Abstract

The invention refers to a method for determining the airflow to an internal combustion engine such as for example a motorcycle engine. The airflow measurement is made via measurement of the pressure in the inlet manifold (2) with a pressure sensor (1) placed between the throttle (4) and the inlet valve (6). The measurement is made at predetermined crankshaft angles whereby at least one pressure measurement takes place near the piston's ((3) lower turning point. The pressure measurement values can be weighted according to the rotation rate of the engine and different measurements at different angles can be made and used to calculate the amount of air contained in the cylinder, the airflow past the throttle or the degree of opening of the throttle.
