Abstract

Kendaraan bermotor saat ini sudah banyak digunakan. Manusia membutuhkan kendaraan bermotor untuk transportasi dan menunjang aktivitas. Penggunaan kendaraan bermotor secara terus menerus membutuhkan bahan bakar yang banyak. Pengaruhnya yaitu menipisnya cadangan minyak bumi dan meningkatkan emisi gas. Seiring perkembangan zaman, manusia pun membutuhkan adanya inovasi peningkatan tenaga pada engine. Dengan adanya teknologi VVT-i dimana teknologi pengaturan sistem kerja katup pemasukan bahan bakar secara elektronik baik dalam hal waktu maupun ukuran buka tutup katup sesuai putaran engine sehingga meningkatkan tenaga engine, hemat bahan bakar, dan ramah lingkungan. Pada Tugas Akhir ini, dilakukan studi penambahan VVT-i pada sepeda motor Honda CBR 250 R. Pemodelan awal Engine sepeda motor Honda CBR 250 R akan disimulasikan dengan software Lotus Engineering. Setelah itu, dengan penambahan pemodelan VVT-i pada Honda CBR 250 R bagaimana performa engine berupa Engine speed vs Brake Power, Engine Speed vs Brake Torque, Engine Speed vs BMEP (Brake Mean Effective Pressure), Engine speed vs BSFC (Brake Specific Fuel Consumption), dan Engine Speed vs Efisiensi Volumetric. Dari hasil simulasi, setelah penambahan VVT-i didapatkan adanya perubahan performa engine pada sepeda motor Honda CBR 250 R yaitu pada Brake Power 7 dari 11 variasi engine speed rata-rata kenaikannya sebesar 0,04 kW. Pada Brake Torque 8 dari 11 variasi engine speed rata-rata kenaikannya sebesar 0,07 Nm. Pada BMEP (Brake Mean Effective Pressure) 7 dari 11 variasi engine speed rata-rata kenaikannya sebesar 0,04 bar. Pada BSFC (Brake Specific Fuel Consumption) 7 dari 11 variasi engine speed rata-rata penurunan sebesar 0,184 g/kWhr. Pada Efisiensi Volumetric 8 dari 11 variasi engine speed rata-rata kenaikannya sebesar 0,275 % . ============================================================================== Motor vehicles are now widely used. Humans need a vehicle to transport and support the activities. The use of a motor vehicle is continuously requires a lot of fuel. Its influence is depletion of oil reserves and increase emissions. Along with the times, man also requires innovation increase in engine power. With the VVT-i technology where technology work system settings valve electronic fuel intake both in terms of time as well as the size of the opening and closing of the valve according to the engine speed increases engine power, fuelefficient, and environmentally friendly. In this final project, conducted studies on the addition of VVT-i motorcycle Honda CBR 250 R. Modeling beginning Engine motorcycle Honda CBR 250 R will be simulated with software Lotus Engineering. After that, with the addition of modeling VVTi on the Honda CBR 250 R how performance engine such as engine speed vs. Brake Power, Engine Speed vs. Brake Torque, Engine Speed vs. BMEP (brake mean Effective Pressure), Engine speed vs. BSFC (Brake Specific Fuel Consumption ), and Engine Speed vs. Volumetric Efficiency. From the simulation results, after the addition of VVT-i got the change of engine performance on a motorcycle Honda CBR 250 R is the Brake Power 7 of 11 variations of the average engine speed increase of 0.04 kW. Brake Torque on 8 of 11 variations of the average engine speed increase of 0.07 Nm. At BMEP (Brake Mean Effective Pressure) 7 of 11 variations of the average engine speed increase of 0.04 bar. At the BSFC (Brake Specific Fuel Consumption) 7 of 11 variations of the average engine speed decrease of 0.184 g / kWhr. In the Volumetric Efficiency 8 of 11 variations of the average engine speed increase of 0.275%.
