The system (100) is destined to flank the original supply plant of a spontaneously-igniting internal combustion engine comprising: a tank (S), a supply pump (Pa) associated to a delivery tube (T), an injection apparatus (A) and electronic control and command means (C) suitable for piloting the injection apparatus. The system (100) comprises intermittently collecting gas (LPG) in the liquid state from a cylinder (1), from which it is sent by pressure internally of a sealed container (2), where it remains in the liquid state and with a constant predetermined pressure. The gas (LPG) in the liquid state is collected from the sealed container (2) via a delivery pump (3), which increases its pressure by a predetermined gradient and sends it, through a second conduit (20), to the delivery tube (T), downstream of the supply pump (Pa), appropriately deactivated such as to interrupt the flow of the original fuel. The gas (LPG) in the liquid state thus reaches, at a constant pressure not depending on the residual gas in the cylinder (1), the injection apparatus (A) which supplies it to the engine (M), in place of the original fuel. |
