Abstract

Penelitian ini bertujuan untuk mengevaluasi dampak tekanan pompa bahan bakar yang meningkat dan variasi jumlah lubang injektor terhadap kinerja mesin. Seiring dengan perkembangan sistem bahan bakar dari karburator ke injeksi untuk meningkatkan efisiensi bahan bakar, penelitian ini melibatkan tiga tingkat tekanan pompa bahan bakar (2,5 bar, 3 bar, dan 3,5 bar) dan variasi jumlah lubang injektor (3, 6, dan 8 lubang). Kinerja mesin, yang diukur melalui daya dan torsi, dievaluasi melalui metode eksperimental. Hasil menunjukkan pengaruh signifikan dari peningkatan tekanan pompa bahan bakar dan variasi jumlah lubang injektor terhadap kinerja mesin. Daya optimal dicapai pada tekanan pompa bahan bakar 3 bar dengan injektor 6 lubang, menghasilkan 11,63 HP pada 6000 rpm. Torsi terbaik tercatat pada tekanan pompa bahan bakar 3,5 bar dengan injektor 3 lubang, menghasilkan 43,10 Nm pada 3000 rpm. Studi ini menyarankan bahwa jumlah lubang injektor yang lebih tinggi umumnya berkorelasi dengan peningkatan daya dan torsi mesin. Penelitian ini memberikan wawasan berharga untuk mengoptimalkan kinerja mesin melalui konfigurasi tekanan pompa bahan bakar dan injektor yang spesifik, berkontribusi pada kemajuan dalam desain dan efisiensi sistem bahan bakar.
