We will accelerate the development of large-power domestic heavy-duty vehicles
On October 10, a WD12 diesel engine with the words "the 10,000th WD12 engine" was pulled from the assembly line of the first plant of the Weichai New Power Plant and immediately installed at the plant. It was a memorable moment: Since the official release of Weichai's 60th anniversary on Oct 20 last year, Weichai Power has achieved its production and sales target of 10,000 units of WD12 diesel engines within 10 months this year, marking China's production and sales target. The main driver for heavy vehicles is acceleration from 10 litres to 12 litres.
Our company (www.hf-loaderparts.com) actively prepares for vulnerable parts, air filter, fuel filter, oil filter, pressure sensor, Diesel Engine Oil and so on, ready to serve users.
A year ago, the market didn't know what WD12 was. A year later, sales exceeded 10,000, and only 1,500 in Shanxi. According to people from Weichai Marketing Company, the WD12 market broke the monopoly of foreign brands in the domestic market where the displacement is above 12 liters and the engine is above 380 horsepower, and promoted the accelerated development of China's heavy vehicles. The 12-litre single-displacement heavy-duty engines are now in desperate need of carmakers. From January to September this year, WD12 engines accounted for 12.32% of the power of Weichai's engines above 300 horsepower. Although Weichai Power has repeatedly increased its production plans for WD12 engines, the market situation remains difficult. It is expected to produce and sell 15,000 units in 2007, an increase of nearly 7 times year-on-year. Orders will exceed 30,000 units next year and 50,000 units in 2009.
The new-generation 12-liter WD12 high-power commercial vehicle engine, jointly developed by Weichai Power Co., Ltd. and well-known European research and development institutions, is the flagship product of 300hp and above series diesel engine in 2007, with a power of 336 ~ 480hp, which completely spans the plateau, high temperature and high cold. Extreme test, after more than 50,000 hours of bench test, 86 vehicles road test, as long as 5 years, a total of 50 million kilometers of road test, is a higher level of high-horsepower engine platform after the Steyr platform is the largest domestic commercial vehicle engine. WD12's major economic indicators are among the world's leading. Compared with the domestic existing similar domestic power engine, WD12 engine in the design concept of WD12 engine has more fuel saving, more reliable, stronger, safer characteristics and strong technical advantages.
The WD12 features a specially designed P12 high pressure oil pump with pump pressure up to 1400bar. With the increase of intake air volume, the atomization effect of diesel injection is greatly improved, the combustion is more thorough, and the fuel consumption of the vehicle can be effectively reduced by 10% ~ 15%. If the bicycle travels 100,000 kilometers per year, it can save one engine in three years, which is a considerable benefit.
The WD12 has an output torque of over 1,300 nm at 1000 RPM and a maximum engine torque of 1,950 nm. It also has a wide range of high torque. The vehicle has excellent acceleration performance, high carrying capacity, and extremely efficient operation.
WD 12 litre power is significantly reduced and has an inherent advantage over 9-11 litre engines. After years of market testing, WD12 has low failure rate and high reliability.
WD12 adopts Weichai Power and WEVB exhaust braking technology introduced synchronously in the world. The braking power of the engine can reach 2000 ~ 2500 RPM, and the braking power can reach 160 ~ 230 kW, which can improve the braking efficiency of the vehicle by more than 50% and effectively reduce the braking. The number of times increases the brake safety factor, prolongs the life of the brake system, and increases the driving comfort.
Some experts point out that at present, the European diesel engine is basically about 500 horsepower, and some have reached 600 horsepower. The development trend of large tonnage, large horsepower and large displacement will continue. From the perspective of the domestic market, the rapid development of road construction, the steady progress of the national infrastructure, and the healthy development of China's macro economy will all promote the increasing demand for heavy and high-power heavy trucks and construction machinery. Therefore, in a long period of time, large displacement, high-power engines will become the mainstream of domestic automobile, wheel loader, construction machinery market, and Weichai Power will be the main force.
