摘要:
A method for controlling a spark-ignition engine without a throttle flap is carried out with variable inlet valve opening durations. The method includes the steps of: detecting a speed signal having a value dependent upon the engine speed; detecting an accelerator pedal signal having a value dependent upon the accelerator pedal position; determining the intake valve opening durations as well as the fuel quantity in dependence upon the particular values of the engine speed signal and the accelerator pedal signal; and, determining the ignition angle in the dependence upon the particular values of the engine speed and fuel quantities. The method affords the advantage that for all driving conditions and even for sudden changes of the accelerator pedal signal, the masses of air and fuel are optimally adapted to each other in order to obtain high driving comfort without misfirings and with low toxic gas exhaust.
