Abstract

The fuel gas (LPG) is natural gas that has a sizable reserves in Indonesia. With the utilization of gas fuel is expected the problem of energy needs and environmental pollution can be solved. Gasoline engine can be operated by using LPG gas fuel, Nevertheless, the performances of gasoline engine is decrease when it using LPG. This performance reduction is caused by the different characteristics of the two fuels. One way to improve the performance of these machines is to adjust the ignition timing so that the ignition timing is more appropriate with the characteristics of LPG gas and gasoline. One way to improve gasoline engine performance that used LPG gas fuel by controlling ignition timming more accurate. Controlling ignition timming is done by sliding angle position on pulser to get ignition timming accurately. The result of test indicated that usage of LPG as fuel on single cylinder gasoline engine result dropping of power till 25% than gasoline power. While value of BSFC show equivalent result between both fuel gasoline and LPG, where optimum condition is ranging from 4.000 rpm until 5.000 rpm.
