Zichai ZC330ZLC/S series dual-fuel engine takes the ZC330 series diesel engine as the parent engine, fully absorbs domestic and foreign advanced technology and design ideas, and is designed and developed on the basis of maintaining its good power, economy, reliability and other advantages. Medium-speed and high-power ZC330ZLC/S series LNG/diesel intrinsic multi-point injection dual-fuel engine. The ZC330ZLC/S series dual-fuel engine adopts an essential design, and the natural gas supply system is in the engine room under any circumstances; it adopts domestic quasi-internally mixed gas electronically controlled multi-point injection technology. The engine can switch working status according to actual working conditions, and can work on LNG dual fuel or diesel alone. It realizes the ratio of gas and diesel injection through the electronic control unit, so that the engine is always running in the best condition and saves diesel without affecting the power output. The fuel replacement rate at part load points can reach 85%, and the fuel replacement rate at full load is not less than 70%. The ZC330ZLC/S series dual-fuel engines have the advantages of advanced design, reasonable structure, reliable performance, high degree of automation, easy maintenance, low fuel consumption, and low emissions. They are mainly used for main engines or auxiliary engines of LNG carriers and bulk carriers. It can meet the requirements of aircraft side control, remote control and UAV cabin.
Introduction to Zichai dual fuel control system
More economical: Liquefied natural gas (LNG) gas supply system: mainly composed of gas inlet pipe assembly, corrugated double-wall hose assembly, and injection valve assembly, used to provide the engine with the required flow and pressure of gas fuel.
More advanced: Gas control system: It adopts the world's representative Heinzmann controller MVC01-24 and the gas injection valve Megasol 250 with double-wall structure. The gas control and related alarm control meet the ship regulations, which greatly improves the timeliness of the gas system. The engine is self-protected, which is the first of its kind in China. The schematic diagram of the control system is as follows:
Smarter:
Electronic control speed control system: It adopts the combination of speed control actuator RE2800 and controller. Heinzmann electronic controller MVC 01-24 outputs a 0~1A speed control signal to the built-in electromagnetic coil of RE2800. The electromagnetic coil generates electromagnetic force. To control the output fuel supply of RE2800, it effectively controls the diesel supply of the engine and provides technical support for the realization of a high replacement rate of engine gas. Compared with traditional mechanical hydraulic speed regulators, the RE2800 electronic hydraulic speed regulator has large torque and high reliability. It integrates the advantages of Heinzmann electronic controllers, and its speed regulation performance and control accuracy are at a relatively high level. Speed regulators are now widely used in MAN's 2131 models, and the technology is mature and reliable.
More reliable:
Gas intake system: The gas injection valve adopts a double-wall tube structure. The gas inlet main pipe and branch pipe adopt double-wall pipe structure, which is small in size and has high safety factor.
