Abstract

To support teaching and learning activities at Akmil, many diesel-engined trucks are needed that use diesel. Considering that diesel is not a renewable resource, biodiesel is a more environmentally friendly alternative, because it is produced from vegetable or animal oil. Testing the performance of diesel engines with biodiesel and diesel at various speeds shows differences, although not significant. This can be used as a guideline in selecting fuel, especially for TNI AD vehicles, and it is hoped that biodiesel can be widely known as an alternative fuel.

Abstract

The ignition coil in a motorcycle functions to increase the electrical voltage from a 12-volt battery to thousands of volts, which is then delivered to the spark plug to generate a spark for the combustion process. This study analyzes the effect of replacing a motorcycle ignition coil with a car ignition coil on fuel consumption. The experiment was conducted using several variables, including engine speed, fuel consumption time, and power output. The results indicate that an engine using a car ignition coil produces greater power than one using a motorcycle coil, while also being more fuel-efficient. This is due to the stronger and more efficient ignition provided by the car coil, which enhances combustion efficiency and reduces fuel wastage

Abstract

Gears function to transmit high power and precise rotation through interlocking teeth. Gears are superior to other transmission systems as they are more compact, capable of transmitting large power with high efficiency, and have a minimal risk of slipping. Additionally, gears can withstand higher loads and allow for speed variations as needed. One commonly used type is the bevel gear, where the pitch surface forms a cone with its apex at the intersection of the shaft axes. Straight bevel gears are the easiest to manufacture and frequently used, although they produce significant noise due to their low contact ratio. Other types of bevel gears include spiral bevel gears, helical bevel gears, and hypoid gears, each with unique characteristics and advantages in transmission systems.

Abstract

To support high mobility and varied terrain, vehicles must have optimal engine performance, especially in the clutch system, which is prone to slipping due to clutch lining wear, increasing the risk of accidents. This study analyzes the wear level of Suzuki Katana clutch linings by comparing KW 1 and KW 2 through hardness, wear, and carbon content tests. The results indicate that KW 1 has a hardness of 251.34 kg/mm², higher than KW 2, which is only 67.82 kg/mm². The wear value of KW 1 is 0.003×10⁻⁴ mm³/kg.m, lower than KW 2 at 0.0086×10⁻³ mm³/kg.m. The carbon content in KW 1 reaches 44.0739%, higher than KW 2 at 32.3462%. These findings show that the higher the hardness of the clutch lining, the lower its wear rate, making KW 1 a better choice as it is more durable and resistant to wear.
