Abstract

The increasing number of motorcycles in Indonesia, exceeding 125 million units in 2022, reflects the high demand for efficient and environmentally friendly vehicles. This trend drives the advancement of combustion system technology, notably the shift from carburetors to Electronic Fuel Injection (EFI). EFI is an electronically controlled fuel delivery system designed to optimize combustion through precise control of ignition timing and fuel injection duration. This system has proven effective in improving engine efficiency and reducing exhaust emissions. However, most mass-produced motorcycles are still equipped with non-programmable ECUs, limiting tuning flexibility. This study evaluates the use of an Arduino-based programmable ECU as a more adaptive alternative. Experiments were conducted on a Honda Vario 110cc FI, varying ignition timing (+2°, +4°, +6°, +8°, +10° BTDC) and fuel injection duration (+5%, +10%, +15%) using Pertamax RON 92 fuel. The results showed an 8% increase in maximum torque (16.98 N.m) at +4° and +5% configuration, and a 3% increase in maximum power at +2° and +10%. The lowest HC and CO emissions were recorded at +2° and +5%, with reductions of 44% and 41%, respectively. The Arduino-based ECU effectively enhances engine performance while maintaining emission efficiency.

Abstract

Speed and accuracy of workmanship are important supporting factors for business actors operating in the service sector. The availability of adequate supporting equipment can increase work productivity and can reduce the risk of work accidents that can endanger the surrounding environment. Technological developments in the automotive industry always provide innovations. Even though it is like that, it still doesn't escape the new problems that accompany it. In the process of replacing a car clutch lining, the application of knowledge about lifting aircraft is very necessary. Differences in the load capacity of car engines that exceed human strength capacity require the use of tools according to specifications. The addition of a hydraulic system to the machine support can provide lifting power that is greater than the power produced by mechanics in lifting or holding loads that exceed their capacity. Apart from that, implementing a culture of occupational health and safety is important to realize workforce welfare. What is not expected when repairing a car's clutch lining is a shift in the load support of the car's engine which can cause damage to other components and can even endanger mechanical safety. The property of magnets that can attract metal objects can be used to improve K3 in the automotive industry as an effort to prevent engine supports from shifting position when repairs are carried out on car clutch linings.
