1915300 / 19.15.300 SFGLD piston
The 19.15.300 piston is a precision-engineered component designed specifically for Guascor SFGLD gas engines. Built to withstand extreme combustion pressures and high thermal loads, this piston ensures stable engine operation, high efficiency, and long service life in continuous-duty power generation applications.
This piston is suitable for use in biogas, natural gas, landfill gas, and CHP (Combined Heat & Power) installations where reliability and durability are critical.
Application: Guascor SFGLD gas engines
Product Type: Engine piston
Engine Class: Industrial gas engine
Condition: New / OEM-compatible / OEM available
Usage: Power plants, biogas engines, cogeneration systems
The 19.15.300 SFGLD piston features a specially engineered combustion bowl geometry, developed to optimize the air–fuel mixing process inside the cylinder.
Improved air turbulence and swirl
Enhanced fuel atomization
Faster and more uniform combustion
Reduced knocking and detonation
Higher thermal efficiency and power output
The optimized bowl shape plays a crucial role in controlling flame propagation, ensuring stable combustion and reduced mechanical stress on engine components.
Industrial SFGLD engines operate under sustained high temperatures. To manage this, the piston is designed for active oil cooling, where pressurized lubricating oil is sprayed onto the piston underside or circulated through internal oil galleries.
Lower piston crown temperatures
Reduced thermal fatigue
Extended piston and cylinder liner life
Improved engine reliability under high load
The 19.15.300 piston is manufactured using high-grade alloy materials capable of withstanding:
Extreme combustion pressure
Continuous thermal cycling
Mechanical stress from long operating hours
Strict dimensional tolerances ensure:
Accurate piston-to-liner clearance
Reduced blow-by
Lower oil consumption
Smooth and vibration-free operation
This piston is also available in OEM configuration, manufactured by Mahle, the original equipment supplier for Guascor pistons.
Mahle pistons are globally recognized for:
Advanced metallurgy
Precision machining
High resistance to wear and thermal deformation
Proven reliability in industrial gas engines
Guascor’s collaboration with Mahle ensures consistent quality and performance across both new and legacy engine platforms.
For optimal engine performance and long-term reliability:
Piston inspection: During major overhauls
Piston replacement: As per OEM R3 service interval or when wear limits are exceeded
Always replace piston rings when installing a new piston to ensure correct sealing
Service intervals may vary depending on fuel quality, load profile, and operating environment.
The 19.15.300 piston remains fully supported for older and legacy Guascor SFGLD engines. Availability of this piston ensures:
No engine redesign or modification
Retention of original combustion characteristics
Cost-effective maintenance solution
Extended operational life of existing engine assets
This is especially important for operators managing long-running installations with controlled maintenance budgets.
