The increasing volume of motorized vehicles leads to an increase in dependence on fossil fuels and an increase in air pollution. The problem can be reduced by utilizing renewable alcohol fuels such as methanol, ethanol, and butanol. The high number of octane and oxygen content is the main reason. Therefore, this study aims to observe the exhaust emissions of the 160 cc gasoline engine with a mixture of methanol, ethanol, and butanol. The percentage of alcohol used is 0 % to 30 % by volume. The test was carried out in 2000, 3000, and 4000 rpm. The results of the study explained that the use of methanol, ethanol, butanol in the fuel mixture was proven to reduce exhaust emissions. CO and HC emissions decreased as the percentage of alcohol in the fuel increased. The highest reduction in CO and HC emission in methanol blended fuel was 30 %, 94.55 % and 82.71 %, respectively. Meanwhile, CO2 emissions increased by 34.88 % at 2000 rpm engine speed. Based on this test, the addition of methanol to fuel can reduce exhaust emissions better than ethanol and butanol.

Automotive sector is one of the major contributors to air pollution and global warming due to the carbon residue and smoke opacity emission. Today, the trend of decreasing sources of petroleum fuel has led to innovation of other resources such as alternative fuel. Alternative fuel can be produced from biomass such as alcohol in which it is produced by fermentation of sugar, cane and corn. This experiment was conducted to investigate the effects of ethanol on gasoline engine performance and exhaust emissions. A four-stroke, single cylinder engine was tested by different range of ethanol volume percentages i.e. 10% (E10), 20% (E20) and 30% (E30) blended with fossil gasoline. The experiment was carried out at variations of engine speed and constant load. The engine speeds used for a constant load at 2 Nm were 2000rpm, 2500rpm and 3000rpm. From the results obtained, it shows that the brake specific fuel consumption for the blended fuel is better than gasoline fuel. Combustion efficiency of gasoline engine has improved with the use of ethanol-gasoline blends. Exhaust emissions such as CO and smoke opacity are decreased due to the presence of oxygenated properties of ethanol in blended fuel. However, emissions of CO2 are increased due to the high combustion temperature. In overall, the E20 shows the best results for all measured parameters at all engine test conditions.

Blended Fuels

Air pollution, especially in large cities around the world, is associated with serious problems both with people’s health and the environment. Over the past few years, there has been a particularly intensive demand for alternatives to fossil fuels, because when they are burned, substances that pollute the environment are released. In addition to the smoke from fuels burned for heating and harmful emissions that industrial installations release, the exhaust emissions of vehicles create a large share of the fossil fuel pollution. Alternative fuels, known as non-conventional and advanced fuels, are derived from resources other than fossil fuels. Because alcoholic fuels have several physical and propellant properties similar to those of gasoline, they can be considered as one of the alternative fuels. Alcoholic fuels or alcohol-blended fuels may be used in gasoline engines to reduce exhaust emissions. This study aimed to develop a gasoline engine model to predict the influence of different types of alcohol-blended fuels on performance and emissions. For the purpose of this study, the AVL Boost software was used to analyse characteristics of the gasoline engine when operating with different mixtures of ethanol, methanol, butanol, and gasoline (by volume). Results obtained from different fuel blends showed that when alcohol blends were used, brake power decreased and the brake specific fuel consumption increased compared to when using gasoline, and CO and HC concentrations decreased as the fuel blends percentage increased.

For spark ignition engines, the fuel-air mixture preparation process is known to have a significant influence on engine performance and exhaust emissions. In this paper, an experimental study is made to characterize the spray characteristics of an injector with multi-disc nozzle used in the engine. The distributions of the droplet size and velocity and volume flux were characterized by a PDA system. Also a model of a 4 cylinder multi-point fuel injection engine was prepared using a fluid dynamics code. By this code one-dimensional, unsteady, multiphase flow in the intake port has been modeled to study the mixture formation process in the intake port. Also, one-dimensional air flow and wall fuel film flow and a two-dimensional fuel droplet flow have been modeled, including the effects of in-cylinder mixture back flows into the port. The accuracy of model was verified using experimental results of the engine testing showing good agreement between the model and the real engine. As a result, predictions are obtained that provide a detailed picture of the air-fuel mixture properties along the intake port. A comparison was made on engine performance and exhaust emission in different fuel injection timing for 2600 rpm and different loads. According to the present investigation, optimum injection timing for different engine operating conditions was found.

The depletion of fossil fuels, rising of earth temperatures and declining of air quality are an unavoidable phenomenon today. Bioethanol fuel is one solution to reduce this problem that comes from renewable raw materials. The purpose of this study is to investigate engine performance and exhaust emissions at gasoline engine by using the sorghum seeds bioethanol-pertalite blends with different mixed ratios (10%, 15%, and 20%). The test is performed on a four-stroke gasoline engine without modification. Engine speeds vary from 1000 to 4000 rpm, and properties of the sorghum seeds bioethanol-pertalite blends are measured and analyzed. In addition, engine torque, brake power, brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) as well as carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) emissions are measured. The results show that BSFC decreased while BTE increased for a fuel blends containing 20% bioethanol at 3500 rpm engine speed, with each maximum value of 246.93 g/kWh and 36.28%. It is also found that CO and HC emissions are lower for the sorghum seeds bioethanol-pertalite blends. Based on the research results, it can be concluded that the sorghum seeds bioethanol-pertalite blends can improve engine performance and reduce exhaust gas emissions.

One of the causes of air pollution today is the increasing use of motorized vehicles. The use of technology has also been pinned on many wrong vehicles to improve the quality of the exhaust emissions that have been produced. One of them is EFI (Electronic Fuel Injection) technology which has been embedded in many vehicles. The component that has an effect on improving the quality of exhaust emissions at EFI is an electronic fuel pump. The fuel pressure on the electronic pump can be adjusted manually. This study aims to determine changes in fuel pressure on exhaust gas emission levels. This research uses an experimental method, where the fuel pressure is varied from the pressure of 50psi, 40psi, 30psi and 20psi, and the engine speed is varied from 800rpm, 1500rpm, 2250rpm, 3000rpm and 3750rpm. The results of the data obtained are analyzed using the quantitative description method. The test results showed that there was a decrease in the lowest CO level of 0.663% at 30psi fuel pressure with 3750rpm engine speed. HC also experienced a decrease, the lowest decrease was obtained in the value of 280ppm at 20psi fuel pressure and 3750rpm engine speed. While CO2 has increased, the highest increase of 13.33% was achieved at 20psi fuel pressure and 3750rpm engine speed.

Abstract The consumption of fossil fuels raises major issues, such as energy availability and environmental preservation. In order to minimize these issues, it is important to propose alternative fuel. Alternative fuel to be proposed should be easy to apply current type of enginethat do not require engine modification and environmentally friendly. This study aims to determine the effect of addition of methanol as a non-fossil fuel mixture into RON 88 gasoline. The ratio of mixture is 80% of RON 88 gasoline and 20% of methanol. We conducted the experiment to determine the mixture effect on fuel properties, engine performance, engine vibration, engine noise, and exhaust emissions. The engine simulation utilized the TV-1 engine (Kirloskar Oil Engines Ltd.). The results show that the engine performance of fuel mixed with methanol tends to be better even though the fuel consumption is higher, the highest specific fuel consumption in the methanol mixture is 2.9 kg/kwh while the specific fuel consumption for gasoline without a methanol mixture is 2.64 kg/kwh. The largest engine vibration occurred in the measurement of the vertical radial direction of 36 m/s2 and 34 m/s2 for with methanol and without the addition of methanol, at 1200 rpm to 1600 rpm respectively. Engine noise is higher for fuel mixed with methanol with the largest value of 86.4 dB compared to 85.7 dB for pure gasoline. Lower emission levels for fuel blended with methanol, where the highest HC emission for pure gasoline is 32 ppm while fuel mixed with methanol is 17 ppm.

Study Results

Fuel quality is an important indicator for the suitability of alternative fuel for the utilization in internal combustion (IC) engines. In this paper, light naphtha and fusel oil have been introduced as fuel additives for local low octane gasoline to operate a spark ignition (SI) engine. Investigated fuel samples have been prepared based on volume and denoted as GN10 (90% local gasoline and 10% naphtha), GF10 (90% local gasoline and 10% fusel oil), and GN5F5 (90% local gasoline, 5% naphtha and 5% fusel oil) in addition to G100 (Pure local gasoline). Engine tests have been conducted to evaluate engine performance and exhaust emissions at increasing speed and constant wide throttle opening (WTO). The study results reveal varying engine performance obtained with GN10 and GF10 with increasing engine speed compared to local gasoline fuel (G). Moreover, GN5F5 shows higher brake power, lower brake specific fuel consumption, and higher brake thermal efficiency compared to other investigated fuel samples over the whole engine speed. The higher CO and CO2 emissions were obtained with GN10 and GF10, respectively, over the entire engine speed and the minimum CO emissions observed with GN5F5. Moreover, the higher NOx emission was observed with pure local gasoline while the lowest was observed with GF10. On the other hand, GN5F5 shows slightly higher NOx emissions than GF10, which is lower than GN10 and gasoline. Accordingly, GN5F5 shows better engine performance and exhaust emissions, which can enhance the local low gasoline fuel quality using the locally available fuel additives.

The results of gasoline engine emissions purchased by the Toyota ANZ1 are statistically evaluated with the catalyst developed (La2O3/Zn/Na). The tests were carried out in the combustion test bench developed. The results show that the percentage of CO emissions increases as the engine speed increases, reaching values higher than 4%, with the original catalyst being that with the catalyst developed, which contains 5% by weight of Lanthane emissions of CO are close to 2%, but when the engine doesn´t have the oxygen sensor. When the concentration of Lanthane is 7,5%, the efficiency reaches 7% of CO removal and 32% of HC removal. The statistical test T for independent samples indicates that the original catalyst and that developed presently a statistically significant difference in catalytic efficiency. On the contrary, when the oxygen sensor is connected, the catalyst developed is also efficient. On the other hand the emissions of HC decrease as the engine speed increases reaching values close to 200ppm which corresponds to the EURO III standard, being that with the catalyst developed, which contains 7,5% by weight of LNG, the HC emissions It is 147ppm showing good performance.
