CAT diesel engine new cylinder block is the "framework" of the engine, undertaking key functions of supporting piston reciprocating motion, sealing the combustion chamber, and transmitting power, directly affecting engine stability and service life. It is made of high-strength vermicular graphite cast iron or alloy cast iron, precision-machined by CNC machine tools, with cylinder bore roundness error ≤0.005mm and flatness ≤0.02mm/100mm, ensuring tight fit with pistons and cylinder heads, reducing the risk of air leakage and oil consumption.
The cylinder block is compatible with mainstream diesel models such as CAT 320D, 336D, C13, and C15. Its internal water jacket and oil passage layout are optimized to improve cooling and lubrication efficiency, withstanding burst pressure above 180bar, suitable for heavy-duty operating environments. Original cylinder blocks strictly follow CAT manufacturing standards, with raw materials and processing technology fully matching the original engine, suitable for scenarios with extreme performance requirements; Aftermarket cylinder blocks pass third-party mechanical property tests, with key parameters up to standard, priced at only 65%-75% of the original, meeting replacement needs of budget-conscious customers.
As a professional supplier, Ningbo Qiuning Trading Co., Ltd. has a complete quality inspection process, ensuring each cylinder block is accompanied by material certificates and precision test reports.
