Abstract

To obtain maximum engine performance one way to do is to do modification the camshaft . Changes can be made to alter or modify the time to open and close the valve. As already unknow that big power generated by the engine is affected by the amount of residual gases that exit the combustion chamber. The amount of air and fuel mixture entering the combustion gases and regulated by the duration of the opening and closing of the valve.For it was necessary to study the extent to which the effect of the change by the duration of the camshaft to the increased power and torque of the engine, which can then be recovered size is definitely the most appropriate duration to generate great power and torque. Effective power produced at 220 ° camshaft duration variation is at 6000 RPM of 7.7 HP, variations in camshaft duration 227 °, ie at 8.49 HP at 6500 RPM, variations in camshaft duration 233 °, ie at 6500 RPM at 8.77 HP, variations in camshaft duration 239 °, ie at 9.53 HP at 6500 RPM. Average turning moment - resulting in maximum average variation of camshaft duration 220 °, ie at 6000 RPM of 1.37 Nm Variations camshaft duration 227 °, ie at 6000 RPM 1.43 Nm Variations camshaft duration 233 °, ie at 1.47 Nm at 6000 RPM Variations camshaft duration 239 °, ie at 6500 RPM of 1.51 Nm Keywords: effect of variations in the duration of the camshaft, power, torque, and fc (fuel concumtion).

Abstract

To reduce dependence on oil usage that increasing every day, many countries have adopted a substitution of petroleum fuels with renewable fuels such as ethanol is used as a blend in gasoline. Because ethanol can be produced from agricultural products such as corn, sugarcane, rice, etc., then the ethanol is one of the best alternative fuel in motor gasoline. Blending gasoline with ethanol would not fully produce a homogeneous mixture, need for additional treatment to obtain a more homogeneous results, one way is to heat the fuel. If the fuel is heated, there will be expansion or changes in fuel volume, in addition to the viscosity of the fuel will be decreased. It’s can be explained by the theory of thermodynamics, which states that the higher the temperature of a fluid, the fluid molecules will move quickly so at fixed volume will increase the pressure. Fuel with low viscosity will be atomized better, resulting smaller granules. With these conditions the process of mixing fuel with air will be more homogeneous so that the fuel burn more. The results obtained from testing the performance of the engine is the highest maximum torque obtained when using T40˚C fuel, with 6.37 Nm at 3400 rpm, increased 22.5%. The highest maximum power obtained when using T40˚C fuel with 3.450 HP at 5600 rpm, increased 5.11%. lowest Fuel Consumption average obtained at T40˚C fuel with 4.46% more efficient.

Abstract

The air pollution rate caused by the vehicles in big cities is now reach the critical limit. It affects the environmental health as well as the financial factors. To reduce the pollutant gas from the vehicle engines emission, a technology is needed. One of the technology is the application of catalytic converter  inside the exhaust emission. A research has been done on 125 cc motorcycle engine to modify its exhaust emission. The catalysts used in this research was made of copper and designed using the honeycomb system with various diameters ( 4, 6, 8, 10, 12 mm). The observation variables are catalyst temperature, CO and HC emission rate. The emission of CO and HC from the sample engine was then compared with the standard emission rates. Result showed that increase of the copper catalyst temperature resulted in decrease of  CO and HC emission rates. The decrease started to occur for all the catalysts at 225 oC. Optimum convertion efficiency is up to 47,93 % (CO) and 50,36 % (HC). Both optimum efficiency reached at the temperature of 325 oC using 8 mm diametered catalysts. Keywords : air pollutions, honeycomb system catalytic converter, temperature and copper

Abstract

Exhaust muffler system is commonly called is one vital part of a motor vehicle. This serves as an exhaust silencer is removed from the machine until at a certain noise level permitted with little possibility of a decline in torque and engine power. This study aims to determine the influence of the exhaust pipe diameter of straight throw gasoline engine performance, pressure, exhaust gas flow rate and intensity of noise generated. From the results of research in getting that throw straight exhaust pipe diameter which was able to improve gasoline engine performance, pressure, flow rate of exhaust gas and noise intensity. This is evident from the results of research that shows that there was an increase by using a exhaust pipe diameters greater straight throw. Keywords: exhaust pipe, exhaust silencer and straight throw

Abstract

Quality of product in various industries, especially in metal industry is the most attention so the product can compete and attract consumers. Surface roughness is one of the demand that must be fulfilled because it can be the initiation of cracks, especially when material receives recurring and fluctuating loading. Therefore, low surface roughness can produce a product with longer lifespan material. The goal of this study is to determine the most optimal combination of electroplating process with factors variety of voltage (volts), temperature (℃), and time of immersion (minutes) to produce a low values of surface roughness. This study uses an experimental design with Taguchi method. Contribution factors of control that produce the surface roughness values ​​were influenced significantly by control factor voltage (volts) amounted to 77.31% with an average roughness value of 1.29 μm. This is due to the increase in voltage which causes the deposition of electrolyte ions which is faster in the deposition structure of the specimen. Where as other control factors were not effected significantly on the temperature control factor amounted to 4.85% with an average roughness value of 1,32 μm. These results are possible because the temperature variations used (40℃ to 50℃) are still within the optimum operating temperature. And the other control factors is immersion time amounted to 10.13% with an average roughness value of 1,32. The result ware obtained because the length of coating time affected the quantity of deposition of nickel ions on the surface of the specimen. The result of optimal condition is the voltage level 2 (6 volts), the temperature at level 2 (45℃), and the immersion time at level 3 (25 minutes).

Technology of motor vehicles that are environmental friendly and fuel-efficient has been a demands in this era of energy crisis and global warming. The growth in number of motor vehicles which are very rapidly has raised the issue of air pollution that should be immediately resolved. Material utilization of iron (Fe) containing low carbon steel is often called low carbon as material for reducing pollution in this study applies principles of catalysation in motor vehicle exhaust gas pollutants with the material. The purpose of this research is generating a product of an architecture modification exhaust pollutants reducing motor vehicle by applying the technology of catalytic converter to reduce pollutant gases like CO and HC that are contained in the exhaust gas, as well as improving performance of the machine. The methods used to achieve these goals is the experimental method, which starts with design and creating of modification reducing exhaust gas as well as testing the effectiveness for emissions level and testing the poduct against the performance of the machine. The results of this research is the use of modification exhaust with application of catalytic converter technology with low carbon steel filler metals as catalysts in motor gasoline four steps can lower the levels of concentration of exhaust pollutants carbon monoxide (CO) and hydrocarbons (HC), increase torque, power, and lower fuel consumption than a standard exhaust conditions. Testing with a percentage of 75% volume of fibres low carbon steel has the best average results in the reduction of carbonmonoxide (CO) gases of 0.41% (lowered levels of CO 71.79% from the standard exhaust conditions) and hydrocarbons (HC) by 77.89 ppm (lowered levels of HC 61,25%), also can generate an increase in the average torque of 15.46% (with an average value of 4.23 Kg. m), an increase of the average effective power of 19.14% (with an average value of 11.76 HP), and decreasing in fuel consumption of 18.51% (with an average value of 1.48 Kg/hour) of the standard exhaust treatment conditions.
