Embodiment Construction

[0019] figure 1 Shown are the curves of the charge signal F of the internal combustion engine, the curves of the over / under fuel quantity M and the influence of the traditional overcompensated air factor value λ during a load change. The theoretical curve of the filling signal F over time t is shown as a rectangular signal curve. It corresponds to the curve of the desired torque. This results in the fuel quantity 11 in the wall oil film of the intake manifold of the internal combustion engine. The actual curve of the filling signal F deviates from the theoretical curve due to intake effects. In addition to the fuel quantity 12 in or from the wall oil film, a fuel quantity 13 for overcompensation during positive load changes, a fuel quantity for overcompensation during negative load changes, etc. 14 and the fuel quantity 15 for deficit compensation during negative load changes. The overcompensated fuel quantity 13 from the positive load change and the undercompensated fuel ...

Abstract

The invention relates to a method for phlegmatizing an internal combustion engine of an automobile. A function of phlegmatizing of the internal combustion engine can be activated according to a load transformation process predicted by prediction data.

Description

technical field [0001] The invention relates to a method for desensitizing an internal combustion engine of a motor vehicle. The invention also relates to a computer program which, when said computer program is run on a computer, performs all the steps of the method according to the invention; and a data carrier storing such a computer program. Finally, the invention relates to a controller which is designed to carry out the method according to the invention. Background technique [0002] The operation of an internal combustion engine is usually optimized at a fixed operating point. For the load change, separate functions are used which are supposed to exhibit the most optimal possible transitions with regard to fuel consumption, exhaust emissions and judder behavior. This transition function has to take into account as many effects as possible and often leads to an unfavorable behavior of the standard. [0003] One aspect in the load shifting process of Otto engines with...
