Method for supplying low pressure/vacuum in a combustion engine uses an intake tract with an air inlet and a pulse-load unit to switch between low and excess pressure actions.

摘要

An intake tract (1) with an air inlet (2) flows into a combustion chamber (26) for a combustion engine in an inlet area (20), where an injection jet (22) injects fuel directly into the combustion chamber. An pulse-load unit (17) integrated in the intake tract creates momentary low or excess pressures. An Independent claim is also included for a device for carrying out the method of the present invention.
