PREVENTIVE DEVICE AGAINST HEATING OF LPG REGULATOR IN CAR USING LPG AND GASOLINE JOINTLY FOR FUEL

摘要

PURPOSE:To prevent the bad governing or pressure by arranging a switch valve in circuits of cooling water of an engine for preventing liquid tar from solidification at the tim of driving by gasoline. CONSTITUTION:A switch valve 10 is arranged in cooling water circuits 5 and 6 provided between an engine 1 and an LPG regulator 2. In this construction, for driving by LPG, the switch valve 10 is opened, and the heated cooling water of the engine is made to circulate in the LPG regulator 2. Meanwhile, for driving by gasoline, the switch valve 10 is closed, and the heated cooling water of the engine is prevented from circulating in the LPG regulator 2. Consequently, at the time of driving by gasoline, the LPG regulator 2 can be prevented from rising to a high temperature inside for preventing the bad governing of pressure without the solidification of liquid tar.
