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.

Open source Securities released a research report on December 06, the first to best buy rating, is expected in 2021-23 revenue of 10.86/13.15/1.636 billion yuan, net profit of 2.15/2.88/387 million yuan, EPS of 1.07/1.44/1.93 yuan/share, PE was 23.3/17.4/13 times.

It has a design speed of 22 nautical miles per hour, a maximum load capacity of 198,000 tons, and can load 21,000 standard containers, reaching the largest level of container ships in the world compared with container ships built before. Cosco Shipping Cosmos has the advantages of advanced technology, excellent performance, energy conservation, environmental protection and high intelligence, which represents the highest level of shipbuilding technology in China.

Core industrial diesel turbochargers include Garrett Honeywell, BorgWarner, Cummins Turbo and MHI. Europe is the world's largest manufacturing region with a share of nearly 50 percent, followed by Asia Pacific and the Middle East and Africa with a share of about 35 percent and 15 percent, respectively.

First of all, the turbocharger is located in the engine intake and exhaust system, which increases the intake volume by compressing the air. At work, it uses the inertia impulse of the exhaust gas discharged from the engine to promote the turbine in the turbine chamber, thus driving the coaxial impeller, which then compresses the air to pressurize it into the cylinder.
