GEHRING / Non-Cylindrical Honing
Reducing friction loss in internal combustion engines through non-cylindrical honing processing.
Gäuling's Non-Cylindrical Honing (FormHoning) Gäuling has developed a honing method that takes into account the distortion during engine operation, rather than manufacturing cylindrical bores. The distortion of the bore shape is countered by creating an inverted shape through the FormHoning method, maintaining a cylindrical shape even during operation. [Features] ■ FormHoning Light simulates the thermal distortion inside the bore during engine combustion and is a technology that intentionally hones the bore shape into various non-cylindrical shapes. ■ By processing the bore into a non-cylindrical shape with FormHoning Light, the contact between the piston skirt and the bore during combustion is reduced, thereby decreasing friction. ■ FormHoning Professional utilizes a special honing tool equipped with an expansion mechanism using piezo elements to optimize local piston clearance and reduce bore deformation caused by static and thermal distortion. This achieves a cylindrical bore without distortion even during engine combustion, reduces ring tension, and decreases friction resistance between the piston skirt and cylinder bore, as well as CO2 emissions.
