Abstract
A fuel injection system for internal combustion engines has at least one fuel injector which injects fuel into a combustion chamber delimited by a cylinder wall in which a piston is guided, and it has a spark plug which protrudes into the combustion space, and the fuel injector is designed so that a conical spray jet is produced in the combustion chamber. The conical spray jet has an angle cutout in the area of the spark plug.
Claims15
A fuel injection system for an internal combustion engine, comprising:
- at least one fuel injector for injecting a fuel into a combustion chamber that is delimited by a cylinder wall in which a piston is guided;
- and
- a spark plug extending into the combustion chamber, wherein:
- the at least one fuel injector is configured to produce a fuel-air mixture cloud in the form of a conical spray jet in the combustion chamber, and
- the conical spray jet has an angle cutout in an area of the spark plug.
A method of injecting a fuel into a combustion chamber of an internal combustion engine by using a fuel injector that is delimited by a cylinder wall in which a piston is guided, with a spark plug projecting into the combustion chamber, the method comprising the step of:
- causing the fuel injector to produce a fuel-air mixture cloud in the form of a conical injection jet that has an angle cutout in an area of the spark plug.
