Abstract
In an engine control for an internal combustion engine (1) and in a method, a pressure signal (pA) reproducing the pressure (pA) in one of the combustion chambers (2A) is supplied to an evaluation unit (5) by a pressure signal sensor (4). The evaluation unit (5) uses the pressure signal (pA) to determine the pressure (pB, pC, pD) in at least one other combustion chamber (2B, 2C, 2D).
Claims20
An engine control for an internal combustion engine with a plurality of combustion chambers, comprising:
- at least one pressure signal input to record at least one pressure signal which reproduces the combustion chamber pressure in one of the combustion chambers, and
- an evaluation unit which determines the combustion chamber pressure in at least one other combustion chamber as a function of the pressure signal.
A method for pressure determination of a combustion chamber pressure prevailing in a combustion chamber for an internal combustion engines having several combustion chambers, the method comprising the steps of:
- recording at least one pressure signal which reproduces the combustion chamber pressure in one of the combustion chambers, and
- determining the combustion chamber pressure in at least one other combustion chamber as a function of the pressure signal.
