Series 26/32 of the natural gas engine is developed by Jichai to meet the demand of national energy conservation and emission reduction projects.

Compressor D series can be used for gas collecting, gas production and gas injection (gas storage), oil and gas treatment and processing, gas lifting, light hydrocarbon recovery, natural gas liquefaction, refining, gas drilling, and pipeline pressure testing.

Series 2000 diesel engines have been greatly improved in terms of improving the reliability, economy, power performance

Series 3000 diesel dynamic, economic indicators have been greatly improved, the main performance indicators have reached or close to today's international advanced level.

Precise control (INTERNATIONAL: 2.1-2.3, Aid: 2.05) to achieve rarefied combustion;

High efficiency (international: 42-45%; current test thermal efficiency: 44%), safety (explosion-proof devices, double-wall gas pipe, and oil mist detector are installed in each system);

High supercharging, strong MILLER, low emission;

Series 3000 marine engine is a kind of diesel engine with the character high supercharging, high power, low fuel consumption, high reliability, and long service life.

Series 4000 long-stroke diesel engines​ are designed according to the domestic and foreign internal combustion engine industry dynamics, aiming at designing for the mechanical equipment and power unit with large load variation.
