Abstract
Dalam metode reverse engineering sebuah engine baru
dilakukan sebuah analisa. Salah satu diantaranya adalah mengenai
analisa aliran udara dan gas pada intake cone dan exhaust manifold.
dengan menggunakan CFD tekanan dan kecepatan fluida pada
sistem udara pembakaran dari desain diesel engine 93,2 Kw telah
dianalisis dengan menggunakan CFD. Data-data dari diesel engine
diperoleh dari simulasi prediksi performa engine. Hasil dari simulasi
aliran didapatkan tekanan fluida udara pada intake cone sebesar
1,12 bar, 1,14 bar, 1,16 bar, dan 1,15 bar. Sedangkan tekanan pada
exhaust manifold adalah sebesar 1,6 bar, 1,3 bar, 1,2 bar, dan 1,24.
Pada hasil simulasi kecepatan di intake cone didapatkan data
sebesar 33,5 m/s, 32,9m/s, 34,5m/s, dan 34,29m/s. sedangkan
untukkecepatan pada exhaust manifold adalah sebesar 93,8 m/s,
117,42 m/s, 122,77 m/s, dan 202 m/s. maka dari hasil analisa aliran
fluida udara dan gas sesuai dengan kebutuhan engine untuk udara
pembakaran dan gas untuk memutar turbocharger diesel engine.
============================================================
In the method of reverse engineering a new engine
performance is analyzed. One of them is about the analysis of air
and gas flow on the intake cone and exhaust manifold. By using
CFD pressure and fluid velocity of the combustion air system
93.2 Kw diesel enginehas been analyzed by using CFD. The data
of diesel engine performance prediction obtained from engine
simulation. The result obtained from the simulation flow fluid
pressure of air on intake cone of 1.12 bar, 1.14 bar, 1.16 bar,
1.15 bar. While the pressure in exhaust manifold is equal to 1.6
bar, 1.3 bar, 1.2 bar, 1.24 bar. In the simulation result in the
intake cone velocity data obtained at 33.5 m/s, 32.9 m/s, 34.5
m/s, and 34.29 m/s. Whereas for the velocity of the exhaust
manifold is equal to 93.8 m/s, 117.42 m/s, 122.77 m/s, and 202
m/s. Then the result of the analysis of fluid flow of air and gas in
accordance with the needs of the engine for combustion air and
gas to rotate the turbin turbocharger diesel engine.
