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. The R&D multi-point injection system includes the entire powertrain such as an electronic control unit (ECU), a ship monitor, a gas injection valve, a wire harness, and a sensor. 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 do work evenly, the discharge temperature is lower, and the power of the diesel engine is not reduced. Not only is it safe and fuel efficient, but emissions and temperature are significantly reduced.
In the field of shipbuilding and power generation, the system not only successfully assembled Weichai single/double fuel ship, but also matched Weichai WP13, Weichai Boduan 6M33, oil Jichai 6190/12V190, Shengli Power 12V190, Zhongche Yuchai 9210, China National Heavy Duty Truck Steyr, Rui Risheng YCK13, Xinsheng An Power, Germany Wagner Power, Yituo Donghong Series and other 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 with independent research and development of gas engine electronically controlled multi-point injection system. The establishment of fuel reform industry standards and national standards.
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. 
It is reported that the 6210 diesel-natural gas dual-fuel marine engine of Weichai Machinery Co., Ltd. is successfully delivered to the shipyard and successfully passed the inspection of China Classification Society. It will provide the dredging and self-unloading barge that is being built. 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.
