Hangfa "European III machine" officially put on the market
China National Heavy Duty Truck Group Hangzhou Engine Co., Ltd. has always been known as the "cradle of heavy-duty diesel engines in China" in the automotive industry. In 1964, the company independently developed and developed the first 6120 high-speed diesel engine in China, which was used for the “Yellow River†8-ton heavy-duty truck and the 12-meter chassis “Yellow River†bus. In 1983, the company developed itself. The X6130 series diesel engine developed has realized the leap of diesel engine upgrade in China. In 1984, the company introduced the WD615 series diesel engine from Austria Steyr. After years of digestion, absorption and improvement, it has become a similar product in mass production in China. One of the most cost-effective diesel engines.
In order to meet the market's new demand for diesel engines and national environmental protection requirements, Hangfa Company signed the "Europe III Diesel Engine Joint Development Project" with the British Ricardo Company at the end of 2003 through market research. In 2004, it signed a contract with Japan Denso. WD615 Euro III engine electronically controlled common rail system matching development" contract, jointly develop and develop a new generation of WD615 diesel engine with independent intellectual property rights.
After two years of hard work and trial production, on the eve of the Spring Festival in 2006, the first Euro III engine was successfully launched in the laboratory of the company's technical center, and the vehicle and calibration test work officially began. In order to catch up with the right temperature, the test team raced in less than half a year to complete the task that took a year and a half to complete. On January 27th, the Euro III engine went north to the Mohe River to do the cold zone calibration test; on April 10th, the Euro III engine went west into Qinghai Golmud, and completed the plateau calibration test at the Kunlun Mountain Pass at an altitude of 4767 meters. Then the Euro III engine was non-stop. The road went south and completed the hot zone test in Hainan. In late May, the new model of China National Heavy Duty Truck HOWO with Euro III engine ran for more than 20,000 kilometers and completed a series of calibration tests. During the period, the Euro III engine consistently demonstrated excellent design performance during the test. Whether in the cold region of minus 40 degrees, in the case of severe hypoxia in the plateau, or in the hot and hot conditions in Hainan, the test data has reached the setting requirements of the Euro III engine. Especially in the calibration test of the cold zone, the Euro III machine can start normally in one second in an environment of minus 32 degrees.
After completing the calibration tests in the cold zone, plateau, and hot zone, since the end of May, the Euro III engine has started a series of production line commissioning work. During the period, the relevant departments of the company worked together to ensure that the Euro III engine assembly line was smoothly completed as planned. The technical, electronic and quality assurance expert group of Denso Company confirmed that the production line fully complies with the process requirements. Until July 10, Hangfa Company has assembled two batches of engines for use by China National Heavy Duty Truck Group Corporation and other market users. According to the product development plan, the company will further optimize the production process equipment and equipment guarantee, and make the final sprint for the formation of 20,000 Euro III engine capacity at the end of the year, and realize the mass production of the Euro III engine in the fourth quarter.
Hangfa Europe III engine retains the characteristics of Steyr WD615 main design one cylinder one cover, frame structure, dry cylinder liner, etc., adopts the international most advanced four valves and electronically controlled common rail fuel injection. The engine technology, the design of the emission level, power, fuel consumption, torque and other major technical indicators to achieve the same level of diesel engine international advanced level.
Hangfa Euro III engine has three highlights: one of the highlights, using the world's most advanced design methods and test methods to achieve Euro III, Euro IV emission standards, power 400 horsepower, "B10 life" 12,000 hours, the whole machine The basic goal of noise below 97 decibels is the use of an advanced electronically controlled common rail fuel injection system with a newly designed diesel engine. The current calibration is carried out in accordance with Euro III emission requirements, using only 160 MPa common rail pressure and primary and pre-spray two injections. When the common rail pressure of 180 MPa is enabled and the pilot injection, post injection and late injection have not been used, the same common rail injection system is fully capable of adjusting and calibrating, plus necessary exhaust aftertreatment measures. Meet the requirements for Euro IV emissions to be implemented in the future.
The second highlight is that the new design has been carried out on the basis of retaining the Steyr WD615 Euro II diesel engine, so as not to change the installation and connection dimensions with the vehicle as much as possible, and the good machine layout inheritance, and The original Euro II emission WD615 is basically the same, which greatly facilitates the matching with the OEM. At the same time, it has a good driving control performance, which can save a lot of time, capital and labor investment for users to upgrade new products.
Highlight 3, Steyr WD615 Euro III and Steyr WD615 Euro II engine have 80% of the parts are universal, with good inheritance and versatility, for the manufacturing of the vehicle manufacturer and the maintenance of the end user The purchase of accessories has provided great convenience.
