Abstract

A vapour-liquid separator of a low-pressure oil-feeding return comprises a vapour-liquid separation chamber, an oil outlet, an oil return port and an exhaust port. The exhaust port locates in the upper part of the vapour-liquid separation chamber and is higher than the position of the oil return port being higher than the position of the oil outlet. The fuel in the vapour-liquid separation chamber flows off the oil outlet to be supplied to the fuel injection device connected in series in the oil-feeding return. The rest fuel returns to the vapour-liquid separation chamber through the oil outlet, in which the vapour-phase composition is exhausted into the oil tank through exhaust port.

Description

technical field [0001] The invention relates to the technical field of engine (internal combustion engine) fuel supply, in particular to a gas-liquid separator suitable for a pulse type electronic fuel injection device with a low-pressure fuel supply circuit. Background technique [0002] Due to the low-boiling components contained in commercial gasoline, these components evaporate back at normal pressure and slightly above air temperature, producing a large number of bubbles. This characteristic of gasoline has caused great harm to the fuel supply system of the engine with a low-pressure fuel supply circuit. This low-pressure fuel supply circuit is suitable for pulse electronic fuel injection devices (Chinese invention patent CN1133810C), and is being used more and more widely in the in-cylinder and out-of-cylinder electronic fuel injection systems of small engines. In order to avoid the interference of fuel vapor on the work of the electronic injection device, a vapor-liq...
