Product Description
Complete Cylinder Head – Forced Lubricated Version | Guascor Part No. 1911400
Power generation using natural gas, landfill gas, and biogas demands engines engineered for continuous duty, high thermal loads, and long service intervals. The Guascor SFGLD 560 and SFGM560 engines are widely used in renewable energy and CHP applications, and a key component ensuring their durability and efficiency is the complete forced-lubricated cylinder head, Guascor part number 1911400.
This version is specifically designed with forced oil lubrication for exhaust valve guides, making it ideal for high-temperature, high-load operating conditions.
Why the Cylinder Head Is Central to Engine Performance
The cylinder head is a precision-engineered structural and functional component that seals the combustion chamber and supports critical engine systems. It houses the intake and exhaust valves, spark plugs, and fuel injection interfaces, while managing extreme combustion pressure and temperature.
For Guascor SFGLD 560 & SFGM560 gas engines, the forced-lubricated cylinder head is optimized to withstand extended running hours, aggressive exhaust temperatures, and demanding power generation environments.

Functional Role of Cylinder Head 1911400
Combustion Sealing & Compression Stability
Maintains optimal compression, improving engine output, efficiency, and fuel utilization.
Thermal Regulation & Engine Protection
Plays a critical role in heat control, preventing overheating and safeguarding the engine from thermal damage.
Optimized Air-Fuel Management
Accurate valve and injector positioning ensures efficient air-fuel mixing, cleaner combustion, and reduced emissions.
Special Design: Forced-Lubricated Exhaust Valve Guides
Forced Oiling System for Exhaust Valve Guides
Guascor engines equipped with forced-lubricated cylinder heads use a dedicated oil supply system for exhaust valve guides, specifically engineered to handle extreme exhaust temperatures.
Unlike conventional valve guides that rely on passive lubrication, this system actively delivers pressurized oil through internal channels directly to the valve stem and guide interface.
How the Forced Lubrication System Works
Continuous Oil Supply
Pressurized oil flows through the valve guide, ensuring constant lubrication of the valve stem and guide surface.
Superior Lubrication
Reduces friction and wear, minimizing the risk of valve sticking, scuffing, or premature failure.
Improved Cooling
Oil acts as a heat transfer medium, removing excess heat from the exhaust valve and guide, preserving metallurgical integrity.
Enhanced Engine Reliability
By controlling friction and temperature, the forced oiling system allows the engine to operate reliably under high thermal loads and continuous duty cycles.
This design significantly improves the durability, reliability, and service life of the exhaust valve train, making it ideal for biogas and CHP applications.
When to Replace the Cylinder Head
Cylinder head inspection or replacement is recommended if you observe:
-
Cracks, distortion, or warping
-
Oil or coolant leakage near the head gasket
-
Reduced engine performance or efficiency
-
Recurrent overheating or abnormal temperatures
Replacing a worn unit with a forced-lubricated Guascor cylinder head (1911400) restores engine reliability and prevents costly unplanned downtime.
Conclusion
The Complete Cylinder Head – Forced Lubricated Version (Guascor 1911400) is a critical component for maintaining the performance, efficiency, and longevity of Guascor SFGLD 560 and SFGM560 gas engines. Its advanced forced oiling design, precision reconditioning, and exact engine compatibility make it the preferred choice for operators in biogas, CHP, and power generation sectors who demand long-term reliability and high operating efficiency.
