Recently, china-Laos railway opened to traffic in this road of friendship, chongqing ABB Jiangjin Turbocharger System Co., LTD. research and development and production of turbocharger, CRRC Qishuyan company newly built six HXN5B high-power shunting diesel locomotive operation, for the China-Laos railway along the Kunming Ningxia Erh Wild elephant Valley Mohan and other 6 large freight yard services, to ensure the power and efficiency of locomotive operation, help it smoothly perform the duty of shunting in frequent start and braking.
The principle of turbocharging technology is to use the high-temperature gas discharged from the combustion cylinder to drive the impeller of the turbine cylinder to rotate, and then drive the impeller of the compressor end to rotate through the bearing of the middle shell, so as to press the fresh air into the cylinder, so as to ensure the optimal ratio of burning air and fuel 14.7 As of November 2020, turbochargers can increase engine thermal efficiency by 10% to 40%, but with the continuous innovation of existing turbocharger technology, turbochargers may be able to boost engine thermal efficiency by 45% or more.
