For many years, Yuchai has been a pioneer in the production of engines for all significant forms of transportation. In China and most Asian nations, Yuchai engines are found in more than automobiles.
The Yuchai YC6108G engine powers all contemporary three-ton wheel loaders (YC6B125 is the same engine but with a different marking). The narrative is the same for forklifts. However, there are several engine options: The most popular engines for this kind of specialized equipment are the YC4108 and YCD4J22G.
The Yulin Quantang Industrial Cooperative was founded by the Chinese government in Yulin City, Guangxi Province, in July 1951. This company, Guangxi Yuchai Machinery Group Co., Ltd., was the precursor of the contemporary diesel engine factory.
The business was first set up as an agricultural firm, with the manufacturing of agricultural tools and units, auto repair, the processing of mechanical components, and the creation of low-power machinery among its primary duties.
The Yuchai factory didn’t take the first step toward becoming one of the biggest producers of diesel engines until 1959, eight years after the start of construction. The first Yuchai 2105 diesel engine was created and put into mass production, and for the ensuing 22 years, it dominated the market.
The YC6105Q and YC6105QA engines were introduced in the 1980s; the latter was a significant breakthrough and launched a new line of Chinese engines with direct injection technology.
Later, in 1991, the YC6105QA diesel engine was replaced with the YC6105QC, which was newer and more technologically sophisticated. And during the following ten years, he ended himself with a sizable portion of the Chinese engine market.
Since then, Yuchai has created a vast array of engines and put them into mass production, including the YC6108G diesel engine, which is the most well-known and frequently used in Chinese special equipment. There are dozens, if not hundreds, of state honors and medals for achievement in the engine and special equipment industries. Additionally, the engine construction industry’s top engineering research facility opened its doors in July 2007.
The Yulin Quantang Industrial Cooperative was founded by the Chinese government in Yulin City, Guangxi Province, in July 1951.
The first Yuchai 2105 ICE was created and put into industrial production in 1959.
A technical research facility that leads the engine manufacturing sector opened its doors in July 2007.
The most comprehensive selection of engine components and accessories in China, as well as internal combustion engines for Chinese wheel loaders, forklifts, excavators, and mini-equipment that meet European specifications, is all about Yuchai.
