Product Overview – SFGLD Piston 19.15.300

• 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

Engineered Combustion Bowl Design

The 19.15.300 SFGLD piston features a specially engineered combustion bowl geometry, developed to optimize the air–fuel mixing process inside the cylinder.

Key Design Advantages:

• 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.

Thermal Load Management & Piston Cooling

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.

Benefits of Oil-Cooled Piston Design:

• Lower piston crown temperatures

• Reduced thermal fatigue

• Extended piston and cylinder liner life

• Improved engine reliability under high load

Material Quality & Manufacturing Precision

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

OEM Option – Mahle Manufactured Pistons

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.

Recommended Service & Replacement Guidelines

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.

Support for Legacy SFGLD Engines

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.
