Abstract

The purpose of this study was to determine how much influence changes in pickup coil and engine speed on fuel consumption in a 150 cc engine. The method used in this study is the experimental method or direct experimental method by varying the pickup coil position and engine speed. There are several conclusions from this research, namely: 1) The higher the engine speed for each time advancing the pickup coil position forward 1mm, forward 2 mm , and going forward 3 mm more wasteful of fuel consumption. 2) Compared to the position of standard pick up coil with 1mm, 2mm, and 3mm pick up coil, the fuel consumption is more wasteful. 3) Comparison between the 2mm and 1mm pickup coil times is more wasteful of fuel consumption than the standard pickup coil positions. 4) Compared between the 1 mm backward pickup coil with the standard condition, the fuel consumption is more efficient when the pickup coil retreated by 1 mm. 5) At the time of retreating the pick up coil the higher the motor rotation, the more efficient fuel consumption.

Abstract

The purpose of this study is to distinguish exhaust gas emissions (CO and HC) from a 125 cc motorcycle mixed with Gasoline and pertalite (75% -25%) with Gasoline fuel. The method used is the expriment method, namely by conducting a direct experiment. The material and tools used are a supra x 125 motorbike, gas analyzer, Gasoline, pertalite. The results of the research are obtained for a mixture of pertalite and Gasoline (75% -25%). For 1000 rpm rotation, the CO price is 3.0 and the price HC is 120, for round 2000 rpm the price of CO is 2.95, and the price of HC is 112, for 3000 rpm the price of CO is 2.87, and the price of HC is 110. for 4000 rpm, the price of CO is 2.65 and HC price is 100. The research results can be for mixture (50% -50%). For 1000 rpm rotation, CO price is 3.15 and HC HC price is 130, for 2000 rpm round, CO price is 3.01, and price HC is 124, for 3000 rounds rpm CO is 2.96, and HC price is 120, for 4000 rpm rotation, CO price is 2.75, and HC is 119. Research result (100%). For 1000 rpm rotation CO price is 4.1, and HC price is 160, for round 2000 rpm, price of CO 3.95 and HC is 152, for round 3000 rpm, price of CO is 3.70, and price of HC is 145, for rotation of 4000 rpm, the price of CO 3.55 and HC is 140. In conclusion, the higher the rotation, the greater the HC both the mixture of gasoline and pertalite and gasoline are smaller, while for CO, if the rotation is greater then the percentage is smaller for a mixture of gasoline and pertalite, and pertalite the price is more expensive.

Abstract

The purpose of this research is to differentiate exhaust emissions (CO and HC) of a motorcycle fueled by a mixture of firstx and ethanol (95-5%) with pertalie fuel. The method used is the expriment method, namely by conducting direct experiments. The materials and tools used are a supra x 125 motorcycle, gas analyzer, firstx, ethanol, pertalite. The results of the study were obtained for a mixture of firstx and ethanol (95-5%) for a rotation of 1000 rpm, the CO price was 0.67%, and the HC price was 203 ppm, for a rotation of 2000 rpm the CO price was 0.47%, and the HC price was 188.3 ppm, for a rotation of 3000 rpm the CO price was 0.27%, and the HC price was 87.6 ppm. In conclusion, the higher the rotation, the greater the HC of both the firstx and ethanol mixture and the premium price is smaller, while for CO, if the rotation is greater, the percentage is smaller for the firstx and ethanol mixture, and the premium price is greater.

Abstract

Motorized vehicles are generally equipped with a driving engine which functions as a driver for the car. Motorized vehicles have engines consisting of one cylinder, two cylinders, three cylinders, and so on, and all of them require air as a medium for burning fuel in the combustion chamber to produce power to drive the vehicle. Motorized vehicles, both at sea and on land, operate at different air temperatures in all corners of the earth. This research was carried out by varying the air temperature entering the combustion chamber. The intended temperatures are 20oC, 25oC, 30oC, 35oC, and 40oC, and what will be examined is fuel consumption, HC, and CO exhaust emissions. The research results show that air temperatures from 20 to 40 degrees do not significantly affect fuel consumption or HC and CO exhaust emissions.

Abstract

The purpose of this study is to find out how much influence the replacement of lower resistor resistance values ​​(6 and 8 0hm) with rotations of 1000, 2000, 3000, 4000 rpm has on battery charging, and to find out how much influence the replacement of higher resistor resistance values ​​(13 and 15 0hm) with rotations of 1000, 2000, 3000, 4000 rpm has on battery charging. From the background, the regulator charging system is a system that is very much needed in four-wheeled vehicles to meet the needs of battery current when the engine is running, because when the engine is running, especially gasoline engines, it really needs battery current for the continuity of the system to work, the method used in this study is the literature study method and direct testing method as well as recording the results and analyzing them theoretically based on observations. The results obtained are experimental research on the resistor resistance value below the standard size, the charging voltage at 1000 rpm engine speed is above the battery voltage, if the engine speed is increased higher then overcharging will occur (excessive charging) then the battery will be damaged where the charging voltage at idle speed is sufficient for the battery voltage, and does not exceed the battery limit voltage when the rotation reaches 4000 rpm, which is 14.5 volts, while the battery limit voltage is 14.8 volts.
