Cummins KTA38 Features
■ Head and Valve
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 on head, single camshaft, and a special design outline for better reliability and durability.
■ Crankshaft and Rod
Robust and fully balanced crankshaft design for a more steady rotation and higher strength. Steel piston crown with oil gallery and aluminum skirts for better durability and low oil consumption.
■ Lubrication System
Great flux gear pump, lube oil filter and by-pass oil filter can separate impurities above 10um effectively. Keep the lubrication system in good state and make the engine more reliable.
■ Cooling System
Great water pump and great flux channel design provide effective cooling. Spin-in water filter makes the coolant clean and keeps it in normal acidity.
■ Exhaust System (After-cooled)
Advanced Holset turbocharger and water-air after cooler technology, pulse exhaust manifold, reduce exhaust temperature, provides excellent fuel consumption, and emission performance.
