Advantages of QSKTAA19-G3-NR2-B 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 emission performance. High quality alloy cast iron, one cylinder one head, single camshaft and special designed 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 120 Mpa, which leads to an excellent fuel consumption rate and emission performance. Check valve in fuel tube improve reliability.

  • Gear water pump and great flux channel design provide 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.
