Record: Liugong first won the national authorization of the engine invention patent

Liugong recently authorized the national patent office to win the invention patent of "control of engine's power curve according to lifting and overcoming external load capacity". This is the first technical invention patent for Liugong's entry into the engine field, and it is also a symbolic technical result of cooperation with the world-class enterprises Cummins.

In this patent, and then start the engine power point in a certain range as the speed increases from the amount, in reaching a peak then decreased with increasing speed, the power curve to form a "Hump", this is a sign of the patent characteristics. The engine with this power characteristic can automatically output more torque when the vehicle meets large working resistance, so as to overcome the resistance of the shovel and lift the working efficiency of the vehicle. The design of the "Hump" power curve, the project team has a large collection of load loader in different working operation optimization of the economic spectrum, fuel consumption of the engine itself, the economy in the matching efficiency interval in torque converter, to ensure that the engine in maximum power, the bucket lowest fuel consumption. The power characteristic of the traditional engine is not fully integrated with the working characteristics of the whole vehicle in the design, and it can not be fully adapted to the job requirements of the loader.

Record: Liugong first won the national authorization of the engine invention patent

This hump power invention patent has been successfully applied to a series of engine products produced by Cummins power limited company in Guangxi, and has been successfully applied in Liugong H series loaders. After the product is listed, the customers generally reflect the more powerful, fluent and lower fuel consumption of the same product in the industry. At present, the engine supporting company loader products, at the same time, also facing all the national loading mechanism manufacturers.

The technical characteristics of the invention patent were put forward by the chief scientist of Liugong in 2012. He led the company engineers and technicians of Cummins set up cooperation team, the fusion of their technical advantages, sincere cooperation, to declare the patent in March 2013, in December 2015 authorized, once again reflects the Liugong "cooperation to create value" of cultural connotation. This patent technology is specially developed for the loader, and it has also explored a new road for the technology research and development of other engineering machinery products.

The birth of a new patent, means Liugong once again win glory for the country, made a positive contribution to the progress of human society.
