Abstract

A water distributor (10) for water to be injected into a combustion chamber of an internal combustion engine is provided with a housing (12) that has a receiving chamber (16), wherein the receiving chamber extends in a longitudinal direction (18) of the housing and gradually decreases. An insertion element (14) with an insertion section (20) is provided and the insertion section (20) is inserted into the receiving chamber (16) and extends and decreases in the longitudinal direction in correspondence to the receiving chamber (16). A water inlet (24) and at least one water outlet (26) are provided. A distributor channel (22) connects the water inlet (24) in fluid communication to the at least one water outlet (26). The distributor channel (22) is delimited at least partially by the insertionelement (14). The housing (12) and the insertion element (14) are connected water-tightly to each other at an end face (36) of the housing (12). The housing and the insertion element are made a plastic material.

Description

technical field

[0001] The invention relates to a water distributor for water to be injected into a combustion chamber of an internal combustion engine. Background technique

[0002] Water injection is used in internal combustion engines to increase power and reduce emissions. Water is also used to inject the propellant to be combusted into the combustion chamber, eg the cylinder, of the internal combustion engine. For spraying water, injectors are used, which are supplied with water to be sprayed via water distributors. In order to be able to empty the water distributor in the event of an internal combustion shutdown, for example to avoid freezing, the water supply channel inside the water distributor must be designed with the smallest possible diameter of typically a maximum of 4 mm.

[0003] Commercially available water distributors generally consist of a stainless steel tube onto which the receiver for the injector is welded or brazed. In addition, the holder for fast...

Embodiment Construction

[0040] figure 1 The water dispenser 10 according to the invention in a first embodiment is shown in a perspective view obliquely from above. figure 2 The water dispenser 10 is shown in longitudinal section.

[0041] The water dispenser 10 includes a housing 12 and a push-in element 14 . The housing 12 and the push-in element 14 are made here from the same plastic material, ie glass-fiber-reinforced polypropylene. A receiving chamber 16 is formed in the housing 10 . The receiving chamber 16 tapers in the longitudinal direction 18 . Here, the receiving chamber 16 tapers uniformly along the longitudinal direction 18 , that is to say with a constant rate of reduction of its clear width. The insertion element 14 has an insertion section 20 . The insertion section 20 is accommodated in the receiving chamber 16 , that is to say inserted into it. The insertion section 20 tapers in the longitudinal direction corresponding to the receiving chamber 16 , here uniformly.
