The most critical component of a motorcycle's combustion process is the spark plug, which fires sparks for the ignition system. In this research, the performance of several spark plug electrode gap diameters and materials was varied to detect how much they affected engine performance, fuel consumption, and emissions. Engine testing was conducted on a 110-cc four-stroke engine. Nickel material spark plugs with a gap dimension of 0.9 mm, platinum material spark plugs with a gap dimension of 0.8 mm, iridium material spark plugs with a gap dimension of 0.7 mm, and two types of ignition coils. The test findings indicated that there is a spark plug with an appropriate gap for engine performance in the form of torque and power in the B2 configuration, which has a gap of 0.8 mm. Increasing the spark plug gap produces a loss in engine performance, but it also increases it. There is an optimal point of fuel consumption in configuration B2, where raising the spark plug gap decreases fuel consumption while increasing the spark plug gap increases fuel consumption. Exhaust emissions likewise experience an optimal point in configuration B2, when exhaust emissions rise as long as the spark plug gap is increased once more, HC and CO levels decrease with an increasing spark plug gap. To examine the study on the impact of spark plugs with electrode gaps and ignition coils on engine performance, fuel consumption, and emissions. This can provide insight into a reference technique for using spark plugs and ignition coils.

This article is a descriptive review study on palm oil biodiesel and its comparison with diesel fuel. Crude Palm Oil (CPO) is the best raw material for biodiesel because it has similar fuel specifications to diesel fuel. Fuel specifications according to American Standard Testing and Material (ASTM) and European Standard (EN) specifications are kinematic viscosity, density, and flash point. Palm oil biodiesel has a higher Brake Specific Fuel Consumption (BSFC) value and a lower Brake Thermal Efficiency (BTE) value compared to diesel. Palm oil biodiesel has higher NOx emissions, but lower HC and CO emissions, than diesel. In addition, palm oil biodiesel can be used in diesel engines with little or no modification. It has higher density, cooler flow problems and lower calorific value. Biodiesel can be blended with diesel and used in various concentration ratios to produce biodiesel blends that have properties that comply with international standards on diesel engine fuel and emissions, resulting in improved diesel engine performance and reduced emissions. The B20 and B30 biodiesel blend compositions are the best blend compositions based on the balance between engine efficiency and emission reduction due to the optimal balance between engine performance and environmental benefits. The B20 and B30 biodiesel blends show significant reductions in CO and HC emissions, achieving reductions of about 10% to 25% compared to diesel. The decrease in BTE and increase in BSFC are still proportional, so they do not compromise overall fuel efficiency too much.

In addition to adding ferrite beads to the ignition coil, this study attempts to examine the effects of different spark plugs and ignition coils. Ferrite beads are employed to mitigate electrical noise and enhance electrical efficiency. This research facilitates the examination of engine performance and exhaust emissions, thereby offering insight into the combustion process within the combustion chamber. This study used a 4-stroke Otto engine with a displacement of 110 cc, powered by RON 92 gasoline. We utilize three types of spark plugs: Denso U22FS-U, NGK 14 mm, and Iridium IU27. Two varieties of ignition coils are employed: PCX 150 and COL9001, supplemented by ferrite beads. Dynotes are utilized to assess engine performance, while gas analyzers are employed to evaluate exhaust pollutants. The criteria examined for engine performance include torque and power, while exhaust emission parameters consist of CO, CO2, O2, and HC. The findings indicate that the NGK 14-mm spark plug, when paired with a COL9001 ignition coil and supplemented with a ferrite bead, achieves a peak torque of 7.67 Nm at 6514.42 rpm and a maximum power output of 5.73 kW at 72813.93 rpm. This setup yields minimal emissions and favorable fuel consumption when it is implemented. This study's findings offer significant insights and references for tactics including spark plugs, ignition coils, and ferrite beads.

The development of technology in vehicles continues to be developed to meet human needs and be environmentally friendly. One technology that is still being developed is the use of spark plugs and coils. The function of spark plugs in motorized vehicles is to spark sparks caused by the electric voltage generated by the coil. Various kinds of coil produce different high voltage. This research uses a Yamaha Vixion 150 CC, 1 cylinder, four-stroke motorcycle. The research was conducted by providing spark plug and coil variations including standard U24ESR-N (Denso) spark plugs, 0.4mm Iridium spark plugs, and Brisk Silver spark plugs. Coil variations were also given including 3C1 H2310 spark plugs and Uma Racing spark plugs. The data taken includes a comparison of emissions produced, torque, and power. The highest power at RPM 8500 was generated by the U24ESR-N spark plug (Denso) with the use of the Uma Racing coil type of 8.69 kW. Spark plug and coil variations will also determine torque. The highest test on the use of Uma Racing coil and Brisk Silver spark plug at 6500 RPM engine speed produces a value of 9.35 Nm. The results also show changes in emissions produced such as CO2, CO, HC, and O2 emissions. The use of 0.4mm Iridium spark plugs with 3C1 H2310 coil and Brisk Silver spark plugs with 3C1 H2310 produces high voltage resulting in higher CO and HC gas production

This research explores the use of oil palm empty fruit bunch waste fibers as an environmentally friendly reinforcement material for composite applications, aiming to replace conventional materials. The fabrication process utilized empty fruit bunch fibers, resin, and polylactic acid (PLA), with components produced using 3D printing technology. Mechanical properties were evaluated through tensile testing (ASTM D3039), compressive testing (ASTM D695), and Vickers microhardness testing (ASTM E384). The results showed an average maximum tensile strength of 8.18 MPa, while compressive testing yielded a maximum strength of 3.95 MPa. Vickers hardness values ranged from 19.53 to 29.04, with an average of 25.73. These findings highlight the potential of empty fruit bunch fiber composites as an alternative material that supports waste reduction and sustainability in the palm oil industry. However, further optimization of fiber fraction and surface treatment is needed to improve mechanical performance. This study not only contributes to scientific knowledge but also opens opportunities for sustainable material innovation in engineering applications

Advanced materials are used in thermoelectric generator (TEG) technology to turn heat into electricity using the Seebeck effect, which helps make better use of heat sources. The Seebeck effect is a result of the temperature disparity that exists between the two surfaces of the TEG. The configuration utilized in this investigation comprises several primary components, including the water block, thermoelectric, heat exchanger plate, and heater plate. The water block is positioned on the cold surface side of the thermoelectric to optimize the cooling process, while the heater plate is positioned on the surface side to facilitate the heating process. Initially, we position the heater plate to avoid direct contact between the heated surface side and the material plate. The plates consist of both copper and aluminum elements. This is done to facilitate the identification of the configuration systems, specifically TEG A (copper) and TEG B (aluminum). The research findings indicate that the TEG B configuration system, when subjected to a heating rate, yields superior voltage, current, and power outputs.
