Abstract

Community economic activities that encourage motorized vehicles are getting higher. This exacerbates dependence on fossil fuels and air pollution. The outside air that is contaminated with exhaust gases from combustion products is very dangerous for human health. Motorized vehicles such as motorcycles are the largest cause of air pollution. Alcohols have high octane number and low viscosity. The use of ethanol and methanol alcohols is very diverse, so they are easy to obtain. Therefore, alcohol ethanol and methanol are suitable as premium fossil fuel mixtures. This study aims to observe the CO and HC emission characteristics of the gasoline engine using a premium-alcohol mixture of ethanol, methanol. The alcohol concentration was varied from 5% to 15% at 5% intervals. The petrol engine is operated at 2000, 3000, and 4000rpm. Commercial Gas Analyzers are used to measure CO and HC emissions coming out of the exhaust. The results of the observations present the CO and HC emissions of the engine with premium-ethanol fuel, methanol is lower than pure premium (P100). CO emissions from PE15 fuel decreased to 66,30%, and PM15 decreased to 90,63%. Meanwhile, PE15 fuel HC emissions decreased by 58,94%, and PM15 decreased by 68,60%.

Abstract

The suspension must provide comfort and safety to the vehicle. Therefore, it is necessary to analyze the load's effect on the pressure distribution on the axle so that the spring strength from the sideload force can be simulated. This study aims to analyze the sideload force of type C suspension springs using FEM. Spring variations are the number of different threaded coils, namely 11, 12, and 13. In the FEM simulation, the spring is given a load until 50mm, 100mm, 150mm, 200mm, and 250mm displacement occurs. The loading spreads to the X, Y, and Z axes. Each direction of the axis is measured by the pressure that occurs. The results showed that the pressure values that occur on the X, Y, and Z axes decreased with each increase in the number of screw coils. The lowest X-axis pressure reduction occurs in thread 12 at 63%. Meanwhile, the pressure on the Y axis decreased by 27% on the spring screw 12. The highest decrease in pressure on the Z axis occurred by 34% on the spring screw 12 compared to the spring screw 11.

Abstract

The increase in the volume of vehicles resulted in a crisis of fossil fuels so there is a need for alternative fuels to replace gasoline. Butanol and Diethyl Ether (DEE) are alternative fuels that can be added to gasoline. This is because the Octane Number and high O2 levels optimize combustion in the cylinder and increase torque and power and save fuel. This study compares the addition of butanol and DEE to gasoline on torque, power, and Brake Specific Fuel Consumption (BSFC). The study used a 160cc gasoline engine with a carburetor with engine speeds of 1000, 2000, and 3000 rpm. Variation of fuel mixture 5%, 10%, and 15% on gasoline. The results showed that the DEE15 mixture increased the highest torque by 28% at 3000 rpm compared to other fuel mixtures. Engine power also increases the highest by 28% when using a mixture of DEE15 compared to other fuels. Meanwhile, BSFC experienced the highest decrease of 19% when using the DEE15 mixture compared to other mixtures.

Abstract

Indonesia is one of the countries that uses the most motorized vehicles, which increases air pollution and fuel crises. Using biofuel is one solution to overcome this problem. Methanol is used as a mixture of Pertamax to produce environmentally friendly and renewable biofuel. This is because methanol has high octane and oxygen. Mixing methanol in Pertamax was carried out to analyze the impact of Torque, Power, and Exhaust Gas Temperature (EGT) of a 150cc petrol engine. Methanol 5%, 10%, and 15% was mixed into Pertamax with engine speed variations of 1000, 2000 and 3000 rpm. Dynotest is used to measure engine performance and thermocouples to measure EGT. Test results show the highest increase in engine torque and power of up to 25% at a speed of 2000 rpm with the PM15 mixture compared to P100. The highest reduction in EGT value occurred when using the PM15 mixture at a speed of 1000 rpm up to 28% compared to P100. This shows that the addition of methanol to Pertamax increases torque and power and reduces the EGT of the gasoline engine.

Abstract

The development of butanol as a gasoline additive is encouraged by the government to reduce pollution and the fuel crisis. This is because butanol is a green fuel that is environmentally friendly and can be produced. In addition, the octane number and high oxygen concentration in butanol optimize engine performance and improve exhaust emissions. This research correlates engine power and Brake specific fuel consumption (BSFC) with the BTE of gasoline-butanol-fueled engines and identifies the content of Nox compounds in exhaust gases through engine Exhaust Gas Temperature (EGT). The percentage of butanol in gasoline is 5% -15%. Engine speed from 1000-3000 rpm. Dynotest is used to measure BTE while the thermocouple is used to measure exhaust gas temperature. This research proves that the addition of butanol increases energy absorption which is converted into power with effective fuel consumption which means BTE increases. The highest BTE increase was 21.7% in the B15 blend. EGT decreased by 8.6% in the B16 mixture compared to B0. This identifies that the concentration of Nox in the exhaust gas also decreases.

Abstract

Blending fuels is an urgent alternative to reduce dependence on gasoline. Blending gasoline-alcohol bioethanol is realistic due to its high octane number properties and the abundant availability of raw materials. However, high viscosity results in inconsistent fuel mixing homogenization and decreased injector performance. The research aims to design a Dual Port Injection scheme as a dummy simulation of fuel blending so that bioethanol alcohol can be homogeneously blended with gasoline in the combustion chamber. The method used is observation of the Electric Fuel Injection working system and designing a Dual Port Injection Scheme. The research resulted in a Dual Port Injection scheme with the concept of doubling the injection-based fuel system and commands from the commercial Electric Control Unit to be forwarded to the bioethanol and bioethanol fuel pumps to supply fuel to the high pressure pipe.

Abstract

Dependence on fossil fuels requires a solution through alternative fuels. Ethanol is the recommended solution because it is easy to produce using raw materials that are abundant in nature, such as mangrove fruit. The Rhizophora Mucronata type of mangrove fruit contains 45.22% carbohydrates and is not used as raw material for human food. The research aims to produce ethanol biofuel from mangrove raw materials using multistage distillation. Experimental methods were applied at the stages of mangrove flour production, mangrove flour property testing, saccharification and fermentation, mangrove ethanol distillation, and analysis of potential performance and exhaust emissions. The research produced mangrove biofuel with an alcohol content of 28% which was produced from mangrove flour and had an ash content of 1.91%, protein, 2.24%, fat 0.53%, and water 11.61%. In addition, mangrove biofuel has higher viscosity and density properties than Gasoline at 0.8067Cp and 0.8115 g per mL respectively. The use of mangrove biofuel as a result of experiments is predicted to reduce fuel injection performance.

Abstract

The use of gasoline in vehicles produces CO, HC, and NOx emissions which are dangerous for the environment. Using butanol and ethanol as additional gasoline can reduce pollutant emissions. This is because alcohol has a high oxygen content and helps combustion more completely. This research compares the Exhaust Gas Temperature and Emissions results of EFI engines using gasoline-butanol and gasoline-ethanol. The EFI engine used has a capacity of 150CC. The alcohol used was butanol and ethanol with a percentage of 5%, 10%, and 15% in each test. The test results showed that the highest EGT reduction occurred in the E15 mixture at 23.98% and B15% at 8.65. Meanwhile, CO emissions experienced the highest reduction in E10 by 53.6% and B15 by 44.6%. HC emissions also experienced the highest reduction in E15 by 70.5% and B15 by 66.7% compared to gasoline. However, CO2 emissions increased to 17.07% in the E15 mixture and 11.46% in B15. This proves that the addition of ethanol produces more complete combustion than the addition of butanol.
