Performance Features

■ Cummins patented technologyPT Fuel System, ultra-high injection pressure, ensures excellent atomization and complete combustion for the engine.

■ Holset exhaust gas turbochargers provide more complete intake, enhancing efficiency and further improving combustion, while reducing engine fuel consumption rate.
■ Air-to-air cooling technology ensures more complete intake and better fuel economy.
■ STC's timing system ensures better combustion under both high and low load conditions.

■ Replaceable wet cylinder liners with excellent heat dissipation and easy replacement.
■ All models have strong general applicability in parts, high series level, and convenient maintenance.

■ The cylinder block and cylinder head both feature internal pressure lubrication channels, offering a compact structure with low failure rates.
