Rear Wiper Motor with Nozzle Integration for Improved wiping performance and Perceived Quality2026-26-0600To be published on 01/16/2026
In the current modern days of driving, rear wiping performance plays a crucial role in safe driving. This study focuses on improving the rear wiping with add on benefits like improved BSR performance, cost saving and perceived quality. This new concept has the rear wiper motor assembly which accommodates the nozzle also thereby making it a single unified assembly with reduced system complexity. This concept eliminates the complex hose routing of washer system for rear wiping which is usually packaged at spoiler or HMSL. It also helps in improved spray coverage and reduced dry wiping which in turn enhances system reliability with clean & quiet operation. This integrated nozzle concept is much more compact than the available products in the market with minimum number of end items. Also, this design comes with non-return valve which ensures there is no delay in the spray execution. And it improves the cleaning efficiency by maintaining consistent fluid pressure. This concept comes with

Acoustic Evaluation of Fiber Based Materials for Engine Bay Applications2025-01-011505/05/2023
A newly formulated fiber-based material was developed to offer a cleaner, recyclable alternative to foam-based vehicle acoustic products. The fiber-based material was designed to be used in multiple vehicle acoustic applications, with different blends of the material available depending on the application. It performs well as an engine bay sound absorber due to its high heat tolerance and good absorption performance. A study was conducted to evaluate the sound absorption performance of this fiber-based material, specifically the engine bay blends, in comparison to that of current foam-based products. The results from this study show that the sound absorption performance of this new fiber-based material can match that of current foam-based materials while providing a recyclable product unlike the foam.

An Effective Design of Micro Tesla Valve as a Passive Mixer in Microfluidics Channels 2022-26-117805/26/2022
Mixing fluids is one of the major challenges in microfluidics. Normally, the mixing process is done by diffusion rather than turbulence, which makes it very slow due to low Reynolds number (Re) flow in the range of 0.1 to1. Owing to this behaviour, ineffective mixing occurs when two miscible liquids are mixed purely by diffusion which requires longer striation lengths and therefore longer microfluidic channels along with lengthy mixing time. Homogeneous mixing of solute and solvent is important for providing consistent chemical and biological reactions in µTAS.In this study, we develop a passive mixer that provides efficient mixing using micro tesla valves which allows the flow of liquids in the forward and reverse directions to analyse the formed vortices, turbulent intense areas, Reynolds number, and pressure using Ansys fluent workbench. An optimum design has been arrived by varying the number of cells from 1 to 5 in series and realization is done by excimer laser micromachining.

Bacteria-Based Hydrogel Beads Clean Up Contaminated GroundwaterTBMG-3745108/01/2020
Hydrogel beads with the consistency of gummy candy are made with an ingredient used in processed foods to clean up groundwater contaminated with dangerous and widely used volatile organic compounds (VOCs). Among the contaminants addressed by the method are 1,1,1-trichloroethane, cis-1,2-dichloroethene, and 1,4-dioxane — degreasers commonly used by industry and the military. The chemicals can infiltrate groundwater through leaky underground storage tanks or runoff, or by simply being dumped on the ground.
Smart Sponge for Environmental RemediationTBMG-3744108/01/2020
Oil spill cleanup is an expensive and complicated process that often harms marine life and further damages the environment. Currently used solutions include burning the oil, using chemical dispersants to breakdown oil into very small droplets, skimming oil floating on top of water, and/or absorbing it with expensive, unrecyclable sorbents. Burning increases carbon emissions and dispersants are harmful for marine wildlife. Skimmers don’t work in rough waters or with thin layers of oil. Sorbents are not only expensive but generate a huge amount of physical waste.
EDITORIAL: ConExpo excels amid COVID-1920TOFHP04_0504/01/2020
Las Vegas seemed to be in a bubble from March 10-13, the week of ConExpo-Con/Agg & IFPE 2020. Tens of thousands of attendees crowded the halls inside the Las Vegas Convention Center and outside on the new Festival Grounds lot. Business was being conducted and news was being made. Evidence of that is in SAE Truck & Off-Highway Engineering's extensive coverage of new machines and technology unveiled at the event that appears in these pages and online at www.sae.org. But a steady stream of news alerts and near-constant chatter about the quickly shifting Coronavirus pandemic in the U.S. and elsewhere reminded show-goers that not all was business as usual. An abundance of hand-sanitizing stations and red anti-handshaking buttons stating “No offense, just makes sense” also got the point across.

Parameter Sensitivity and Process Time Reduction for Friction Element Welding of 6061-T6 Aluminum to 1500 MPa Press-Hardened Steel05-12-01-000412/14/2018
Conventional fusion joining techniques pervasive in the automotive industry are unable to effectively join aluminum and steel. To solve this problem, a technique termed friction element welding (FEW) has been developed, which is able to join any nonferrous top sheet material to a base steel layer, independent of the base layer strength. FEW works on the same principles as friction welding, as a steel element is pushed and rotated against a nonferrous top sheet to create frictional energy which softens and flows the material around the fastener shaft and under the fastener head, exposing the steel below. The element then contacts the steel and bonds through traditional friction welding. FEW is a four-step process (penetration, cleaning, welding, compression), with two to four parameters (endload, spindle speed, displacement transition, time transition) controlling each step. This research examines the parameter sensitivity of the FEW process in the cleaning, welding, and compression

Fabrication of BSA 14-23 Superhydrophobic Sponges as Efficient Oil and Organic Liquid AbsorbentsTBMG-2702706/01/2017
Oil spills have become an environmental problem due to the growth of offshore oil exploration, production, and transportation. There are several methods that have been used to clean up oil spills such as chemical dispersants, water skimming, and using absorbent materials. Although skimming is the most common method for cleaning large spills, this method is time-consuming, expensive, and poorly separates oil and water. Chemical dispersants can be used to break up oil slicks into droplets that can be easily dissipated in water, but the mixture of oil and dispersants can be toxic and damage marine ecosystems. Thus, the use of oil sorbents can be an effective method to ease oil collection, and sorbents have a high capacity for removing oil from a targeted site.
Automotive A/C Servicing – Refrigerant Flushing of a Failed A/C System2017-01-016703/28/2017
The failure of an A/C system often results in the introduction of contaminants to the A/C system. The sources of the contaminants include debris from damaged components and debris from the surrounding environment. Returning the A/C system to service requires the removal of these contaminants from any reused components. The recommended approach to cleaning contaminated components and systems is to flush with a solvent flushing machine. Previous internal studies have concluded that solvent flushing will remove all contaminants, restoring component and system performance. Many commercial refrigerant recovery and recharge machines include a refrigerant “flush” feature which can flush oil from the system and components with the systems refrigerant. The effectiveness of using the “flush” feature of a refrigerant recovery and recharge machine with an added in-line filter to remove contaminants is investigated. One gram of Arizona Test Dust is introduced to the suction line of an automotive A

System for In-Situ Detection of Plant Exposure to Trichloroethylene (TCE)TBMG-2618801/01/2017
In collaboration with the State University of New York and the Naval Research Laboratory, NASA’s Marshall Space Flight Center is developing a hyperspectral estimator to detect trichloroethylene (TCE) in plants. TCE has been a widely used industrial solvent known to be toxic to humans and animals. Although its use and disposal have become more restricted in recent years, TCE is one of the more prevalent groundwater contaminants in the United States. Current methods exist to identify the locations of TCE at contaminated sites; however, these methods typically require destructive sampling techniques as well as time-consuming and expensive laboratory analysis. In contrast, the hyperspectral estimator is being designed as a nondestructive, quick, and lower-cost way to screen for TCE across large areas. It works by using spectral signatures to determine the presence/absence of TCE in the leaves of plants that may have absorbed the contaminant from surrounding groundwater.

Microwave-Steam Based Road Deicing Vehicle Focused on Thin Ice Layers2015-01-050204/14/2015
For the thin ice on the road in winter, the traditional road deicing vehicle relies on mechanical and chemical methods for melting ice, which is inclined to damage the pavement and has insidious influence on environment. The thermal deicing vehicle has been adopted in recent years. Although the deicing method is available, the deicing efficiency is unacceptable while the energy consumption is huge. The study adopts the new idea of “bottom-to-top” for melting the intersection area between the road surface and the bottom ice layer by the microwave heating firstly and then cleaning them out using high pres. vapor cutting so as to save the cost of energy and enhance the traffic safety. First of all, the mathematical model of the melting process of the intersection of the pavement and the ice layer was established according to the microwave heating characteristics. Then the mechanism about the compatibility between the steam temperature, saturation and the upper surface of the ice was

Laser Profilometry For Non-Contact Automated Countersink Diameter Measurement2014-01-225509/16/2014
Automated countersink measurement methods which require contact with the workpiece are susceptible to a loss of accuracy due to cutting debris and lube build-up. This paper demonstrates a non-contact method for countersink diameter measurement on CFRP which eliminates the need for periodic cleaning. Holes are scanned in process using a laser profilometer. Coordinates for points along the countersink edge are processed with a unique filtering algorithm providing a highly repeatable estimate for major and minor diameter.

Vacuum Cleaning Vehicle Dust Subsidence System Design2014-01-075004/01/2014
Vacuum cleaning vehicle is the necessary equipment for the Municipal Sanitation Department to keep the road surface clean and the dust subsidence system is the heart unit for the proper function of the cleaning vehicle. The reasonable design of this system could increase the load capacity of the vehicle and be convenient for the garbage collecting and dumping. Meanwhile, the engine power could be relatively reduced and the influence on the environment duo to the dusty air in the outlet could be also effectively improved. In the study, the gravity dedusting principle is used firstly for structure design to reduce the flow rate of dust particles inside the lower part of the dust subsidence system. The ruleless collision loss among dust particles is reduced and thereby the fan power is saved. By means of a reasonable separated chamber design and the use of inertia baffle, the sort management for dust particles is developed and the work stress of the export filter is released observably

Improved Cyclic Performances of Li-Sulfur Batteries with Sulfone-Based Electrolyte2014-01-184404/01/2014
The effects of electrolyte on the cyclability of Li/S battery were investigated in this work. The electrochemical properties of single component ether solvents and a binary mixture of ether solvents were studied. These ether-based electrolytes have polysulfide shuttle problems which result in severe low Coulombic efficiency. To overcome these issues, sulfone-based solvent which forms a stable passivation film at the anode surface were used. As a result, the proper composition of sulfone-based electrolyte were obtained. Its capacity and reversible capacity retention were improved to 715 mAh/g and 72.6% which were increased by 52.1% and 63.1%, respectively, compared to those of ether-based electrolyte.

Fatigue Behavior of Stainless Steel Sheet Specimens at Extremely High Temperatures2014-01-097504/01/2014
Active regeneration systems for cleaning diesel exhaust can operate at extremely high temperatures up to 1000°C. The extremely high temperatures create a unique challenge for the design of regeneration structural components near their melting temperatures. In this paper, the preparation of the sheet specimens and the test set-up based on induction heating for sheet specimens are first presented. Tensile test data at room temperature, 500, 700, 900 and 1100°C are then presented. The yield strength and tensile strength were observed to decrease with decreasing strain rate in tests conducted at 900 and 1100°C but no strain rate dependence was observed in the elastic properties for tests conducted below 900°C. The stress-life relations for under cyclic loading at 700 and 1100°C with and without hold time are then investigated. The fatigue test data show that the hold time at the maximum stress strongly affects the stress-life relation at high temperatures. When the results are plotted as

A Need for Processes that Future Proof the Fiber Optic Installation2013-01-218109/17/2013
The tenets of IEC 61300-3-35 have influenced and contributed to numerous standards. These include: a.) the importance of cleaning the fiber optic connection, b.) the concept of diameter of debris or contamination, and, c.) the area of the end face to be cleaned, d.) methods of cleaning. As capacity and bandwidth expand, deployments updated, and new technicians trained, a clear understanding of several other tenets of precision cleaning the connection may also be considered. There are many types of debris and contamination. Some are dry Figure-1 and others are fluidic Figure-2. Debris on an end face may also be present in combination Figure-3. The cleaning procedure should strive to be a first time event. A best practice procedure can be identified that does not require multiple techniques and numerous attempts.

Non-Thermal Particulate Filter Regeneration Using Rapid Pulse Electric Discharges2013-01-051804/08/2013
This research introduces a new, novel approach to reverse flow particulate filter regeneration enabled by rapidly pulsed electric discharges. The discharges physically dislodge particulate matter (PM) from the filter substrate and allow a very low reverse air flow to transport it to a soot handling system. The system is operable independent of filter temperature, does not expose the filter to high thermal stresses or temperatures, has no apparent upper limit for filter PM-mass level (regeneration of a filter up to 17 g/L has been demonstrated), and does not require any catalyst. The system is inherently scalable allowing application to monolithic filters of any size or shape and can be tailored to suit specific application requirements such as limits on maximum regeneration time or power consumption. For example a light duty application would require as little as 200-500W electrical power to regenerate a filter in less than ten minutes (i.e. passenger car GPF or DPF). The paper

Major Breakthrough in Multi Material Drilling, Using Low Frequency Axial Vibration Assistance2012-01-186609/10/2012
Aircraft design has mainly changed in the past years, introducing new materials such as CFRP at a large scale. Even if this great change brought many advantages: weight, sustainability, reliability… it upset the way to produce basic parts and to assembly. A special difficulty lies in drilling multiple stacks made of different materials, i.e. metal (aluminum, titanium, stainless steel) + CFPR. Indeed, as the process has to drill through those stacks during a unique operation, cutting conditions and tool technologies are a compromise. As a consequence, tool life cycle, productivity and above all, hole quality are no longer optimum. Some materials, such as titanium requires low cutting speed and high feed rate whereas CFRP requires opposite trends. Moreover, heat generated by cutting metal (especially titanium) can damage CFRP when overheated metallic chips pass through. Finally, the compromise for cutting conditions and tool technology can generate long metallic chips that may congest
