Customer First Helps Customers Solve Problems and Create More Value
On the road of independent innovation, Weichai will create more value for customers as the first element to incorporate the design concept. This year, we have successfully developed a number of patented technologies in fuel consumption reduction. The introduction of the WP multi-power fuel-saving switch allows Customers get more benefits. This fuel-saving switch is based on the powerful electronic control function of the Blue Engine Group III diesel engine, and has developed a WP multi-power fuel-saving switch with 2, 3, and 4 positions. The main function is to make the power of the diesel engine adjustable and realize the user to buy a diesel engine. To achieve the efficacy of several diesel engines. WP multi-power fuel-saving switch is one of the applications of diesel engine intelligent technology to meet the power requirements of vehicles under no-load, medium-load, heavy-load or different road conditions. Taking the heavy truck equipped with WP10.336 diesel 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 loading capacity. You can select the most simply by gently pushing the fuel-saving switch. The excellent diesel engine power reduces the extra power consumption, so that the overall fuel consumption of the vehicle can save an average of 2.6 liters/hundred kilometers. After the Lanqing Guo III electronically controlled high-pressure common-rail diesel engine equipped with the WP multi-power fuel-saving switch was put into the market recently, the fuel-saving effect was remarkable, and the user's doubts about the State III machine over the State II machine oil were broken.
The current high domestic diesel moisture content is a big headache for truck drivers. The diesel with high water content is extremely harmful to the fuel system of either State II or State III. To this end, Weichai and European professional companies jointly developed a "water removal filter", a level of water removal efficiency of up to 95%, with the engine equipped with a secondary coarse filter can make the water removal efficiency of 99.99%, greatly improve the spray The service life of the oiler guarantees the safe operation of the diesel engine. "Water removal filter" has four advantages: First, efficient oil-water separation function, allowing users to rest assured that the use of domestic diesel with high water content; Second, easy to use, rest assured that the filter installed in the obvious position of the vehicle frame, with Large-capacity transparent cup for the driver to observe the water level and release water; Third, the performance is reliable and low temperature performance is good; Fourth, dual insurance with hand pressure pump, convenient for the driver to exhaust, pump oil.
According to the comprehensive evaluation by the technical development department and users, the WP multi-power fuel-saving switch, “water removal filterâ€, and the Lanqing State III diesel engine of WEVB technology have the best comprehensive performance, and the combined fuel consumption is 2.6 liters/100 km. The rate of blue engine state III that has been put on the market is 63% lower than that of State II; WEVB has increased braking efficiency by 55%; user operating costs can save 25,000 yuan a year.
Also relying on the advanced platform of the electronically controlled high pressure common rail system, Weichai Power has developed an oil-saving constant temperature fan and an oil-saving and broken cylinder technology (fuel-saving “1+1â€). The combination of the two technologies can reduce vehicle fuel consumption by 8%-15. %.
The fuel-saving fan is an ECU that monitors the water temperature and other parameters of the diesel engine in real time. Under the premise of keeping the water temperature of the diesel engine at a constant temperature of 90°C, the temperature of the fan can be dynamically adjusted to effectively reduce fan power consumption and reduce fuel consumption. It has the following advantages: First, it saves fuel and saves 6-10% more fuel than rigid fans. In the process of starting the warm-up of the vehicle, the ambient temperature is low, the idling at the original location, the high-speed driving of the straight road surface, etc., the fuel-saving thermostatic fan has a better fuel economy effect; the second is the adaptability, regardless of the cold zone or the tropical zone. Whether it is winter or summer, the vehicle is well adapted to the environment. If the vehicle starts external loads such as air conditioning, the ECU automatically recognizes and dynamically adjusts the "oil-saving constant temperature fan" speed; third is to improve reliability, "oil-saving constant temperature fan" flexible transmission of torque, reducing the impact load on the pump and belt, effectively improve the The reliability of the water pump and the belt is maintained at a constant working temperature of the diesel engine (90°C), so that the friction pairs of the diesel engine work in the best state, reducing the wear and burning of the oil in the four matching systems. The fourth is the noise reduction and the oil-saving constant temperature. "Fan" operation is gentle, so that the diesel engine speed noise is reduced by more than 2 decibels, driving comfort has been greatly improved.
The advanced diesel fuel-saving cylinder-cutting technology is a fuel-saving technology that Weichai Power has pioneered in China. The principle is also based on advanced electronically controlled high-pressure common rail technology. The diesel engine is controlled by internal ECU data and automatically shut off under certain conditions. Cylinder to achieve zero fuel consumption. If the vehicle is taxiing with the gear during driving, as long as the diesel engine rotates at a speed higher than 850 rpm, the diesel engine automatically enters a broken cylinder state and stops the fuel injection.
After the WP multi-power fuel-saving switch, water removal filter, fuel-saving "1+1" and many other technologies fully equipped with the National III diesel engine, compared with the mechanical pump plus EGR system, it is expected that the same power combined fuel consumption can reduce fuel consumption by 15% According to the annual calculation of fuel consumption of 40 liters per year for 80,000 kilometers and 100 kilometers, it can save 4800 liters of fuel for the user in one year, allowing the customer to obtain tangible benefits during use.
In an interview with reporters, Weichai chairman Tan Xuguang stated that good internal strength is the only choice for enterprises to cope with the crisis. The crisis is a turning point. I believe that through this storm, truly powerful companies will surely do a better job. It is precisely because of their hard work, Weichai has successfully achieved industrial upgrading, not only enhancing its independent innovation capability, but also having a brand. Advantages and cost advantages greatly enhance the ability to resist risks.
