“…Brake specific fuel consumption expresses the efficiency of the power produced on the crankshaft in response to the tested fuel consumed by an internal combustion engine. 13,[68][69][70] BSFC is an important performance indicator that expresses how much fuel should be consumed to reach the same engine load and is thus frequently used in the comparison of different test fuels. Since it is desired to reach the same load with less fuel consumption, it can be said that fuel with a lower BSFC value is more efficient in terms of engine performance.…”

The main objective of this study is to observe the effects of compression ratio (CR) variation on the engine performance and exhaust emission characteristics of a single-cylinder diesel engine fueled by waste fusel oil (F), waste cooking oil biodiesel (BD), and waste tire pyrolysis oil (P). For this purpose, Diesel RK software was used and the analyzes were performed at varying CRs of 18.3, 20.3, and 22.3. Analyzes were carried out at 2400 rpm constant engine speed, and varying engine loads (3, 6, 9, and 12 Nm). In the results, it is noticed that as the CR increased, BSFC (Brake Specific Fuel Consumption) value also increased for all test fuels. However, at low loads (3 and 6 Nm), the BSFC value decreased as the compression ratio increased after CR20.3. While the maximum BSFC value was obtained to be 560.55 g/kWh for P20 fuel at 3 Nm for CR20.3, the minimum one was achieved to be 46.76 g/kWh for neat diesel fuel at 12 Nm for 18.3. As the CR increased, the BTE (Brake thermal efficiency) value decreased for all test fuels at nearly all loads. However, at low loads (3 and 6 Nm), it is observed that the BTE improved as the CR increased after CR20.3. While maximum BTE was calculated to be 32.07% for P10F10 fuel at CR18.3 compression ratio at 12 Nm load, minimum one was achieved to be 15.36% for P20 at 3 Nm load for CR20.3. In addition, the NOx increased at all loads as CR increased for all test fuels. The maximum NOx value for P20 was recorded to be 1300 ppm at 12 Nm load and CR22.3. A minimum NOx was detected as 144. 56 ppm for P10F10 at 3 Nm, and CR18.3. In conclusion, the paper has proved that the experimental results are well-fitting with those of simulation software.

“…It helps to achieve improved oxidation during combustion that leads to lower CO emission. In addition, large surface-volume ratio of nanoparticles increases chemical reactivity resulting in complete combustion and less CO emissions [24]. Secondary atomization, assisted by the microburst of CeO2 in fuel blends, minimizes the formation of fuel-rich areas and leads to the reduction of CO emissions [13].…”

The production of greenhouse gases such as carbon dioxide causes global warming and many other environmental problems. Diesel engines are widely used due to their higher output torque value, better thermal efficiency and durability compared to gaso-line engines. Because of rapid consumption and mitigation of diesel as a fossil fuel, bio-diesel has recently received significant attention as a renewable energy source. There are several sources in order to produce biodiesel. Animal fats, inedible vegetable oils, waste oils and other low-value bioenergy raw materials are suitable sources for biodiesel pro-duction as they are renewable and have no impact on food safety. In this study, CeO2 nano additives at concentrations of 50 ppm and 75 ppm were added to cottonseed based biodiesel. The experiments were conducted at 4 different load conditions on a 3-cylinder water-cooled diesel engine. According to the test results, it was observed that with increasing nano additive concentration, thermal efficiency was increased and spe-cific fuel consumption was reduced. As well as, the results indicated that CO and soot emissions were reduced, while NOx emissions were increased due to the improvement of the combustion performance caused by CeO2 nanoparticles.

“…Bioethanol helps in increasing the oxygen content in the fuel blend which in turn reduces the air pollution, hydrocarbon HC, nitrogen oxides (NOX), and carbon monoxide (CO) emissions (Charlson et al, 2022;Abdullah andAriyanti, 2012, Dhahad et al, 2021). The firstgeneration of bioethanol produced from the sugar cane, corn, barley sugar, and cassava (Ekaab et al, 2019;Ağbulut and Sarıdemir, 2021). The researchers focused on produce the bioethanol from lignocellulosic materials which contribute in decrease the growing concern over food shortages, and environmental-friendly, which known as second-generation fuel of bioethanol.…”

Recently, most of the researchers focused on provide lower greenhouse gas emissions that emitted from diesel engines by using renewable fuels to be good alternative to the conventional diesel fuel. Ethanol can be derived from renewable sources such as sugar cane, corn, timber and dates. In the current study, the ethanol fuel used in the tests was derived from the dates. The effects of using exhaust gas recirculation (EGR) diesel-ethanol blend (E10) with on engine performance and emissions characteristics have been studied in diesel engine under various engine loads. This study focused the use of oxygen in the bio-ethanol composition to compensate for the decrease occurred by the addition of EGR, which improves the engine performance and reduces its emissions. In this experiment, the ratios of EGR were 10%, 20% and 30% as well as 10% ratio of ethanol was blended into the diesel fuel blend under fixed engine speed. A traditional (without additional systems to reduce emissions) four cylinders direct injection (DI) diesel engine was used for all tests. The brake specific fuel consumption (BSFC) increased with increasing the EGR ratio by 10%, 20% and 30% by 18.7%, 22.4% and 37.4%, respectively. The thermal efficiency decreased under variable conditions of engine load for different ethanol blends. Furthermore, the emissions of NOX decreased when fuelled B10 into the engine in comparison with diesel under low engine load. Significant reduction in the NOx emissions were found when applied EGR in the tests than to the absence EGR for E10 blend and diesel. The NOx reduction rate was 12.3%, 30.6% and 43.4% when EGR rate was 10%, 20% and 30%, respectively. In addition, the concentrations of HC and CO emissions decreased more by 8.23% and 6.4%, respectively, when using E10 in comparison with the diesel for various engine loads. It is indicated that the oxygen reduction by EGR effect was compensated from ethanol blend combustion. The results showed that the combination use of E10 and EGR leads to significant reduction in engine emissions accompanied with partial reduction in the engine performance.
