LIQUEFIED-PETROLEUM-INJECTION SYSTEM FOR VEHICLE

摘要

PURPOSE: A LPI(Liquefied Petroleum Injection) system for vehicles is provided to improve the delivery efficiency of fuels by expanding a diameter of a flow path, in which a same size coil and plunger open and close. CONSTITUTION: A LPI(Liquefied Petroleum Injection) system for vehicles comprises a bombe, a fuel pump, and a fuel cutoff valve. A flow path for fuels is formed in the bombe. A fluid chamber having an inlet and outlet for the oil is formed in the flow path. The fuel cutoff valve comprises a coil, a first plunger(20), and a second plunger(10). The first plunger moves up and down according to electricity applied by the coli. The second plunger is placed at the end of the first plunger with being inserted into the fluid chamber with the pipe form. One side of the second plunger comprises a small diameter part, and the other side comprises a large diameter part.
