Description
The SC series heavy equipment engine is regarded as the top choice for construction machinery, due to its reliability. With a power range of 135 KW to 235 KW, it satisfies Tier III emission standards, making it the preferred power choice for Malaysia exported construction equipment and top domestic customers.
This SC series engine incorporates the 3306 series diesel engine technology from the American company CATERPILLAR and also introduces the main processing, inspection and testing equipment of this series of products. In 2006, our company worked with the German company FEV to upgrade this engine series, thus improving its performance, reducing fuel consumption and meeting higher emission requirements. This achieved a combination of adaptability, economy and high reliability. The cost performance of this product was also improved, making it a popular choice on the market.
