170F Piston Assembly: The "Power Compression Core" of 170F Engines

The 170F Piston Assembly is the "power compression core" of 170F diesel/petrol engines, designed for sealing and power needs in high-load operation. Its piston body is made of high-strength aluminum alloy with a tensile strength of 350MPa—20% lighter than ordinary aluminum pistons, while withstanding 300℃ combustion chamber high temperature without deformation during long-term operation.

The matching high-carbon steel piston rings are quenched, with a surface hardness of HRC58 and a friction coefficient of only 0.07 against the cylinder wall, reducing wear rate by 50%; the copper alloy piston pin has 40% better thermal conductivity, quickly dissipating heat from the piston head to avoid ablation caused by local overheating.

Old piston assemblies often have "insufficient compression" and "power attenuation" due to ring wear and piston deformation. After replacing with the 170F Piston Assembly, the engine compression ratio returns to the design value of 18:1, power output increases by 25%, and operating noise drops by 12 decibels.

Whether for continuous power generation of generators or high-load water pumping of water pumps, the 170F Piston Assembly ensures efficient combustion chamber sealing and stable power output with "lightweight + temperature resistance + high density" performance, being a key component for reliable operation of 170F engines.
