The Weichai machine is equipped with the 6210 diesel-natural gas dual-fuel marine engine (product warehouse supply) successfully delivered to the shipyard and successfully passed the inspection of China Classification Society (location contact). The dredging and self-unloading barge constructed by the ship provides the main power. The rated power of the engine is 883 kW and the displacement is 60.27 liters. It is the first successful application of the first self-developed electronically controlled multi-point injection system in the ship, breaking the domestic market monopolized by foreign technology and opening the inland navigation. A new era of dual fuel power for ships.
     As the country pays more and more attention to clean energy, natural gas energy single-fuel and dual-fuel engines are favored in the inland shipping industry. Among them, natural gas injection systems are the key to affect the performance of single/dual fuel engines. Currently, there are mainly single-point premixing. Injection system and electronically controlled multi-point injection system. Due to the large scavenging angle of the marine engine, the single-point premixing scheme will cause problems such as large gas consumption, high exhaust temperature, tempering and shooting, and a low safety factor. Domestic applications of multi-point injection systems are all dependent on imports and are expensive.
     In April this year, the new generation of domestically produced electronically controlled multi-point injection system dual-fuel 6210 engine jointly built by Weichai and Lichuang successfully operated in the Xiangjiang River Basin. Lichuang Technology multi-point injection system includes electronic control unit (ECU), ship monitoring (product library purchase supply) instrument, gas injection valve (product library purchase supply), wire harness, sensor (product library purchase supply) and other powertrains . The ECU is uniformly controlled, and the pure diesel mode and the dual fuel mode can realize one-button switching. The self-powered cloud platform system can realize real-time monitoring of all information of the ship. The cylinders of the engine work evenly, and the discharge temperature is lower. Compared with the diesel engine (purchasing supply), the power is not reduced. Not only is it safe and fuel efficient, but emissions and temperature are significantly reduced.
     In the field of ship and power generation, the system not only successfully assembled the Weichai single/double fuel ship, but also matched Weichai WP13, Weichai Boduan 6M33, oil Jichai (ship hangar position) 6190/12V190, victory power 12V190, Zhongche Yuchai 9210, China National Heavy Duty Truck Steyr, Ruirisheng YCK13, Xinshengan Power, Germany Wagner Power, Yituo Dongfanghong series engines.
     Founded in 2010, Weifang Lichuang Electronic Technology Co., Ltd. is the only state-level high-tech enterprise, dual-soft certification enterprise, national strong-based engineering catalogue enterprise, inland navigation and fishing boat that independently researches and develops gas engine electronically controlled multi-point injection system. Ship type shipyard trading) Double fuel reform industry standards and national standards development companies. The company focuses on the research and development, production and sales of advanced engine fuel and emission electronic control frontier technology products. Through continuous technological innovation, the product performance and indicators have reached the international advanced level in the same period. Many technologies have filled the domestic gap and have domestic fields. All invention patents and international patents have broken the monopoly of foreign technology and brand of gas engine multi-point injection system, greatly reduced the cost, responded to the national energy conservation and emission reduction call, met the current and future engine emission indicators, and improved the performance and use of the engine. life.
