Silindrite plokk Komatsu 6D107 tüübi jaoks ehitustehnika

The Komatsu 6D107 series engine has established itself as a benchmark power platform for medium-sized construction machinery (such as 20-ton class excavators) thanks to its exceptional reliability and superior power density. It delivers not only outstanding fuel economy but also excellent load response in complex and varied operating conditions. The "Bare Engine Assembly" comprises core components—including the cast-iron cylinder block, reinforced cylinder head assembly, crankshaft, connecting rods, pistons, and camshaft—making it an ideal foundation for complete engine replacement or high-standard, comprehensive overhauls.

Engine Configuration: Inline-6 ​​cylinder, 4-stroke, water-cooled, 6.69L displacement

Cooling System: High-efficiency, heavy-duty water cooling (designed for thermal balance under harsh operating conditions)

Air Intake System: Turbocharged and intercooled (significantly optimizes low-speed torque and overall operational efficiency)

Rated Power: Approx. 110–160 kW (150–215 hp), depending on specific equipment application calibration

Fuel System: High-pressure common-rail electronic fuel injection (precise ECU control ensures optimal injection pressure and fuel atomization, balancing power output with emissions compliance)

Key Advantages:

Precision Electronic Management: Real-time adjustment of fuel injection strategies based on load fluctuations, significantly reducing fuel consumption and engine vibration.

Exceptional Reliability: Inherits Komatsu’s signature heavy-duty design philosophy; core components offer an exceptionally long fatigue life.

Comprehensive Service Network: As a globally mainstream engine model, it benefits from mature diagnostic data and established parts supply channels, ensuring high equipment uptime.

Primary Applications: Komatsu PC200/PC220 series excavators, medium-sized wheel loaders, and various specialized industrial power units.
