Alternative fuels and ecological aspects of motor vehicle engines

Vojnotehnički Glasnik, 1997
In the last two decades the world has faced two serious problems: the sources of liquid fuels are limited and the number of their users has intensified the problem of their toxicity. The researchers in this field face on extremely complex task: to find a

Impact of Alternative Paraffinic Fuels on the Durability of a Modern Common Rail Injection System

Energies, 2020
Common rail (CR) diesel fuel injection systems are very sensitive to variations in fuel properties, thus the impact of alternative fuels on the durability of the injection system should be investigated when considering the use of alternative fuels.

Integrating properties and conditions to predict spray performance of alternative aviation fuel by ANN model

Biotechnology for Biofuels and Bioproducts, 2023
Alternative aviation fuel has been confirmed benefits for GHGs reduction and energy saving. Alternative fuel use should meet drop-in fuel requirement, and one of the important factors to ensure combustion completeness is to achieve spray requirement in ...

Integrated Onboard Carbon Dioxide Capture and Liquefaction System for Dual-Fuel Marine Engines

Journal of Marine Science and Engineering
Onboard carbon capture and storage (OCCS) is promising, but downstream CO2 conditioning and liquefaction dominate energy and operability constraints. An integrated OCCS onboard for CO2 conditioning, deep cooling, phase separation and liquid CO2 (LCO2 ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

CFD Simulation of Pre-Chamber Spark-Ignition Engines—A Perspective Review

Energies
The growing demand to reduce emissions of pollutants and CO2 from internal combustion engines has led to a critical need for the development of ultra-lean burn engines that can maintain combustion stability while mitigating the risk of knock.

Fischer-Tropsch Diesel and Biofuels Exergy and Energy Analysis for Low Emissions Vehicles

Applied Sciences, 2021
This research investigates the effects of a synthetic diesel-like fuel (Fischer-Tropsch diesel) and biofuels (ethanol and biodiesel) fuel blends on the energy-exergy efficiencies and gaseous exhaust emissions characteristics of a compression ignition ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

What’s in my fuel tank? Insights into beliefs and preferences for e-fuels and biofuels

Energy, Sustainability and Society, 2023
Background Alternative fuels made from biomass or CO2 and water using renewable energy can reduce CO2 and pollutant emissions compared to fossil-based mobility and thus support a transition to a more sustainable transport.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability.
