  • Method for starting an internal combustion engine
    Patent number: 8406985
    Abstract: A method automatically starts an internal combustion engine having variable valve lift. The internal combustion engine is shut down temporarily in certain driving operating states in order to save fuel and being re-started in the event of a change in the driving operating state. During the engine run-down, the inlet valve is actuated such that the closing time is shifted, with the cylinder being opened via the inlet valve until a pressure compensation has taken place in the cylinder in which an under-pressure would prevail during the engine run-down.
    Type: Grant
