FIELD: engines and pumps.
SUBSTANCE: fuel valve (50) for injecting a low-temperature fuel oil into the combustion chamber of an internal combustion engine with a turbo-supercharging and self-ignition is proposed. The valve comprises an elongate body (52) with a sprayer (54), a fuel inlet (53), a start fluid inlet (78), a valve needle (61). The valve also comprises a fuel chamber (58) surrounding the valve needle (61) and extending to mentioned seat (69), a discharge piston (80), a start piston (83). The discharge piston (80) is connected to the start piston (83) so that they can be moved together, the start chamber (85) is connected to the start fluid inlet (78), and the discharge chamber (82) has an outlet connected to the fuel chamber (58), and an inlet connected to the fuel inlet (53). In addition, the valve has a sealing fluid inlet (70) and a conduit (30) connecting the inlet (70) to the channel (81) for sealing the discharge piston (80) in mentioned channel.
EFFECT: increased efficiency.
