摘要： A fuel supplying system of an LPI engine is capable of improving performance of a fuel pump by decreasing suction pressure thereof. A fuel supplying system of an LPI engine may include a fuel tank storing fuel, a fuel pump feeding fuel supplied by the fuel tank to the engine through a fuel supplying line, and a fuel return line for returning fuel from the engine to the inside of the fuel tank. The fuel pump may be divided into a pump chamber and an operating chamber, and a vent hole is formed at a case of the fuel pump.

摘要： A canister apparatus having a main body with activated carbon for absorbing fuel vapor; an air tank having a suction port and a filter for filtering harmful materials drawn through the suction port; a first guide pipe for guiding air sucked into the air tank to the main body in order to mix the air with the fuel vapor absorbed in the activated carbon for generating an air-fuel mixture; a float for closing a connecting port between the air tank and the main body to prevent water sucked from the suction port into the air tank from flowing into the body; and a guide for guiding the float upward in the air tank, so diffusion of harmful gas to the atmosphere can be prevented by preventing water from flowing into the main body thereby increasing fuel vapor absorbing efficiency of the activated carbon for air pollution prevention.
