Abstract
Dalam penerapannya mesin gasoline merupakan salah satu penggerak mula yang cukup banyak pemakaiannya. Indonesia merupakan negara agraris yang sebagian besar penduduknya bekerja bercocok tanam dan termasuk salah satu negara yang menggunakan mesin gasoline stasioner (putaran tetap) sebagai mesin penggerak pompa untuk irigasi maupun petani tambak. Telah banyak penelitian dilakukan seputar karakteristik LPG pada S.I.E.(Spark Ignition Engine). Sebagian besar diantaranya menggunakan metode eksperimental. Kajian secara numerik ini memanfaatkan perangkat lunak Lotus Engine Simulation (LES) sebagai alat bantu utama untuk mengetahui perbedaan unjuk kerja engine. Beberapa hasil yang didapatkan yaitu terjadi perbaikan performa brake torque, brake power, BMEP dan BSFC yang cukup baik pada engine berbahan bakar LPG STD dengan pengaturan AFR 15,5 dan ignition timing 10 BTDC pa da kondisi operasional standar dengan nilai kenaikan masing - masing sebesar +0,11 %; +0,7 %; +0,14 % dan penurunan sebesar - 5,7 %. ========== The application of gasoline engine is one of the prime movers which is much enough of its usage. Indonesia is an agricultural country that some of populations are farmers and one of the countries that use the gasoline engine stationary (fixed rotation) as an engine pump for irrigation and fish farmers. There have been many studies about the characteristics of LPG at SIE (Spark Ignition Engine) Most of them use the experimental method. The numerical study uses software Lotus Engine Simulation (LES) as a tool to know the difference of engine performance. Some of the results produced the improvement performance of brake torque, brake power, BMEP and BSFC are good enough on engines fueled with LPG STD by setting 15.5 AFR and ignition timing 10 BTDC than gasoline-fueled engine at standard operating conditions with the increase in the value of each +0.11%; +0.7%; +0.14% And the decrease of - 5.7%.
