ABSTRACT:
A method of controlling the fuel injection to a combustion chamber (4), comprises the steps of: supplying fuel to a pump (2), which has a piston (7) reciprocating in the a cylinder (6), pressurizing the fuel by applying a force onto the piston (7) by an actuator (8), so that the piston (7) is displaced from a first end position (9) towards a second end position (10), injection of fuel corresponding to a partial volume of the fuel pressurized in the cylinder (6), into the combustion chamber (4), and returning the piston (7) towards the first end position (9) by the pressurized fuel, so that the piston (7) acts with a driving force on the actuator (8). The invention also relates to a fuel injection device for carrying out the method.
