1 Waste heat recovery from heavy duty truck diesel engines T. Henriques Mechanical Engineering Department Instituto Superior Técnico Av. Rovisco Pais, Lisboa Portugal Abstract- This study is focused on the evaluation of the potential energy recovery in internal combustion engines (ICE) for heavy vehicles. Four sources of heat dissipation of an ICE representative were studied. The EGR and the exhaust gas were identified as the best sources of heat to recover. The two hot sources selected are in parallel and the Rankine cycle (RC) also uses as heat sink the cooling system of the ICE. The chosen RC expander is piston type. The RC maintains the pressure and temperature stationary using evaporators of variable geometry and a condenser with variable bypass coolant. It is concluded that ethanol is the working fluid to be used, the RC working at a evaporation pressure of 49 bar, condensation pressure of 2.3 bar and an overheating temperature of 240 C. After optimization, the EGR cooling temperature is 120 C and the exhaust gases cooling temperature varies from 110 C to 230 C, depending on the regime of the ICE. It was selected the heat exchanger with finned tubes for evaporators. The heat exchanger selected for the condenser has concentric tubes with axial flow. The proposed system achieves a maximum reduction of fuel consumption and carbon dioxide (CO 2 ) emissions of 6.6% at high speed. Mechanical power achieves a maximum increase of 7%. The original cooling system is not undersized. Keywords: waste heat recovery in internal combustion engines; Rankine cycle; heavy duty diesel trucks; performance maps; variable geometry heat exchanger. 1. Introduction In the European continent about 75% of the transport of materials is assured by road through trucks. Nowadays the internal combustion engines (ICE)present maximum thermal efficiency of about 40% [3], wasting the remaining energy fraction in form of heat in the various systems of the thermal management of the ICE. It is thus essential to find solutions to improve the performance of these equipments. The cycle of Rankine (RC) presents one the highest potential in the recovery of thermal energy from such systems. In this context, the main objective of the present work is to evaluate the potential for energy recovery from ICE of heavy vehicles. 2.

It was concluded that ethanol was the most suitable working fluid.figure 8 presents the optimum parameters for the RC for all ICE regimes. η e = 70% η p = 80% η RC = 13,75% State Pressure [bar] Temperature [ºC] 1 2, ,3 100 Figure8 T-s diagram of base RC with ethanol and thermodynamic states of cycle. Figure 9 presents the optimum cooling temperature of the exhaust gases. 5. Evaporators Figure 9 Optimum cooling temperature of the exhaust gases. The evaporator is an essential component in any vehicle waste heat recovery application. The following characteristicsare important in such applications: i) Maximization of heat transfer area for hot gases; ii) Minimization of weigth; iii) Compactness with EGR HEX volume limit of ~0.025m 3 and ESC HEX volume limit of ~1m 3 ; iv) Low pressure drop trough the heat exchanger, principally in hot gases flow, with the limit of 0.2bar; v) Easy to make and easy to clean; To implement the RC control strategy, evaporators of variable geometry had to be developed on the side of the hot sources.figure 10 shows the evaporator concept developed with variable geometry. 5

The gates are in lower position. Intermedium load of heat recovery. Some area for hot gases is in utilization. The gates are in intermedium position. Figure10 -Evaporator concept developed with variable geometry. Table 3 presents the main characteristics of the evaporators. The last column of the table represents the standard deviation of the length required for the heat exchanger in the various regimes of the ICE.This parameter is subject to minimization by seeking the best cross-section of the heat exchanger. In this way the effect on pressure drop caused by the gates can be minimized. Evaporator Heigth [m] Table3 Main characteristics of evaporators design.

The proposed system requires an investment of about 10,000 and has a payback of 5 years. 8. Conclusions The main conclusions from this study are as follows: The strategy of control of the RC involved the development of evaporators of changeable geometry for the hot sources and a condenser with variablebypass of the refrigeration fluid. The study showed that ethanol is the more suitable fluid, working the RC with a pressure of evaporation of 49 bar, a pressure of condensation of 2.3 bar, a temperature of superheating of 240 ºC and a thermal efficiency of 13.75%. The restrictions of volume of the evaporators and, therefore, the efficiency of exchange, and the remaining design restrictions lead to an optimized EGR cooling temperature of 120 ºC and to an optimized cooling temperature of the exhaust gases between 110 ºC and 230 ºC, in accordance with the ICE regime. A heat exchanger with finned tubes and continuous fins for evaporators was chosen. A concept of variable geometry was developed for blocking the flow of the hot gases upstream and downstream of the bank of tubes. The variable locking is made with two gates which allow a different number of channels of the bank of finned tubes. This way it is possible to artificially vary the swap area and the convection coefficient of the gases, thereby controlling the effectiveness of the evaporators. The evaporator designed to recover heat from the EGR is placed on the original location of the EGR cooler and the evaporator designed to recover heat from the exhaust gases replaces the original muffler of the vehicle. The heat exchangerselected for the condenser has concentric tubes with axial flow and is positioned vertically on the rear wall of the cab. 9
10 The proposed system achieves a reduction of fuel consumption and CO2 emissions of 5.5% in most of the ICE regimes and 6.6% at high speed. The mechanical power increases by about 6% in most of the ICE regimes and 7% at high speed. The proposed system requires an investment of about 10,000 and has payback of 5 years. 9.
