  • This abstract for appeared for patent application number 18295172 Titled 'METHOD FOR ADJUSTING A FUEL MASS TO BE INJECTED'

Simplified Explanation

The abstract describes a method for adjusting the amount of fuel injected into an internal combustion engine. The method involves determining the amount of air entering the engine and calculating the appropriate amount of fuel to be injected. The air-fuel ratio in the exhaust system is also determined and adjusted over time. Based on this adjusted ratio and the calculated fuel amount, a first wall film fuel mass is calculated, which is then used to adjust the fuel injection further.


Original Abstract Submitted

A method for adjusting a fuel mass to be injected into an internal combustion engine. The internal combustion engine including an intake tract, at least one cylinder, and an exhaust tract. In the method, an air mass introduced into the internal combustion engine is ascertained and a fuel mass to be injected into the internal combustion engine is determined. An air-fuel ratio in the exhaust tract of the internal combustion engine is determined which is adjusted in time. Based on the time-adjusted air-fuel ratio and the calculated fuel mass to be injected, a first wall film fuel mass is calculated and the fuel mass to be injected is adjusted based on the first wall film fuel mass.
