B20 Fuel Compatibility with Steels in Case of Fuel Contamination
(MDPI, 11.08.2023)
articleThis study evaluated the compatibility with steels for three B20 fuel samples blended from fossil diesel and used cooking oil methyl ester. One sample was untreated and its concentration of copper was analyzed as <1 ppm. ... -
Combustion Studies of a Non-Road Diesel Engine with Several Alternative Liquid Fuels
(Molecular Diversity Preservation International (MDPI), 25.06.2019)
articleSustainable liquid fuels will be needed for decades to fulfil the world’s growing energy demands. Combustion systems must be able to operate with a variety of renewable and sustainable fuels. This study focused on how the ... -
Crude Tall Oil based Renewable Diesel: Performance, Emission Characteristics and Storage Stability
(SAE International, 21.09.2021)
articleInternational policies aiming at replacing fossil fuels with bio-components are getting stronger. Hydrotreating of bio-oils is a sustainable way to produce premium quality diesel fuels from completely renewable feedstocks. ... -
Effect of Alternative Liquid Fuels on the Exhaust Particle Size Distributions of a Medium-Speed Diesel Engine
(Molecular Diversity Preservation International (MDPI), 29.05.2019)
articleWe mainly aimed to determine how alternative liquid fuels affect the exhaust particle size distributions (PSD) emitted by a medium-speed diesel engine. The selected alternative fuels included: circulation-origin marine gas ... -
Effect of late diesel injection on close-coupled SCR + ASC during DPF regeneration period
(Elsevier, 14.10.2024)
articleFuture emission limits (Stage 6) for off-road engines will require more efficient removal of nitrogen oxides. The dual-SCR system has in addition of conventional main SCR catalyst after diesel oxidation catalyst (DOC) and ... -
Effects of alternative marine diesel fuels on the exhaust particle size distributions of an off-road diesel engine
(Elsevier, 05.03.2019)
articleThe main objective of this study was to find out how alternative fuels affect the exhaust gas particle size distribution. The fuels are later intended for marine applications. Along with low-sulfur marine light fuel oil ... -
Effects of Crude Tall Oil Based Renewable Diesel on the Performance and Emissions of a Non-Road Diesel Engine
(SAE International, 21.09.2021)
articleEnvironmental concerns and government policies aiming to increase biofuel shares have led to the search for alternative fuels from a variety of renewable raw materials. The development of hydrotreated vegetable oil (HVO) ... -
Exhaust particle number of a non-road diesel engine fuelled by methyl esters with different fatty acid compositions
(Estonian Agricultural University, Faculty of Agronomy, 2019)
articleThe main aim of this study was to find out how methyl esters with different fatty acid compositions affect the exhaust particle numbers. Along with fossil diesel fuel oil (DFO) and renewable diesel (HVO), a high-speed ... -
Exhaust Particle Numbers of High- and Medium-Speed Diesel Engines with Renewable and Recycled Fuels
(30.10.2020)
ArtikkeliväitöskirjaThe number of exhaust particles emitted from non-road diesel engines is regulated worldwide. This dissertation aimed to evaluate how different alternative fuels affect the exhaust particle number in high- and medium-speed ... -
Nonvolatile ultrafine particles observed to form trimodal size distributions in non-road diesel engine exhaust
(Taylor&Francis, 31.07.2020)
articleSome recent findings regarding the negative health effects of particulate matter increase the relevance of the detailed characteristics of particulate emissions from different sources and especially the nonvolatile fraction ... -
Performance and emissions of a medium-speed engine driven with sustainable options of liquid fuels
(SAE International, 15.09.2020)
articleEnergy production and transport are major global contributors of greenhouse gas emissions. Both sectors should reduce their use of fossil energy sources. Pollutant emissions must also be reduced without jeopardizing energy ... -
Performance and emissions of a non-road diesel engine driven with a blend of renewable naphtha and diesel fuel oil
(Technische Akademie Esslingen, 2019)
conferenceObjectDiesel engines are still the predominant power source in heavy-duty vehicle, non-road, marine and power generation applications globally. They are reliable stand-alone machines with a high brake thermal efficiency (BTE) ... -
Role of lubricating oil properties in exhaust particle emissions of an off-road diesel engine
(SAE International, 14.04.2020)
articleParticle number emissions from an off-road diesel engine without exhaust after-treatment were studied by using five different heavyduty lubricating oils in the engine. The study extends understanding on how the properties ... -
Selective Catalytic Reduction on Filter Performance Testing on Non-road Diesel Engine
(SAE International, 10.05.2021)
articleHigh-efficiency lean-burn compression ignition engines are expected to continue to play an important role as a power source for non-road mobile machinery. The challenge for these engines is that they suffer both high levels ... -
Voiteluaineiden ja polttonesteiden vaikutus työkonedieselmoottorin pakokaasun hiukkaskokojakaumaan
(2013)
DiplomityöPolttomoottorit, joita käytetään liikenteessä ja sen ulkopuolella, ovat yksi merkittävä hiukkaspäästöjen lähde. Pienhiukkaset syntyvät polttomoottorin sylinterissä, kun polttoaine-ilmaseos palaa epätäydellisesti. Ihmisille ...
