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

Abstract

Indonesia is currently experiencing a national electricity crisis. It is ironic that a positive economic growth rate in recent years the availability of electrical energy that is driving the economy in critical condition. Rotating blackouts caused an outcry from the public and business circles because of disruption of their activities. Given the frequent blackouts, people are essentially relied to the role of the generator as a source of alternative electrical energy. Genset used generally use gasoline and diesel fuel. People often experience a loss in this case, both in terms of economy and also a lot happening even other losses as a result of the shortage of power supply in an area, even likely also an area that is not served by the electricity grid at all. As a power generator producing electricity by using gas as an energy source have been widely used by the public. The gas can be either LPG (Liquiefied Natural Gas), Natural Gas, or CNG (Compressed Natural Gas). The price of gas is still quite low compared to other fossil fuel such as diesel or gasoline. Besides gas is an environmentally friendly energy. This study will assess the comparative advantages of what some using LPG gas fuel is the engine generator set. Research question include testing motor power, torque, the average effective pressure, fuel flow and thermal efficiency. After testing with a round of 4000 rpm the engine power, torque, and the average effective pressure is greater when using LPG gas fuel than when using gasoline fuel. And in terms of gasfueled gensets economic LPG is more economical than using gasoline fuel generators.
