Turbocharger Market Size Doubled in 2018

At the 2013 China Automotive Industry Development (TEDA) International Forum, Honeywell, the world's leading automotive turbocharger manufacturer, made predictions on the sales volume of turbochargers in China. It is predicted that the market size will double from this year’s 5 million units. 10 million units in 2018.

According to Honeywell's estimation, the current turbocharger market share in China is about 22%. David Paja, President and General Manager of Honeywell Transportation Systems China, said, “We are clearly aware that the entire market is paying increasing attention to engine efficiency and emission reduction. Turbocharging technology can achieve both emission reduction and fuel improvement. The dual goals of economy, without sacrificing engine performance and driving pleasure, are increasingly favored by Chinese automakers and motorists."

In the Chinese market, turbocharger technology has a great advantage in diesel vehicles, according to Craig Balis, vice president of global engineering for Honeywell Turbocharged Technology, using Honeywell's VNT (Variable Section Turbocharger) technology. The 2.0L displacement Great Wall H6 diesel engine has 65% higher engine torque and 15% output power than the gasoline version, giving the driver more driving pleasure. The diesel version also has better fuel economy than the gasoline version. Therefore, turbochargers will be used in large quantities in China in the future for SUVs and light commercial vehicles manufactured in China.

Jin Chenhai, general manager of Honeywell's Turbocharged Technology Division in China, also stated that Honeywell is very optimistic about the potential of the Chinese market and will focus on promoting the latest diesel engine and gasoline engine technology while positioning itself in the mid-market development of “Oriental Service”. "Eastern" turbocharger products, and promote the popularity of turbocharger technology in the passenger vehicle field.

The popularity of turbocharging technology will be beneficial to the further improvement of the engine efficiency of the Chinese auto industry, and it will also be conducive to energy conservation, emission reduction and environmental protection.

G Shaped Finned Tube

The inlaid spiral finned tube is to pre-process the spiral groove of a certain width and depth on the steel pipe, and then inlay the steel strip on the steel pipe on the lathe. During the winding process, due to a certain pre-tightening force, the finned tube steel strip will be tightly clamped in the spiral groove, thus ensuring a certain contact area between the steel strip and the steel tube. In order to prevent the steel strip from springing back and falling off, both ends of the steel strip should be welded to the steel pipe.

In order to facilitate inlaying, there should be a certain side clearance between the steel strip and the spiral groove. If the side clearance is too small and interference is formed, it will be difficult for the mosaic process to proceed smoothly. In addition, the wound steel strip always has a certain springback, as a result, the steel strip and the bottom surface of the spiral groove cannot be well joined. Inlaid fins can be carried out on general-purpose equipment, and the cost is not high, but the process is complicated and the production efficiency is low.
