What CSIC does

Henan Diesel Engine Heavy Industry Co., Ltd. (河南柴油机重工有限责任公司 / 河柴重工 / HND) is a Chinese state-owned manufacturer of high-speed and medium-speed diesel and gas engines for internal combustion applications, founded in May 1958 as one of the 156 key projects of China's First Five-Year Plan and the first high-speed diesel engine factory in New China. The company is a wholly-owned subsidiary of China Diesel Engine Co., Ltd. (中船柴油机有限公司) under China State Shipbuilding Corporation (CSSC), making it the sole domestic supplier of high-speed high-power internal combustion engines under China's naval and shipbuilding conglomerate. Its product portfolio spans six core engine series (234, 316, 604, 620, 622/622CR, plus MAN-licensed medium-speed 16/24 and 21/31) and gas engine series (TBG236, TBG620), covering power outputs from 110kW to 4000kW for naval vessels, commercial shipping, nuclear power emergency systems, mining dump trucks, gas power generation, and offshore platforms.

The company's technology platform has evolved from licensed German engineering (DEUTZ-MWM 234/604/620 in 1985 and 1999; MAN 16/24 and 21/31 in 1996 and 2007) to fully independent proprietary IP, with the CHD622 series representing China's first domestically-developed high-speed high-power diesel engine above 3000kW. Core proprietary technologies include high-pressure common rail fuel systems (in-house since 2017), sequential turbocharging control, multi-point injection, and dual-fuel combustion systems. The company has positioned itself at the frontier of green-fuel propulsion with the CHG234V8MMPI pure methanol engine (China's first CCS type-approved marine methanol engine, 44% thermal efficiency), the CHG620V12MMPI methanol engine for inland river vessels, and the CHG234V8MPI ammonia-fuel generator set powering the world's first ammonia-fueled marine demonstration vessel 'Yunhui'.

The business model combines direct hardware sales (diesel engines, gas engines, generator sets, and complete propulsion/power systems) with after-sales service and maintenance contracts. Distribution is exclusively direct enterprise field sales, organized into specialized divisions for military products, shipbuilding and applications, service support, new energy, and intelligent control, with no third-party resellers. Pricing is bespoke and project-based, with multi-year contract cadences typical for defense, nuclear, and large commercial marine engagements. Customers include the Chinese Navy, CNNC and affiliated nuclear operators, Hainan Marine and Fisheries Supervision, Zhunneng Group (mining), Guangdong Province and China Shipbuilding Group (LNG vessels), Chongqing Yangtze Gold Cruise, and Zhanjiang Bay Laboratory (offshore aquaculture), with exports reaching Pakistan, Indonesia, Philippines, and Australia.
