1. Development History Of The Weichai Engine
The history of the Weichai engine can be traced back to 1946, and its predecessor was a weapons repair factory established in Weihai.
In 1947, Weichai began to imitate diesel engines and embarked on the journey of engine manufacturing. After that, in 1953, the enterprise was renamed Weifang Diesel Engine Factory, and it kept exploring and making many types of engines in succession; in 1956, it introduced the 80KW 6160 medium-speed diesel engine technology from Czechoslovakia, and in 1983, it introduced the “Steyr” heavy-duty automobile engine technology from Austria, which were two important technological introductions, providing a good opportunity for Weichai to develop its business in the field of diesel engine manufacturing. These two important technology introductions provided a strong boost to Weichai’s technology accumulation and product upgrading.
By 1998, Weichai faced severe business difficulties, with debts amounting to more than 300 million dollars, and salaries being suspended for more than half a year. Under the leadership of Tan Xuguang, Weichai quickly turned losses into profits and paid off all debts in 2000.
In 2005, Weichai launched the high-horsepower high-speed electronically-controlled Blue Engine with independent intellectual property rights, a milestone product that completely reversed China’s long-term dependence on imports of high-speed high-horsepower engines. Since then, Weichai has continued to make great efforts, launching the Weichai WP13 engine to lead China’s heavy commercial vehicles into the 500-horsepower era, and the H-platform power to set up the highest reliability standard for global heavy-duty engines.
In recent years, Weichai has continued to innovate and made significant breakthroughs in the field of engine thermal efficiency, breaking the world record many times. At the same time, Weichai has actively laid out the new energy field and researched and developed various new energy power assemblies, such as fuel cells and hybrid power, showing strong technical strength and innovation ability. After years of development, Weichai has established a full range of engine products with displacements ranging from 2L – 579L and power ranging from 25 hp – 13600 hp and has become a globally renowned engine manufacturer.
