Abstract

Methods and systems are provided for injecting fuel into a combustion chamber of an engine. In one example, a system may include a hollow cone-shaped injector and a control unit to control the injector. The control unit may detect the position of an inlet valve and trigger the injection process, wherein the injector may be configured to spray fuel out of an inlet duct, through an annular gap, and into the combustion chamber of an engine in an injection process.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to German Patent Application No. 102015200455.4 filed on January 14, 2015, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present description generally relates to methods and systems for injecting fuel into internal combustion engines. Background technique [0004] The present subject matter relates to an engine having a combustion chamber, an intake duct which may be associated with the combustion chamber and which may be used to supply intake air to the combustion chamber, and an intake valve which may be designed to A position closes the intake duct with respect to the combustion chamber and may be further configured to open the annular gap at a second position. The subject engine may further include an injector associated with the combustion chamber for injecting fuel into a motor vehicle having said engine. The subje...
