A fuel supply apparatus for a Gasoline Direct Injection (GDI) engine having reduced pressure pulsation includes low and high pressure fuel pumps, connected via a fuel supply line, a pressure sensor and a pulsation relief valve installed between the pressure sensor and the high pressure fuel pump. The pulsation relief valve includes a check valve part allowing the fuel to flow in a normal direction from the low pressure fuel pump to the high pressure fuel pump but not in a reverse direction, and an orifice part which is installed substantially in parallel to the check valve part and is configured to allow the fuel to flow in both directions, wherein an amount of the fuel flowing through the orifice part is less than an amount of the fuel flowing through the check valve part in the normal direction.

Fuel supply apparatus for GDI engine having reduced pressure pulsation

Provided is a method for controlling evaporation gas treating apparatus that can effectively prevent evaporation gases from leaking out of a vehicle with minimizing power consumption of a battery in the vehicle and improving efficiency of purging the evaporation gases, by selectively operating a heater for when a large amount of evaporation gases are contained in active carbon of a canister.
