| Abstract:According to the market demand, taking TBD620V12 diesel engine as the prototype, the optimal design with 1 200 r/min as the rated speed was carried out. Based on AVL-BOOST, simulation was carried out on the diesel engine to study its working process. At the same time, the intake and exhaust system, lubrication system and cooling system of the diesel engine were calculated and evaluated, and applicable parts were selected. Test results show that the exhaust temperature, fuel consumption rate, oil pressure and other parameters of the prototype meet the design requirements. |
