Key Features

• Proven Mitsubishi Reliability: The 6D34 engine features a robust cast iron block and cylinder head. It is designed for continuous heavy-duty operation in demanding construction environments. Many of these engines run for 15,000‑20,000 hours with good maintenance.

• Turbocharged and Intercooled: The turbocharging system forces more air into the cylinders for increased power output. The intercooler reduces intake air temperature for more efficient combustion. This delivers strong low-end torque for digging and lifting operations.

• Direct Injection System: The engine uses a direct injection combustion system. This provides better fuel efficiency and cleaner operation compared to indirect injection designs. The mechanical governor ensures reliable speed control without complex electronics.

• Proven in Major Equipment Brands: The 6D34 engine powers excavators such as the Sany SY215C, Kato HD820III and HD1023III, and Kobelco SK200-6E. Parts and service information are readily available for this engine.

• Fuel-Efficient Operation: With a specific fuel consumption of 225 g/kW‑hour, the 6D34 balances power and fuel economy. This helps lower your operating costs over time, especially for equipment like excavators that run for many hours.

• Fully Rebuilt to OEM Standards: We completely disassemble each engine and rebuild it to original Mitsubishi factory specifications. We recondition the cylinder head and inspect the cylinder block. We service the fuel injection pump and turbocharger. All critical wear parts are replaced with new components.
