Abstract

The growth of vehicles in Indonesia is dominated by motorcycles. The current compression ratio of the motorcycle is above 9 : 1. Types of gasoline on the market have octane number of 88, 90, 92. The purpose of this study is to analyze engine and combustion performance, noise and vibration, and emissions from gasoline type with a compression ratio of 10 : 1. This study was used engine with 1 cylinder and 4 strokes, sound level meter to measure noise, VibexpertII with acceleration mode for vibration measurement, AGS-688 for exhaust emission test. The test results showed that the break power of all fuels tends to be constant and the smallest SFC is an octane number of 92 (ON 92). The combustion performance of ON 92 also tends to be stable, but noise and vibration of ON 92 are higher. CO and HC emissions of all fuel tend to be constant.

Abstract

The use of electric vehicles (EVs) has been rapidly growing, encompassing both fully electric and converted models. A key component of EVs is the battery. This study focused on designing and testing a battery pack for a converted EV named BEATRIX, employing both analytical and experimental methods. The battery, constructed with lithium-ion cells and equipped with a smart management system, achieves a capacity of approximately 72-83V and 19.2Ah. It measures roughly 120mm x 120mm x 330mm and weighs about 5 kg. Testing results indicate that during the discharging process, the voltage and capacity decrease to 75V and 11.5Ah, respectively, while the electric current remains stable at around 4.83A and the temperature is held constant at 32°C. During the charging process, the voltage and capacity increase to 82.2V and 17Ah. Initially, the electric current stabilizes at around 4.38A for 10 to 70 minutes, then gradually decreases to 1.8A at the 100-minute mark, with the temperature remaining steady at 33°C
