ABSTRAK

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 932 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 112 bar 114 bar 116 bar dan 115 bar. Sedangkan tekanan pada exhaust manifold adalah sebesar 16 bar 13 bar 12 bar dan 124. Pada hasil simulasi kecepatan di intake cone didapatkan data sebesar 335 ms 329ms 345ms dan 3429ms. sedangkan untukkecepatan pada exhaust manifold adalah sebesar 938 ms 11742 ms 12277 ms dan 202 ms. maka dari hasil analisa aliran fluida udara dan gas sesuai dengan kebutuhan engine untuk udara pembakaran dan gas untuk memutar turbocharger diesel engine


ABSTRACT

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 ms 32.9 ms 34.5 ms and 34.29 ms. Whereas for the velocity of the exhaust manifold is equal to 93.8 ms 117.42 ms 122.77 ms and 202 ms. 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.
