Study On Power Increase Of High Altitude 16V280ZJA Diesel Engine

The density and mass flowrate of intake air decrease with the increase in altitude, which will cause deteriorated combustion and high exhaust temperature, thus the engine power and torque will decrease, and fuel consumption increase. For the purpose of the locomotive application in Qinghai-Tibet railway, to develop the new diesel engine suitable for high altitude is necessary. Qi Shuyan locomotive and rolling stock works, CSR, has developed a new diesel engine for high altitude based on their 16V280ZJA diesel engine having elevated high altitude power.This dissertation simulates the working process using AVL’BOOST software, describes useful measures for enlarging the engine high altitude power, and gives the design and development process.The simulated results were compared with the experimental ones on lab engine bench and from high altitude field locomotive operation. This showed a agreement between them, validated the feasibility of the measures for improving high altitude power, and lay a solid foundation for future performance optimization.
