“…Meanwhile, increasing the camshaft duration on Performance and Exhaust Gas Emissions on the Sinjai 650 cc Engine. Simulation results comparing the performance of the best SINJAI 650 cc SOHC port fuel injection engine using a 260˚ camshaft, with an increase in torque of 0.908%, power of 0.908%, bmep of 0.908%, thermal efficiency of 0.626%, volumetric efficiency of 1.003% and a decrease in bsfc of 0.252% of the camshaft standard in the rotation range of 4000-6000 rpm [20], [21]. Apart from that, variations in ignition performance affect engine performance.…”

This study aims to evaluate the effects of increasing fuel pump pressure and varying the number of holes in the injector on engine performance. The fuel system in the engine has evolved from carburettor to injection system to improve the efficiency of fuel usage. In this study, the fuel pump pressure was increased to three levels, namely 2.5 bar, 3 bar, and 3.5 bar. In addition, variations in the number of holes in the injector were also tested using 3-hole, 6-hole, and 8-hole injectors. Engine performance was evaluated based on the power and torque produced. The research method used is experimental with power and torque measurements as engine performance data. The results showed that increasing fuel pump pressure and varying the number of holes in the injector had a significant effect on engine performance. Increasing the fuel pump pressure to 3.5 bar results in an increase in engine power and torque. The best power test results were obtained at a fuel pump pressure of 3 bar with a combination of 6-hole injectors, producing a maximum power of 11.63 HP at 6000 rpm engine speed. While the best torque test results were obtained at a fuel pump pressure of 3.5 bar with a combination of 3-hole injectors, producing a maximum torque of 43.10 Nm at 3000 rpm. The variation in the number of holes in the injector shows that the use of injectors with more holes tends to increase engine power and torque.
