LPI SYSTEM FOR GAS VEHICLE AND SOLENOID VOLTAGE CONTROL METHOD THEREOF

摘要

PURPOSE: An LPI system for a gas vehicle and a solenoid voltage control method thereof are provided to minimize the heating value of a cut solenoid valve by applying minimum driving voltage to the cut solenoid valve. CONSTITUTION: An LPI system for a gas vehicle comprises a cut solenoid valve(10), a drive unit(20), and a control unit(40). The cut solenoid valve is installed in a multi-valve and selectively blocks fuel supplied from a bomb to a fuel pump. The drive unit powers the cut solenoid valve. After the pre-set initial starting time of the cut solenoid valve passes, the controller generates a drive control signal and repetitively drives the cut solenoid valve.
