Fuel supply device of lp gas internal combustion engine

Abstract

Abstract PURPOSE:To prevent supply of air bubbles to a pump and to heighten the accuracy of measuring fuel by disposing a fuel cooling device between a LP gas fuel tank and a fuel pump. CONSTITUTION:A heat exchanger 9 is disposed between a fuel tank 5 charged with liquefied LP gas and a fuel pump 10. The outside of the heat exchanger 9 is surrounded with an evaporator 14 and the evaporator 14 is connected to a cooling medium supply passage 16 including a solenoid valve 15. In this arrangement, LP gas fuel passing through the heat exchanger 9 is cooled to prevent air bubbles from being supplied to the fuel pump 10 and enable correct fuel measuring.
