Engineered for Performance & Durability
The Guascor HGM / SFGLD Complete Piston Kit (1915210) is a precision-engineered solution designed to withstand extreme thermal loads, combustion pressures, and continuous operation typical of industrial gas engines used in power generation, biogas plants, and CHP installations.
Each component in this kit plays a vital role in ensuring:
-
High combustion efficiency
-
Reduced oil consumption
-
Stable compression
-
Long engine life
Advanced Piston Design – Combustion Bowl Technology
The 1915023 piston, the core component of this kit, features an advanced combustion bowl design commonly referred to as the “flower-shaped” bowl, used in earlier SFGLD engine generations.
Key Engineering Benefits:
-
Enhanced air-fuel turbulence and swirl
-
Improved fuel atomization and mixing
-
Faster and more uniform flame propagation
-
Reduced knocking and detonation risk
-
Improved fuel efficiency and lower emissions
This combustion bowl geometry ensures controlled combustion, leading to higher power output and smoother engine operation.
Piston Cooling System – Thermal Stress Management
To manage extreme operating temperatures, the piston is actively oil-cooled using a dedicated oil jet system. Pressurized lubricating oil is sprayed onto the underside of the piston or circulated through internal oil galleries, effectively:
-
Reducing piston crown temperature
-
Preventing thermal fatigue
-
Extending piston and ring life
-
Protecting cylinder liner integrity
1915280 Piston Ring Set – Functions Explained
The SFGLD piston ring set (1915280) consists of three precision-engineered rings:
-
Compression Ring
-
Chrome-plated rectangular ring
-
Ensures gas sealing and maximum compression
-
-
Scraper Ring
-
Removes excess oil from cylinder walls
-
Prevents oil from entering combustion chamber
-
-
Oil Control (Greasing) Ring
-
Maintains uniform oil film
-
Controls lubrication and oil return
-
Together, these rings ensure optimal sealing, lubrication control, and reduced wear.
