Pulsation Reduction Fuel Rail "UFRID"
It is possible to effectively dampen combustion pressure pulsations with the rail itself.
The application of returnless systems is expanding as a measure to reduce fuel vapor emissions in gasoline engines. Consequently, fuel pressure pulsations are increasing, making a pulsation damper necessary. UFRID can effectively dampen fuel pressure pulsations within the rail itself, preventing unpleasant cabin noise induced by fuel pressure pulsations without the need for a pulsation damper. By making the rigidity of the rail smaller than the bulk modulus of the fuel, it effectively absorbs the energy of the pulsations generated during fuel injection while ensuring the strength required for the rail. 【Features】 ○ Eliminates the need for a pulsation damper by adopting UFRID ○ Contributes to reducing system cost and weight For more details, please contact us or download the catalog.
