SDEC has been devoted to manufacturing engines for the engineering machinery industry for nearly six decades. It is one of the strongest enterprises specializing in engine R&D and manufacturing. SDEC has been supplying professional engine kits to earthwork machinery, building machinery and road machinery equipment home and abroad. The first loader, first bulldozer and first road roller made by Chinese manufacturers were all equipped with SDEC engine products.

Application fields of SDEC\'s products in engineering machinery products are extensive, involving products such as loader, bulldozer, land leveler, crane, road roller, paver, tractor and various engineering machinery, with a power range of 100-350 horsepower, covering more than 70% of Chinese engineering machinery products. Since October 2008, China has implemented the national standard of "Limits and measurement methods for exhaust pollutants from diesel engines of non-road mobile machinery". The C and D series products of SDEC, engaged in the engineering machinery industry over a long period of time, all meet the requirements of Stage II emission standard of Limits and Measurement Methods for Exhaust Pollutants from Diesel Engines of Non-Road Mobile Machinery of China. Our product can easily reach the Stage III emission standard. Its C and D series products conform to the EU Directive EEC97/68 and reach the non-road Stage III Level A standard.

SDEC will keep on supplying special power to engineering machinery products and will continue working on developing and producing more reliable, economical, environmentally friendly and effective engines available for engineering machinery products.
