ABSTRAK
Motor bensin sekarang ini sudah menjadi kebutuhan pokok bagi masyarakat di Indonesia dan dunia. Hal ini dibuktikan dengan banyaknya penggunaan motor bensin pada mesin-mesin penggerak seperti mobil. Hal ini menyebabkan konsumsi bahan bakar semakin meningkat setiap tahunnya. Karena semakin meningkatnya konsumsi energi, maka sumber energi pun semakin menipis dan menyebabkan krisis energi di Indonesia dan dunia. Hal inilah yang menjadi alasan utama para peneliti dalam mengembangkan teknologi-teknologi yang bisa menghemat penggunaan bahan bakar di dalam kendaraan. Salah satu cara penghematan penggunaan energi di dalam kendaraan secara external proses adalah dengan menggunakan Electronics Gas Booster (EGB). Electronics Gas Booster berfungsi untuk melemahkan ikatan H dan C yang terkandung di dalam bahan bakar bensin sehingga memudahkan oksigen (O2) untuk bercampur dengan H dan C didalam pembakaran. Hal ini menyebabkan pembakaran bisa lebih sempurna. Dengan menguji kendaraan yang dilengkapi alat bantu Electronics Gas Booster pada kendaraan, kita bisa membandingkan kinerja motor bensin yang menggunakan Electronics Gas Booster dan yang tidak menggunakan Electronics Gas Booster. Dari hasil pengujian terlihat bahwa motor bensin yang memakai Electronics Gas Booster bisa menghemat pemakaian bahan bakar, menaikkan daya poros dan efisiensi mesin juga menjadi lebih tinggi.
ABSTRACT Petrol engine this time have become fundamental requirement for society in Indonesia and the world. This matter is proved with many petrol engine use at activator machine like car. This matter cause fuel consumption progressively mount every year. Because that progressively, the increasing of consumption energy hence source of energy even also progressively attenuate and cause crisis energy in Indonesia and world. This matter become especial reason all researcher in developing technologys which can economize fuel use in vehicle. One of way of use energy thrift in vehicle externally process is by using Electronics Gas Booster ( EGB). The function of Electronics Gas Booster is to weaken tying H and C which consisted in gasoline fuel so that facilitate oxygen (O2) to mixed with H and C in combustion. This matter cause combustion can more perfect. With testing vehicle which that equiped by assistive appliance of Electronics Gas Booster at vehicle, we can compare petrol engine performance using Electronics Gas Booster and which not use Electronics Gas Booster. From examination result seen that petrol engine which hence Electronics Gas Booster can economize fuel usage, boosting up efficiency of engine and axis energy also become higher.
