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%.
