An Optimal Energy Management Strategy For Hybrid Electric Vehicles, Amir Rezaei

Dissertations, Master's Theses and Master's Reports

Hybrid Electric Vehicles (HEVs) are used to overcome the short-range and long charging time problems of purely electric vehicles. HEVs have at least two power sources. Therefore, the Energy Management (EM) strategy for dividing the driver requested power between the available power sources plays an important role in achieving good HEV performance.

This work, proposes a novel real-time EM strategy for HEVs which is named ECMS-CESO. ECMS-CESO is based on the Equivalent Consumption Minimization Strategy (ECMS) and is designed to Catch Energy Saving Opportunities (CESO) while operating the vehicle. ECMS-CESO is an instantaneous optimal controller, i. e., it does not ...

Recently an after-treatment system called SCR catalyst on a DPF capable of simultaneously reducing both NOx and PM emissions has been developed in order to reduce the overall size of the after-treatment system.

The goal of this proposed research is to create a state estimator ...


Effect Of Spark Advance And Fuel On Knocking Tendency Of Spark Ignited Engine, Abhay S. Joshi 2017 Michigan Technological University

Effect Of Spark Advance And Fuel On Knocking Tendency Of Spark Ignited Engine, Abhay S. Joshi

Dissertations, Master's Theses and Master's Reports

Knock, in spark ignition engine is the combustion caused by the autoignition of the fuel-air mixture. It is the phenomenon that limits engine performance and thermal efficiency. Knock also has an adverse effect on emissions and fuel economy. Engine designers target engines with maximum power and torque output without compromising on fuel economy. Engine downsizing is the method generally adopted. The main goal of engine downsizing is to achieve better fuel economy while increasing the power and torque output of the engine. Better fuel economy is achieved by reducing the displaced volume which in turn means a much higher brake ...

Electronic Deer Warning System, David Zhuo, Anlang Lu 2016 California Polytechnic State University, San Luis Obispo

Electronic Deer Warning System, David Zhuo, Anlang Lu

Computer Engineering

Deer-vehicle collisions (DVCs) are extremely dangerous, often injuring or even killing drivers. Unfortunately, this form of automotive accident is commonplace in the United States. According to the NHTSA, DVCs result in 200 human deaths a year.2

Despite these deadly incidents, there currently are no deployed federal or state systems for preventing DVCs. There are many consumer electronic deer deterrent products, but their long-term effectiveness is questionable.3 In fact, there does not appear to be much research into electronic deer deterrent systems. Aside from constant audio output and electric shock, no other means of electronic deterrent exist. Even if ...

Papers & Publications: Interdisciplinary Journal of Undergraduate Research

The future of automotive engineering lies in intelligent vehicles. The combined effects of multiple intelligent sub-systems will provide drivers with essential feedback to increase driving safety and reduce fuel wasted in unnecessary acceleration and inefficient traffic routing. Discrete intelligent sub-systems have been increasingly incorporated into consumer vehicles for decades, and continue to evolve. The revolutionary next step in development is fully integrating intelligent capabilities into a total vehicle control system. This may be accomplished through a multilevel control architecture, starting with sensor fusion.

Fused sensors, such as LiDAR and RADAR, will provide their inputs to a single virtual model from ...


Investigation Of Low Reynolds Number Flow And Heat Transfer Of Louvered Surfaces, Pradeep R. Shinde 2016 Florida International University

Investigation Of Low Reynolds Number Flow And Heat Transfer Of Louvered Surfaces, Pradeep R. Shinde

FIU Electronic Theses and Dissertations

This study focuses on the investigation of flow behavior at low Reynolds numbers by the experimental and numerical performance testing of micro-channel heat exchangers. An experimental study of the heat transfers and pressure drop of compact heat exchangers with louvered fins and flat tubes was conducted within a low air-side Reynolds number range of 20 < ReLp < 225. Using an existing low-speed wind tunnel, 26 sample heat exchangers of corrugated louver fin type, were tested. New correlations for Colburn j and Fanning friction f factor have been developed in terms of non-dimensional parameters. Within the investigated parameter ranges, it seems that both the j and f factors are better represented by two correlations in two flow regimes (one for ReLp = 20 – 80 and one for ReLp = 80 – 200) than a single regime correlation in the power-law format. The results support the conclusion that airflow and heat transfer at very low Reynolds numbers behaves differently from that at higher Reynolds numbers ...
