QSNT-C500 Industrial Engine

CCEC QSNT-C500 (2000 RPM) Industrial Engine is 6-cylinder inline, 14 liters four-strokes engine with 140 mm (5.5 in) bore and 152 mm (6.0 in) (5.98 in) stroke.

QSNT-C500 Industrial Engine equipped with CELECT Fuel System, comes with turbocharger and charge air intercooler, Engine Emissions Meets ECE R96H Stage IIIA. The rated power of the CCEC QSNT-C500 industrial engine is 500 HP (373 kW) at 2000 RPM, and the maximum torque of the engine at 1400 RPM in this mode is 2100 N.m(1549 lb.ft).

To achieve different output, CCEC QSNT series Industrial engine have three configurations which are turbocharged engine, turbocharge with water-air intercooler, turbocharge with air-air intercooler. In the detailed model name, code T means engine come with turbocharger, code single A means engine comes with water-air intercooler, and code double A means engine comes with air-air intercooler.

As part of EMAC, ConeMac provides industrial power pack solution that integrated with air intake, air exhaust, cooling system, control system, transmission and hydraulic accessories, We also supplying special products such as explosion proof engine, generator and water pump set, as well as ultra-low temperature condition engine power pack.

Advantages of CCEC QSNT-C500 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.
