Currently, thermal efficiency for truck engines averages around 46 percent. In addition to its common-rail system with injection pressure of 2,500 bar, Bosch also contributed its full technical know-how in fuel injection systems. Particularly when it comes to commercial vehicles, and above all when heavy loads have to be transported over long distances, the diesel engine will remain the preferred choice for the foreseeable future. For this reason, Bosch and Weichai aim to steadily refine this technology with an eye to protecting the climate and environment.

Bosch and Weichai, China’s largest manufacturer of engines for commercial vehicles, have enjoyed many years of partnership. Their strategic alliance began back in 2003. Over the 17 years since, both companies have pooled their strengths and expertise in multiple endeavors, one of which was supplying the Chinese market with powerful, energy-efficient, and eco-friendly diesel engines. Furthermore, Bosch and Weichai collaborate in several other areas, including the mobile fuel cell and driver assistance systems. They are united by a common objective: making commercial vehicles even cleaner, safer, and more intelligent. Bosch and Weichai’s close partnership also extends beyond vehicle technology – to Industry 4.0, for example, and in turn, the connectivity and digitalization of factories.
