The Qinghai-Tibet Railway is the highest and longest plateau railway in the world, and is affectionately known as the "Road to Heaven".
Travelling on the "Heavenly Road", the oxygen content at the highest altitude is only about 50% of that of the plain, and due to the complex geological environment and harsh climatic conditions, internal combustion locomotives also suffer from "plateau reactions" similar to those of human beings, such as locomotive emissions, operating power, engine exhaust temperature and fuel consumption deteriorating significantly compared to plain applications. and the high engine temperature also leads to high engine and supercharger failure rates.
In order to improve the locomotive's adaptability to the plateau in the extremely low oxygen content environment, CNR Dalian cooperated with ABB and used the TPR61-F supercharger to carry out targeted optimisation of the locomotive's plateau operation, significantly increasing the cylinder intake of the locomotive's diesel engine and improving the diesel engine's exhaust temperature and fuel consumption in the plateau operation environment, as well as solving the problem of black smoke from the locomotive and improving the engine's reliability and The engine's reliability and economy have been improved.
The TPR series turbocharger is a new generation of turbocharger products specially designed by ABB for long-distance heavy-duty mainline internal combustion locomotives and shunting internal combustion locomotives, with high pressure ratio, high efficiency and long service intervals.
This time, ABB specifically for HXN3 internal combustion locomotive plateau operation to provide the TPR61-F supercharger maximum boost pressure ratio of up to 5.8, supercharger total efficiency of 65%, ultra-high pressure ratio and ultra-high efficiency to ensure that the locomotive in the plateau operating environment in the engine cylinder of the total air intake close to the plain use, making the engine combustion more fully, effectively solving the internal combustion locomotive "plateau disease".
