Basic Investigation of Thermodynamic Effects on a Hydrogen Two-Stroke Engine

2024-32-003904/18/2025

The spark ignited two-stroke engine, as a cost-efficient power unit with low maintenance demand, is used millionfold for the propulsion of hand-held application, motorcycles, scooters, boats and others. The outstanding power to weight ratio is the key advantage for two-stroke engines. However, poor exhaust emissions, caused by high scavenge losses, especially on port controlled two-stroke engines, and a low efficiency are disadvantages of this combustion process. Under the aspect of increasing environment- and health awareness, the two-stroke technology driven with fossil resources, shows no future advantage. The anthropogenic climate change force for sustainable development of combustion engines whereby reduction of fuel consumption or usage of alternative fuels is an important factor. Best way of a decarbonization to fulfil future climate goals is the utilization of non-carbon fuels. In this field of fuels, hydrogen, with its high energy content and close inexhaustible availability

A Power Split eCVT Hybrid for Sustainable Urban Mobility

2024-32-002904/18/2025

The main drivers for powertrain electrification of two-wheelers, motorcycles and ATVs are increasingly stringent emission and noise limitations as well as the upcoming demand for carbon neutrality. Two-wheeler applications face significantly different constraints, such as packaging and mass targets, limited charging infrastructure in urban areas and demanding cost targets. Battery electric two wheelers are the optimal choice for transient city driving with limited range requirements. Hybridization provides considerable advantages and extended operation limits. Beside efficiency improvement, silent and zero emission modes with solutions allowing fully electric driving, combined boosting enhances performance and transient response. In general, there are two different two-wheeler base categories for hybrid powertrains: motorcycles featuring frame-integrated internal combustion engine (ICE) and transmission units, coupled with secondary drives via chain or belt; and scooters equipped with

MOLD IN COLOR PIANNO BLACK PC MATERIAL FOR AUTOMOTIVE EXTERIOR APPLICATION

2021-26-024209/22/2021

Aesthetics contribute significantly to the customer buying decision of an automobile. This is traditionally achieved through painting. Sustainability and cost challenges have led automakers to look at substituting painting through molded-in color polymers in decorative bezels like pillar appliques. These appliques and bezels have a unique mix of material requirements that include color tone, gloss, stiffness, scratch resistance and weathering. Polycarbonates are an interesting class of polymers that has potential to meet these challenging requirements. This paper reports the work done in evaluating a polycarbonate compound in piano black shade to meet the functional and aesthetic requirements. The results prove that the material can substitute painting thereby resulting in significant cost savings.

3D Printing with Wood-Based Ink

TBMG-3847402/01/2021

The way in which wood grows is controlled by its genetic code, which gives it unique properties in terms of porosity, toughness, and torsional strength. But wood has limitations when it comes to processing. Unlike metals and plastics, it cannot be melted and easily reshaped, and instead must be sawed, planed, or curved. Processes that involve conversion — to make products such as paper, cards, and textiles — destroy the underlying ultrastructure, or architecture, of the wood cells.

A Full-System Approach to Maximize Energy Efficiency of a Wheel Bearing

2020-01-163110/05/2020

Environmental sustainability is morphing Automotive technical development strategies and driving the evolution of vehicles with a speed and a strength hardly foreseeable a decade ago. The entire vehicle architecture is impacted, and energy efficiency becomes one of the most important parameters to reach goals, which are now not only market demands, but also based on regulatory standards with penalty consequences. Therefore, rolling drag from all bearings in multiple rotating parts of the vehicle needs to be reduced; wheel bearings are among the biggest in size regardless of the powertrain architecture (ICE, Hybrid, BEV) and have a significant impact. The design of wheel bearings is a complex balance between features influencing durability, robustness, vehicle dynamics, and, of course, energy efficiency. Whereas the driving efficiency and durability have always been main drivers for wheel hub designs, the upcoming development of BEVs, which use large battery packs, has introduced

Ford envisions broad portfolio of renewable materials - including coffee

20AUTP10_1010/01/2020

A broad portfolio of renewable materials is available now that can help the automotive industry reduce its carbon footprint. Many of these new materials exceed the performance of traditional plastic composites, and more are constantly coming online. This was the message from Dr. Deborah Mielewski, senior technical leader of sustainable and advanced materials at Ford, during her recent “Greener materials for a greener world” virtual keynote at the 2020 SPE Automotive Composites Conference. According to Mielewski, Ford already has more than 10 renewable materials in production, including natural fiber reinforced composites such as wheat straw, rice hulls and tree-based cellulose fiber that exceed traditional-material performance. “Over the past five years, we have kicked off several new material investigations with cellulose nanofibers and materials from carbon dioxide,” Mielewski said, “and we are applying our knowledge in green materials to the exploding area of 3D printing.”

A Material Flow Model for Production Stage for a Life Cycle of Passenger Cars with Combustion Engine and Electric Powertrain

2020-01-202009/15/2020

To meet the requirements of sustainable development, car environmental impacts must be assessed at all stages of its life: from designing, through its manufacture and use, to its recycling after use. Life-cycle assessment (LCA) makes it possible. This approach to environmental assessment is necessary, particularly in assessment of new technologies of electric powertrain, where most environmental impacts are shifted from the use stage to production. Reliable and possibly the most recent data are required on materials and production processes to develop a valid flow model. Ecoinvent inventory database is a commonly used source of reliable data. However, Ecoinvent provides data about Golf 4 (1,240 kg), a compact class car. The ratio of glider and drivetrain is therefore optimized for that class. Using the dataset for other vehicle classes by simply considerably increasing or decreasing the total vehicle mass may lead to imprecise results. There is no mathematical relationship that would

Effect of Renewable Fuel Blends on PN and SPN Emissions in a GDI Engine

2020-01-219909/15/2020

To characterize the effects of renewable fuels on particulate emissions from GDI engines, engine experiments were conducted using EN228-compliant gasoline fuel blends containing no oxygenates, 10% ethanol (EtOH), or 22% ethyl tert-butyl ether (ETBE). The experiments were conducted in a single cylinder GDI engine using a 6-hole fuel injector operated at 200 bar injection pressure. Both PN in raw exhaust and solid PN (SPN) were measured at two load points and various start of injection (SOI) timings. Raw PN and SPN results were classified into various size ranges, corresponding to current and future legislations. At early SOI timings, where particulate formation is dominated by diffusion flames on the piston due to liquid film, the oxygenated blends yielded dramatically higher PN and SPN emissions than reference gasoline because of fuel effects. For particulates >23 nm and with optimized SOI timing, the use of oxygenated blends significantly increases SPN and conversely decreases raw PN

Smart Sponge for Environmental Remediation

TBMG-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.

Chromium Removal from PVC Filters

TBMG-3578701/01/2020

Chromium metals and hexavalent chromium are known health hazards monitored in workplace environments. Occupational health professionals use polyvinyl chloride (PVC) in disc filters to monitor total chromium present in a workplace. If chromium background is present in the filters, the interpretation of the results can be problematic. Current analytical analysis methods can't discern environmentally harvested chromium materials from chromium that is present as a result of manufacturing byproducts in the filters. A need exists for a non-destructive method of removing the background concentration of chromium metals and hexavalent chromium that is present in the PVC filters.

Process Turns Sand and Plant Materials into a Water Filtration Tool

TBMG-3581901/01/2020

According to the United Nations, 2.1 billion people lack access to safely managed drinking water services and the majority live in developing nations. A process was developed that uses sand and plant materials readily available in many developing nations to create a cheap and effective water filtration medium called “f-sand.” F-sand uses proteins from the Moringa oleifera plant, a tree native to India that grows well in tropical and subtropical climates. The tree is cultivated for food and natural oils, and the seeds are already used for a type of rudimentary water purification; however, this traditional means of purification leaves behind high amounts of dissolved organic carbon (DOC) from the seeds, allowing bacteria to regrow after just 24 hours. This leaves only a short window in which the water is drinkable.

Reducing winter range loss for electric trucks

19TOFHP12_0212/01/2019

Researchers at the Austrian Institute of Technology have developed an air exchange system that's capable of reducing heat load by 37% in real-world tests. Battery-electric vehicle (BEV) range loss from winter use of PTC (positive temperature coefficient) heating has become a source of major concern as the industry works to make EVs a mainstream choice. Addressing this particular problem area with an economically viable solution was deemed a worthwhile effort by the Austrian Institute of Technology (AIT), which is jointly owned by the Austrian government and the Federation of Austrian Industries. A fleet test of electric delivery trucks is underway on European roads. The AIT project, results of which were presented at the recent SAE Thermal Management Systems Symposium (TMSS), began by noting a 20% loss in range at −15°C (+5°F) from the heating system. AIT set a target of recovering 25% of that loss, primarily with the use of a ventilation module. Available reference data (at −10°C/+14
