Advantages of CCEC QSX15-C525 Industrial Engine

  • Advanced design and sophisticated manufacturing to adapt to various harsh working conditions! High-strength parts, strong ability to work under heavy loads.

  • Cylinder block and cylinder head adopt integrated design. The occurrence of engine water leakage and oil leakage is prevented, and the parts are about 40 % less than other similar engines. The failure rate is greatly reduced.

  • Using forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and longer service life.

  • The cylinder bore adopts a platform mesh honing design. The perfect geometric structure effectively prevents oil leakage, and the use of advanced technology such as new piston ring components and gasket crimping and molding reduces oil loss.

  • The five key systems of the electronically controlled engine are all developed by CCEC, and have been applied and verified in different fields around the world to ensure the excellent economy and reliability of the product.

  • By optimizing the control strategy and combining with the actual operating conditions of the equipment, the fuel economy can be further improved.
