In 1690, French doctor Ddni Papin invented

steamed piston engine.

In 1776,Britisher Walt improved steamer and invented condenser with water and steam separated. thus steamer age bagan.

In1876, Nicolaus A otto developed a kind of four-stroke cycling internal-combustion engine, heat efficiency was increased to 14%, and weight was reduced almost 70%, ended the steamer age, and established the new techynology of the world internal-combustion engine.

In 1897, German engineer Rudoif Dieseed invented diesel engine, and heat efficiency improve almost doubled.

In1923, Eugene Houdry invented catalutic cracking process, and this largely improved the output of the fuel and anti-explosion.

In 1952, AJ. Haagen Smit took the lead in putting forward motorcycle environment protcetion theory.

In 80s, 90s multi-tire valve technology, electricity spray technoloty, variable valve area and variable timing technotogy is gensralty applted.

Today,internal-combustion engine and motorcycle brings the world modern material civilization.its invention has not reached the peak,and it need to be improved in power,economy and discharge control.The appearance of new material cause the internal-combustion engine to further reduce the weight.lower the cost and heat loss.New types of engine combine the advantage of petrol engine and diesel engine.The internal-combustion engine that uses many fuels will have good appliance outlook.These provide new requests and challenge for the workers of internal-combustion engines.

We create together tomorrow of the internal-combustion engines.

We expect that Jinlang engine is not only the commodity,but also artwork.Let the people who possess Jinlang possess a kind of aesthetic enjoyment and create the ROLEX in the world of engine.

We expect that our technology innovate endlessly,surpass self,challenge self,and provide the human with the best motion experience.

The advantage of Jinlang is to integrate the world resources,just for one goal-to make the world——class engine by the first-class artisan.
