Key Features
Advanced Common Rail Fuel System
The D06FRC-TAA engine incorporates a high-pressure common rail fuel injection system that provides precise control over injection timing and fuel quantity. This results in optimal combustion efficiency, reduced emissions, improved fuel economy, and quieter engine operation.
Turbocharged with Air-to-Air Aftercooling
The TAA (Turbocharged, Aftercooled Air-to-Air) system forces compressed intake air through an air-to-air intercooler before entering the combustion chamber. This denser, cooler air charge enables more complete combustion, resulting in higher power output and better fuel efficiency.
Robust 6-Cylinder Design
The inline 6-cylinder configuration provides inherently balanced operation with minimal vibration, contributing to longer component life and operator comfort. The engine is designed for the high cyclic loads typical of excavator applications.
Tier 3 / Stage IIIA Emissions Compliance
The D06FRC-TAA engine meets Tier 3 and Stage IIIA emissions standards, making it suitable for operation in regions with moderate emissions regulations without requiring complex after-treatment systems.
Durable Construction
Built with high-quality materials and precision machining, the D06FRC-TAA engine is designed to withstand the demanding conditions of construction sites, including dust, temperature extremes, and continuous operation.
Compatibility
This engine assembly is specifically designed for the following SANY excavator models:
Also Suitable For:
Part Number Reference: D06FRC-TAA
Also Known As: Mitsubishi D06FRC Engine, SANY Excavator Engine, SY245H Power Unit, Diesel Engine Assembly

Applications Beyond Excavators
The D06FRC-TAA engine is also used in other heavy equipment applications:
Signs Your Engine Assembly Needs Replacement
Consider replacing your D06FRC-TAA engine assembly if you observe:
-
Excessive Oil Consumption: The engine consumes more oil than normal between service intervals, indicating internal wear.
-
Loss of Power: Reduced digging force, slower travel speeds, or difficulty maintaining engine RPM under load.
-
Excessive Smoke: Black, white, or blue smoke from the exhaust indicates combustion issues, worn rings, or fuel system problems.
-
Unusual Noises: Knocking, tapping, or grinding sounds from the engine block indicating internal component failure.
-
Hard Starting: Extended cranking time before engine starts, especially when cold.
-
High Operating Hours: Engines beyond recommended overhaul intervals (typically 8,000-12,000 hours) may benefit from replacement.
-
Catastrophic Failure: Cracked block, seized rotating assembly, or major internal damage makes replacement more cost-effective than repair.
-
Common Rail System Failure: Extensive fuel system damage may warrant complete engine replacement.
