“…Also it is a difficult task to test each design of the TEG subsystem through physical experiments. Hence, several methods were developed to predict the performance of TEG which applied for the engine exhaust heat recovery [9,10]. Among of these methods, computational fluid dynamics (CFD) proved to be a solution which can predict the heat transfer and power regenerating process accurately [11].…”

As a low maintenance solid state device, the thermo-electric generator (TEG) provides an opportunity to recover energy from the exhaust gas directly. In this paper, dynamic behaviour of a TEG applied to the EGR path of a non-road diesel engine has been analysed. Through the component in the loop (CIL) method, the proposed TEG was simulated by a virtual model in real time. A Nonlinear Auto-regressive exogenous (NLARX) model was operated in an xPC as the virtual model. Based on calculated results of the model, the position of EGR valve and the coolant valve were adjusted to simulate the effect of TEG installation on the gas flow in EGR path. Analysis of the TEG performance under Non-road Transient Cycle (NRTC) was conducted base on above method. With above analysis, following conclusions can be drawn. First, the component in the loop simulation method demonstrates a better performance to predict the TEG dynamic behaviour comparing to the software based methods. Using component in the loop methodology, transient performance of the TEG device can be predicted with a satisfied error range. Besides of the TEG performance prediction, the effect of the installation of the TEG was also analysed. The temperature variation and the pressure drop which affected by TEG system were predicted, and a more accurate TEG performance prediction can be achieved accordingly.

Introduction to Diesel Emissions

This chapter presents a concise treatment of diesel engine exhaust emissions and its mitigations. The working principle of the diesel engine is first given to establish the background and further to describe the influence of various parameters that affect the formation of engine exhaust emissions. The factors that influence exhaust emissions are linked to the engine design and the operating factors that promote good fuel-air mixing and combustion. These factors are air induction, fuel injection equipment, fuel injection schemes, in-cylinder gas exchange process and heat transfer. Thermochemistry essentially gives insight to the global reaction kinetics and how this is applied in practical engine combustion determinations in terms of equivalence ratios. Based on these, the fuel spray structure, atomization, penetration and the spray combustion model are described. The formation of exhaust emissions such as carbon monoxide, unburnt hydrocarbon and its intermediates, oxides of nitrogen and soot in diesel engines has been discussed. The techniques of their mitigation from the view of internal factors that deals with the optimization of engine design and it performance, as well as various exhaust after-treatment techniques used for NO x and soot reduction have been briefly discussed.
