Abstract

The rapid development of information technology makes a lot of electronic components used invarious fields. The component that is often used is a microcontroller. The microcontroller is used as theregulator and the automation system. This study aims to design a microcontroller-based water injection (WAI)system on the motorcycle.The experiment was conducted with an experimental method. Object of the research is honda megapro 2009 motorcycle. The design of microcontroller-based WaI done through the following steps: (1) designinga microcontroller-based WaI system using the proximity sensor signals, (2) designing the voltage regulatorcircuit, (3) designing AT89S51 microcontroller circuit, (4) designing injector circuit, (5) designing a series of7-segment display, and (6) making programming the microcontrol ler on the WaI that is used to inject water or amixture of water and methanol into the fuel chamber.The research showed that the microcontroller-based WaI can work correctly when applied tomotorcycles. This system works for injecting water or a mixture of water and methanol into the combustionchamber. Injection is done when the suction valve is open. This condition is known by placing a proximitysensor. On the other hand, the frequency of water or a mixture of water and methanol injection were governedby the microcontroller through the injector.The results showed that the microcontroller-based WaI can work correctly and properly.

Abstract

The purpose of this study wereto determine the effect usage of gasoline heating through a capillary tube which is radial finned in the upper tank of radiator on fuel consumption and exhaust emissions of CO and HC in the engine of Toyota Kijang.This study is experimental. The sample in this study was the machine of Toyota Kijang with machine number 7855290. Free variable of the research is the usage of fuel heating with fin variations on the copper capillar tube consist of copper capillar tube without fin, finned copper capillar tube with the ranges between the fins are 10 mm, 20 mm, and 30 mm and variations of engine speed at 1000 r.p.m., 2000 r.p.m., and 3000 r.p.m. Experimental method to measure the fuel consumption is done by recording the time required for spent fuel 50 cc and exhaust emissions of CO and HC in the engine of Toyota Kijang.The result of this research shows that the average consumption at engine speed 1000 r.p.m. on the normal condition Toyota Kijang has average fuel consumption 32,066×10-3 cc per cycle. In the usage of fuel heating using three copper tubes with the range between the fins is 10 mm fuel consumption by 25,174×10-3 cc per cycle. Fuel consumption decreased by 6,892×10-3 cc per cycle or 21,58%. At engine speed 2000 r.p.m. on the normal condition Toyota Kijang average consumption 38,487×10-3 cc per cycle. In the usage of fuel heating using three copper tubes with the range between the fins is 10 mm fuel consumption by 28,121×10-3 cc per cycle. Fuel consumption decreased by 10,366×10-3 cc per cycle or 26,93%. At engine speed 3000 r.p.m. on the normal condition Toyota Kijang average consumption 36,783×10-3 cc per cycle. In the usage of fuel heating using three copper tubes with the range between the fins is 10 mm fuel consumption by 31,187×10-3 cc per cycle. Fuel consumption decreased by 5,596×10-3 per cycle or 15,21%. The conclusion of this research is the usage of fuel heating using three copper tubes with the range between the fins is 10mm in the upper tank of radiator can reduce the biggest lowers fuel consumption on the Engine of Toyota Kijang 1989.This research also shows that: the usage of fuel heating use 3 finned copper tubes in the upper tank of radiator can reduce the highest level on exhaust emissions of CO and HC in the engine of Toyota Kijang. The different of CO exhaust emission is 2,54 % volume or 85 % while the HC exhaust emission is 139,667 ppm volume or 72 %.

Abstract

The purpose of this research: (1) Investigated the motorcycle exhaust emissions Suzuki Shogun FL 125 SP in 2007 used premium,pertamax,and pertamax plus. (2) Investigated the motorcycle exhaust emissions Suzuki Shogun FL 125 SP in 2007 used variation of compression ratio. (3) Investigated the motorcycle exhaust emissions Suzuki Shogun FL 125 SP in 2007 used interaction premium,pertamax, pertamax plus, and variation of compression ratio.This research was used experimental methods.The research was measurement at the Laboratory of Automotive Mechanical Engineering Education Program, JPTK, FKIP, UNS Surakarta to the address on Ahmad Yani road no. 200 Kartasura. Test of CO and HC exhaust gas emissions was used a gas analyzer type STARGAS 898. The population in this research was a motorcycle Suzuki Shogun FL 125 SP in 2007 and the sample in this research was a motorcycle Suzuki Shogun FL 125 SP in 2007 with engine number: F4A1ID113687.Based on this researchcan be concluded: (1) The measurement premium fuel producedthe lowest emission in CO 3.884% by 9.1:1 compression ratio and the the lowestexhaust gas emission levels in 168 ppmby 9.1:1 compression ratio.
