Abstract

The present invention relates to a supercharged applied ignition internal combustion engine with an exhaust-gas turbocharging and a method for operating an internal combustion engine of said type. A turbocharged internal combustion engine is provided with at least a partially variable valve train on an intake side wherein the intake valves are controlled to optimize the actuation of a second inlet valve in relation to a first inlet valve for different load conditions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to German Patent Application No. 102014210220.0 filed on May 28, 2014 and German Patent Application No. 102014211835.2 filed on June 20, 2014, the entire contents of each of which are incorporated for all purposes This article is for reference only. technical field [0003] The present disclosure relates to methods and systems for controlling intake valve timing of an intake system arranged in an internal combustion engine having exhaust turbocharging and a knock regulator. Background technique [0004] Engines may use boosting devices, such as turbochargers, to increase engine power density. However, engine knock may occur due to increased combustion temperatures during boosted conditions. At higher loads, engine knock may be more limited, which may lead to undesirable late combustion phasing. [0005] Engine knock can be addressed by retarding spark timing such as described in US20...
