“…It is found that fuel consumption is reduced by about 3.63% for diesel doped with cerium oxide nanoparticles of molar concentration 10 ppm. This proves that cerium oxide nanoparticles are having high oxygen boosting capacity that allows for complete combustion of the fuel, giving rise to less usage of fuel [13].…”

“…This is because of the fact that the cetane number of diesel doped with nanoparticles is higher than that of neat diesel. The effects of a shorter delay period combined with oxygen boosting catalytic nanoparticles result in better combustion simultaneously reducing the HC emissions [13]. Hydrocarbon emission for diesel doped with cerium oxide nanoparticles of molar concentration 10 ppm is decreased by 6.3% at the maximum peak load.…”

Diesel fuel is necessary for farming, transport, and industrialized sector. It contributes to the wealth of the universal economy while it is widely used due to having higher flexibility, combustion efficiency, consistency and handling facilities. However, emissions from fossil fuel are considered as the main source of environmental pollution. Thus, it becomes necessary to reduce emission by improving the performance of the engines. Recently the addition of catalytic material like nanoparticles to diesel proves to be a hopeful solution to reduce emission without much modification of the existing engine design. In the present study, the influence of nanoparticles doped with diesel on the performance and emission characteristics are carried out in a naturally aspirated, single-cylinder, four-stroke, water-cooled, 3.7 kW, direct-injection compression-ignition engine is coupled with eddy current dynamometer and high-speed data acquisition system. Cerium Oxide nanoparticles are selected as the best oxygen boosting catalytic nanoparticle and it is prepared by the sol-gel process. Nanoparticles, then doped with diesel with the help of an Ultrasonicator with different molar concentrations (5 ppm, 7.5 ppm, 10 ppm, 15 ppm). Fuel properties of nano doped fuel samples are tested and presented in this paper. The DI CI engine experimental results were found to be brake thermal efficiency is increased by 3.6% by simultaneously reducing fuel consumption by 3.63% and also harmful environmental pollution like carbon monoxide, unburned hydrocarbon, carbon dioxide, and smoke level are decreased by 9.11%, 6.3%, 3.12%, and 12.6% respectively compared to pure diesel. It may be due to the enhanced surface to volume ratio, catalytic activity and improving the mixing rate of fuel and air in the combustion chamber.

“…Improvement in the performance of diesel engines is an important challenge to be addressed, in the current era due to the fast depletion of fossil fuel resources as well as due to the harmful hydrocarbon and nitrogen oxide emissions. Efforts are also made for the reformulation of diesel fuel to reduce these harmful emissions without affecting the physicochemical properties of fuel such as viscosity, flash and fire point, and so forth [1][2][3].…”

Cerium oxide being a rare earth metal with dual valance state existence has exceptional catalytic activity due to its oxygen buffering capability, especially in the nanosized form. Hence when used as an additive in the diesel fuel it leads to simultaneous reduction and oxidation of nitrogen dioxide and hydrocarbon emissions, respectively, from diesel engine. The present work investigates the effect of cerium oxide nanoparticles on performance and emissions of diesel engine. Cerium oxide nanoparticles were synthesized by chemical method and techniques such as TEM, EDS, and XRD have been used for the characterization. Cerium oxide was mixed in diesel by means of standard ultrasonic shaker to obtain stable suspension, in a two-step process. The influence of nanoparticles on various physicochemical properties of diesel fuel has also been investigated through extensive experimentation by means of ASTM standard testing methods. Load test was done in the diesel engine to investigate the effect of nanoparticles on the efficiency and the emissions from the engine. Comparisons of fuel properties with and without additives are also presented.

Τα αποτελέσματα ήταν αποθαρρυντικά επειδή αφ'ενός μεν η ταπείνωση του κατωφλιού αναγέννησης ήταν ανεπαρκής (max 80-100°C), αφετέρου εξαιτίας της κατάλυσης των αντιδράσεων παραγωγής θειικών από το θείο που περιέχεται στο καύσιμο του Diesel [22,41,65,76].…”

“…Από το 1982 ήταν ήδη γνωστό ότι, όταν μειωθεί σημαντικά το θερμοκρασιακό κατώφλι αναγέννησης με τη χρήση καταλυτικών προσθέτων, τα σωματίδια που συλλέγονται στα χαμηλά φορτία ή στο ρελαντί αυταναφλέγονται σε αισθητά χαμηλώτερες θερμοκρασίες από αυτά που συλλέγονται στο πλήρες φορτίο και τα οποία αποτελούνται κυρίως από "μαύρο καπνό" [11,17]. Αντίθετα στην περίπτωση της καθαρά θερμικής αναγέννησης οι απαιτούμενες θερμοκρασίες εισόδου του καυσαερίου είναι τόσο υψηλές, που το περιεχόμενο των σωματιδίων σε υδρογονάνθρακες έχει εξαερωθεί κατά το μεγαλύτερο μέρος του προτού προλάβει να αναφλέγει και να προσδώσει ενέργεια για την ανάφλεξη του "μαύρου καπνού" [41]. Ο Wiedemann και οι συνεργάτες του [83] επιχείρησαν να μειώσουν τις θερμοκρασίες αυτανάφλεξης, σε μόνιμο σημείο λειτουργίας, εμπλουτίζοντας το καυσαέριο πριν την παγίδα με αέριους υδρογονάνθρακες (προπάνιο) ή και με σταγονίδια καυσίμου diesel χωρίς όμως αποτέλεσμα.…”
