An injection nozzle for internal combustion engines has an electrical needle motion sensor, having a cable leading to an evaluation device. To dispose the terminals of the contact lugs of the needle motion sensor and the contact ends of the individual wires of the cable in such a way that they are shake-proof, relieved of tensile strain and protected against splashing water, they are encapsulated in a two-piece insulating shaped part, which is fixed in a recess of the holder body of the injection nozzle. The soldered terminals rest on support bases of pockets in the inner insulating shaped part, and the adjoining parts of the individual wires are bent back and guided in a U around retaining protrusions. The insulating shaped parts and the sheathed cable are fixed by a cover strip or by pins. The preferred field of application is injection nozzles for Diesel engines.

Fuel injection nozzle for internal combustion engines

A pilot burner for a device for burning off solid particles, in particular soot particles, in the exhaust gas of internal combustion engines has a hollow-cylindrical mixture preparation chamber receiving a glow element and a hollow-cylindrical glow plug receiving chamber extending transversely to it and communicating with it through an opening. A fuel inflow line discharges into the receiving chamber and an air supply line discharges into the preparation chamber. To improve mixture preparation and largely avoid carbonization of the glow plug, the glow plug is coaxially surrounded in the vicinity of its coil at a radial distance by a protective sleeve. The fuel inflow line ends at an orifice fitting that protrudes radially into the receiving chamber and discharges immediately in front of the protective sleeve.

A pilot burner for a device for burning off solid particles, especially soot particles, in the exhaust gas of internal combustion engines has a hollow-cylindrical mixture preparation chamber receiving a glow element and extending eccentrically thereto a hollow-cylindrical glow plug receiving chamber. The two chambers communicate with one another via an opening formed by piercing the chamber walls. A fuel inflow line discharges in the receiving chamber and an air supply line discharges into the preparation chamber. To improve the mixture preparation and largely avoid carbonization of the glow plug, the air supply line discharges into two inflow openings having a tangential direction; one inflow opening is located opposite the opening between the two chambers, and the other inflow opening is located near the end face of the preparation chamber having a mixture outlet opening. In obth inflow openings, the combustion air is introduced in the same direction.
