In 2014, the production and sales of Weichai gas engines were booming and occupied a large market share. However, the highly profitable subsystems of the engine, electronically controlled ECUs, are completely dependent on foreign imports. For this reason, the Electronic Control Technology Department of Weichai Engine Technology Research Institute took a year to successfully develop an autonomous gas ECU. At present, this smart product is in the customer verification phase. After batch production, it will break the long-term foreign monopoly of Weichai Gas ECU and install a “Chinese core†for gas vehicles.
On January 26, 2015, in Changchun, China, a heavy truck equipped with a Weichai gas engine was cold-started successfully at a temperature of minus 26 degrees Celsius. According to feedback from testers, the heavy-duty vehicles that participated in the test have been equipped with Weichai's independently developed gas ECUs on their engines. After nearly half a month of high-Cold challenge, the engine performance indicators met the design requirements, and some data were even better than fitting. Foreign gas ECU engine.
In 2015, Weichai will increase its research and development efforts, complete the development and verification of autonomous ECUs according to the process, and at the same time, make technical preparations for autonomous system integration, and gradually realize the replacement of autonomous ECUs.
A fiber laser is a laser where the active medium being used is an optical fiber that has been doped in rare elements; typically, erbium, ytterbium, neodymium, thulium, praseodymium, holmium or dysprosium. While you don`t need to worry too much about which rare-earth elements have been used, the main thing to note is that it is fiber that is being used at the centre of this Laser Machine. This is different to the two other main types of laser, which are gas lasers (typically uses helium-neon or carbon dioxide) and crystal lasers. Fiber lasers are the newest type of laser to hit the market, with many arguing that it is the more beneficial of the three types.
