ABSTRAK

Semakin mahalnya harga BBM Bahan Bakar Minyak untuk bahan bakar water pump membuat BBM tidak lagi efisien. Sebagai langkah awal konversi adalah mengubah sistem pemasukkan bahan bakar bensin pada water pump dalam hal ini water pump CS4 123 cc yang awalnya berbahan bakar bensin mencoba dibandingkan dengan full LPG. Dalam melakukan perbandingan unjuk kerja water pump engine cs4 123 cc berbahan bakar bensin dan LPG menggunakan Lotus Engine Simulation LES maka diperlukan spesifikasi water pump engine kohler cs4 yang didapat darimanual book dari pabrik. Kemudian spesifikasi yang telah didapat di input kedalam software tersebut sehingga bisa didapat hasil data Brake Power Brake Torque Brake Mean Effective Presure BMEP Brake Spesifik Fuel ConsumptionBSFC dan Volumetric Efficiency. Setelah dilakukan simulasi dan verifikasi perbandingan unjuk kerja engine cs4 123 cc berbahan bakar bensin pada keadaan stoikiometri gasoline 146 dan LPG pada keadaan stoikiometri 155. Performa engine berbahan bakar LPG dapat dimaksimalkan dengan cara pengaturan AFR pada keadaan stoikiometri LPG yaitu 12 dan pengaturan ignition timing 10 BTDC. Dengan pengaturan tersebut unjuk kerja mengalami kenaikan dengan kenaikan brake torque 3.5 brake power 3.6 BMEP 4.8 dan penurunan sebesar BSFC -217 .


ABSTRACT

Increasingly high price of fuel fuel oil to fuel water pump making the fuel is no longer efficient. As a first step in the conversion is to change gasoline fuel intake system on the water pump in this case water pump KOHLER CS4 cc petrol which initially berbahn try compared with full LPG. In comparison to the performance of the engine water pump kohler cs4 123 cc petrol and LPG using Lotus Engine Simulation Les then the required specifications kohler engine water pump cs4 book darimanual obtained from the factory. Then the specifications that have been obtained at the input into the software so that the data can be obtained outcome Power Brake Brake Torque Brake Mean Effective Presure BMEP Brake Specific Fuel Consumption BSFC and Volumetric Efficiency. After analysis and validation of numerical perbnadingan performance cs4 kohler engine water pump gasoline with LPG using software Lotus Engine Simulation LES found the following results brake torque brake power BMEP and BSFC LPG-fueled overall can be maximized by how ignition timing ideal conditions ie 10 BTDC and AFR settings at state 12 LPG 1 with the increase of each - amounting to 3.36 3.36 9.3 And a decrease of -4.90.
