It has been proven that vehicle emissions such as oxides of nitrogen (NOx) are negatively affecting the health of human beings as well as the environment. In addition, it was recently highlighted that air pollution may result in people being more vulnerable to the deadly COVID-19 virus. The use of biofuels such as E5 and E10 as alternatives of gasoline fuel have been recommended by different researchers. In this paper, the impacts of port injection of water to a spark ignition engine fueled by gasoline, E5 and E10 on its performance and NOx production have been investigated. The experimental work was undertaken using a KIA Cerato engine and the results were used to validate an AVL BOOST model. To develop the numerical analysis, design of experiment (DOE) method was employed. The results showed that by increasing the ethanol fraction in gasoline/ethanol blend, the brake specific fuel consumption (BSFC) improved between 2.3% and 4.5%. However, the level of NOx increased between 22% to 48%. With port injection of water up to 8%, there was up to 1% increase in engine power whereas NOx and BSFC were reduced by 8% and 1%, respectively. The impacts of simultaneous changing of the start of combustion (SOC) and water injection rate on engine power and NOx production was also investigated. It was found that the NOx concentration is very sensitive to SOC variation.

This research investigated the effects of ethanol blending with methanol-gasoline as fuels in spark ignition engine and how it affects engine performance and emissions. Four ethanol-methanol-gasoline (GEM) blends were prepared with variable ethanol concentrations (0%, 5%, 10%, 15%) and constant methanol concentration (10%) and denoted as M10, E5M10, E10M10, and E15M10 in reference to each respective alcohol constituents. Physicochemical properties testing revealed that density and kinematic viscosity of GEM fuel blends increases with ethanol concentration. E15M10 has shown the most increase in density and kinematic viscosity with 10.7% and 18.7% increase respectively. In contrast, calorific value decreased as ethanol concentration decreases. E15M10 displayed the lowest calorific value at 16.9% lower than gasoline. Meanwhile, engine performance and emissions test showed that GEM fuels generally possess increased average Brake Thermal Efficiency (BTE) than pure gasoline. However, average Brake Specific Fuel Consumption (BSFC) for pure gasoline is lower. E15M10 displayed highest increment of BSFC at 17.2% average increase. Meanwhile, E10M10 displayed the highest improvement in BTE with an average of 9.4% increase. Exhaust emissions indicate that all GEM blends produced increased carbon dioxide (CO2) and oxides of nitrogen (NOx) emissions while carbon monoxide (CO) emissions decreases. E15M10 showed the most reduction in CO emissions with 90.6% decrease while E10M10 has shown the most increased CO2 and NOx emissions with 110% and 6.7 times increase respectively. In conclusion, up to 15% volume of ethanol blending with 10% volume methanol-gasoline was able to improve engine performance and emissions in terms of BTE and CO emissions.
