    INTRODUCTION INTRODUCTION

    Since the middle of 2005, the government of Since the middle of 2005, the government of Indonesia has policy and regulation to develop Indonesia has policy and regulation to develop the use of alternative fuel such as coal, natural the use of alternative fuel such as coal, natural gas, green fuel to reduce Indonesiagas, green fuel to reduce Indonesias demand of s demand of refined petroleum product. As we knew that refined petroleum product. As we knew that since 2002, this country was a net importer of since 2002, this country was a net importer of petroleum fuel products.petroleum fuel products. Natural Gas as commercial fuel for motor Natural Gas as commercial fuel for motor

    NATURAL GAS AS FUEL FOR VEHICLESNATURAL GAS AS FUEL FOR VEHICLES

    Natural gas as fuel for vehicles its usually called Natural gas as fuel for vehicles its usually called CNG is the natural gas that has been purified and CNG is the natural gas that has been purified and compressed at the elevated pressure up to 200 compressed at the elevated pressure up to 200 bars (2900 Psi). bars (2900 Psi).

    Generally, it contains two major components i.e. Generally, it contains two major components i.e. methane (CHmethane (CH44) and ethane (C) and ethane (C22HH88). ).

    To provide guarantee that the quality of natural To provide guarantee that the quality of natural gas for CNG motor vehicles is safely for gas for CNG motor vehicles is safely for infrastructure and installation equipment at the infrastructure and installation equipment at the filling station and motor vehicles, it needed the filling station and motor vehicles, it needed the standard or specification of this fuel.standard or specification of this fuel.
