Abstract

Pressurized fuel is fuel that is pumped by a fuel pump (fuel pump) from the fuel tank to the injector. Fuel pressure that is too low will greatly affect the performance of the engine and the risk of engine failure. Fuel pressure measurement aims to determine the performance of the fuel pump (fuel pump) is still able to work well or not. The method used is a qualitative method. The construction design starts from the planning process which includes making the concept of design, observation and processing of data so that it is found that the design is capable of reading fuel pressure from the fuel pump and is easy to use. To strengthen the results of the study, it is complemented by a literature review that has close relevance to the subject matter. Based on the results of testing that has been achieved from the entire process of making and testing the design of fuel pump pressure tester on injection motors, it can be concluded that the functional test in the last process shows that the tool can work well and is able to provide information on fuel pressure measurements from the fuel pump.

Abstract

This study aims to determine the effect of modification of the Honda Tiger 2000 on exhaust emissions of CO and HC. The method used is to modify the carburettor venturi piston and replace the rocker arm with a roller rocker arm. The exhaust emission test used a gas analyzer type SUKYOUNG SY-GA 401. The object of the study was a Honda Tiger 2000 motorcycle. The results showed that modification of the Honda Tiger 2000 motorcycle at idle, 1000 rpm, 1500 rpm, and 2000 rpm increased CO emissions but reduced HC emissions. Based on comparing the motorcycle emission threshold values for manufacture ≤ 2010, namely CO emissions exceeding 5.5% and HC emissions less than 2400 ppm. Pertamax Turbo fuel consumption is more efficient than Pertalite with a distance ratio of 45 km requiring 1L Pertamax Turbo and 1.4L Petalite.

Abstract

The purpose of this research is to get a clear picture of the process of reconditioning and testing the 1984 Toyota Rino diesel engine. And to find out which components must be renovated for excellent engine performance. This research was conducted at the Piksi Ganesha Polytechnic Laboratory of Indonesia. The research method used is qualitative. The result of the reconditioning process is that several diesel engine components must be replaced in gaskets, air, and fuel filters. The results of testing the diesel engine Toyota Rino 1984 are: 1) Injector test, all injectors’ functions should run when tested using a pressure nozzle test; namely, the manometer shows 3000 psi when the lever is pressed, the nozzle can spray fuel tightly, and the nozzle does not leak; 2) Compression test, all cylinders are still in good condition when tested using a cylinder pressure tester, namely the manometer shows the number 30 kg/cm2.

Abstract

The research aims to determine the effect of different spark plug variations on fuel consumption. The method used is a descriptive method. The tools and materials used are: copper spark plugs, platinum spark plugs, iridium spark plugs, 5 liter measuring cup, and pertalite. Fuel consumption analysis compared copper, platinum and iridium spark plugs with rpm 700, 1000, 1500, and 2000. Test results: 1) Fuel consumption for copper spark plugs with rpm 700, 1000, 1500, and 2000, namely 40ml, 10ml, 15ml and 10ml. 2) Fuel consumption for platinum spark plugs with rpm 700, 1000, 1500 and 2000, namely 20ml, 5ml, 25ml and 20ml. 3) Fuel consumption for iridium spark plugs with rpm 700, 1000, 1500 and 2000 is 50ml, 10ml, 10ml and 10ml. So platinum spark plugs are more fuel efficient than copper and iridium spark plugs.

Abstract

This study aims to test the results of converting a gasoline-fueled motorcycle with an injection system into an electric motorcycle in terms of horsepower and torque. The data from the unit conversion testing in this study used an experimental method with data analysis that compares the results of dyno tests on a gasoline-fueled motorcycle unit using variations of fuel octane values, with dyno test data from the unit after being converted into an electric vehicle. The testing equipment and materials used in the study were: Sportdyno 4.0, a 110 CC Injection Matic Motorcycle unit, and Pertamax Fuel. The results of this study show that the highest power and torque on the gasoline-powered motorcycle were 6.2 Horsepower (HP) at 6500 to 6600 rpm, and the highest torque was 6.8 N.m at 6400 rpm for the unit before conversion. After the conversion, the highest power achieved was 5.4 HP at an average of 2250 to 2500 rpm, and the highest torque was 28.48 N.m at 1100 rpm for the converted vehicle unit.Thus, it can be concluded from the average data analysis of the power and torque tests that the result of the electric vehicle conversion is 5.4 HP and 28.48 N.m.

Abstract

The ability of diesel injectors to spray fuel greatly affects the homogeneity of the mixture and its penetration power in the combustion chamber. The research method used is an experiment with data presented descriptively. The objectives of this study are to determine the effect of nozzle opening pressure on fuel consumption, to identify the nozzle opening pressure at which fuel consumption is lowest, and to determine the effect of cetane number on fuel consumption in diesel engines. The results of this study indicate that the nozzle opening pressure of the injector in a diesel engine significantly affects fuel consumption, regardless of whether the engine is operating at low, medium, or high RPM. The lowest fuel consumption in a diesel engine occurs at a nozzle opening pressure of 10 MPa. The cetane number of the fuel does not significantly affect fuel consumption in a diesel engine, specifically a single-cylinder indirect injection diesel engine. Keywords: Injector Pressure, Fuel Consumption, Diesel.
