Embodiment Construction

[0027] figure 1 An example of a cylinder or combustion chamber of internal combustion engine 100 is shown. Engine 100 may be controlled at least in part by a control system including controller 12 and input from a vehicle operator 130 via an input device 132 . In this example, input device 132 includes an accelerator pedal and a pedal position sensor 134 for generating a proportional pedal position signal PP. Cylinder (herein also "combustion chamber") 14 of engine 100 may include combustion chamber walls 136 with piston 138 positioned therein. Piston 138 may be coupled to crankshaft 140 such that reciprocating motion of the piston is translated into rotational motion of the crankshaft. Crankshaft 140 may be coupled to at least one drive wheel of a vehicle via a transmission system. Further, a starter motor (not shown) may be coupled to crankshaft 140 via a flywheel to enable a starting operation of engine 100 .

[0028] Cylinders 14 can receive intake air via a series of ...

Abstract

The invention relates to an injection valve for an internal combustion engine of a motor vehicle, which has a cooling device for cooling the injection valve. The cooling device is a thermosyphon cooling device, wherein the thermosyphon cooling device comprises a container volume, and wherein a cooling element has a thermally conductive connection to the container volume.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from German patent application 102015205668.6 filed on March 30, 2015, the entire content of which is hereby incorporated by reference. technical field [0003] The present description generally relates to a system and method for an injection valve of an internal combustion engine of a motor vehicle, the injection valve having a cooling device to cool the injection valve. Background technique [0004] Injection valves (injection nozzles) are valves which on internal combustion engines (e.g. spark ignition or diesel engines) inject fuel into the intake passages by port fuel injection (PFI) or by direct fuel injection (DI ) to inject fuel into the combustion chamber to drive the motor vehicle. In direct fuel injection, the injection valve injects fuel directly into the combustion chamber of the internal combustion engine, while in intake channel fuel injection, the mixture formation does not ...
