Weichai Fuel-Efficient Engine: Highlights of Futian Auman Highway Fuel-Saving Heavy Truck

Futian Auman ETX highway fuel-saving heavy truck has been favored by end-users since it was launched nationwide in mid-September 2011. Foton has also accelerated the progress of distribution across the country. The China Truck Network reporter randomly investigated Jiangxi, Tianjin, and Beijing. Dealers in Shanghai, Shaanxi, etc., according to their reports that the Auman fuel-saving version of the heavy truck has basically arrived, and the number of users for consultation and purchase is also increasing, and Weichai fuel-efficient engines are the most valued performance characteristics of users.

"Now the oil prices are high, and users are not too overloaded. Trucks can save fuel. They are the most concerned factor. This oil-saving version of the 380,340-horsepower log-chasers has a very good intention of buying, and is very appreciative of Weichai engines." Deng, General Manager of Jiangxi Gao'an Jinda Automobile Trade Co., Ltd. said to the China Truck Network reporter. According to the statistics of the survey data, the proportion of the carriage of dangerous goods in the transport of dangerous goods is now 100%. The proportions of the standard transportation such as distribution and coal transportation are all over 80%, and the fuel expenditure accounts for 34% of the total transportation cost. It accounts for 70% of the controllable costs. Therefore, the original drivers who relied on the overload limit to compensate for the loss caused by high fuel consumption have begun to consider replacing the more fuel-efficient and more economical models under the state of loading, the Auman ETX Highway Festival. The oil heavy truck comes out with the flow.

Auman Road Oil-saving version of heavy truck system fuel economy is really saving

The China Truck Network reporter learned that Auman Highway Fuel-saving Edition heavy-duty trucks innovation can achieve systemic fuel economy, saving 10%-13%, equivalent to saving more than 40,000 yuan per year for users. It is reported that the car adopts a platform and modular design. While designing to reduce its own weight, it adopts an all-aluminum transmission and reduces the weight of the vehicle by reducing the use of new materials such as lightweight saddles, few leaf springs, and vacuum tires. In the loaded state, it can carry more cargo. Through the optimization of structural design of the vehicle, a new lightweight material is selected, and the total weight of the entire vehicle is reduced by 800 kg. The minimum weight of the 6*2 models is 7.41 tons, and the minimum weight of 6*4 is 8.17 tons, which is lower than the industry average.

In addition, Auman highway fuel economy heavy trucks are specifically designed and matched for road users. Powertrains and transmission systems have been optimized and matched to save fuel, using low-speed high-torque engines, 12-speed transmissions with overdrive transmissions and 4.11 rear axles with a small speed ratio. In addition to improving the dynamics, the common vehicle operating conditions are promoted to operate in the low fuel consumption area of ​​the engine. On the other hand, vehicle accessories are more fuel-efficient through optimized matching. During the interview, the reporter learned that, besides being satisfied with the vehicle's light weight and fuel economy, Weichai fuel-efficient engines have become the biggest bright spot to attract users.

Weichai Fuel-Efficient Engine Becomes the Highlight of Heavy Truck Trucks

Manager Zheng of Tianjin Jiayi Shengda Automobile Co., Ltd. also agreed with Deng. “The Auman Highway Fuel Saving Edition has come to our store in September. Users have long recognized Weichai Engine and heard of Weichai this time. The engine can also save fuel more directly from the store to buy a car, and the salesperson does not need to promote the Weichai engine any more.” What aspects of the Weichai fuel-efficient engine are optimized and improved?

China Truck Network reporter learned that since the engine upgrade of Weichai Blue Engine II in September 2010, it has been approved by more and more users. Weichai fuel-efficient engines have four major performance optimizations and four major upgrades to achieve fuel-efficient power.

Among them, engine performance improves fuel efficiency through four major optimizations, resulting in better fuel economy. Including: low-speed and more fuel-efficient, the engine rated speed is reduced to 1900 rpm, operation avoids the high fuel consumption area, and more operation in the economic fuel consumption area; large torque and more fuel-efficient, on the basis of the original 1900 rpm products, Auman Road The fuel-saving version also optimizes the engine, the maximum torque is increased to 1900N.m, accelerates the overtaking ability, and the fuel consumption of the vehicle is further reduced. In addition, for the high-speed logistics vehicle operating conditions, the Auman Highway Fuel Saving Edition also adopts a soft fuel environment. Improvement of hardware, broadening low fuel consumption areas and improving fuel efficiency. At the same time, second-generation BOSCH high-pressure oil pumps provide fuel pressures in excess of 1600 bar, which precisely control fuel injection and reduce waste to achieve fuel economy.

In addition, Weichai fuel-efficient engines are also equipped with four major upgrades to reduce overall fuel consumption. First of all, "do not allow the fan to charge you oil", the electromagnetic constant temperature fan can automatically control the fan speed according to the diesel engine water temperature, effectively reducing the fan's useless power consumption; Secondly, "no more fuel-efficient, no fuel," the fuel oil Hanbao electric pump oil , heating wax solution, water removal filter in one of the three functions, fast exhaust, easy to start, reduce the fuel system failure rate; the same time, "the engine power can be adjusted more fuel-efficient", configure WP multi-function fuel switch, driver according to no-load The different road conditions, medium load and heavy load, the independent choice of engine power, the reduction of additional power consumption, and the reduction of fuel consumption of the entire vehicle are as if a vehicle is loaded with three engines and can be changed randomly; in addition, “the piston will not charge you for oil” The use of fuel-efficient air compressors requires only a small amount of fresh air to be drawn into the air intake chamber during operation to reduce the piston's workload and reduce power consumption.

Weichai Power Co., Ltd. and Futian Auman also conducted several joint tests in order to achieve more systematic fuel economy, and optimized the vehicle accessories such as air filters, intercoolers, and mufflers. Among them, the flow rate of the air filter is increased to 2100m3/h, reducing the intake resistance improves the fuel combustion efficiency; the exhaust pipe diameter of the engine is changed to 120mm, the exhaust gas back pressure of the engine is reduced by 38 to 40%, and the engine is reduced Power consumption of the exhaust system.

As Deng Deng said: In the context of high oil prices and poor transportation environment, Weichai fuel-efficient engines have brought more fuel-efficient and more economical transportation to end-users.
