1. 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.
2. 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.
3. 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.
4. 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.
5. Advanced Holset turbocharger and after-cooled technology, pulse exhaust manifold reduce exhaust temperature, provide excellence fuel consumption and emission performance.
