The effect of hydrogen additives on the working process of a piston-type gasoline engine is studied. The indicator diagram has been built, and the operation of the piston engine on gasoline-air mixtures enriched with hydrogen in the amount of 0…20 % of the volume of air entering the engine has been analyzed. The possibility of obtaining satisfactory parameters when the engine works on gasoline with hydrogen additives is shown. The dynamics of the engine performance is studied depending on the oxidant excess coefficient. It has been established that the oxidizer excess ratio at which the maximum indicator pressure is reached is moved to the zone of poor mixtures. When the mixture is enriched with hydrogen in the amount of 20 % of the air volume, the maximum of indicator pressure pimax = 5.3...5.8 MPa is reached at α = 1.15...1.25, while for 10 % hydrogen addition the maximum pimax = 4.9...5.2 MPa takes place at α = 1.05...1.10 against pimax = 4.7...5.1 MPa at α = 0.90...0.95 for pure gasoline. According to the indicator diagram, the dynamics of intra-cylinder parameters is studied when the mixture is enriched with hydrogen. Thus, with a 20 % hydrogen addition the mean indicator pressure decreases by 12...19 %, despite a slight increase in the maximum cycle pressure (3...18 %), compared with gasoline operation, which leads to a proportional decrease in both the engine indicator power, and the indicator efficiency.

Performance And Emission

Vegetable oil as an alternative fuel for diesel engine has attracted much attention all over the world, and it is also expected to achieve the goal of global carbon neutrality in the future. Although the product after transesterification, biodiesel, can greatly reduce the viscosity compared with vegetable oil, the high production cost is one of the reasons for restricting its extensive development. In addition, based on the current research on biodiesel in diesel engines, it has been almost thoroughly investigated. Therefore, in this study, crude palm oil (CPO) was directly used as an alternative fuel to be blended with commercial diesel. The combustion, engine performance and emissions were investigated on a 4-cylinder, turbocharged, common rail direct injection (CRDI) diesel engine fueled with different diesel-CPO blends according to various engine loads. The results show that adding CPO to diesel reduces the maximum in-cylinder pressure and maximum heat release rate to 30 Nm and 60 Nm. The most noteworthy finding is that the blend fuels reduce the emissions of hydrocarbons (HC), nitrogen oxides (NOx) and smoke, simultaneously. On the whole, diesel fuel blended with 30% CPO by volume is the best mixing ratio based on engine performance and emission characteristics.

The requirement of hydrogen in the transport system is indispensable nowadays. Especially to fulfill the requirement from the transports and industry sector related with green technology implementation. As an alternative, a research has been conducted from a technical aspect on the profitability of using hydrogen onboard as fuel for internal combustion engine. Applications using a mixture of Gasoline with hydrogen (G+H2) can be used to increase the combustion performance especially on the reduction of hydrocarbon and carbon monoxide. In this study hydrogen as an alternative fuel in four-stroke motorcycles has been tested using a chassis dynamometer model ATV Inertial Dyno, 054-500-1K. Hydrogen requirement in the petrol mixing ratio is dependent on the operating system of the engine ignition system which is controlled by hydrogen pressure in the cylinder. Three stages of load test on the engine performance have been conducted on the chassis dynamometer, namely, load test L0 is equal 0 ampere (L0), load test L1 is equal 1 ampere, and load test L2 is equal 2. During the tests L0, L1 and L2, the average hydrocarbon gas readings decreased by 34 % and 58.2% (L0), 27.4% (L1) and 16.7% (L2) to 46ppm, 85ppm and 95ppm respectively versus gasoline engine 110ppm, 117ppm and 114ppm. And the overall average results of this study showed a reduction of carbon monoxide by 33 %. It proves the use of hydrogen (AL + HCl) in the stoichiometric ratio helps combustion when the oxygen content in the air and fuel mixture is not adequate especially for vehicles using gasoline as a fuel.

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.

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.
