Abstract

Penulisan ini bertujuan untuk melakukan Perhitungan Ulang (Rekalkulasi) mesin Diesel 4 tak 4 silinder. Mesin yang digunakan memiliki spesifikasi mesin Mitsubishi L300 Diesel 4 tak 4 silinder dengan tahun pembuatan 1995, mesin diesel yang digunakan ini berpendingin air, dengan mekanisme katup SOHC, isi silinder 2477cc, ukuran Bore x Stroke adalah 91.1 x 95.0, perbandingan kompresi 21 : 1, dan memiliki daya mesin sebesar 74 PS/4200 rpm. Laporan ini mencakup hasil pengukuran-pengukuran komponen mesin diesel L300 antara lain, kepala silinder, blok silinder, silinder liner, torak, batang torak, ring kompresi, ring oli, poros engkol, poros nok, katup, pegas katup, dan rocker arm. Dari pengukuran tersebut dapat disimpulkan bahwa beberapa komponen masih layak untuk dipakai tetapi ada sebagian komponen harus diganti, karena sudah tidak memenuhi standar kelayakan. Rekalkulasi dilakukan dengan cara memasukan data hasil pengukuran ke dalam formula-formula antara lain formula menentukan efisiensi, daya dan kebutuhan bahan bakar. Untuk sistem pendinginan yang dipakai pada mesin ini adalah jenis sistem tekan. Untuk system pembakarannya menggunakan pompa tipe roda gigi. Kata kunci : daya, mesin diesel, efisiensi, rekalkulasi, sistem pendinginan, sistem bahan bakar. The writing is aims to perform calculation (Recalculation) Diesel engine 4 stroke 4 cylinder. The machines that are used have the engine specifications of Mitsubishi L 300 Diesel 4 stroke 4 cylinder with years of manufacture 1995, diesel engine used is water-cooled, SOHC valve mechanism, with the volume of the cylinder size 2477cc, Bore x Stroke was 91.1 x 95.0, compression ratio 21 : 1 and have the engine power of 74 PS/4200 rpm. The report includes the results of measurements of L300 diesel engine components among others, cylinder head, cylinder block, cylinder liner, piston, connecting rod, compression ring, oil ring, crankshaft, camshaft, valves, valve spring and rocker arm. From these measurements, it can be concluded that some components are still worthy to wear but there are some components should be replaced, because it does not meet the eligibility standards. The recalculation done by entering data measurement results into formulas, among others the formula determining the efficiency, power and fuel requirement. For the air cooling system to use the engine is full internal forced-feed system. For the fuel system to use oil pump gear type. Key words: power, diesel engine, efficiency, recalculation, air cooling system, fuel system.
