This engine is the standard power unit for the TY230 and is also compatible with other heavy equipment such as the Shantui SD22 series .
1. Installation Location
This engine is installed in the rear engine compartment of the TY230 bulldozer, mounted to the main frame. It is coupled to a hydraulic torque converter and a planetary gear transmission, which transfer power to the final drives and tracks . The engine is secured using dedicated mounting feet and a flywheel housing designed for direct fit .
2. Function
The engine provides mechanical power for both travel and working operations. It drives the hydraulic system that operates the bulldozer's blade lift, tilt, and ripper functions through a gear pump . The engine delivers a rated power of 169 kW (230 hp) at 2000 rpm, with a maximum torque of approximately 1033 N·m at 1400 rpm . Its turbocharged design maintains rated power output even at altitudes up to 3000 meters without adjustment .
3. Maintenance and Service
The engine requires regular maintenance including oil and filter changes, coolant level checks, and inspection of the turbocharger and fuel system. It uses a PT fuel injection pump, which requires proper adjustment and clean fuel to operate reliably.
