Advantages of CCEC QSK38-G4 G-Drive Engine

  • High quality alloy cast iron for the rigidity performance and lower vibration and noise. Wet and replaceable cylinder liners for better heat rejection performance and easier replacement.

  • 4 valves per cylinder, Optimize the mixed level which lead to an excellent fuel consumption rate and emis-sion performance. High quality alloy cast iron, one cylinder one head, single camshaft and special de-signed outine for better reliability and durability.

  • CMS unique PT with fixture and Step Timing control for precise fuel injection make the fuel injection pressure above 120Mpa, which leads to an ex-cellent fuel consumption rate and emission performance. Check valve in fuel tube improve reliability.

  • Gear water pump and great flux channel design pro-vide effective cooling. Spin-in water filter makes the coolant clean and keeps it in normal acidity.

  • Advanced Holset turbocharger and after-cooled technology, pulse exhaust manifold reduce exhaust temperature, provide excellence fuel consumption and emission performance.
