[Xiagong Chusheng Original] Weichai Power added a multi-state switch function to the BOSCH electronic control system on its WP10 and WP12 series engines. This function can limit the engine speed and make it run according to the operating conditions of the vehicle. In the specified torque and speed area. The principle of this function is to use the on-board computer (ECU) to detect different voltage values ​​and make the engine run in different states. By calibrating the torque and speed regions corresponding to each state, the engine can be operated within a limited torque and speed range depending on the operating conditions. The following figure shows the division of the power stalls of Weichai WP10 and WP12 series engines . Chongqing Huanyu Automobile Sales Company , https://www.huanyuauto.com After vehicle test verification, when the vehicle is unloaded or half loaded, by limiting the output torque and speed of the engine, the driving habits of the driver can be effectively improved and the fuel consumption of the vehicle can be reduced. At present foreign trucks and construction vehicles have used similar technologies.
This function is a special feature added to Bosch's electronic control system. Only vehicles that use the Bosch common-rail system have this function. Other models using Bosch's electronically controlled common-rail system also have this function. Consult the corresponding engine manufacturers for specific parameter performance.
