Analisa Unjuk Kerja Motor Bakar 4 Langkah dengan Menggunakan Bahan Bakar Bensin dan Gas (LPG) (Daya: 3 HP)

Abstract

Energy reserves of fuel oil (BBM) dwindling while the need is increasing. The alternative solution is to use gaseous fuels such as LPG (Liquid Petroleum Gas) which is enough natural gas reserves in Indonesia. One of the concrete steps to increase the use of CNG is through modifications assessment gasoline generator engine to be converted to use gas fuel. Modifications that have been made are adding the venturi mixer as a mixing mechanism between air and fuel. With the research is expected to be a new science later on, and also the public can better optimize for LPG gas which is not only for cooking but also for as a fuel for internal combustion engines in the future. From the results of this study, then performed a comparative analysis of the performance of the engine generator set using materials premium and LPG with constant testing speed. Examination performed include motor power, generator power, torque, the average effective pressure, specific fuel consumption and thermal efficiency. After performing the measurement and analysis of comparative parameters of performance, at a constant speed of 4500 rpm economical value using gasoline fuel compared with using LPG fuel is 33%. From these results it can be seen that the engine generator with fuel LPG is more economical than using a generator with gasoline because it has a higher efficiency. For the future is expected for research using more fuel-efficient and better streamlined, such as bio-gas from animal waste or others. Can also for the development of the converter on the LPG gas engine generator set, such as the addition of electronic devices supplier of fuel into the engine.
