Measuring mass of air sucked into combustion chamber of IC engine - measuring change in air mass in defined vol in defined period and subtracting from flow into induction system during that period

摘要

A method of measuring the quantity of air sucked into the combustion chamber of an i.c. engine contains a device in the induction system measuring flow into that system. The change in the air mass in a defined vol. between the measurement device and the combustion chamber is measured during a defined suction period and is fully or partially subtracted from the air mass measured by the measurement device during the period. USE - Substantially accurate measurement of actual quantity of air sucked into combustion chamber during a defined suction period.
