“…The complete results for 95 octane fuels, an average CO emission of 0.27% deduced for E15, compared to 0.25% shown by E10, an increase of 9.4%. For its part, E20 showed an average CO concentration of 0.25%, which leads to a null variation of data obtained for both fuels (E15 and E10) [29,30]. .…”

The present work carries out an experimental comparative analysis of the performance and emission of exhaust gases of the Otto cycle with four automotive times. The comparison was made between alternative fuels such as E10, E15, and E20, with both 90 and 95 octane each the commercialized fuel. The experimental tests were carried out with an engine load corresponding to 25% of the maximum load. After carrying out the tests, the following conclusions can be reached: on the performance and effective parameters of the engine, the obtained best indicator, and as expected, was the case E10 (90 octane). Also, the E15 (90 octane) showed a slight difference compared to the reference fuel E10 (90 octane). About emissions, it was found that these decrease as the concentration of ethanol in the fuel increases.

“…For the 95 octane fuels, an average NO emission corresponding to the E15 of 224.2 ppm can be seen, compared to 151.72 ppm of E10, representing an increase of 49%. Likewise, in the case of E20, it presents a value of 256.6 ppm, representing an increase of 70.6% to E10[29].…”

“…The O 2 found present in the exhaust gases using biodiesel is higher than that recorded when using diesel. In biodiesel, a certain amount of oxygen is present, higher than that found in diesel, and participates in the combustion reaction [26]. Part of the oxygen enters with the intake air and leaves without reacting with the exhaust gases.…”

The exploitation of fossil fuels has fueled the modern world’s development since the industrial revolution. Other energy sources, such as wood, charcoal, and animal power, were displaced by these fuels, which were relatively easy to obtain, had low cost of production, and were easily transportable. The possibility of these fossil reserves being depleted in the medium term, combined with an increase in environmental awareness and the reality of environmental degradation, has changed the situation, reactivating the search for alternative fuels. Biofuels such as bioethanol, biomethanol, and biodiesel are among the alternative fuels gaining popularity due to their environmental benefits. This research investigates the behaviour of a diesel engine that runs on biodiesel (a fuel made from new and unrefined algae oil), ethanol (an essential raw nanomaterial that is readily available in India), and nanometal additives.

“…They all show good ignition quality (indicated by a high cetane number), which is higher than diesel fuel and minimum standard limits, and good low temperature flow properties. The energy content is generally lower than conventional diesel, but Chlorella protothecoides, Stoechospermum marginatum, Neochloris oleoabundans, and Crypthecodinium cohnii algae biodiesel calorific values are close to fossil diesel (Table 9) [125].…”

Key Targets for Improving Algal Biofuel Production

A number of technological challenges need to be overcome if algae are to be utilized for commercial fuel production. Current economic assessment is largely based on laboratory scale up or commercial systems geared to the production of high value products, since no industrial scale plant exits that are dedicated to algal biofuel. For macroalgae (‘seaweeds’), the most promising processes are anaerobic digestion for biomethane production and fermentation for bioethanol, the latter with levels exceeding those from sugar cane. Currently, both processes could be enhanced by increasing the rate of degradation of the complex polysaccharide cell walls to generate fermentable sugars using specifically tailored hydrolytic enzymes. For microalgal biofuel production, open raceway ponds are more cost-effective than photobioreactors, with CO2 and harvesting/dewatering costs estimated to be ~50% and up to 15% of total costs, respectively. These costs need to be reduced by an order of magnitude if algal biodiesel is to compete with petroleum. Improved economics could be achieved by using a low-cost water supply supplemented with high glucose and nutrients from food grade industrial wastewater and using more efficient flocculation methods and CO2 from power plants. Solar radiation of not <3000 h·yr−1 favours production sites 30° north or south of the equator and should use marginal land with flat topography near oceans. Possible geographical sites are discussed. In terms of biomass conversion, advances in wet technologies such as hydrothermal liquefaction, anaerobic digestion, and transesterification for algal biodiesel are presented and how these can be integrated into a biorefinery are discussed.
