Product Introduction

• Structure: A heavy-duty cast-iron block with six cylinder bores, precision-machined for piston fit. It features integrated main bearing saddles, coolant jackets, and oil galleries, along with mounting points for the cylinder head, crankshaft, and auxiliary components.

• Performance: The high-strength cast-iron construction withstands extreme combustion pressures and thermal loads, ensuring dimensional stability and long service life. The precision-machined surfaces and integrated passages ensure optimal coolant flow and lubrication for reliable engine operation.

• Design: Directly interchangeable with original equipment cylinder blocks, supplied with pre-installed core plugs and ready for assembly with internal engine components.

Core Function

1. Structural Foundation: Provides the rigid framework that supports all major internal engine components, maintaining precise alignment of the crankshaft and cylinder bores.

2. Thermal Management: The integrated coolant jackets circulate coolant around the cylinder bores, dissipating heat to prevent overheating and maintain optimal operating temperatures.

3. Lubrication Distribution: Internal oil galleries deliver pressurized oil to the crankshaft bearings, cylinder walls, and other moving parts, reducing friction and wear.
