport) Collaborative Project of the European Community, VII FP. The engine model integrates an innovative 0D predictive combustion model for the simulation of the HRR (heat release rate), which is based on the accumulated fuel mass approach, and a multi-zone thermodynamic model for the simulation of the in-cylinder temperatures. NOx emissions are calculated by means of the Zeldovich thermal and prompt mechanisms.

Design and optimization of automotive engines present unique challenges on account of the large design space and conflicting constraints. Optimizing the fuel consumption and reducing emissions over a driving cycle is a good example. Inlet pressure, equivalence ratio, humidity, EGR fraction, inlet air temperature, ignition timing, engine load, engine speed (RPM) etc. each impact fuel consumption and emissions and thus represent a vast parametric space to conduct de sign and global optimization studies. This large parametric space is further increased when one has to consider newer fuels and fuel-blends (varying ratios of fuel-additive mixtures) further complicating the design-optimization problem. The large design parameter space precludes the use of detailed numerical or experimental investigations. Physics-based reduced-order models (quasi-dimensional models) can be used effectively in the design and global optimization of such problems.

This work concerns the modelling of soot formation process during n-dodecane and diesel spray combustion under engine-like conditions. The key aim is to investigate the effects of chemical kinetics on soot formation characteristics at different ambient temperatures. Numerical computation is performed using an open-source computational fluid dynamics software. Prior to simulating the diesel combustion, numerical models including a revised multi-step soot model is validated by comparing the experimental data of n-dodecane fuel in which the associated chemistry is better understood. In the diesel spray simulations, a single component n-heptane model and the multi-component Diesel Oil Surrogate (DOS) model which uses a reduced toluene sub-mechanism to represent the aromatic compound are adopted. The third mechanism used comprises skeletal chemical mechanisms of n-hexadecane and heptamethylnonane.
