D Series Diesel Engine for Construction Machinery

Description

The SDEC D series engine features a high reliability and low fuel consumption, and is a recently designed engine that features advanced technology, making it one of the most popular engine series on the domestic market. Its maximum torque reserve is as high as 40% and the power ranges between 105KW to 275KW, meeting China III off-road emission standards.

The prototype engine of the D series was designed together with the Austrian company AVL, based on Chinese oil quality and user application habits. In 2005, SDEC worked with the American Southwest Research Institute (SwRI) to improve the reinforced design and four valve upgrade. It is designed based on American heavy duty diesel engine standards, and is an environmentally friendly power source, meeting higher emission standards. This engine series has sold for more than 20 years, with upwards of 1 million sets currently in circulation.
