Fuel pump noise reducer for liquefied petroleum injection vehicle has fuel pump activated by receiving battery power through relay based on the determined condition of liquefied petroleum gas switch and voltage detected through terminal

摘要

A fuel pump, provided in a fuel tank, is activated by receiving battery power through a relay (40) depending on the operation of an interface box electronic control unit (IFBECU) (50) which determines the condition of a liquefied petroleum gas (LPG) switch (10) based on the voltage detected through a terminal (PIN2). An independent claim is included for a fuel pump noise reduction.
