Abstract
A method of controlling the fuel injection in an internal combustion engine (1) having a piston (3), which passes to and for in a cylinder (2) between an upper and a lower dead center, and an injection nozzle (4), which is disposed in the cylinder (2), the method including the steps whereby a primary injection of fuel is realized in the cylinder (2), which fuel is ignited and causes the piston (3) to be moved in the direction of the lower dead center in the cylinder (2), and whereby a post-injection of a fluid is realized in the cylinder (2). The injection pressure of the fluid in the post-injection is higher than the injection pressure of the fuel in the primary injection.
