Title:
Liquefied gas fuel supply device
Document Type and Number:
Japanese Patent JP6333703
Kind Code:
B2
Abstract:
A liquefied gas fuel supplying apparatus includes an injector that injects fuel to an engine, a fuel tank that stores the fuel, a fuel pump that pumps the fuel from the fuel tank to the injector, a fuel cooler that cools the fuel that is pumped from the fuel pump to the injector, a fuel temperature sensor that detects a fuel temperature in a pipe, and an ECU. The ECU, during engine operation, estimates the fuel temperature in the pipe after engine stop, based on a detection value detected by the fuel temperature sensor, and performs drive control of the fuel cooler to cool the fuel, when the estimated temperature is higher than a temperature that is evaluated from a predetermined saturated vapor pressure curve.
