Abstract:
A fuel distributor, in particular a fuel distribution rail for mixture-compressing, spark-ignited internal combustion engines, includes a base body at which at least one high-pressure input and multiple high-pressure outputs are provided and at least one insert element which is situated in the base body, the insert element separating a distribution area which connects the high-pressure outputs to one another at least essentially from a damping area. The insert element is configured at least essentially as a reshaped insert element. The insert element forms a divider which separates the distribution area at least essentially from the damping area. Furthermore, a fuel injection system including such a fuel distributor is provided.

Abstract:
A water injection device of an internal combustion engine is provided. The water injection device includes a water tank for storing water, and a delivery element for delivering the water. The delivery element is connected to the water tank. The water injection device further includes at least one water injector for injecting water. The at least one water injector is connected to the delivery element. The water injection device further includes a pressure sensor, which is arranged in a line region between the delivery element and the water injector, and a control unit, which is designed to determine, on the basis of pressure data of the pressure sensor, a formation of vapour in the aforementioned line region when the water injector is closed and the delivery element is deactivated.
Abstract:
A method and control unit for a start of an Otto engine operated at low temperatures, using ethanol and/or gasoline, having direct injection. The method includes generating by a high pressure pump a fuel pressure in a high pressure system connected to a high pressure reservoir; a sensor monitoring the fuel pressure in the reservoir and the system; injecting the fuel, by an injector, from the reservoir into a cylinder of the engine, the fuel pressure, an injection quantity and a fuel quantity being specified by a control unit based on, sensor the fuel pressure being specified based on the operating point of the engine up to an upper pressure which is below a starting pressure to which the fuel is increased before the fuel injection, and the fuel pressure in the reservoir and the system being limited to a maximum by an opening pressure of a limiting valve.
