Feed stock cost and NOX emission are the major barriers for commercialization of biodiesel. Waste cooking oil is well identified as one of the cheapest feed stocks for biodiesel production. This chapter reduces NOX emission of waste cooking oil biodiesel. Test fuel blends are prepared by mixing diesel (20 to 50 v/v%), butanol (5 v/v%), and waste cooking oil biodiesel (45 to 75 v/v%). Fuel properties of waste cooking oil biodiesel are enhanced due to addition of diesel and butanol. Brake specific energy consumption of the blends is higher than diesel fuel. Harmful emissions like carbon monoxide, nitrous oxide, and smoke opacity are lower for blends than diesel fuel. Increasing biodiesel concentration in blend also reduces hydrocarbon emission to a significant extent. The obtained results justify the suitability of proposed cheap blends for diesel engine emission reduction.

Experimental tests have been carried out to evaluate the performance and emissions characteristics of a diesel engine when fuelled by blends of 25% vegetable oil with 75% diesel fuel, 50% vegetable oil with 50% diesel fuel, 75% vegetable oil with 25% diesel fuel, and 100% vegetable oil, compared with the performance, emissions characteristics of 100% diesel fuel. The series of tests were conducted and repeated six times using each of the test fuels. 100% of ordinary diesel fuel was also used for comparison purposes. The engine worked at a fixed speed of 1500 r/min, but at different loads respectively, i.e. 0%, 25%, 50%, 75% and 100% of the engine load. The performance and the emission characteristics of exhaust gases of the engine were compared and analyzed. The experimental results showed that the carbon monoxide (CO) emission from the vegetable oil and vegetable oil/diesel fuel blends were nearly all higher than that from pure diesel fuel at the engine 0% load to 75% load. Only at the 100% engine load point, the CO emission of vegetable oil and vegetable oil/diesel fuel blends was lower than that of diesel fuel. The hydrocarbon (HC) emission of vegetable oil and vegetable/diesel fuel blends were lower than that of diesel fuel, except that 50% of vegetable oil and 50% diesel fuel blend was a little higher than that of diesel fuel. The oxides of nitrogen (NOx) emission of vegetable oil and vegetable oil/diesel fuel blends, at the range of tests, were lower than that of diesel fuel.

Biodiesel is a standout amongst the most encouraging sustainable, elective and ecologically well disposed bio fuels that can be utilized in diesel engine without any modification. The exploratory work has been led on a four-chamber, four - stroke, direct infusion (DI) diesel motor. In this examination, biodiesel (Produced from cotton seed oil by transesterification procedure) and typical diesel have been utilized as a reference fuel. In this examination, two diverse nanoparticle fuel added substances in particular MgO2 and CeO2 were added to biodiesel at the option measurement of 250 and 500ppm. An experimental analysis of performance and emission for present of metal oxide nano-particles with cotton seed biodiesel used as a fuel in CI diesel engine and also optimized the quantity of dosing metal oxide can be effective for better performance. In this investigation could be done with present and absent of metal oxide additives are likewise displayed. The present of MgO2 nano-particles has been increased the flash point and viscosity of the biodiesel. It was clearly noticed that the Expansion of MgO2 nanoparicles resulted lower HC and NOx outflows.

Abstract This research investigates the effects of the addition of Fe2O3 and Al2O3 nanoparticles (30, 60, and 90 ppm) and Fe2O3-Al2O3 hybrid nanoparticles to pure diesel fuel on the combustion, performance and emission characteristics of a diesel engine. The results indicated that fuel blends improved the combustion (in-cylinder pressure and heat release rate), performance (power, fuel consumption, and thermal and exergy efficiency), and emission characteristics of the engine. The results showed that the peak combustion pressure increased by 4% and the heat release rate was improved by 15% in comparison with pure diesel with the addition of the nanoparticles. Moreover, the rate of pressure rise increased by 18% compared to pure diesel with nanoparticle additives. Based on the results, the effects of Fe2O3 fuel blends on brake power, BTE, and CO emission were more than Al2O3 fuel blends, such that it increased power and thermal efficiency by 7.40 and 14%, respectively, and reduced CO emissions by 21.2%; moreover, the blends with Al2O3 nanoparticle additives in comparison with Fe2O3 nanoparticle blends showed a better performance in reducing BSFC (9%), NOx (23.9%), and SO2 (23.4%) emissions. Overall, the Fe2O3-Al2O3 hybrid fuel blend is the best alternative if the performance and emission characteristics of the engine are both considered.

Substitution ratio is an important parameter influencing on the performance of dual-fuel engine. In order to study the effects of substitution ratio on the emission characteristics of diesel/ methanol dual-fuel engine, a 6-cylinder turbocharged diesel engine was converted into a dual-fuel engine fueled with pilot diesel fuel and methanol. Methanol was injected into the intake pipe and ignited by pilot diesel fuel. Experiments were performed at a constant speed of 1400 r/min, and at three different engine loads of 40%, 60% and 100%. The experimental results indicate that CO and HC emissions of dual-fuel mode both increase significantly with the increase of substitution ratio, and are higher than those of diesel mode. Compared to diesel mode, dual-fuel mode generates lower NOx and smoke emissions. In addition, as substitution ratio increases, NOx and smoke emissions are decreased.

The main purposes of this research were to study the diesel engines' performance and emission characteristics of quaternary fuels, as well as to analyze their tribological properties. The quaternary comprised waste plastic pyrolysis oil, waste cooking oil biodiesel, palm oil biodiesel, and commercial diesel. Their compositions were analyzed by gas chromatography and mass spectrometry. By using mechanical stirring, four quaternary fuels with different compositions were prepared. Because Malaysia is expected to implement B30 (30% palm oil biodiesel content in diesel) in 2025, B30a (30% palm oil biodiesel and 70% commercial diesel) mixture was prepared as a reference fuel. In total, 5%, 10%, and 15% of each waste plastic pyrolysis oil and waste cooking oil biodiesel were mixed with palm oil biodiesel –commercial diesel mixture to improve fuel characteristics, engine performance, and emission parameters. The palm oil biodiesel of the quaternary fuel mixture was kept constant at 10%. The results were compared with B30a fuel and B10 (10% for palm oil biodiesel and 90% for diesel; commercial diesel). The findings indicated that compared with B30a fuel, the brake power and brake thermal efficiency of all quaternary fuel mixtures were increased by up to 2.78% and 9.81%, respectively. Compared with B30a, all quaternary fuels also showed up to a 6.31% reduction in brake-specific fuel consumption. Compared with B30a, the maximum carbon monoxide and carbon dioxide emissions of B40 (60% commercial diesel, 10% palm oil biodiesel, 15% waste plastic pyrolysis oil and 15% waste cooking oil biodiesel) quaternary fuel were reduced by 19.66% and 4.16%, respectively. The B20 (80% commercial diesel, 10% palm oil biodiesel, 5% waste plastic pyrolysis oil and 5% waste cooking oil biodiesel) quaternary blend showed a maximum reduction of 41.86% in hydrocarbon emissions collated to B30a. Compared with B10, the average coefficient of friction of the quaternary fuel mixture of B40, B30b (70% commercial diesel, 10% palm oil biodiesel, 10% waste plastic pyrolysis oil and 10% waste cooking oil biodiesel), and B20 were reduced by 3.01%, 1.20%, and 0.23%, respectively. Therefore, the quaternary blends show excellent utilization potential in diesel engine performance.
