Zichai Power Co., Ltd. is subordinate to China Agricultural Development Group Co., Ltd., which is directly under the state owned assets supervision and Administration Commission. It was established in 1970 with nearly 1100 employees. It is a professional manufacturer of high-power medium and high-speed marine diesel engines in China. It consists of three subsidiaries: Zichai Machinery Co., Ltd., Qingdao Zichai Boyang Diesel Engine Co., Ltd. and Zibo Zichai New Energy Co., Ltd.
　　The company has a nationally recognized enterprise technology center, a post-doctoral scientific research workstation, and a key laboratory for marine engine performance research in Shandong Province. it has successively undertaken a series of projects such as the national "863" plan, the torch plan, the national key new product plan and the high-tech ship scientific research plan, and has passed the quality, environment, occupational health and safety management system certification. The trademark "Zichai and Picture" has been recognized as a well-known trademark in China.
　　The company's main business is research and development, manufacturing and sales of 150, 170, 180, 190, ZC200, 210, 250, ZC270, 300 and N330 series marine diesel engines. 150, 170, 210, 250, N330 series dual-fuel engines; Using biomass gas, coalbed methane, biogas, oil shale gas, blue carbon gas, etc. as raw materials, there are several series of gas-fired generator sets and coal mine spent air gas thermal countercurrent oxidation devices. Products are widely used in ocean shipping, inland shipping, passenger and cargo, transportation, fishing vessels, port tugboats, engineering ships, law enforcement ships, military auxiliary ships, marine generator sets, land generator sets, peak power stations and pump station units, etc. The leading products maintain a high market share in the domestic industry, and have been exported to more than 20 countries and regions, and have strong competitiveness in the international ship and gas engine markets.
　　In recent years, the company has independently designed and developed a series of diesel engine products with international advanced level, such as V170, ZC330, ZC270, ZC200, etc. Among them, V170 diesel engine technology is exported to foreign production, creating a precedent for my country's high-power engine technology output. Breaking through the key technology of low-power marine medium-speed natural gas/diesel dual-fuel engines, the transformation results have formed Z170, 210, 250, N330 and other series of marine natural gas/diesel dual-fuel engines, of which Z6170 diesel engine, 8300 biomass gas engine and 6210 dual-fuel engine are listed as national key new products, and L8250ZC-2 diesel engine has won the National Science and Technology Achievement Award.
