Businesses in the Weifang Hi-Tech Industrial Development Zone are working to capture the spirit of China's innovation-driven development strategy.

Weifang Litro Electrical Technology Company, an engine systems developer and manufacturer in the local Blue Wisdom Valley, introduced a new injection technology, known as multi-point sequential injection control, in early 2016.

"In previous years, singlepoint, pre-mixed systems supplied by foreign developers including Woodward in the United States and Bosch in Germany were widely used by major engine producers in China. That technology has explosive risks," said Wang Xiuqiang, deputy general manager of Litro.

"Developing new injection technology to improve the overall performance of engines has long been a common goal of local engine businesses," Wang said.

The newly developed technology improves natural gas engines' overall performance and reduces gas consumption significantly, according to the company.

"The patent helped us generate more than 20 million yuan ($2.9 million) in extra income in 2016. We expect Litro's overall sales revenue to reach 50 million yuan in 2017 and 200 million yuan in 2018," Wang said.

Weifang Conqueren Bioscience & Technology Co, a fish feed developer, is another leading innovator in the development zone. Clients' feedback shows the company's fish feed can better support growth of young fish than their imported counterparts.
