Effect of Different Fuels on Fuel Consumption of Hybrid Vehicles

The use of energy resources is increasing day by day. Accordingly, the search for different energy sources continues by researchers all over the world. In particular, the search for alternative energy sources to fossil fuels has increased in recent years. As the production of hybrid vehicles increases, the availability of fuels that can be used in hybrid vehicles is being investigated. For the hybrid vehicles, which are the subject of our study, the effects of the availability of natural gas on internal combustion engines were examined. In the study, numerical analyses were carried out by using AVL Cruise program. In the analyses, the properties of natural gas were compared with the properties of gasoline. The hybrid vehicle subject to the study was selected from the library of the AVL program. A four-cylinder, four-stroke, 1.5 L spark ignition internal combustion engine was selected. An electric motor with 10 kW power, nominal voltage 144 V and maximum current 150 A was applied. According to results of the analyses, it has been observed that gasoline consumes 12.5% less fuel as mass than natural gas at the same driving distance.
