Problems solved by technology

[0003] The fuel distribution strip known from DE 10 2014 205 179 A1 has the disadvantage that the insert must be produced in a complex manner, since it is designed as a thick-walled pipe with grooves
Furthermore, the known fuel distribution strips are limited by the radial inflow of fuel, resulting in a limited range of applications

Embodiment Construction

[0029] figure 1 A fuel injection system 1 with a fuel distributor 2 corresponding to the first exemplary embodiment is shown schematically. In this exemplary embodiment, fuel injection system 1 has a fuel pump 3 and a metering unit 4 designed as a backing pump 4 . In addition, a high-pressure pump 5 is provided. A fuel pump 3 delivers liquid fuel, in particular gasoline, from a tank 6 to a high-pressure pump 5 . The dosing unit 4 is used for temporarily dosing water from the storage container 7 into the delivered fuel. In this exemplary embodiment, the metering takes place upstream of the high-pressure pump 5 . In a variant, the metering can also take place at the high-pressure pump 5 . Depending on the operating state, liquid fuel or a mixture of liquid fuel and water is then conveyed in line section 8 arranged between fuel distributor 2 and high-pressure pump 4 . Depending on the configuration, the positive water content in the mixture can be predetermined fixedly or ca...

Abstract

The invention relates to a fuel distributor 2, particular a fuel distributor for an external spark-ignition internal combustion engine for compressing a gas mixture. The fuel distributor includes a tubular main body 15, on which a plurality of high-pressure outlets 32-34 are provided. The main body includes at least one dividing wall 21 that at least largely separates an inflow region 25 from a damping region 24 within the main body 15. The main body 15 is made up of at least two profiles 35-37 that are joined to each other. In addition, the invention relates to a method for manufacturing at least one main body 15.

Description

technical field [0001] The invention relates to a fuel distributor, in particular to a fuel distribution strip for an externally ignited internal combustion engine of compressed gas mixture. In particular, the invention relates to the field of fuel injection systems for motor vehicles in which fuel is injected directly into a combustion chamber of an internal combustion engine. Background technique [0002] A fuel distribution rail for an internal combustion engine is known from DE 10 2014 205 179 A1. The known fuel distribution rail has an elongated housing with a cavity, a fuel inflow opening into the cavity, and at least two fuel outflows from the cavity, each for a fuel injector. In this case, a body is arranged in the cavity, which body has a groove connecting the two fuel outflows to one another and in the region of the fuel inflow has a groove radially surrounding the body. A body with two grooves serves as an insert by means of which a direct flow of fuel from the ...
