Shangchai has always been committed to the research and development and production of internal combustion engines. It has been at the forefront of the national industry in terms of technological progress, product innovation, improvement of process quality, and scale of the company. Especially in the field of construction machinery, it has been designed and manufactured by China since 1958. The first 6135 diesel engine, which pioneered China's medium-bore diesel engine, has laid a foundational position in the engineering industry. Shangchai is still one of the most important suppliers of domestic construction machinery power.
Shanghai Diesel Co., Ltd. was established in 1947, formerly known as China Agricultural Machinery Corporation Shanghai Wusong Agricultural Machinery Repair Factory. At that time, it was also affiliated with four family factories, mainly engaged in the repair of agricultural machinery and equipment. After the founding of the People's Republic of China, it was renamed Wuye Machine Factory. In August 1953, it was officially named Shanghai Diesel Engine Factory. In 1993, it was restructured into a joint stock limited company and was renamed Shanghai Diesel Engine Co., Ltd.
Today, the company already owns three series diesel engines, including D114, C121, and 135 (G128), and its full power coverage is 60 to 420HP. The products are mainly used for commercial vehicles, construction machinery, ships, and self-powered power stations. Based on existing products, the company has also developed new products such as LPG, natural gas, dimethyl ether, and dual-fuel engines to enhance the company's ability to cope with energy shortages and sustainable development. Shangchai has grown from an old agricultural machinery repair factory in China to one of the most important internal combustion engine manufacturers in China. After more than 60 years of hardships, Shangchai has written on their long-standing technical quality development history page about their constant pursuit of quality.
Brilliant course
After the founding of the People's Republic of China, it was renamed as Wuchai Machinery Factory's Shangchai Company, which revived a new vitality. It had produced a single-cylinder horizontal 750 rev/min 12HP diesel engine. In 1951, the FM110 series marine diesel engine was successfully manufactured. After officially establishing its name as the Shanghai Diesel Engine Factory in August 1953, it began to design and manufacture diesel engines on its own under the guidance of the principle of "independent, self-reliance". In September 1958, China's first self-designed, fully domestically-produced 6135 diesel engine was born in Shanghai, creating a precedent for the manufacture of medium-power high-speed diesel engines in China, and the first 50 loaders, large bulldozers, and heavy-duty trucks in China. Large-scale construction machinery is equipped with diesel engine 6135, which lays the foundational status of Shangchai in the construction machinery industry. From then on, China’s diesel engine has made every major step forward in the diesel industry. For quite some time, every technological progress and product innovation of Shanghai Diesel Engine Factory is almost equivalent to a progress made by China in the field of diesel engines. Those classic products familiar to the field of construction machinery are still unforgettable.
