On June 8, 2013, a large-scale series of “ Hunan Fuel-efficient Weichai Line†Weichai Power National Fuel Experience Camp was opened in Yantai. Local dealers, heavy truck users, and media reporters totaled more than 100 people and witnessed the Weichai engine together. Excellent fuel economy.
The Weichai Power Fuel Economy Experience Camp was jointly organized by Weichai Power and Yantai Jiyun Yunye Co., Ltd., and senior leaders of Weichai Power and Jida Corporation attended the event. There are two vehicles participating in the fuel-saving test, namely the Weichai WP12 four-valve common-rail low-speed engine truck and the truck equipped with another brand of engine. In accordance with the rules of the activities, both vehicles are marked with 35 tons, and they will drive from the entrance of Zhihai Island of Shenhai Expressway to the high-speed exit of Yanjiazhuang Town and return from the original road. The entire journey is about 90 kilometers. Each vehicle will maintain a speed of about 70 kilometers per hour, and change the driver during the test half-way to reduce the impact on fuel consumption due to the driver's driving habits and other reasons.
Before starting, the staff carefully examined the oil dial and tested the equipment. After everything was ready, two trucks started to leave. After about two hours of fierce competition, two trucks returned to the starting site. The two vehicle supervisors carefully checked and recorded the data and announced to everyone the fuel consumption of each vehicle. The customers present were also invited to check the data. The test results show that the Weichai engine consumes 25.638 liters of fuel, which is 2.819 liters less than another brand's engine. The fuel-efficient rate is 10.9%, and the fuel consumption per 100 kilometers is 25.08 yuan. Such excellent fuel consumption performance made the audience screamed and praised the remarkable fuel-saving performance of the Weichai engine.
Recently, the prices of domestic refined oil have been fluctuating. After experiencing three consecutive falls, the oil prices of most cities have returned to the “7-year eraâ€. For heavy truck users, the increase in oil prices has increased the cost pressure. The implementation of weight-based toll collection and over-limit measures has had a great impact on the operating model. Therefore, users are most concerned about the problem of reducing truck use costs through fuel saving. During the fuel-efficient experience camp held in Yantai at Weichai Power, the heavy truck carrying the Weichai WP12 four-valve common-rail low-speed engine was able to win an ordinary heavy truck. The key lies in "D-speed power" and "optimal powertrain matching. Application of technology.
"D Speed ​​Power" is a truck power specially developed by Weichai Group using domestic and foreign technology and R&D support platforms. Based on the relationship between engine rated speed, maximum output torque and engine fuel consumption, Weichai has reduced the rated engine speed of the standard version to 1900 rpm, forming the best match between the low-speed engine and the torque converter, thus avoiding the high engine speed and high fuel consumption area. , Broaden the low fuel consumption area, reduce the number of user shifts, and effectively improve fuel economy. At the same time, Weichai matched the multi-gear transmission and the small-speed single-stage rear axle on the basis of D-speed fuel-efficient power to form a professional and efficient "powertrain optimization and matching technology", which improved the fuel economy of the engine. And enhance reliability and power performance. In addition, Weichai also upgraded the configuration of the engine in various ways. The application of electromagnetic constant-temperature fans, fuel oil and cold water, and WP multi-power fuel-saving switches effectively reduced the fuel consumption of the engine. The optimization and upgrading of these technologies and equipment enables Weichai to provide users with more efficient and superior fuel-efficient solutions.
It is reported that in addition to the WP12 series engines that were unveiled at this experience event, Weichai's fuel-efficient power products also include WP10N, WP10NE32 and many other series. In addition, Weichai also gave detailed performance explanations for its natural gas engines.
"In the field of truck engines, Weichai Power has upgraded the key technologies and innovated key technologies to further realize the high-efficiency and energy-saving of engines, which has enabled Weichai Power to be at the forefront of the world's internal combustion engine industry." Weichai's senior leaders expressed this at the event. .
