Design, Development and Evaluation of CNG Fuel System for Using in Diesel Engine of Tractor

Today using fossil fuels such as gasoline and petrol in order to apply in gasoline and petrol engines have faced with serious challenges such as high costs of servicing, fixing, storing, and lacking of safety. Therefore finding suitable substances can help to solve these problems in industry and energy sections. In this essay, system of compressed natural gas fueling is used in the tractor diesel. So that, the physical structure of it is based on lowest changes in general mechanism of engine and lowest used amount of electronic and mechanical equipment and parts. The results show that the designed system is able to answer the engine needs and to reduce pollution rates.
