1 A Study of EGR Stratification in an Engine Cylinder Bassem Ramadan Kettering University ABSTRACT One strategy to decrease the amount of oxides of nitrogen formed and emitted from certain combustion devices, such as the internal combustion engine, is to recirculate and introduce a portion of the unburned product gases with the air and fuel. The effect of the re-circulated gases is to decrease the maximum temperatures in the flame zone, and hence decrease NOx formation. However, dilution of the air-fuel mixture in an engine using stratified EGR could offer significant fuel economy saving comparable to lean burn or stratified charge direct-injection SI engines. The most critical challenge is to keep the EGR and air-fuel mixture separated, or to minimize the mixing between the two zones to an acceptable level for stable and complete combustion. Swirl-type stratified EGR and fuel-air flow structure is considered desirable for this purpose, because the circular shape of the cylinder tends to preserve the swirl motion. Moreover, the axial piston motion has minimal effect on the swirling motion of the fluid in the cylinder. In this study, we consider intake system design in order to generate a two-zone combustion system, where EGR is maintained in a layer on the periphery of the cylinder, and the fuelair mixture is maintained in the center of the cylinder. KIVA-3V was used to perform numerical simulations on an engine with a central intake and peripheral EGR ports. The simulations were performed to determine if the twozones can be generated in the cylinder, and to what extent mixing between the two zones occurs. For the engine geometry used in this study, the results showed that it is possible to generate the two zones, but mixing is difficult to control. INTRODUCTION A number of advanced systems have been explored and developed to improve fuel economy of SI engines at part load. Some of these systems include, directinjection stratified charge, lean burn, variable compression ratio, variable valve timing and lift, and hybrid. In a two-zone combustion system, the engine cylinder is divided into two zones: one contains EGR only, and the other one contains air-fuel only [1]. The volume of the air-fuel zone is determined according to the required engine load. The volume of the EGR is to occupy the rest of the cylinder to reduce pumping losses. Depending on the engine application, the cylinder could be divided into two zones, a top air zone, and an EGR zone at the bottom [1]. This configuration is referred to as axial stratification. Another configuration, involves intake side air and exhaust side EGR, this is referred to as lateral stratification [2,3]. The third method is to introduce air centrally and EGR on the outer periphery of the cylinder radial stratification [4,5]. The challenging task in these systems is how to generate stratification during the intake, and how to maintain the stratification during the compression stroke prior to ignition [1]. In axial stratification, it is difficult to

2 maintain stratification during compression, because the bottom zone is compressed by the moving piston and hence, mixing between EGR and air is inevitable [1]. Lateral EGR stratification is often accompanied by strong incylinder tumble motion. During the late stages of the compression stroke, the coherent tumble flow structures tend to collapse due to the moving piston. Radial EGR stratification seems to be the most promising way to generate and maintain stratification in the cylinder [1]. The central air-fuel cylinder and the outer EGR tubular cylinder are concentric with the engine cylinder. As the piston moves upward, both zones get compressed in the axial direction. In addition, if both the EGR and the air-fuel are swirling in the same direction, stratification can be sustained much longer towards the end of the compression stroke [1]. The goal is to create an outer EGR layer, and an inner air layer as shown in Figure 1. Air -Fuel EGR Figure 1. Schematic depicting radial stratification. In this study, different intake and EGR systems were considered to determine if radial stratification could be generated during the intake stroke with both EGR and air-fuel mixture swirling in the same direction. The study also, determines if stratification can be maintained during the later stages of the compression stroke. However, the effect of EGR stratification on combustion was not considered in this study. In a previous study [1], the effect of stratification on combustion was investigated. However, EGR stratification was artificially created. This study, considers the design of intake systems to generate EGR stratification. ENGINE GEOMETRY The engine geometry considered in this study is shown in Figure 2. The engine had a single centrally located intake helical port. The helical intake port was designed to impart a swirling motion to the inducted air. Ports located near the periphery of the cylinder were used to introduce EGR to the cylinder. Two and then four EGR ports were used. The ports used were designed to help generate swirl with the EGR. Different valve timings were used for both the intake and EGR valves in order to optimize EGR stratification. Valve lifts were also varied for the same reason. Moreover, the sizes of the EGR ports were varied to improve stratification. The engine parameters used in this study are listed in Table 1. Table 1. Engine parameters used. Parameter Value Bore 100 mm Stroke 95.5 mm Squish 1.0 mm Engine RPM 2000 Intake/EGR Valve Opening 4 degrees ATDC Intake/EGR Valve Closing 25 degrees ABDC NUMERICAL MODELING The computer code KIVA-3V [6] was used to perform the numerical simulation. The simulations were started at the beginning of the intake stroke. The

3 simulations were performed through the intake and compression strokes only. No fuel was injected or mixed with the fresh air since combustion was not modeled in this study. The code was modified in order to use shrouded valves in the EGR ports. The simulation results from a previous study [7] showed that using shrouded valves in intake ports helps generate swirl. Side View Top View ports located on the periphery of the cylinder. Moreover, if both the EGR and the air-fuel mixture are swirling in the same direction, stratification can be sustained much longer towards the end of the compression stroke. Hence, two opposing EGR ports were used in order to generate swirl, and a helical intake system was used to impart a swirling motion to the incoming air. Several different intake valve and EGR valve timings were considered. After several iterations, it was determined that complete EGR stratification (inner layer contains only air, and outer layer contains only EGR) was not achieved at the end of the intake stroke. Figure 3 shows the air mass fraction contours plotted in a horizontal plane (perpendicular to cylinder axis) near BDC. The results indicate that mixing between the two layers occurred. The maximum concentration of air in the center was 60%, and the maximum EGR concentration near the cylinder walls was also 60%. Figure 4 shows that both layers eventually were swirling in the same direction. Figure 2. Engine geometry used showing central helical intake and two EGR ports. The EGR ports used in this study were modeled as intake ports, with EGR flowing through them. The central intake port had air flowing through it. Several engine parameters were varied in order to determine the best strategy or configuration to achieve stratification in the cylinder. Since, the goal is to maintain air in the center of the cylinder, and EGR in an outer layer, a centrally located intake valve was used, and EGR Figure 3. Air mass fraction contours plotted in a horizontal plane at BDC. The results shown in Figure 6, with the two EGR ports, showed that swirl was not achieved until late during the intake stroke. Moreover, entrainment of air by EGR flow also occurred. Hence, using

4 two additional EGR ports could accelerate swirl generation, and could prevent entrainment. In order to determine if EGR stratification could be improved using the same engine, two additional EGR ports were used, as shown in Figure 7. Figure 4. Velocity vectors plotted in a horizontal plane show swirl motion at BDC. In order to determine when EGR stratification occurred during the intake stroke, velocity vectors and air mass fraction contours were plotted at various crank angles. The results shown in Figures 5 and 6 indicate that swirl was almost completely developed in the cylinder 70 degrees CA ATDC. Figure 7. Engine geometry used with central helical intake and four EGR ports. The results shown in Figures 8 and 9, indicate that swirl did develop earlier during the intake stroke, and EGR stratification was more evident. Figure 5. Air mass fraction contours shown at 70 degrees crank angle ATDC. Figure 8. Air mass fraction contours shown at 40 degrees crank angle ATDC, (4EGR ports). Figure 6. Velocity vectors plotted at 70 degrees crank angle ATDC. Figure 9. Velocity vectors plotted at 40 degrees crank angle ATDC, (4EGR ports).

5 The results for this case were also plotted at BDC in order to compare with the case of the two EGR ports. Figures 10 and 11 show the mass fraction contours and velocity vectors at BDC. maintained through the compression stroke. In all of the above cases, EGR and air were completed mixed at the end of the compression stroke. Since, EGR stratification is required prior to ignition, more studies with combustion will be needed to determine if combustion will be possible. CONCLUSIONS From the above results the following conclusions can be drawn: Figure 10. Air mass fraction contours plotted at BDC, (4EGR ports). 1. The use of a helical intake valve with two EGR ports resulted in incomplete EGR stratification in the cylinder at the end of the intake stroke. 2. When four EGR ports were used with the helical intake system, EGR stratification was more evident in the cylinder at the end of the intake stroke. Figure 9. Velocity vectors plotted at BDC, (4EGR ports). The results shown in Figure 10 indicate that EGR stratification was not complete. Some EGR has diffused into the air layer, and air has diffused into the EGR layer. However, the maximum air concentration in the EGR layer was 10%. The maximum concentration of EGR in the air layer was 30%. This shows that separating EGR and air into two separate layers was not accomplished. However, considering that achieving complete stratification is may be impossible, the above results look promising. The next step in this study was to determine if EGR stratification could be 3. With four EGR ports swirl motion was generated earlier during the intake stroke, as compared to the swirl motion generated with two EGR ports. 4. In all cases EGR stratification could not be maintained in the cylinder late during the compression stroke. Additional studies with combustion are needed in order to determine the benefits, if any, of incomplete stratification. REFERENCES 1.
