Design of a Hydraulic Control Unit for a Two-Speed Dedicated Electric Vehicle Transmission Xiangyang Xu, Wenbo Sun, Tianyuan Cai, Yanfang Liu, Xiao Han |
||
| Two-speed automatic transmission is one solution to increasing the economic efficiency and dynamic performance of battery electric vehicles (BEVs). The hydraulic control unit (HCU) is a key component in automatic transmissions, and directly determines the quality of shifting. In this paper, we propose a design for a 2DET hydraulic control unit based on the structural scheme and shift logic of a two-speed dedicated electric vehicle transmission (2DET) with two wet clutches. The system is composed of three subsystems: an oil pressure regulating and flow control system, a shift operation and control system and a cooling and lubrication system. The results of our experiments, including the valve body bench tests, transmission bench tests and vehicle test, show that our design for a hydraulic control unit meets the requirements. | |||

Impacts of Vessel and Injected Water Temperatures on Direct Water Injection in Internal Combustion Rankine Cycle Engines Jingtao Wu, Zhe Kang, Zhehao Zhang, Zhilong Li, Jun Deng, Zhijun Wu |
||
| This study focused on the effects of vessel and injection temperatures on direct water injection in internal combustion Rankine cycle engines through experimental and numerical methods. First, a study was carried out with schlieren photography using a high-speed camera for simultaneous liquid-gas diagnoses. Water was directly injected into a constant-volume vessel that provided stable boundaries. We wrote a Matlab program to calculate spray tip penetration and cone angle from the images. For the further extension of boundary conditions, a numerical model was established and calibrated in AVL-FIRE for the thorough analysis of injection characteristics. Both experimental and numerical results indicated that injection and vessel temperatures have different effects on spray tip penetration. An increase in injected water temperature leads to shorter spray tip penetration, while the spray tip penetration increases with increasing vessel temperature. However, increased injection and vessel temperatures can both decrease the spray cone angle. Moreover, the simulation results also suggested that heat conduction is a main factor in boosting evaporation under top dead center conditions. When the internal energy of water parcels surges, these parcels evaporate immediately. These results are helpful and crucial for internal combustion engines equipped with direct water injection technology. | |||

Design of a Regenerative Auxiliary Power System for Service Vehicles Yanjun Huang, Milad Khazraee, Hong Wang, Soheil M. Fard, Tianjun Zhu, Amir Khajepour |
||
| This paper presents a RAPS, namely the regenerative auxiliary power system, for the vehicle with special accessory power systems. Taking city buses and delivery trucks as examples, service vehicles keep engines idling to power their auxiliary devices (e.g., refrigeration systems and hydraulic pumps). The potential fuel savings brought on by the electrification of these auxiliary systems are first quantitatively analyzed over a typical drive cycle for a delivery truck. The RAPS is then designed, and its components are sized in accordance with the objectives of compactness and cost-effectiveness. By introducing the proposed RAPS into a conventional delivery truck with an internal combustion engine, the powertrain can be treated as a hybrid because of adding an extra battery. As a result, to pursue a high overall efficiency, a holistic controller is presented for determining how and when to recharge the battery while minimizing the auxiliary system’s power consumption. More importantly, the proposed RAPS saves about 7% fuel when compared with consumption by conventional service vehicles. | |||

A Two-Level Cross-Sectional Optimization Approach for Automotive Body Concept Design Huan Qin , Zijian Liu , Yu Liu , Haolong Zhong |
||
| Concept design is vital important in development of auto-body and it has great effects on later design work. In this paper, a two-level cross-sectional optimization approach is presented to shorten concept design cycles. First, an exact structural analysis approach for spatial semi-rigid framed structures, i.e., the transfer stiffness matrix method proposed in our previous study, is adopted for both static and dynamic analyses of body-in-white (BIW) structure. A two-level cross-sectional optimization approach is then proposed for an automotive BIW lightweight design, and genetic algorithm is used to solve the optimization models. Afterward, an object-oriented MATLAB toolbox, using distributed parallel computing techniques, is developed to promote the concept design of the BIW structure. Finally, relevant numerical examples demonstrate the validity and accuracy of the proposed method. | |||
