Injection system design, Power, Torque, Exhaust emissions, Fuel consumptionAbstract
This research discusses the design of an injection system for 4-stroke motorcycles, aiming to reduce harmful substances in exhaust emissions by changing the conventional system to an EFI system. In addition, this study also aims to determine how much impact the application of the EFI system on a 4-stroke motorcycle has on torque and power, as well as how much exhaust emissions and fuel consumption are produced after the application of the EFI system. The method used in this research is experimentation. This activity was carried out in 3 test locations, namely at the FT UNP automotive workshop, Teqleck Speedshop, and the straight line of the Minangkabau Airport highway along 1 km. The results showed that the power generated by the designed EFI system decreased by 4.33% or 0.23 kW. Torque also decreased by 6.95% or 0.57 kW. In addition, the HC exhaust emission content decreased by 394.58% or 365.66 ppm, the CO content decreased by 39.13% or 0.63%, and the 〖CO〗_2 content in the exhaust emissions of the 4-stroke motorcycle converted to the EFI system increased by 68.99% or 2.67%. Finally, fuel consumption is more efficient, increasing by 31.85% or 21.98 Km/L.
