Abstract (en)
[origin: DE4435419A1] A fuel apportioning regulation system for internal combustion engines has means for sensing operation parameters, a program-controlled signal processing installation and means for transmitting a pilot signal to at least an injection valve. In a hot start situation, signal processing allows the pilot signal to be corrected for hot start. Recognition of a hot start situation is based on temperature signals. In addition, a hot start situation is supposed to exist when the internal combustion engine temperature (tmot) is higher than a first threshold (TMH) and the difference between an earlier value of the suction air temperature and its value at the beginning of a new start (delta tans) exceeds a certain value. The hot start situation is supposed to have ended when the internal combustion engine temperature falls below a second threshold TMGHS or when the internal combustion engine has sucked a determined amount or volume of air.
