The reporter recently learned from Weichai Power Sales Company that due to the self-developed LanQingGuo three-engined high-pressure common-rail engine, which has powerful intelligent control functions, Weichai Power has built on this basis the United Nations internal and external partners and developed more WPs. The power-saving switch enables the engine's power to be adjusted and achieves the efficiency of a single engine to several engines. After the Blue-Qingguo three-electricity high-pressure common-rail engine equipped with the WP multi-power fuel-saving switch was put on the market recently, the fuel-saving effect was remarkable, breaking the user's suspicion that the country's three engines were less expensive than the two engines. At the same time, in view of the fact that the diesel water content of some gas stations is exceeding the standard, Weichai Power Co., Ltd., together with European suppliers of oil-water separators, jointly developed the “water removal filter,†which can remove more than 95% of the moisture content of diesel fuel and reduce the overall failure rate. The relevant person in charge of Weichai told reporters that through the joint development of these two developments and the WEVB (engine braking technology) that had been previously applied, the blue-engined three-way high-pressure common-rail engine has truly reduced exhaust gas pollution. It also achieves energy-saving effect, which greatly saves the cost for the user.
At present, the mainstream engine factories in China have selected the high-pressure common rail technology when developing the three diesel engine products. Therefore, the diesel engine products have achieved a complete transition from mechanization to intelligent electronic control. According to the technical personnel of the Weichai development department, the WP multi-power fuel-saving switch is one of the applications of diesel engine intelligent technology and can meet the power requirements of vehicles under no-load, medium-load, heavy-load or different road conditions. At any time, the driver can select the best engine power and reduce the extra power consumption by just turning the fuel-saving switch. The overall fuel consumption of the vehicle can save an average of 2.6 liters/hundred kilometers. Taking a heavy truck equipped with a WP10.336 engine as an example, the driver selects three different power output modes of heavy load, medium load, and no-load according to different road conditions and different carrying capacity to achieve the purpose of fuel economy.
It is reported that Weichai Power has developed a 2, 3, and 4-speed WP multi-power fuel-saving switch using the powerful electric control function of Lanqing Guosan and obtained 15 years of national technical patents and registered trademarks. The product adopts BOSCH end piece package and imported TEFLOW super wire to achieve digital intelligent power conversion of ECU. The product also has a failure protection function. The ECU can automatically detect the WP multi-power fuel-saving switch status. If the switch fails, the engine will automatically resume the heavy load. At the same time, the ECU will display the fault code to remind the driver to replace.
At present, the high water content of diesel fuel is a big headache for truck drivers. High-water-contained diesel fuel is extremely harmful to both the National 2 and National 3 engines. For this purpose, Weichai and the European professional company jointly developed the "water removal filter", the water removal rate of up to 95%, to ensure the safety of diesel engines.
It is understood that the "water removal filter" has four advantages: efficient oil-water separation function, allowing users to rest assured that the use of light diesel oil with high domestic water content; easy to use, rest assured that the filter installed in the obvious position of the vehicle frame, with Large-capacity transparent water cup for driver's observation of water level and water discharge; reliable performance, good low temperature resistance; double insurance - with hand pressure pump, convenient for the driver to exhaust and pump oil.
The person in charge of Weichai Power Sales Co., Ltd. introduced to reporters that Weichai promised that vehicles equipped with the blue engine of the company should be installed in accordance with the above requirements after the “remove water and filter†and maintained according to the maintenance specifications of Weichai Power ( Routine maintenance replaces the coarse filter element of diesel oil. When the fine filter element is replaced, the “water removal filter†filter element must be replaced at the same time. If there is a fuel injector or oil pump failure within the three-pack period of the engine, Weichai Power will carry out three packages for free.
According to the comprehensive calculations made by the Weichai Power Technology Development Department and users, the WP multi-power fuel-saving switch, “water removal filterâ€, and the Lanqing Guosan diesel engine of WEVB technology have the best comprehensive performance, saving 2.6 liters of combined fuel consumption. / 100 kilometers; the speed of the blue engine has been put on the market, the country's third failure rate is 63% lower than that of the country's second engine; WEVB has improved the braking efficiency by 55%; and the user's operating cost can save 25,000 yuan a year.
