Abstract

Torak adalah salah satu bagian penting dalam proses pembakaran pada mesin diesel, bagian piston terdiri dari dua yaitu Piston Head dan Connecting Rod, dimana kepala torak dibagi lagi menjadi tiga bagian, yaitu mahkota torak, ring torak, dan pin torak. Tugas akhir ini ingin membuktikan mana yang lebih efektif dalam memodifikasi bentuk mahkota torak TCC pada mesin diesel satu silinder empat langkah dalam mengukur tingkat kebisingan dan getaran. Untuk mengukur tingkat kebisingan dan getaran, beberapa percobaan akan dilakukan. Salah satu caranya adalah dengan menggunakan software yang bisa mempermudah pengukuran dengan menggunakan simulasi. Dalam simulasi dapat mengukur tingkat kebisingan dan getaran dengan menggunakan alat-alat dalam aplikasi yang sama seperti aslinya. Luasan torak sangat terpengaruh terhadap proses pembakaran, dengan semakin besarnya luasan torak maka menghasilkan ledakan semakin besar yang mengakibatkan dan menghasilkan tekanan yang tinggi pula hal itu berbanding lurus dengan tingkat kebisingan dan getaran pada mesin diesel tersebut. Setelah semuanya diukur, maka penulis membandingkannya dengan performa mesin dan memberikan hasil maksimal antara tingkat kebisingan, getaran dengan kinerja mesin. Hasilnya dengan menggunakan torak case 4(+1) yang memiliki luasan lebih besar mengalami tingkat kebisingan paling tinggi menggunakan bahan bakar B30 ataupun HSD. Pada kondisi beban, dengan beban 50% tingkat kebisingan pada torak case 4(+1) mengalami tingkat kebisingan paling tinggi menggunakan bahan bakar B30 ataupun HSD. Pada Analisa getaran mesin diesel, tingkat getaran paling tinggi terjadi pada RPM yaitu 2200 menggunakan bahan bakar B30 atupun HSD, dan tingkat getaran terendah terjadi pada RPM 1600 menggunakan bahan bakar B30 maupun High Speed Diesel (HSD). =========================================================== The piston is one of the important parts in the combustion process in a diesel engine, the piston part consists of two namely the piston head and connecting rod, where the piston head is divided again into three parts, namely the piston crown, piston rings, and piston pins. This thesis wants to prove which is more effective in modifying the TCC piston crown shape on a four-Stroke one-cylinder diesel engine in terms of noise and vibration levels. To measure noise and vibration levels, several experiments were carried out. One way is to use an application that can help make measurement easier is to use the Simulation. The Simulation can measure the level of noise and vibration level by using the tools in that application the same as the original. The piston area is very influential on the combustion process, with the greater piston area, the resulting explosion is greater which results in and produces a high pressure also it is directly proportional to the level of noise and vibration in the diesel engine. After everything is measured, then we compare it with the engine's performance and give maximum results between the level of noise, vibration with engine performance. The result is using a piston case 4 (+1) which has a larger area experiencing the highest noise level using B30 Diesel Fuel or High Speed Diesel (HSD) Fuel. Under load conditions, with a 50% load the noise level on piston +1 (Case 4) experiences the highest noise level using B30 Diesel Fuel or High Speed Diesel (HSD) Fuel. In the diesel engine vibration analysis, the highest vibration level occurs at the RPM of 2200 using B30 Diesel Fuel or High Speed Diesel (HSD) Fuel, and the lowest vibration level occurs at RPM 1600 using B30 Diesel Fuel or High Speed Diesel (HSD) Fuel.
